Compounds where R3 is not hydrogen are one class of preferred compounds. In the article by Corey et al., Proc. Natl. Acad. Sci. USA 1999, 96, 3496-3501, a structure-activity relationship is shown for ecteinascidin-type compounds, indicating that a hydrogen is essential. It is stated on page 3498 that “the protection of the other phenolic hydroxyl group on the E subunit resulted in diminished activity”. We find the hydrogen is not essential, see compounds 96, 97 and 98, among many others.
Compounds wherein R4 is an ester or an ether are among the preferred compounds, for example compounds 57, 60, 61, 63, 65, 68 and 76. In general they have improved toxicology properties and thus give a wider therapeutic window.
In particular, compounds wherein both R3 and R4 are not hydrogen are preferred. Of those, compounds with an ester or ether at these positions are most preferred, and in particular esters and carbonates. See compounds 78, 82, 83, 84, 86, 88, 92. Esters with bulky groups (long aliphatic or aromatic residues) give better results. Examples of particularly preferred substituents include octanoic, palmitic, cinnamoyl, hydrocinnamoyl. See compounds 86, 92. Among the carbonates, terButyloxycarbonyl (tBOC) and vinyloxycarbonyl (VOC) are the most preferred substituents for these positions. See compounds 86 and 92, which are among the best in activity and toxicology. For the ether substituents at these positions, ethyl or a bulky group is preferred.
Compounds with ethyl at R5, N 2′ are preferred, since there is activity at lower concentrations than those at which the compound begins to be toxic.
Compounds with changes at R1 are part of this invention, especially ester groups, R1═R′CO—, with R′ a long aliphatic or aromatic group. See compounds 161, 162, 164, 165, 168, 169, 170, 171, 172, 174, 175. Some of these compounds have substituents at both R1 and R3. They have good activity/toxicity properties. For example 170 is active and in heart and myelo non toxic. Compound 174 is very active (E-10) and toxic at higher concentrations (E-8).
There are compounds that have good ADME properties (absorption-distribution-metabolism-excretion) which are good indicative of pharmacokinetics.
As mentioned above, compounds of the present invention, preferably those with bulky substituted groups, have a good therapeutic window and the estherification of the phenols with different acids and carbonates, results in a general enhancement of the pharmaceutical properties: there is a significant decrease in hepatocyte toxicity, and also a good profile on drug-drug interactions since these derivatives do not show cytochrome inhibition having moreover higher metabolic stability.
In a related aspect of this invention, the compounds have one or more of the following features:
R1 is not acetyl. Preferably it has at least 4, 5 or 6 carbon atoms, for example up to 18 or 24 carbon atoms. Suitable substituents include esters COR′, where R′ is alkyl, alkenyl, often with one or more substituents. Alkyl, substituted alkyl, alkenyl and arylalkenyl are preferred, with suitable substituents including aryl, heterocyclic. Other defintions for R1 include esters of formula COR′ derived from an amino acid, optionally a protected amino acid.
R3 is not hydrogen. Preferably it is R′, COR′ or COOR′ where R′ is a substituent with some bulk. Such bulky substituents include those with branched chain groups, unsaturated groups or cyclic groups including aromatic groups. Thus, branched alkyl, cycloalkyl, branched alkenyl, aryl, heteroaromatic and related groups are preferred for inclusion within the structure of the substituent R3. Preferably the total number of carbon atoms in R3 is 2 to 24, more preferably 6 to 18 carbon atoms. Typically R3 is an ester, ether or carbonate, being of formula COR′, R′ or COOR′.
R4 is not hydrogen. Preferably it is R′, COR′ or COOR′ where R′ is a substituent with some bulk. Such bulky substituents include those with branched chain groups, unsaturated groups or cyclic groups including aromatic groups. Thus, branched alkyl, cycloalkyl, branched alkenyl, aryl, heteroaromatic and related groups are preferred for inclusion within the structure of the substituent R4. Preferably the total number of carbon atoms in R4 is 2 to 24, more preferably 6 to 18 carbon atoms. Typically R4 is an ester, ether or carbonate, being of formula COR′, R′ or COOR′.
Examples of protecting groups for amino and other substituents are given in WO 0069862, and we expressly incorporate that disclosure.
Without being exhaustive, another class of preferred compounds of this invention have one or more of the following definitions:

    X1 is H, —CN or —OH, most especially —OH or —CN.
    X2 is hydrogen.
    X3 is methoxy.
    X4 and X5 are hydrogen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The preferred methods of producing the compounds are described below in schemes I-VI.







Scheme I includes acylation reactions through the different procedures described in the experimental part. Compound 1 corresponds to Et-770. Starting from this compound it is possible to obtain target compounds following acylation methods: A ((RCO)2O/base), B (RCOCl/base), C (RCOOH/DMAP/EDC.HCl) and D (ROCOCl/base). Other acylation reactions have been performed from compound 25 which belongs to the family of the structures of formula I and compound 47 whose structure is described further.
Compounds 29, 30, 31, 32 and 33 are compounds wherein R1, R2 and R3 is a vinyl radical or an hydrogen atom.




In Scheme II method E involves reactions of alkylation (RBr/Cs2CO3) and method G (RCHO/NaBCNBH3/AcOH) is the reductive alkylation at N-2′. Compounds 34, 35 and 36 are obtained when the alkylation reaction is performed with MeI. With these methodologies we generate N and O-alkyl derivatives starting from compound 1. In compound 53 a phosphate group is introduced at position C-6′ using dibenzyl phosphite.







Scheme III includes hydrolysis of tert-butylcarbonate in C-6′ through method F (TFA/H2O/CH2Cl2) and hydrolysis of acetyl groups in C-5 from compound 42 with KOH/H2)/THF and in C-6′ from compound 6 with TEA/MeOH/THF. Also is described the formation of compound 52 starting from compound 1 through an oxidation reaction of the right aromatic ring.







The different analogs of Et-743 wherein R1, R2 and R3 are acyl, carbonate, carbamate or alkyl groups are prepared following method H (AgNO3/CH3CN/H2O) or I (CuBr/THF/H2O) from the derivatives of Et-770 (Scheme IV). In both cases the reaction involves the transformation of the nitrile group in C-21 into the hydroxyl group. Other specific derivatives as compounds 96, 97, 98, 99, 100, 101 and 102 are synthetised from their corresponding analogs of Et-770, compounds 51, 47, 36, 31, 32, 52 and 48 following the same methodology.







In Scheme V the starting material is compound 106 obtained from compound 4 by hydrolysis of the acetyl group in C-5 with KOH/THF/H2O. From compound 106 and by esterification and alkylation reactions can be prepared derivatives with structures of formula I. The next step includes the hydrolysis of the tert-butylcarbonate group (method F: TFA/H2O/CH2Cl2 or method J: TMSCl, NaI; CH3CN/H2O) to afford derivatives of structures of formula III which are transformed into the final compounds (structure of formula IV) by conversion of the nitrile group in C-21 into the hydroxyl group. This last step is achieved following method H (AgNO3/CH3CN/H2O), method I (CuBr/THF/H2O) or method K (CuCl/THF/H2O). In the case of derivatives of structure of formula I wherein R1 and R2 are Boc, R1 are Boc, AlaBoc and Voc radicals the hydrolysis of the tert-butylcarbonyl involves also the hydrolysis of these ester functionalities. These compounds are transformed into the final analogs through method H.













From Et-729 it is possible to obtain target compounds through different experimental conditions. In the attempts to prepare compound 186, other two compounds (184 and 185) were isolated as it is described in the scheme VI. Treatment of compound 186 with Alloc chloroformiate, pyridine and DMAP affords compound 187. With Boc anhydride with o without DIPEA we are able to obtain Boc derivatives (compounds 188, 189 and 190). From compound 190 through an alkylation reaction (Cs2CO3, allyl bromide) is prepared compound 199 which is transformed into compound 201 by hydrolysis of tert-butyl carbonate groups following method F.
From the key compound 188 through esterification reactions it is possible to generate compounds of structure of formula I mono or di substituted. Hydrolysis of tert-butyl carbonate group (method F) and transformation of the nitrile group in C-21 into the hydroxyl group (method H) lead to the compounds of structure of formula III. Also from compound 188 by a reductive methylation it is obtained compound 200 with a methyl group in position N-2′. Hydrolysis of the amide bond (method F) and conversion of the nitrile group into the hydroxyl group (method H) affords compound 217.







In this scheme compound 221 can be obtained from compound 218, described in the Patent WO 01/77115 A1 as compound 24, following a transamination reaction to afford 219 and a Pictect-Spengler cyclization to give compound 220. Final step is the conversion of nitrile group into OH in C-21 with the usual methodology (method K) using AgNO3. Also compound 224 can be obtained from compound 222, described in the WO 00/69862 as compound 36, following a Pictect-Splenger cyclization to give compound 223. Final step is the conversion of nitrile group into OH in C-21 with the usual methodology (method K)

1°. Inhibition of Cell Growth by Counting Cells.

This form of the assay employs 24 well multidishes of 16 mm diameter (Bergeron, 1984; Schroeder, 1981). The tumor cell lines employed are: P-388 (ATCC CCL 46), suspension culture of a lymphoid neoplasm from a DBA/2 mouse; A-549 (ATCC CCL 185), monolayer culture of a human lung carcinoma; HT-29 (ATCC HTB-38), monolayer culture of a human colon carcinoma; MEL-28 (ATCC HTB-72), monolayer culture of a human melanoma and DU-145 (ATCC HTB-81), monolayer culture of a human prostate carcinoma.
Cells were maintained, in logarithmic phase of growth in Eagle's Minimum Essential Medium, with Earle's Balanced Salts, with non-essential amino acids, with 2.0 mM L-Glutamine, without sodium bicarbonate (EMEM/neaa), supplemented with 10% Fetal Calf Serum (FCS), 10−2 M. sodium bicarbonate and 0.1 U/l penicillin G+0.1 g/l streptomycin sulfate. For the experiments, cells are harvested from subconfluent cultures using trypsin and resuspended in fresh medium before plating.
P-388 cells were seeded into 16 mm diameter wells at 1×104 cells per well in 1 ml aliquots of EMEM 5% FCS containing different concentrations of the sample to be tested. A separate set of cultures without drug was seeded as control of growth, to ensure that cells remained in exponential phase of growth. All determinations are carrying out in duplicate. After three days of incubation at 37° C., 5% CO2 in a 98% humid atmosphere, an approximately IC50 was determined by comparing the growth in wells with drug to the growth in wells control.
A-549, HT-29, MEL-28 and DU-145 cells were seeded into 16 mm diameter wells at 1×104 cells per well in 1 ml aliquots of EMEM 5% FCS containing different concentrations of the sample to be tested. A separate set of cultures without drug was seeded as control of growth, to ensure that cells remained in exponential phase of growth. All determinations are carrying out in duplicate. After three days of incubation at 37° C., 5% CO2 in a 98% humid atmosphere cells were stained with 0.1% crystal violet. An approximately IC50 was determined by comparing the growth in wells with drug to the growth in wells control.
For quantifying the activity, after the incubation time, cells are trypsinized and counted in a Coulter Counter ZM. All counts (net cells per well), represent the average of duplicate wells. % G, percent of growth relative to cultures without drug. The results of these assays are used to generate dose-response curves from which more precise IC50 values are determined (sample concentration which produces 50% cell growth inhibition).
Obtained results may predict the usefulness of a certain drug as a potential cancer treatment. For this technique, compounds which show IC50 values smaller than 1 μg/ml are selected to continue with further studies. IC50's data allow to predict that not only could a drug be cystostatic, but also it could have a potential in terms of tumor reduction.
2°. Inhibition of Cells Growth by Colorimetric Assay.
A colorimetric type of assay, using sulforhodamine B (SRB) reaction has been adapted for a quantitative measurement of cell growth and viability [following the technique described by Philip Skehan, et al. (1990), New colorimetric cytotoxicity assay for anticancer drug screening, J. Natl. Cancer Inst., 82:1107-1112]
This form of the assay employs 96 well cell culture microplates of 9 mm diameter (Faircloth, 1988; Mosmann, 1983). Most of the cell lines are obtained from American Type Culture Collection (ATCC) derived from different human cancer types.
Cells are maintained in RPMI 1640 10% FBS, supplemented with 0.1 g/l penicillin and 0.1 g/l streptomycin sulfate and then incubated at 37° C., 5% CO2 and 98% humidity. For the experiments, cells were harvested from subconfluent cultures using trypsin and resuspended in fresh medium before plating.
Cells are seeded in 96 well microtiter plates, at 5×103 cells per well in aliquots of 195 μl medium, and they are allowed to attach to the plate surface by growing in drug free medium for 18 hours. Afterward, samples are added in aliquots of 5 μl in a ranging from 10 to 10−8 μg/ml, dissolved in DMSO/EtOH/PBS (0.5:0.5:99). After 48 hours exposure, the antitumor effect are measured by the SRB methodology: cells are fixed by adding 50 μl of cold 50% (wt/vol) trichloroacetic acid (TCA) and incubating for 60 minutes at 4° C. Plates are washed with deionized water and dried. One hundred μl of SRB solution (0.4% wt/vol in 1% acetic acid) is added to each microtiter well and incubated for 10 minutes at room temperature. Unbound SRB is removed by washing with 1% acetic acid. Plates are air dried and bound stain is solubilized with Tris buffer. Optical densities are read on a automated spectrophotometric plate reader at a single wavelength of 490 nm.
The values for mean+/−SD of data from triplicate wells are calculated. Some parameters for cellular responses can be calculated: GI═growth inhibition, TGI═total growth inhibition (cytostatic effect) and LC═cell killing (cytotoxic effect).
Obtained results may predict the usefulness of a certain drug as a potential cancer treatment. For this technique, compounds which show GI50 values smaller than 10 μg/ml are selected to continue with further studies. GI50's data allow to predict that not only could a drug be cystostatic, but also it could have a potential in terms of tumor reduction.
