Description: NOVEL GUANIDINOBENZAMIDES Field of the Invention This invention relates to melanocortin-4 receptor (MC4-R) agonists and methods of their preparation. The invention also relates to methods of treating melanocortin-4 receptor-mediated diseases, such as obesity or diabetes, by activating the melanocortin-4 receptor with compounds provided herein. Background of the Invention Melanocortins are peptide products resulting from post- translational processing of pro-opiomelanocortin and are known to have a broad array of physiological activities. The natural melanocortins include the different types of melanocyte stimulating hormone (α-MSH, β-MSH, γ-MSH) and ACTH. Of these, α-MSH and ACTH are considered to be the main endogenous melanocortins. The melanocortins mediate their effects through melanocortin receptors (MC-Rs), a subfamily of G-protein coupled receptors. There are at least five different receptor subtypes (MC1-R to MC5-R). MC1-R mediates pigmentation of the hair and skin. MC2-R mediates the effects of ACTH on steroidogenesis in the adrenal gland. MC3-R and MC4-R are predominantly expressed in the brain. MC5-R is considered to have a role in the exocrine gland system. The melanocortin-4 receptor (MC4-R) is a seven- transmembrane receptor. MC4-R may participate in modulating the flow of visual and sensory information, coordinate aspects of somatomotor control, and/or participate in the modulation of autonomic outflow to the heart. K. G. Mountjoy et a , Science, 257:1248-125 (1992). Significantly, inactivation of this receptor by gene targeting has resulted in mice that develop a maturity onset obesity syndrome associated with hyperphagia, hyperinsulinemia, and hyperglycemia. D. Husznar et al., Cell, 88(1): 131-41 (1997). MC4-R has also been implicated in other disease states including erectile disorders, cardiovascular disorders, neuronal injuries or disorders, inflammation, fever, cognitive disorders, and sexual behavior disorders. M. E. Hadley and C. Haskell-Luevano, The proopiomelanocortin system, Ann. N. Y. Acad. Sci., 885:1 (1999). Furthermore, observations in connection with endogenous MCx- R antagonists indicate that MC4-R is implicated in endogenous energy regulation. For example, an agouti protein is normally expressed in the skin and is an antagonist of the cutaneous MC receptor involved in pigmentation, MC1-R. M. M. Ollmann ef al, Science, 278:135-138 (1997). However, overexpression of agouti protein in mice leads to a yellow coat color due to antagonism of MC1 -R and increased food intake and body weight due to antagonism of MC4-R. L. L. Kiefer et al., Biochemistry, 36: 2084-2090 (1997); D. S. Lu et a , Nature, 371 :799-802 (1994). Agouti related protein (AGRP), an agouti protein homologue, antagonizes MC4-R but not MC1-R. T. M. Fong et al, Biochem. Biophys. Res. Commun. 237:629-631 (1997). Administration of AGRP in mice increases food intake and causes obesity but does not alter pigmentation. M. Rossi et al, Endocrinology, 1*39:4428-4431 (1998). Together, this research indicates that MC4-R participates in energy regulation, and therefore, identifies this receptor as a target for a rational drug design for the treatment of obesity. In connection with MC4-R and its uncovered role in the etiology of obesity and food intake, the prior art includes reports of compounds and compositions that act as agonists or antagonists of MC4-R. As examples, U.S. Patent No. 6,060,589 describes polypeptides that are capable of modulating signaling activity of melanocortin receptors. Also, U.S. Patent Nos. 6,054,556 and 5,731 ,408 describe families of agonists and antagonists for MC4-R receptors that are lactam heptapeptides having a cyclic structure. WO 01/10842 discloses MC4-R binding compounds having a multitude of structures and methods of using such compounds to treat MC4-R associated disorders. Some of the compounds described include amidino- and guanidino- containing arenes and heteroarenes. Other guanidine-containing compounds having a variety of biological activities are also known in the prior art. For example, U.S. patent No. 4,732,916 issued to Satoh et al. discloses guanidine compounds useful as antiulcer agents; U.S. Patent No. 4,874,864, U.S. Patent No. 4,949,891 , and U.S. Patent No. 4,948,901 issued to Schnur et al. and EP 0343 894 disclose guanidino compounds useful as protease inhibitors and as anti- plasmin and anti-thrombin agents; and U.S. Patent No. 5,352,704 issued to Okuyama et al. discloses a guanidino compound useful as an antiviral agent. Guanidine-containing compounds are also disclosed in other references. For example, U.S. Patent No. 6,030,985 issued to Gentile et al. discloses guanidine compounds useful for treating and preventing conditions in which inhibition of nitric oxide synthetase is beneficial such as stroke, schizophrenia, anxiety, and pain. U.S. Patent No. 5,952,381 issued to Chen et al. discloses certain guanidine compounds for use in selectively inhibiting or antagonizing α v β 3 integrins. Various 5-, 6-, and 7- membered fully saturated 1- azacarbocyclic-2-ylidene derivatives of guanidine are disclosed as having anti-secretory and hypoglycemic activities by U.S. Patent No. 4,211 ,867 issued to Rasmussen. Such compounds are also taught as useful for the treatment of cardiovascular disease. Other guanidine derivatives are disclosed by U.S. Patent No. 5,885,985 issued to Macdonald et al. as useful in therapy to treat inflammation. Nevertheless, there remains a need for potent and specific agonists of MC4-R that are low molecular weight non-peptide small molecules. Methods of treating a melanocortin-4 receptor mediated disease, such as obesity, with such non-peptide drugs, are also particularly desirable.

Detailed Description of the Preferred Embodiment The instant invention relates to novel classes of small molecule melanocortin-4 receptor (MC4-R) agonists. These compounds can be formulated into compositions and are useful in activating MC4-R, or in the treatment of MC4-R-mediated diseases, such as obesity, type II diabetes, erectile dysfunction, polycystic ovary disease, complications resulting from or associated with obesity and diabetes, and Syndrome X. The following definitions are used throughout this specification. Alkyl groups include straight chain and branched alkyl groups having 1 to about 8 carbon atoms. Examples of straight chain alkyl groups include methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, and octyl groups.

Although the phrase "aryl groups" includes groups containing fused rings, such as fused aromatic-aliphatic ring systems, it does not include aryl groups that have other groups, such as alkyl or halo groups, bonded to one of the ring members. Rather, groups such as tolyl are referred to as substituted aryl groups. The phrase "aryl groups" includes groups bonded to one or more carbon atom(s), and/or nitrogen atom(s), in the compounds of formulas I and II. Representative substituted aryl groups may be mono-substituted or substituted more than once, such as, but not limited to, 2-, 3-, 4-, 5-, or 6-substituted phenyl or benzyl groups, which may be substituted with groups including, but not limited to, amino, alkoxy, alkyl, or halo.

Heterocyclyl groups are nonaromatic ring compounds containing 3 or more ring members, of which, one or more is a heteroatom such as, but not limited to, N, O, and S. The phrase "heterocyclyl group" includes fused ring species including those comprising fused aromatic and nonaromatic groups. The phrase also includes polycyclic ring systems containing a heteroatom such as, but not limited to quinuclidyl. However, the phrase does not include heterocyclyl groups that have other groups, such as alkyl or halo groups, bonded to one of the ring members. Rather, these are referred to as "substituted heterocyclyl groups". Heterocyclyl groups include, but are not limited to, piperazino, morpholino, thiomorpholino, pyrrolidino, piperidino and homopiperazino groups. Representative substituted heterocyclyl groups may be mono-substituted or substituted more than once, such as, but not limited to morpholino or piperazino groups, which are 2-, 3-, 4-, 5-, or 6-substituted, or disubstituted with groups including, but not limited to, amino, alkoxy, alkyl, or halo. Heteroaryl groups are aromatic ring compounds containing 3 or more ring members, of which, one or more is a heteroatom such as, but not limited to, N, O, and S.

Rather, heteroaryl groups with such substitution are referred to as "substituted heteroaryl groups". Representative substituted heteroaryl groups may be substituted one or more times with groups including, but not limited to, amino, alkoxy, alkyl, or halo. Heterocyclylalkyl groups are alkyl groups as defined above in which a hydrogen or carbon bond of an alkyl group is replaced with a bond to a heterocyclyl group as defined above. Heteroarylalkyl groups are alkyl groups as defined above in which a hydrogen or carbon bond of an alkyl group is replaced with a bond to a heteroaryl group as defined above. Aminocarbonyl groups are groups of the formula RR'NC(O)-, wherein R or R' may be the same or different, and each is independently selected from H, or substituted or unsubstituted alkyl, cycloalkyl, aryl, heterocyclyl or heteroaryl groups, as defined above. In general, "substituted" refers to a group as defined above in which one or more bonds to a hydrogen atom contained therein are replaced by a bond to non-hydrogen or non-carbon atoms such as, but not limited to, a halogen atom such as F, Cl, Br, and I; an oxygen atom in groups such as hydroxyl groups, alkoxy groups, aryloxy groups, and ester groups; a sulfur atom in groups such as thiol groups, alkyl and aryl sulfide groups, sulfone groups, sulfonyl groups, and sulfoxide groups; a nitrogen atom in groups such as amines, amides, alkylamines, dialkylamines, arylamines, alkylarylamines, diarylamines, N-oxides, imides, and enamines; a silicon atom in groups such as in trialkylsilyl groups, dialkylarylsilyl groups, alkyldiarylsilyl groups, and triarylsilyl groups; and other heteroatoms in various other groups.

A therapeutically effective dose refers to that amount of the compound that results in amelioration of symptoms. Specific dosages may be adjusted depending on conditions of disease, the age, body weight, general health conditions, sex, diet of the subject, dose intervals, administration routes, excretion rate, and combinations of drugs. Any of the above dosage forms containing effective amounts are well within the bounds of routine experimentation and therefore, well within the scope of the instant invention. A therapeutically effective dose may vary depending upon the route of administration and dosage form. The preferred compound or compounds of the instant invention is a formulation that exhibits a high therapeutic index. The therapeutic index is the dose ratio between toxic and therapeutic effects which can be expressed as the ratio between LD 50 and EDso- The LD 50 is the dose lethal to 50% of the population and the ED 50 is the dose therapeutically effective in 50% of the population. The LD 50 and ED 5 o are determined by standard pharmaceutical procedures in animal cell cultures or experimental animals. The present invention also provides methods of enhancing MC4-R activity in a human or non-human animal. The method comprises administering an effective amount of a compound, or composition, of the instant invention to said mammal or non-human animal. Effective amounts of the compounds of the instant invention include those amounts that activate MC4-R which are detectable, for example, by an assay described below in the illustrative Examples, or any other assay known by those skilled in the art that a detect signal transduction, in a biochemical pathway, through activation of G-protein coupled receptors, for example, by measuring an elevated cAMP level as compared to a control model. Accordingly, "activating" means the ability of a compound to initiate a detectable signal. Effective amounts may also include those amounts which alleviate symptoms of a MC4-R disorder treatable by activating MC4-R. An MC4-R disorder, or MC4-R-mediated disease, which may be treated by those methods provided, include any biological disorder or disease in which MC4-R is implicated, or which inhibition of MC4-R potentiates a biochemical pathway that is defective in the disorder or disease state. Examples of such diseases are obesity, erectile disorders, cardiovascular disorders, neuronal injuries or disorders, inflammation, fever, cognitive disorders, type II diabetes, polycystic ovary disease, Syndrome X, complications from obesity and diabetes, and sexual behavior disorders. In a preferred embodiment, the instant invention provides compounds, compositions, and methods effective for reducing energy intake and body weight; reducing serum insulin and glucose levels; alleviating insulin resistance; and reducing serum levels of free fatty acids. Accordingly, the instant invention is particularly effective in treating those disorders or diseases associated with obesity or type II diabetes. "Treating" within the context of the instant invention, therefore, means an alleviation of symptoms associated with a disorder or disease, or halt of further progression or worsening of those symptoms, or prevention or prophylaxis of the disease or disorder. For example, within the context of obesity, successful treatment may include an alleviation of symptoms or halting the progression of the disease, as measured by reduction in body weight, or a reduction in amount of food or energy intake. In this same vein, successful treatment of type I or type II diabetes may include an alleviation of symptoms or halting the progression of the disease, as measured by a decrease in serum glucose or insulin levels in, for example, hyperinsulinemic or hyperglycemic patients. The present invention, thus generally described, will be understood more readily by reference to the following examples, which are provided by way of illustration and are not intended to be limiting of the present invention.

The reaction was then washed with 10% citric acid, 10% sodium carbonate, and brine before being dried over sodium sulfate. The organic solvent was then removed under reduced pressure to leave a brown oil. This crude material was then purified via flash chromatography using 100% DCM running solvent to recover the product sulfonamide. (MH+) 306.1. Step 2. The Sulfonamide (1 equivalent) was dissolved in acetone and stirred in a round-bottomed flask with K 2 CO 3 (6.9 equivalents). This was warmed to 78°C and refluxed, ethyl bromoacetate (1.5 equivalents) was then added, and the reaction was allowed to proceed overnight. The K 2 C0 3 was then filtered off and the solvent removed under reduced pressure.

Example 120 In Vivo Studies of MC4-R Agonists on Energy Intake, Body Weight, Hyperinsulinemia, and Glucose Levels. In vivo studies were conducted to observe the effect of MCR-4 agonists on energy intake, body weight, hyperinsulinemia, and glucose levels. All studies were conducted with male 9-10 week old ob/ob mice which display early onset of obesity, insulin resistance and diabetes due to leptin deficiency. Mice were acclimated in the facility for 1 week before studies and are caged individually. Vehicle-treated (control) and drug treated mice studies were always run in parallel. In multi-day studies, mice (8-15 per group) were monitored for baseline body weight, fasting levels of glucose, insulin, blood lipids and energy expenditure and then injected twice daily (9 a.m. and 5 p.m.) with 3 mg/kg of the MC4-R agonist 4-[(N-cyclohexyl-3,5-dimethyl-piperazine- 1 -carboximidoyl)-amino]-N-[2-(2,4-dichlorophenyl)-ethyl]-benzamide for 4 weeks. Body weight as well as food and water intake were monitored daily. Animals were fasted overnight for measurements of fasting levels of glucose, insulin, and lipids once a week until the end of the study. Energy expenditure (resting metabolic rate, i.e., O2 consumption and CO2 production) were monitored in air tight chambers at the end of the study on fed animals. O 2 consumption and CO2 production were measured using Oxymax systems (Columbus Instruments). Oral glucose tolerance test (OGTT - a routine test for diabetes and glucose intolerance) was performed on overnight fasted mice at the end of the study. Blood glucose and oral glucose tolerance were measured using a glucose monitor (Onetouch sold by Lifescan). Free fatty acids were measured using an non-esterified free fatty acids enzymatic assay (Waco Chemicals). Serum Insulin levels were measured by immunoassay (Alpco). Results The effect of 4-[(N-cyclohexyl-3,5-dimethyl-piperazine-1- carboximidoyl)-amino]-N-[2-(2,4-dichlorophenyl)-ethyl]-benzamide on food intake is shown in Figure 1. Figure 1 shows total food intake as represented as grams/mouse/day throughout the 4 week study. Food is monitored every morning. Cumulative food intake represents the total amount of grams the mice consumed during the study. Each group (vehicle or drug ) had 15 mice. As shown in Figure 1 , a significant reduction in food intake was demonstrated in those mice treated IP with 4-[(N-cyclohexyl-3,5-dimethyl-piperazine-1- carboximidoyl)-amino]-N-[2-(2,4-dichloro-phenyl)-ethyl]-benzamide for 4 weeks. The effect of 4-[(N-cyclohexyl-3,5-dimethyl-piperazine-1- carboximidoyl)-amino]-N-[2-(2,4-dichlorophenyl)-ethyl]-benzamide on body weight is shown in Figure 2. Figure 2 shows body weight reduction as represented as grams/mouse throughout the 4 weeks of the study. Mice were weighed every morning. At the end of the study, drug treated mice weighed 19% less than the vehicle treated mice. Each group (vehicle or drug) had 15 mice. As shown in Figure 2, significant body weight reduction was demonstrated in those mice treated IP with 4-[(N-cyclohexyl-3,5-dimethyl- piperazine-1-carboximidoyl)-amino]-N-[2-(2,4-dichlorophenyl)-ethyl]- benzamide for 4 weeks. The effect of 4-[(N-cyclohexyl-3,5-dimethyl-piperazine-1- carboximidoyl)-amino]-N-[2-(2,4-dichlorophenyl)-ethyl]-benzamide on blood glucose levels in shown in Figure 3. Figure 3 shows blood glucose levels as represented as mg of glucose/dl of blood. Mice were fasted overnight and glucose levels were measured at 8 a.m. the following morning. Vehicle treated mice showed an increase in blood glucose consistent with the rapid progression of diabetes in this mouse strain whereas, diabetes was slowed down considerably (47% decrease) in drug treated mice. Each group (vehicle or drug) had 8 mice. As shown in Figure 3, a significant reduction in fasting glucose levels were demonstrated in those mice treated IP with 4-[(N- cyclohexyl-3,5-dimethyl-piperazine-1-carboximidoyl)-amino]-N-[2-(2,4- dichlorophenyl)-ethyl]-benzamide for 4 weeks. The effect of 4-[(N-cyclohexyl-3,5-dimethyl-piperazine-1 - carboximidoyl)-amino]-N-[2-(2,4-dichlorophenyl)-ethyl]-benzamide on glucose levels during oral glucose tolerance test (OGTT) is shown in Figure 4. Figure 4 shows OGTT as performed on overnight fasted mice at the end of the study. Blood glucose is represented as mg of glucose/dl of blood. Glucose levels were measured the following morning: 90 minutes before and 25, 60 and 120 minutes after an oral glucose load (2 mg/kg). Orally administered glucose quickly elevated blood glucose, similar to a meal, and the response to this exogenous glucose gave a measure of how well the body regulated glucose homeostasis. As shown in Figure 4, vehicle treated mice showed an elevated response to glucose consistent with their diabetic state, whereas drug treated mice showed a very much improved glucose disposal, illustrated as a 45% decrease of the area under the curve. Each group (vehicle or drug) had 15 mice. The effect of 4-[(N-cyclohexyl-3,5-dimethyl-piperazine-1- carboximidoyl)-amino]-N-[2-(2,4-dichlorophenyl)-ethyl]-benzamide on free fatty acid (FFA) levels is shown in Figure 5. Figure 5 shows FFA represented as mmoles of FFA/L of serum. Mice were fasted overnight and free fatty acid levels were measured at 8 a.m. the following morning. As shown in Figure 5, vehicle treated mice showed elevated levels of FFA throughout the study consistent with their obese state, whereas the drug treated mice diabetes showed a dramatic 50% decrease. Each group (vehicle or drug ) had 8 mice. The effect of 4-[(N-cyclohexyl-3,5-dimethyl-piperazine-1- carboximidoyl)-amino]-N-[2-(2,4-dichlorophenyl)-ethyl]-benzamide on serum insulin levels is shown in Figure 6. Serum insulin levels were measured one hour after single IP dosing of I and 3 mg/kg in overnight fasted ob/ob mice. In Figure 6, serum insulin levels are represented as ng of insulin/ml of serum. As shown in Figure 6, drug treated mice showed a dose dependent decrease of 27% and 55% respectively relative to vehicle. Each group (vehicle, or drug ) had 6 mice.
