 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.
