DT 9605 AU Balagopala MI; Ollapally AP; Lee HJ; Department of Chemistry, Florida A. & M. University, Tallahassee; 32307, USA. SO Cell Mol Biol (Noisy-le-grand). 1995;41 Suppl 1:S1-7. Unique Identifier : AIDSLINE MED/96171628 AB A total of seven steroidal prodrugs of AZT were synthesized and tested in vitro for their anti-HIV activity. Three of them were steroidal carboxylic esters prepared from steroidal 17 beta-carboxylic acids and AZT. The remaining four were alkyl steroidal phospho-triesters of AZT. These prodrugs were synthesized using known procedures. Preliminary results of in vitro anti-HIV activity screening showed that all of these prodrugs were active against HIV. While carboxylic esters showed comparable anti-HIV activity to that of AZT, phosphotriesters were less active than AZT. The therapeutic indices of all these prodrugs are comparable to that of AZT.
