Claim:
A composition comprising a racemate of a compound having the structure wherein Z is O or >N—X, where X is H, straight or branched substituted or unsubstituted alkyl, alkenyl or alkynyl, or acyl, carbamoyl, cycloalkyl, aryl, heterocycloalkyl, heteroaryl, aralkyl, amino, alkyl amino, or dialkyl amino; wherein each of R 1 and R 2 is H or R 1 and R 2 together are ═O; wherein each of R 3 and R 4 is H or R 3 and R 4 together are ═O; wherein each of R 5 and R 6 is, independently, H, alkyl, aralkyl, or aryl; wherein each of R 7 and R 8 is, independently, H, OH or OR 14 , where R 14 is alkyl or —C(O)—R 15 , where R 15 is H, —CH 2 R 16 , —CHR 16 R 16 , —CR 16 R 17 R 16 , —OR 16 , alkenyl or alkynyl, cycloalkyl, aryl, heterocycloalkyl, heteroaryl, aralkyl, amino, alkyl amino, or dialkyl amino, wherein each R 16 is straight or branched, substituted or unsubstituted alkyl, alkenyl or alkynyl, cycloalkyl, aryl, heterocycloalkyl, heteroaryl, aralkyl, or amino; and wherein R 17 is straight or branched, unsubstituted alkyl, alkenyl or alkynyl, cycloalkyl, aryl, heterocycloalkyl, heteroaryl, aralkyl, or amino, or wherein R 7 and R 9 together are >O; wherein each of R 9 and R 10 is, independently, H, alkyl, OH, or OR 13 , where R 13 is an alkyl, an acyl, or an amide, or R 9 and R 10 together are ═CH 2 , or wherein R 8 and R 10 together are >O; wherein if one of R 7 or R 8 and one of R 9 or R 10 is absent, a double bond is formed as indicated by the broken line; and wherein each of R 11 and R 12 is, independently, H, OH, or OR 13 , where R 13 is an alkyl, an acyl, or an amide, or R 11 and R 12 together are ═O, or wherein R 12 and R 10 together are >O.
