STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH
This invention was made with government support under grant numbers R43AI098327 and AI110578 awarded by the National Institutes of Health (NIH). The United States government has certain rights in the invention.


BACKGROUND
There are two major unsolved problems in the field of antimicrobials: how to develop effective approaches to combat drug-resistant pathogens; and how to treat chronic infections tolerant to antimicrobials. Although drug resistance is a formidable challenge, there at least exists an arsenal of antibiotics, both currently in use and in various stages of the drug development pipeline, which can be used against a variety of pathogenic bacteria. Nevertheless, there remains a significant need for new types of antibiotics for use against emerging drug resistance in bacterial populations.
Unfortunately, the situation with regard to treatment of chronic infections tolerant to antibiotics is very different. Antibiotics are typically effective because of cooperation with the immune system. For example, an antibiotic can eliminate most of the pathogen population or simply stop growth, and then immune system completes the eradication of the infectious bacterial population. This does not work when an exopolymer matrix restricts access of the immune system to the pathogen within a biofilm. The result is a chronic infection, requiring treatment with multiple antibiotics over the course of months to years, accompanied by significant morbidity and mortality. These include endocarditis, osteomyelitis, cystic fibrosis, deep-seated infections, infections of indwelling devices, and dental diseases.
Moreover, all communities of cells produce persisters, dormant variants of the wild type that are tolerant to most antibiotics (Lewis, K. Ann. Rev. Microbiol. (2010) 64:357-372). A lingering chronic infection maintains a large effective population size, favoring development of resistance (Levin, B. R. & Rozen, D. E. Nat. Rev. Microbiol. (2006) 4:556-562) Finding countermeasures against persisters is a considerable unmet need in addressing infectious diseases, and success in finding countermeasures will be significant not only for treatment of chronic infections, but for stemming the spread of resistance as well.
Despite advances in antimicrobial research, there remains a significant need for antibiotic compounds that are potent and effective for the treatment of diseases associated with infection by gram positive and gram negative bacteria. There is also particular need for antimicrobials combatting resistant bacterial strains and for use in treatment of chronic infections, including those associated with biofilm populations comprising dormant persister cells tolerant to currently available antimicrobials. These needs and other needs are satisfied by the present invention.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.


DESCRIPTION
The present invention can be understood more readily by reference to the following detailed description of the invention and the Examples included therein.
Before the present compounds, compositions, articles, systems, devices, and/or methods are disclosed and described, it is to be understood that they are not limited to specific synthetic methods unless otherwise specified, or to particular reagents unless otherwise specified, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, example methods and materials are now described.
All publications mentioned herein are incorporated herein by reference to disclose and describe the methods and/or materials in connection with which the publications are cited.
The publications discussed herein are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the present invention is not entitled to antedate such publication by virtue of prior invention. Further, the dates of publication provided herein can be different from the actual publication dates, which can require independent confirmation.
A. Definitions
In this specification and in the claims which follow, reference will be made to a number of terms which shall be defined herein.
As used herein, nomenclature for compounds, including organic compounds, can be given using common names, IUPAC, IUBMB, or CAS recommendations for nomenclature.
When one or more stereochemical features are present, Cahn-Ingold-Prelog rules for stereochemistry can be employed to designate stereochemical priority, E/Z specification, and the like. One of skill in the art can readily ascertain the structure of a compound if given a name, either by systemic reduction of the compound structure using naming conventions, or by commercially available software, such as CHEMDRAWTM (Cambridgesoft Corporation, U.S.A.).
As used in the specification and in the claims, the term “comprising” can include the aspects “consisting of” and “consisting essentially of.” Thus, for example, an aspect such as “a composition comprising A, B, and C” also includes aspects such as “a composition consisting of A, B, and C” and “a composition consisting essentially of A, B, and C.”
As used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a functional group,” “an alkyl,” or “a residue” includes mixtures of two or more such functional groups, alkyls, or residues, and the like.
Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, a further aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms a further aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. It is also understood that there are a number of values disclosed herein, and that each value is also herein disclosed as “about” that particular value in addition to the value itself. For example, if the value “10” is disclosed, then “about 10” is also disclosed. It is also understood that each unit between two particular units are also disclosed. For example, if 10 and 15 are disclosed, then 11, 12, 13, and 14 are also disclosed.
References in the specification and concluding claims to parts by weight of a particular element or component in a composition denotes the weight relationship between the element or component and any other elements or components in the composition or article for which a part by weight is expressed. Thus, in a compound containing 2 parts by weight of component X and 5 parts by weight component Y, X and Y are present at a weight ratio of 2:5, and are present in such ratio regardless of whether additional components are contained in the compound.
A weight percent (wt. %) of a component, unless specifically stated to the contrary, is based on the total weight of the formulation or composition in which the component is included.
As used herein, the terms “optional” or “optionally” means that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.
As used herein, the term “subject” can be a vertebrate, such as a mammal, a fish, a bird, a reptile, or an amphibian. Thus, the subject of the herein disclosed methods can be a human, non-human primate, horse, pig, rabbit, dog, sheep, goat, cow, cat, guinea pig or rodent. The term does not denote a particular age or sex. Thus, adult and newborn subjects, as well as fetuses, whether male or female, are intended to be covered. In one aspect, the subject is a mammal. A patient refers to a subject afflicted with a disease or disorder. The term “patient” includes human and veterinary subjects.
In some aspects of the disclosed methods, the subject has been diagnosed with a need for treatment of an infectious disease prior to the administering step. In some aspects of the disclosed methods, the subject has been diagnosed with a need for enhancing bacterial ClpP activity prior to the administering step. In some aspects of the disclosed methods, the subject has been diagnosed with having a gram positive or gram negative infection prior to the administering step. In some aspects of the disclosed methods, the subject has been identified with an infectious disease that is treatable by enhancing the activity of bacterial ClpP prior to the administering step. In some aspects of the disclosed methods, the subject has been identified with a gram positive bacterial infection prior to the administering step. In various aspects of the disclosed methods, the subject has been identified with a gram negative bacterial infection prior to the administering step. In one aspect, a subject can be treated prophylactically with a compound or composition disclosed herein, as discussed herein elsewhere.
As used herein, the term “treatment” refers to the medical management of a patient with the intent to cure, ameliorate, stabilize, or prevent a disease, pathological condition, or disorder. This term includes active treatment, that is, treatment directed specifically toward the improvement of a disease, pathological condition, or disorder, and also includes causal treatment, that is, treatment directed toward removal of the cause of the associated disease, pathological condition, or disorder. In addition, this term includes palliative treatment, that is, treatment designed for the relief of symptoms rather than the curing of the disease, pathological condition, or disorder; preventative treatment, that is, treatment directed to minimizing or partially or completely inhibiting the development of the associated disease, pathological condition, or disorder; and supportive treatment, that is, treatment employed to supplement another specific therapy directed toward the improvement of the associated disease, pathological condition, or disorder. In various aspects, the term covers any treatment of a subject, including a mammal (e.g., a human), and includes: (i) preventing the disease from occurring in a subject that can be predisposed to the disease but has not yet been diagnosed as having it; (ii) inhibiting the disease, i.e., arresting its development; or (iii) relieving the disease, i.e., causing regression of the disease. In one aspect, the subject is a mammal such as a primate, and, in a further aspect, the subject is a human. The term “subject” also includes domesticated animals (e.g., cats, dogs, etc.), livestock (e.g., cattle, horses, pigs, sheep, goats, etc.), and laboratory animals (e.g., mouse, rabbit, rat, guinea pig, fruit fly, etc.).
As used herein, the term “prevent” or “preventing” refers to precluding, averting, obviating, forestalling, stopping, or hindering something from happening, especially by advance action. It is understood that where reduce, inhibit or prevent are used herein, unless specifically indicated otherwise, the use of the other two words is also expressly disclosed.
As used herein, the term “diagnosed” means having been subjected to a physical examination by a person of skill, for example, a physician, and found to have a condition that can be diagnosed or treated by the compounds, compositions, or methods disclosed herein. For example, “diagnosed with an infectious disease treatable by enhancing ClpP activity” means having been subjected to a physical examination by a person of skill, for example, a physician, and found to have a condition that can be diagnosed or treated by a compound or composition that can enhance ClpP activity. As a further example, “diagnosed with a need for treatment of an infectious disease” refers to having been subjected to a physical examination by a person of skill, for example, a physician, and found to have a condition characterized by infection with a pathogenic microbe, such as a gram positive or gram negative bacteria.
As used herein, the phrase “identified to be in need of treatment for an infectious disease,” or the like, refers to selection of a subject based upon need for treatment of the infectious disease. For example, a subject can be identified as having a need for treatment of an infectious disease (e.g., an infectious disease related to infection with a pathogenic gram negative or gram positive bacteria) based upon an earlier diagnosis by a person of skill and thereafter subjected to treatment for the infectious disease. It is contemplated that the identification can, in one aspect, be performed by a person different from the person making the diagnosis. It is also contemplated, in a further aspect, that the administration can be performed by one who subsequently performed the administration.
As used herein, the terms “administering” and “administration” refer to any method of providing a pharmaceutical preparation to a subject. Such methods are well known to those skilled in the art and include, but are not limited to, oral administration, transdermal administration, administration by inhalation, nasal administration, topical administration, intravaginal administration, ophthalmic administration, intraaural administration, intracerebral administration, rectal administration, sublingual administration, buccal administration, and parenteral administration, including injectable such as intravenous administration, intra-arterial administration, intramuscular administration, and subcutaneous administration. Administration can be continuous or intermittent. In various aspects, a preparation can be administered therapeutically; that is, administered to treat an existing disease or condition. In further various aspects, a preparation can be administered prophylactically; that is, administered for prevention of a disease or condition.
The term “contacting” as used herein refers to bringing a disclosed compound and a cell, a target protein (e.g. the ClpP endopeptidase), or other biological entity together in such a manner that the compound can affect the activity of the target, either directly; i.e., by interacting with the target itself, or indirectly; i.e., by interacting with another molecule, co-factor, factor, or protein on which the activity of the target is dependent.
As used herein, the terms “effective amount” and “amount effective” refer to an amount that is sufficient to achieve the desired result or to have an effect on an undesired condition. For example, a “therapeutically effective amount” refers to an amount that is sufficient to achieve the desired therapeutic result or to have an effect on undesired symptoms, but is generally insufficient to cause adverse side effects. The specific therapeutically effective dose level for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration; the route of administration; the rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed and like factors well known in the medical arts. For example, it is well within the skill of the art to start doses of a compound at levels lower than those required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved. If desired, the effective daily dose can be divided into multiple doses for purposes of administration. Consequently, single dose compositions can contain such amounts or submultiples thereof to make up the daily dose. The dosage can be adjusted by the individual physician in the event of any contraindications. Dosage can vary, and can be administered in one or more dose administrations daily, for one or several days. Guidance can be found in the literature for appropriate dosages for given classes of pharmaceutical products. In further various aspects, a preparation can be administered in a “prophylactically effective amount”; that is, an amount effective for prevention of a disease or condition.
As used herein, “kit” means a collection of at least two components constituting the kit. Together, the components constitute a functional unit for a given purpose. Individual member components may be physically packaged together or separately. For example, a kit comprising an instruction for using the kit may or may not physically include the instruction with other individual member components. Instead, the instruction can be supplied as a separate member component, either in a paper form or an electronic form which may be supplied on computer readable memory device or downloaded from an internet website, or as recorded presentation.
As used herein, “instruction(s)” means documents describing relevant materials or methodologies pertaining to a kit. These materials may include any combination of the following: background information, list of components and their availability information (purchase information, etc.), brief or detailed protocols for using the kit, trouble-shooting, references, technical support, and any other related documents. Instructions can be supplied with the kit or as a separate member component, either as a paper form or an electronic form which may be supplied on computer readable memory device or downloaded from an internet website, or as recorded presentation. Instructions can comprise one or multiple documents, and are meant to include future updates.
As used herein, the terms “therapeutic agent” include any synthetic or naturally occurring biologically active compound or composition of matter which, when administered to an organism (human or nonhuman animal), induces a desired pharmacologic, immunogenic, and/or physiologic effect by local and/or systemic action. The term therefore encompasses those compounds or chemicals traditionally regarded as drugs, vaccines, and biopharmaceuticals including molecules such as proteins, peptides, hormones, nucleic acids, gene constructs and the like. Examples of therapeutic agents are described in well-known literature references such as the Merck Index (14th edition), the Physicians' Desk Reference (64th edition), and The Pharmacological Basis of Therapeutics (12th edition), and they include, without limitation, medicaments; vitamins; mineral supplements; substances used for the treatment, prevention, diagnosis, cure or mitigation of a disease or illness; substances that affect the structure or function of the body, or pro-drugs, which become biologically active or more active after they have been placed in a physiological environment. For example, the term “therapeutic agent” includes compounds or compositions for use in all of the major therapeutic areas including, but not limited to, adjuvants; anti-infectives such as antibiotics and antiviral agents; analgesics and analgesic combinations, anorexics, anti-inflammatory agents, anti-epileptics, local and general anesthetics, hypnotics, sedatives, antipsychotic agents, neuroleptic agents, antidepressants, anxiolytics, antagonists, neuron blocking agents, anticholinergic and cholinomimetic agents, antimuscarinic and muscarinic agents, antiadrenergics, antiarrhythmics, antihypertensive agents, hormones, and nutrients, antiarthritics, antiasthmatic agents, anticonvulsants, antihistamines, antinauseants, antineoplastics, antipruritics, antipyretics; antispasmodics, cardiovascular preparations (including calcium channel blockers, beta-blockers, beta-agonists and antiarrythmics), antihypertensives, diuretics, vasodilators; central nervous system stimulants; cough and cold preparations; decongestants; diagnostics; hormones; bone growth stimulants and bone resorption inhibitors; immunosuppressives; muscle relaxants; psychostimulants; sedatives; tranquilizers; proteins, peptides, and fragments thereof (whether naturally occurring, chemically synthesized or recombinantly produced); and nucleic acid molecules (polymeric forms of two or more nucleotides, either ribonucleotides (RNA) or deoxyribonucleotides (DNA) including both double- and single-stranded molecules, gene constructs, expression vectors, antisense molecules and the like), small molecules (e.g., doxorubicin) and other biologically active macromolecules such as, for example, proteins and enzymes. The agent may be a biologically active agent used in medical, including veterinary, applications and in agriculture, such as with plants, as well as other areas. The term therapeutic agent also includes without limitation, medicaments; vitamins; mineral supplements; substances used for the treatment, prevention, diagnosis, cure or mitigation of disease or illness; or substances which affect the structure or function of the body; or pro-drugs, which become biologically active or more active after they have been placed in a predetermined physiological environment.
As used herein, “EC50,” is intended to refer to the concentration of a substance (e.g., a compound or a drug) that is required for 50% activation or enhancement of a biological process, or component of a process. For example, EC50 can refer to the concentration of a compound that provokes a response halfway between the baseline and maximum response in an appropriate assay of the target activity. For example, an EC50 for the ClpP endopeptidase can be determined in an in vitro assay system. Such in vitro assay systems include assay such as the Casein-BODIPY digestion assay as described herein.
As used herein, “IC50,” is intended to refer to the concentration of a substance (e.g., a compound or a drug) that is required for 50% inhibition of a biological process, or component of a process, including a protein, subunit, organelle, ribonucleoprotein, etc. In one aspect, an IC50 can refer to the concentration of a substance that is required for 50% inhibition in vivo, as further defined elsewhere herein. In a further aspect, IC50 refers to the half maximal (50%) inhibitory concentration (IC) of a substance.
The term “pharmaceutically acceptable” describes a material that is not biologically or otherwise undesirable, i.e., without causing an unacceptable level of undesirable biological effects or interacting in a deleterious manner.
As used herein, the term “derivative” refers to a compound having a structure derived from the structure of a parent compound (e.g., a compound disclosed herein) and whose structure is sufficiently similar to those disclosed herein and based upon that similarity, would be expected by one skilled in the art to exhibit the same or similar activities and utilities as the claimed compounds, or to induce, as a precursor, the same or similar activities and utilities as the claimed compounds. Exemplary derivatives include salts, esters, amides, salts of esters or amides, and N-oxides of a parent compound.
As used herein, the term “pharmaceutically acceptable carrier” refers to sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, as well as sterile powders for reconstitution into sterile injectable solutions or dispersions just prior to use. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or vehicles include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol and the like), carboxymethylcellulose and suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersions and by the use of surfactants. These compositions can also contain adjuvants such as preservatives, wetting agents, emulsifying agents and dispersing agents. Prevention of the action of microorganisms can be ensured by the inclusion of various antibacterial and antifungal agents such as paraben, chlorobutanol, phenol, sorbic acid and the like. It can also be desirable to include isotonic agents such as sugars, sodium chloride and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the inclusion of agents, such as aluminum monostearate and gelatin, which delay absorption. Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide, poly(orthoesters) and poly(anhydrides). Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues. The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable media just prior to use. Suitable inert carriers can include sugars such as lactose. Desirably, at least 95% by weight of the particles of the active ingredient have an effective particle size in the range of 0.01 to 10 micrometers.
A residue of a chemical species, as used in the specification and concluding claims, refers to the moiety that is the resulting product of the chemical species in a particular reaction scheme or subsequent formulation or chemical product, regardless of whether the moiety is actually obtained from the chemical species. Thus, an ethylene glycol residue in a polyester refers to one or more —OCH2CH2O— units in the polyester, regardless of whether ethylene glycol was used to prepare the polyester. Similarly, a sebacic acid residue in a polyester refers to one or more —CO(CH2)8CO— moieties in the polyester, regardless of whether the residue is obtained by reacting sebacic acid or an ester thereof to obtain the polyester.
As used herein, the term “substituted” is contemplated to include all permissible substituents of organic compounds. In a broad aspect, the permissible substituents include acyclic and cyclic, branched and unbranched, carbocyclic and heterocyclic, and aromatic and nonaromatic substituents of organic compounds. Illustrative substituents include, for example, those described below. The permissible substituents can be one or more and the same or different for appropriate organic compounds. For purposes of this disclosure, the heteroatoms, such as nitrogen, can have hydrogen substituents and/or any permissible substituents of organic compounds described herein which satisfy the valences of the heteroatoms. This disclosure is not intended to be limited in any manner by the permissible substituents of organic compounds. Also, the terms “substitution” or “substituted with” include the implicit proviso that such substitution is in accordance with permitted valence of the substituted atom and the substituent, and that the substitution results in a stable compound, e.g., a compound that does not spontaneously undergo transformation such as by rearrangement, cyclization, elimination, etc. It is also contemplated that, in certain aspects, unless expressly indicated to the contrary, individual substituents can be further optionally substituted (i.e., further substituted or unsubstituted).
In defining various terms, “A1,” “A2,” “A3,” and “A4” are used herein as generic symbols to represent various specific substituents. These symbols can be any substituent, not limited to those disclosed herein, and when they are defined to be certain substituents in one instance, they can, in another instance, be defined as some other substituents.
The term “aliphatic” or “aliphatic group,” as used herein, denotes a hydrocarbon moiety that may be straight-chain (i.e., unbranched), branched, or cyclic (including fused, bridging, and spirofused polycyclic) and may be completely saturated or may contain one or more units of unsaturation, but which is not aromatic. Unless otherwise specified, aliphatic groups contain 1-20 carbon atoms. Aliphatic groups include, but are not limited to, linear or branched, alkyl, alkenyl, and alkynyl groups, and hybrids thereof such as (cycloalkyl)alkyl, (cycloalkenyl)alkyl or (cycloalkyl)alkenyl.
The term “alkyl” as used herein is a branched or unbranched saturated hydrocarbon group of 1 to 24 carbon atoms, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, s-butyl, t-butyl, n-pentyl, isopentyl, s-pentyl, neopentyl, hexyl, heptyl, octyl, nonyl, decyl, dodecyl, tetradecyl, hexadecyl, eicosyl, tetracosyl, and the like. The alkyl group can be cyclic or acyclic. The alkyl group can be branched or unbranched. The alkyl group can also be substituted or unsubstituted. For example, the alkyl group can be substituted with one or more groups including, but not limited to, alkyl, cycloalkyl, alkoxy, amino, ether, halide, hydroxy, nitro, silyl, sulfo-oxo, or thiol, as described herein. A “lower alkyl” group is an alkyl group containing from one to six (e.g., from one to four) carbon atoms. The term alkyl group can also be a C1 alkyl, C1-C2 alkyl, C1-C3 alkyl, C1-C4 alkyl, C1-C5 alkyl, C1-C6 alkyl, C1-C7 alkyl, C1-C8 alkyl, C1-C9 alkyl, C1-C10 alkyl, and the like up to and including a C1-C24 alkyl.
Throughout the specification “alkyl” is generally used to refer to both unsubstituted alkyl groups and substituted alkyl groups; however, substituted alkyl groups are also specifically referred to herein by identifying the specific substituent(s) on the alkyl group. For example, the term “halogenated alkyl” or “haloalkyl” specifically refers to an alkyl group that is substituted with one or more halide, e.g., fluorine, chlorine, bromine, or iodine. Alternatively, the term “monohaloalkyl” specifically refers to an alkyl group that is substituted with a single halide, e.g. fluorine, chlorine, bromine, or iodine. The term “polyhaloalkyl” specifically refers to an alkyl group that is independently substituted with two or more halides, i.e. each halide substituent need not be the same halide as another halide substituent, nor do the multiple instances of a halide substituent need to be on the same carbon. The term “alkoxyalkyl” specifically refers to an alkyl group that is substituted with one or more alkoxy groups, as described below. The term “aminoalkyl” specifically refers to an alkyl group that is substituted with one or more amino groups. The term “hydroxyalkyl” specifically refers to an alkyl group that is substituted with one or more hydroxy groups. When “alkyl” is used in one instance and a specific term such as “hydroxyalkyl” is used in another, it is not meant to imply that the term “alkyl” does not also refer to specific terms such as “hydroxyalkyl” and the like.
This practice is also used for other groups described herein. That is, while a term such as “cycloalkyl” refers to both unsubstituted and substituted cycloalkyl moieties, the substituted moieties can, in addition, be specifically identified herein; for example, a particular substituted cycloalkyl can be referred to as, e.g., an “alkylcycloalkyl.” Similarly, a substituted alkoxy can be specifically referred to as, e.g., a “halogenated alkoxy,” a particular substituted alkenyl can be, e.g., an “alkenylalcohol,” and the like. Again, the practice of using a general term, such as “cycloalkyl,” and a specific term, such as “alkylcycloalkyl,” is not meant to imply that the general term does not also include the specific term.

The term “leaving group” refers to an atom (or a group of atoms) with electron withdrawing ability that can be displaced as a stable species, taking with it the bonding electrons. Examples of suitable leaving groups include halides and sulfonate esters, including, but not limited to, triflate, mesylate, tosylate, and brosylate.
The terms “hydrolysable group” and “hydrolysable moiety” refer to a functional group capable of undergoing hydrolysis, e.g., under basic or acidic conditions. Examples of hydrolysable residues include, without limitation, acid halides, activated carboxylic acids, and various protecting groups known in the art (see, for example, “Protective Groups in Organic Synthesis,” T. W. Greene, P. G. M. Wuts, Wiley-Interscience, 1999).
The term “organic residue” defines a carbon containing residue, i.e., a residue comprising at least one carbon atom, and includes but is not limited to the carbon-containing groups, residues, or radicals defined hereinabove. Organic residues can contain various heteroatoms, or be bonded to another molecule through a heteroatom, including oxygen, nitrogen, sulfur, phosphorus, or the like. Examples of organic residues include but are not limited alkyl or substituted alkyls, alkoxy or substituted alkoxy, mono or di-substituted amino, amide groups, etc. Organic residues can preferably comprise 1 to 18 carbon atoms, 1 to 15, carbon atoms, 1 to 12 carbon atoms, 1 to 8 carbon atoms, 1 to 6 carbon atoms, or 1 to 4 carbon atoms. In a further aspect, an organic residue can comprise 2 to 18 carbon atoms, 2 to 15, carbon atoms, 2 to 12 carbon atoms, 2 to 8 carbon atoms, 2 to 4 carbon atoms, or 2 to 4 carbon atoms.
A very close synonym of the term “residue” is the term “radical,” which as used in the specification and concluding claims, refers to a fragment, group, or substructure of a molecule described herein, regardless of how the molecule is prepared. For example, a 2,4-thiazolidinedione radical in a particular compound has the structure:




regardless of whether thiazolidinedione is used to prepare the compound. In some embodiments the radical (for example an alkyl) can be further modified (i.e., substituted alkyl) by having bonded thereto one or more “substituent radicals.” The number of atoms in a given radical is not critical to the present invention unless it is indicated to the contrary elsewhere herein.

“Organic radicals,” as the term is defined and used herein, contain one or more carbon atoms. An organic radical can have, for example, 1-26 carbon atoms, 1-18 carbon atoms, 1-12 carbon atoms, 1-8 carbon atoms, 1-6 carbon atoms, or 1-4 carbon atoms. In a further aspect, an organic radical can have 2-26 carbon atoms, 2-18 carbon atoms, 2-12 carbon atoms, 2-8 carbon atoms, 2-6 carbon atoms, or 2-4 carbon atoms. Organic radicals often have hydrogen bound to at least some of the carbon atoms of the organic radical. One example, of an organic radical that comprises no inorganic atoms is a 5, 6, 7, 8-tetrahydro-2-naphthyl radical. In some embodiments, an organic radical can contain 1-10 inorganic heteroatoms bound thereto or therein, including halogens, oxygen, sulfur, nitrogen, phosphorus, and the like. Examples of organic radicals include but are not limited to an alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, mono-substituted amino, di-substituted amino, acyloxy, cyano, carboxy, carboalkoxy, alkylcarboxamide, substituted alkylcarboxamide, dialkylcarboxamide, substituted dialkylcarboxamide, alkylsulfonyl, alkylsulfinyl, thioalkyl, thiohaloalkyl, alkoxy, substituted alkoxy, haloalkyl, haloalkoxy, aryl, substituted aryl, heteroaryl, heterocyclic, or substituted heterocyclic radicals, wherein the terms are defined elsewhere herein. A few non-limiting examples of organic radicals that include heteroatoms include alkoxy radicals, trifluoromethoxy radicals, acetoxy radicals, dimethylamino radicals and the like.
“Inorganic radicals,” as the term is defined and used herein, contain no carbon atoms and therefore comprise only atoms other than carbon. Inorganic radicals comprise bonded combinations of atoms selected from hydrogen, nitrogen, oxygen, silicon, phosphorus, sulfur, selenium, and halogens such as fluorine, chlorine, bromine, and iodine, which can be present individually or bonded together in their chemically stable combinations. Inorganic radicals have 10 or fewer, or preferably one to six or one to four inorganic atoms as listed above bonded together. Examples of inorganic radicals include, but not limited to, amino, hydroxy, halogens, nitro, thiol, sulfate, phosphate, and like commonly known inorganic radicals. The inorganic radicals do not have bonded therein the metallic elements of the periodic table (such as the alkali metals, alkaline earth metals, transition metals, lanthanide metals, or actinide metals), although such metal ions can sometimes serve as a pharmaceutically acceptable cation for anionic inorganic radicals such as a sulfate, phosphate, or like anionic inorganic radical. Inorganic radicals do not comprise metalloids elements such as boron, aluminum, gallium, germanium, arsenic, tin, lead, or tellurium, or the noble gas elements, unless otherwise specifically indicated elsewhere herein.
Compounds described herein can contain one or more double bonds and, thus, potentially give rise to cis/trans (E/Z) isomers, as well as other conformational isomers. Unless stated to the contrary, the invention includes all such possible isomers, as well as mixtures of such isomers.
Unless stated to the contrary, a formula with chemical bonds shown only as solid lines and not as wedges or dashed lines contemplates each possible isomer, e.g., each enantiomer and diastereomer, and a mixture of isomers, such as a racemic or scalemic mixture. Compounds described herein can contain one or more asymmetric centers and, thus, potentially give rise to diastereomers and optical isomers. Unless stated to the contrary, the present invention includes all such possible diastereomers as well as their racemic mixtures, their substantially pure resolved enantiomers, all possible geometric isomers, and pharmaceutically acceptable salts thereof. Mixtures of stereoisomers, as well as isolated specific stereoisomers, are also included. During the course of the synthetic procedures used to prepare such compounds, or in using racemization or epimerization procedures known to those skilled in the art, the products of such procedures can be a mixture of stereoisomers.
Many organic compounds exist in optically active forms having the ability to rotate the plane of plane-polarized light. In describing an optically active compound, the prefixes D and L or R and S are used to denote the absolute configuration of the molecule about its chiral center(s). The prefixes d and 1 or (+) and (−) are employed to designate the sign of rotation of plane-polarized light by the compound, with (−) or meaning that the compound is levorotatory. A compound prefixed with (+) or d is dextrorotatory. For a given chemical structure, these compounds, called stereoisomers, are identical except that they are non-superimposable mirror images of one another. A specific stereoisomer can also be referred to as an enantiomer, and a mixture of such isomers is often called an enantiomeric mixture. A 50:50 mixture of enantiomers is referred to as a racemic mixture. Many of the compounds described herein can have one or more chiral centers and therefore can exist in different enantiomeric forms. If desired, a chiral carbon can be designated with an asterisk (*). When bonds to the chiral carbon are depicted as straight lines in the disclosed formulas, it is understood that both the (R) and (S) configurations of the chiral carbon, and hence both enantiomers and mixtures thereof, are embraced within the formula. As is used in the art, when it is desired to specify the absolute configuration about a chiral carbon, one of the bonds to the chiral carbon can be depicted as a wedge (bonds to atoms above the plane) and the other can be depicted as a series or wedge of short parallel lines is (bonds to atoms below the plane). The Cahn-Inglod-Prelog system can be used to assign the (R) or (S) configuration to a chiral carbon.
Compounds described herein comprise atoms in both their natural isotopic abundance and in non-natural abundance. The disclosed compounds can be isotopically-labeled or isotopically-substituted compounds identical to those described, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, sulfur, fluorine and chlorine, such as 2H, 3H, 13C, 14C 15N, 18O, 17O, 35S, 18F, and 36Cl, respectively. Compounds further comprise prodrugs thereof and pharmaceutically acceptable salts of said compounds or of said prodrugs which contain the aforementioned isotopes and/or other isotopes of other atoms are within the scope of this invention. Certain isotopically-labeled compounds of the present invention, for example those into which radioactive isotopes such as 3H and 14C are incorporated, are useful in drug and/or substrate tissue distribution assays. Tritiated, i.e., 3H, and carbon-14, i.e., 14C, isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium, i.e., 2H, can afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements and, hence, may be preferred in some circumstances. Isotopically labeled compounds of the present invention and prodrugs thereof can generally be prepared by carrying out the procedures below, by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent.
The compounds described in the invention can be present as a solvate. In some cases, the solvent used to prepare the solvate is an aqueous solution, and the solvate is then often referred to as a hydrate. The compounds can be present as a hydrate, which can be obtained, for example, by crystallization from a solvent or from aqueous solution. In this connection, one, two, three or any arbitrary number of solvent or water molecules can combine with the compounds according to the invention to form solvates and hydrates. Unless stated to the contrary, the invention includes all such possible solvates.
The term “co-crystal” means a physical association of two or more molecules which owe their stability through non-covalent interaction. One or more components of this molecular complex provide a stable framework in the crystalline lattice. In certain instances, the guest molecules are incorporated in the crystalline lattice as anhydrates or solvates, see e.g. “Crystal Engineering of the Composition of Pharmaceutical Phases. Do Pharmaceutical Co-crystals Represent a New Path to Improved Medicines?” Almarasson, O., et al., The Royal Society of Chemistry, 1889-1896, 2004. Examples of co-crystals include p-toluenesulfonic acid and benzenesulfonic acid.
It is also appreciated that certain compounds described herein can be present as an equilibrium of tautomers. For example, ketones with an α-hydrogen can exist in an equilibrium of the keto form and the enol form.




Likewise, amides with an N-hydrogen can exist in an equilibrium of the amide form and the imidic acid form. Unless stated to the contrary, the invention includes all such possible tautomers.

It is known that chemical substances form solids which are present in different states of order which are termed polymorphic forms or modifications. The different modifications of a polymorphic substance can differ greatly in their physical properties. The compounds according to the invention can be present in different polymorphic forms, with it being possible for particular modifications to be metastable. Unless stated to the contrary, the invention includes all such possible polymorphic forms.
In some aspects, a structure of a compound can be represented by a formula:




which is understood to be equivalent to a formula:





wherein n is typically an integer. That is, Rn is understood to represent five independent substituents, Rn(a), Rn(b), Rn(c), Rn(d), and Rn(e). By “independent substituents,” it is meant that each R substituent can be independently defined. For example, if in one instance Rn(a) is halogen, then Rn(b) is not necessarily halogen in that instance.

3. ClpP Enhancer Activity
ClpP protease is normally fairly selective—it clears misfolded proteins that are fed into the enzyme by accessory ClpA, ClpC and ClpX subunits that use ATP to specifically recognize, unfold and translocate the substrate into the ClpP proteolytic chamber for degradation (Gottesman, S. & Maurizi, M. R. Microbiol Rev (1992) 56:592-621; Gottesman, S., et al. Genes & development (1998) 12:1338-1347). Acyldepsipeptide (ADEP) is an antimicrobial lipopeptide that binds to the ClpX activation domain of ClpP, widening the entry pore on the proximal and distal ends of the protein (Sass, P., et al. Proc. Natl. Acad. Sci. (2011) 108:17474-17479). The result is that ClpP becomes an unregulated protease that does not require ATP, which forces even dormant cells to self-digest. Without wishing to be bound by a particular theory, the disclosed compounds of the present invention are believed to bind to the activation domain of ClpP and exert their antibacterial activity by opening the entry to the proteolytic chamber of ClpP, thereby resulting in self-digestion of target bacteria.

1. Route I
In one aspect, synthetic intermediates useful for the synthesis of substituted urea depsipeptide analogs of the present invention can be prepared generically by the synthetic scheme as shown below.




Compounds are represented in generic form, with substituents as noted in compound descriptions elsewhere herein. A more specific example is set forth below.




In one aspect, compounds of the present invention, e.g., compounds of Formula 1.6, can be prepared beginning with reaction of compounds of Formulas 1.1 and 1.2 to yield compounds of Formula 1.3. The coupling of 1.1 and 1.2 can be carried out using an appropriate dehydrating (or coupling) agent, e.g., EDC (N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide), with an appropriate additive agent, e.g., HOBt (N-hydroxybenzotriazole), in a suitable solvent, e.g., DMF, and the reaction carried out at a suitable temperature, e.g., about 15° C. to about 30° C., for an appropriate period of time to complete the reaction, e.g., about 10 hr to about 30 hr. The next step of the synthesis sequence involves a multi-step reaction that can be carried out in a single reaction vessel. In the first step, the product from the preceding reaction, 1.3, is treated with an acid, e.g., HCl, in a suitable solvent, e.g., DMF, and carried out at a suitable temperature, e.g., about 15° C. to about 30° C., for a suitable period of time to complete the reaction, e.g., about 30 min to about 120 min. The next is the coupling of the Boc-protected 1.4 with 1.3, which was deprotected in the prior step with HCl. The coupling reaction involves a suitable catalyst, e.g. HOBt, with a suitable base, e.g., DIEA, and carried out at a suitable temperature, e.g., about 15° C. to about 30° C., for an appropriate period of time to complete the reaction, e.g., about 10 h to about 30 h.

Compound B was treated with 4N hydrocholoride acid in dioaxane to afford free amine C, which was coupled with appropriate isocyanate under microwave irradiation in the presence of triethylamine to give substituted urea depsipeptide analogs 1-14 (for coupling of an isocyanate under microwave irradiation see North, E. J., et al. Bioorganic & Medicinal Chemistry (2013) 21(9):2587-2599).
Briefly, Ar—NCO (about 1.2 eq.), compound C (about 1 eq), and triethylamine (about 3.6 or alternatively about 4.8 eq.) were mixed in THF/DMF (v/v=1:1, 2 mL) in a microwave safe tube and stirred at 200° C. for 10 min. The solvents were removed under reduced pressure and the crude residue was purified by reverse-phase flash column chromatography using water to acetonitrile gradient. The fractions containing desired compound were pooled and dried to the desired afford target compounds.

4. General Synthesis of Urea Analogs 15-37




The target compound was synthesized from intermediate A, which was deprotected by hydrogenation in the presence of palladium on carbon following by coupling with Boc-L-phenylalanine to give compound B (for general methods for coupling of Boc-L-phenylalanine see (a) Hinzen, B., et al. ChemMedChem (2006) 1(7):689-693; and (b) U.S. Pat. No. 4,492,650). Compound B was treated with 4N hydrocholoride acid in dioaxane to afford free amine C, which was coupled with appropriate isocyanate under microwave irradiation in the presence of triethylamine to give substituted urea depsipeptide analogs 15-48 (for coupling of an isocyanate under microwave irradiation see North, E. J., et al. Bioorganic & Medicinal Chemistry (2013) 21(9):2587-2599).
Briefly, Ar—NCO (about 1.2 eq.), compound C (about 1 eq), and triethylamine (about 3.6 or alternatively about 4.8 eq.) were mixed in THF/DMF (v/v=1:1, 2 mL) in a microwave safe tube and stirred at 200° C. for 10 min. The solvents were removed under reduced pressure and the crude residue was purified by reverse-phase flash column chromatography using water to acetonitrile gradient. The fractions containing desired compound were pooled and dried to the desired afford target compounds. Table 2 below provides information for the particular substituted Boc-L-phenylalanine derivative and aryl isocyanate used in the general scheme shown above. The substituent groups are as follows:

6. Casein-Bodipy Assay
The compounds were assayed in a casein digestion assay in order to determine their effect on ClpP activation. Briefly, the assay was carried out using S. aureus ClpP (“Sa-ClpP”) overexpressed in E. coli BL21 (DE3) and purified in a two-step process. Purity of the protein was assessed through SDS PAGE analysis. EC50 evaluations were conducted in triplicate in a 20 μl assay format using a method adapted from Maurizi et al. (Methods Enzymol. (1994) 244:314-331.). Each well contained 10 μM saClpP, 25 μg/ml BODIPY FL casein (Invitrogen Corporation, San Diego, Calif.), and test compound in concentrations ranging between 0-100 μM in assay buffer (50 mM Tris pH 8, 200 mM KCl, and 1 mM TCEP). The reaction took place at 37° C. Fluorescence (excitation 485 nm; emission 528 nm) was measured in five minute intervals over a 45 min period using a BioTek HT fluorescence microplate reader (BioTek Instruments, Inc., Winooski, Vt.). Velocity of each reaction was calculated and data was fit to a dose response curve using GraphPad Prism® software (GraphPad Software, Inc., La Jolla, Calif.). EC50 is the effective concentration of compound which causes 50% activation of S. aureus ClpP in the foregoing BODIPY FL casein assay.
Alternatively, the assay was carried out using EnzCheck Protease Assay (Molecular Probes, Catalog #E6638). The assay was performed in black 384 well, flat bottom, low volume plates (Greiner Bio-One, Monroe, N.C., catalog #784076). 10 μL of Tris.HCl buffer, pH 8.0 with 0.01% Triton X-100 was pipetted into each well using a Well-Mate (Thermo Scientific, Waltham, Mass.). 0.4 μL test compounds or controls (2% DMSO v/v) were added to each well using a Biomek FX liquid handling robot (Beckman Coulter, Indianapolis Ind.). After addition of test compounds and controls, 10 μL of master mix containing 2 μM Sa-ClpP and 2 μM substrate (Bodipy-FL labeled casein) in Tris*HCl buffer, pH 8.0 with 0.01% (v/v) Triton X-100, was pipetted into each well. All assays were performed in triplicate, under linear velocity conditions. Increase in fluorescent signal following activation of Sa-ClpP by test compounds and controls was measured over time period of 30 mins using filters with excitation at 485±15 nm and emission at 520±25 nm on a PHERAstar FS Multilabel reader (BMG, Cary, N.C.). Instrument gains and enzyme linear velocity conditions were determined and validated using ADEP4, a known Sa-ClpP activator. Data analysis was done by measuring rate of casein degradation over time (slopes). Computed degradation rates (slopes) were normalized to positive (ADEP4) or negative (DMSO) controls. Using nonlinear regression curve fitting EC50 values and % activation were determined using the equation “log [agonist]vs. Response-variable slope (four parameters)-symmetrical” in the program Prism 6 (GraphPad Software, La Jolla, Calif. USA, www.graphpad.com).
7. ADEP Displacement Fluorescence Polarization Assay
A fluorescence polarization (FP) assay was used to determine the activity of the disclosed compounds in displacing an ADEP analogue from ClpP. Briefly, the assay was performed in black 384 well, flat bottom, low volume plates (Greiner Bio-One, Monroe, N.C., catalog #784076). 20 μL of a pre-equilibrated (1 hr, room temperature) master mix (1 μM Sa-ClpP, 2% DMSO (v/v) and 50 nM FP probe in Tris*HCl, pH 8.0)) was pipetted into each well using a Well-Mate (Thermo Scientific, Waltham, Mass.). Sa-ClpP was prepared as described above for the ClpP activation assay. The FP probe was ADEP 2591 (structure shown above). The ADEP 2591 comprises a TAMRA fluorophore linked to a core based on modified ADEP 2378 via a short alkyl linker. Using pin transfer, approximately 0.4 μL (2% v/v DMSO) of each compound or control was added per well. After addition of compounds and controls, plates were allowed to incubate for an additional 120 minutes at room temperature. All assays were performed in triplicate. Polarization was monitored using an EnVision Multilabel reader (Perkin-Elmer, Waltham, Mass.) by exciting the FP probe at 530±25 nm, and monitoring fluorescence intensity of both parallel and perpendicular polarized light at 579±25 nm. Readout was in millipolarization units (mP).
Signal gain and G factors were determined in wells containing 20 μM ADEP 2378, which had been previously verified (data not shown) as containing completely unbound ADEP 2591. Data collected was normalized to values obtained from positive (20 μM ADEP 2378) or negative (DMSO) controls. Curves were fit with non-linear regression using the equation “log [inhibitor]vs. Response-variable slope (four parameters)-symmetrical” in the program Prism 6 (GraphPad Software, La Jolla, Calif. USA, www.graphpad.com). The structures for ADEP 2378 and ADEP 2591 are shown above. ADEP 2378 is (E)-N-((S)-1-(((2R,6S,8aS,14aS,20S,23aS)-2,6-dimethyl-5,8,14,19,23-pentaoxooctadecahydro-1H,5H,14H,19H-pyrido[2,1-i]dipyrrolo[2,1-c:2′,1′-1][1]oxa[4,7,10,13]tetraazacyclohexadecin-20-yl)amino)-1-oxo-3-phenylpropan-2-yl)pent-2-enamide. ADEP 2591 is 5-(3-(3-((6S,9S,11aS,17S,20aS)-6,10-dimethyl-5,8,11,16,20-pentaoxo-17-((S)-2-((E)-pent-2-enamido)-3-phenylpropanamido)hexadecahydro-1H,5H,16H-dipyrrolo[2,1-c:2′,1′-1][1]oxa[4,7,10,13]tetraazacyclohexadecin-9-yl)propyl)thioureido)-2-(6-(dimethylamino)-3-(dimethyliminio)-3H-xanthen-9-yl)benzoate.
8. Cytotoxicity Assay
Cytotoxicity was determined by determining the effect of compounds on cell viability. Vero (kidney epithelial cells; ATCC CCL-81) monolayers were trypsinized and 5000 cells/well were seeded (10-15% confluency) into white-wall, flat bottom 96 well microwell plates (Corning) using enriched Dulbecco's Modified Eagle's Medium (Hyclone: DMEM/High Glucose) containing 10% Fetal Bovine Serum (ATCC-30-2020). Plates were incubated overnight at 37° C. in the presence of 5% CO2. Drug-free media was then replaced with media containing serial dilutions of test compound or DMSO carrier. After an additional 72 hours of incubation, viability was indirectly measured using the CellTiter-Glo® Luminescent Cell Viability (Promega) assay. Assay plates were read at peak emission wavelength of 560 nm using a EnVision® Multilabel Plate Reader (Perkin Elmer) or PHERAstar FS Multilabel reader (BMG, Cary, N.C.). The concentration of test compounds that inhibited growth by 50% (IC50 value) was computed using nonlinear regression based fitting of inhibition curves using log [inhibitor]vs. response-variable slope (four parameters)—symmetrical equation, in GraphPad Prism version 6 [GraphPad Software, La Jolla Calif. USA, www.graphpad.com]. For each experiment, compounds were tested in duplicate. IC50 values presented are the range of two biologically independent experiments.
9. Microsomal Metabolic Stability Determination
Compounds were initially prepared by dissolving them into DMSO at a final concentration of 10 mM. NADPH regenerating solutions A and B and mouse liver microsomes (CD-1) were obtained from BD Gentest (Woburn, Mass.). Ninety-six well deep well plates were obtained from MidWest Scientific Inc (Valley Park, Mo.).
Sample preparation for microsomal stability was modified from methods of Di, L., et al., Int J Pharm. 2005 Jun. 13; 297(1-2): 110-9. A set of incubation times of 0, 15, 30, 60, 120, and 240 minutes were used. Mouse liver microsomal solutions were prepared by adding 58 μL of concentrated human or mouse liver microsomes (20 mg/mL protein concentration) to 1.756 mL of 0.1 M potassium phosphate buffer (pH 7.4) and 5 μL of 0.5 M EDTA to make a 0.6381 mg/mL (protein) microsomal solution. NADPH regenerating agent contained 113 μL of NADPH A, 23 μL of NADPH B, and 315 μL of 0.1 M potassium phosphate buffer (pH 7.4). The diluted test compound solutions (2 μL) were each added directly to a 1.79 mL of liver microsomal solution. This solution was mixed and 90 μL was transferred to 6 time points plates (each in triplicate wells). For the time 0 plate, 225 μL of cold acetonitrile with internal standard (4 mg/ml warfarin) was added to each well, followed by addition of NADPH regenerating agent (22.5 μL) and no incubation. For other five time points' plate, NADPH regenerating agent (22.5 μL) was added to each well to initiate the reaction. The plates were incubated at 37° C. for the required time, followed by quenching of the reaction by adding 225 μL of cold acetonitrile with internal standard (4 μg/ml warfarin). All of the plates were sealed and mixed well at 600 rpm for 10 minutes followed by centrifugation at 4000 rpm for 20 minutes. The supernatants (120 μL) were transferred to analytical plates for analysis by LCMS. LCMS conditions were described in the materials and instrumentation section above. The metabolic stability is evaluated via the half-life from least-squares fit of the multiple time points based on first-order kinetics.
10. Minimal Inhibitory Concentration Assay
Minimal inhibitory concentrations (“MICs”) were determined using the microbroth dilution method according to Clinical Laboratory Standards Institute (CLSI; National, C.F. C. L. S., Methods for Dilution Antimicrobial Susceptibility Tests for Bacteria Grow aerobically-Seventh Edition: Approved Standard M7-A7, CLSI, Wayne, Pa., USA, 2008) and were read by visual inspection. Two fold serial dilutions of test compound in 100 μL of the appropriate broth media were first prepared in 96-well round bottom microtiter plates (Nalgene Nunc International, Rochester, N.Y., USA). An equivalent volume (100 μL) of bacterial broth inocula containing approximately 105 bacterial cfu/mL was added to each well to give final concentrations of test compound starting at 200 μM. The plates were then incubated aerobically at 37° C. All strains were incubated overnight. After incubations, in all cases the MIC was recorded as the lowest concentration of drug that prevented bacterial growth. The bacterial strains for which MIC was determined as described in Table 4.
11. Activity of Substituted Urea Depsipeptide Analogs in In Vitro Assays
Substituted urea depsipetide analogs were synthesized as described above. Activity was determined using the assays described above, and the data are shown in Table 3. The EC50 for ClpP activation was determined in the Sa-ClpP in casein -BODIPY assay as described above. The IC50 for ADEP displacement was determined in the ADEP displacement fluorescent polarization assay as described above; and the IC50 for growth inhibition was determined in the Vero cell cytotoxicity assay as described above. The compound number corresponds to the compound numbers used in Tables 1 and 2 and the experimental examples described above.
