The present invention provides a compound having the structure:
wherein
R1a and R1b are independently selected from the group consisting of —H, alkyl, lower-alkyl, substituted alkyl and substituted lower-alkyl;
R2a and R2b are independently selected from the group consisting of —H, lower-alkyl, and substituted lower-alkyl;
R3 is —H, lower-alkyl, substituted lower-alkyl and where R3 and R4 are attached together by a lower-alkyl or a substituted lower-alkyl moiety;
R4 is —H, lower-alkyl, substituted lower-alkyl and where R3 and R4 are attached together form a lower-alkyl or substituted lower-alkyl bridge;
R5, R7, R9 and R11 are independently selected from the group consisting of —H, lower-alkyl, and substituted lower-alkyl;
R6 is —H, lower-alkyl and substituted lower-alkyl;
R8 is —H, lower-alkyl and substituted lower-alkyl;
R10 is —H, lower-alkyl and substituted lower-alkyl;
R12 is —H, lower-alkyl and substituted lower-alkyl; and
A is —C(O)—R13, wherein R13 is —H, —OH, alkyl, lower-alkyl, substituted lower-alkyl or —O(lower-alkyl); —CH2—OR14 wherein R14 is —H, —C(O)CH3, alkyl, lower-alkyl or substituted lower-alkyl; or —CH2—NR15R16, where R15 and R16 are independently selected from —H, lower-alkyl, alkyl, substituted lower-alkyl or substituted alkyl;
a pharmaceutically acceptable salt or derivatives thereof, useful for preventing or treating viral and microbial infections.
