Patent ID: 6864282

Claim:
A compound of the formula: wherein the dashed lines represent the presence of a bond, or absence of a bond, wavy lines represent either alpha or beta configuration, solid triangles represent beta configuration and hatched lines represent alpha configuration; n is an integer having the values of 1 to 6; m is an integer having the values of 1 to 8; X is NH 2 , N(R) 2 , NHR, or OR where R is hydrogen, R 4 or a —(CO)R 4 group; Y is ═S or OH, OR 5 or —O(CO)R 5 groups, said OH, OR 5 or O(CO)R 5 groups being attached to the adjacent carbon in alpha or beta configuration; R 1 is H, CH 3 , R 7 , OR 7 or SR 7 where R 7 is an aliphatic, aromatic or heteroaromatic ring, said heteroaromatic ring having 1 to 3 heteroatoms selected from O, S, and N, said aliphatic, aromatic or heteroaromatic ring being optionally substituted with 1 to 3 H 8 groups where H 8 is F, Cl, Br, I, NO 2 , C 1-6 alkyl, C 1-6 fluoro substituted alkyl, COOH, or COOR 9 where R 9 is alkyl of 1 to 6 carbons or CH 2 OCH 3 ; R 2 and R 3 together represent ═O, ═S, or independently are hydrogen or alkyl of 1 to 6 carbon atoms, with the proviso that when X is OR then R 1 is not H nor methyl; R 4 represents (CH 2 ) r OH, (CH 2 ) r OCOR 9 or (CH 2 ) r OR 9 where r is an integer having the values 1 to 6, or R 4 represents saturated or unsaturated acyclic hydrocarbons having from 1 to 20 carbon atoms, or —CH 2 ) q R 6 where q is 0-10 and R 6 is an aliphatic, aromatic or heteroaromatic ring, said heteroaromatic ring having 1 to 3 heteroatoms selected from O, S, and N, said aliphatic, aromatic or heteroaromatic ring being optionally substituted with 1 to R 8 groups where R 8 is F, Cl, Br, I, NO 2 , C 1-6 alkyl, C 1-6 fluoro substituted alkyl, COOH, COOR 9 where R 9 is alkyl of 1 to 6 carbons or CH 2 OCH 3 with the further proviso that when X is NHR, m is 4 and R 1 is methyl then R 4 is not (CH 2 ) 2 OH; R 5 represents saturated or unsaturated acyclic hydrocarbons having from 1 to 20 carbon atoms, or —(CH 2 ) q R 6 , or a pharmaceutically acceptable salt of said compound.
