Stavudine has the following structural formula:

Stavudine is a nucleoside analogue of thymidine. It is phosphorylated by cellular kinases into active triphosphate. Stavudine triphosphate inhibits the HIV reverse transcriptase by competing with natural substrate, thymidine triphosphate. It also causes termination of viral DNA synthesis by incorporating into it.
