Patent ID: 7612045

Claim:
A compound corresponding to the following chemical structure: wherein: R 1 is selected from the group consisting of hydrogen, hydroxyl, halide, methoxy, acetoxy, —CH 2 OH, —CH 2 CH 2 OH, —CN, —C 1-2 (halo)alkyl, —CH 2 Cl, —C(O)H, —C(O)NH 2 , —SH, CF 3 , CCl 3 , and —NAA, wherein each A is independently selected from the group consisting of H and C 1 -C 2 alkyl; R 2 is selected from the group consisting of hydroxyl, halide, —CN, —C(O)NH 2 , —SH, —S(O)NH 2 , CF 3 , CCl 3 , —NYY wherein each Y is independently selected from H and C 1 -C 5 alkyl, C 1-5 acyl halides, —C 1-5 (halo)alkyl, C 1-5 acyl residues, C 2-5 secondary amides, (C 1-5 )(C 1-5 )tertiary amides, C 1-5 alcohols, C 1-5 substituted alkyls, C 2-5 alkenyls, C 2-5 substituted alkenyls, —OC(O)—OC(CH 3 ) 3 , —OC(O)—CH═CH-phenyl, —OC(O)—R, wherein R is an unbranched or branched C 1 -C 5 alkyl, and —OC(O)C 1-5 R 5 R 6 wherein R 5 is an alkylene or alkenylene of up to 5 carbons and R 6 is selected from the group consisting of substituted and unsubstituted C 5-7 aromatics, substituted and unsubstituted C 5-7 cycloalkyls, and substituted and unsubstituted C 5-7 heterocycloalkyls; provided that: i) R 2 is not hydroxyl when R 1 is hydrogen, hydroxyl, methoxy, chloride or —CN; ii) R 2 is not chloride or —OC(O)CH 3 when R 1 is hydrogen; iii) R 2 is not —OC(O)—CH═CH-(m-hydroxy, p-methoxy-phenyl) or —OC(O)—CH═CH-(p-hydroxy-phenyl) when R 1 is hydroxyl; and iv) R 2 is not C 1-5 substituted alkyl, —C 1-5 (halo)alkyl, or C 1-5 , alcohol when R 1 is hydrogen, halide, hydroxyl, methoxy, acetoxy or —SH; one of R 3 and R 4 is hydrogen and the other is methyl; and R 1 is in the β stereochemical configuration and R 2 is in the α stereochemical configuration; and salts, hydrates, solvates, prodrugs and N-oxides thereof.
