GENERAL DESCRIPTION & APPLICATIONS

Stavudine is a nucleoside analogue of thymidine that inhibits reverse transcriptase and has in vitro activity against human immunodeficiency virus (HIV). It is a white to off-white crystalline powder; melting point 161 - 166 C; soluble in water, sparingly soluble in acetone, slightly soluble in lower alcohol (methanol, ethanol, isopropanol). The chemical designation is (2'-3'-didehydro-2'-3'-dideoxythymidine ( shortly d4T). Reverse transcriptase is an enzyme that  can transcribe RNA into DNA to copy genetic information from RNA to DNA, therefore also called RNA-directed DNA polymerase. Reverse transcriptase inhibitor is an antiretroviral agent that blocks activity of the reverse transcriptase of a retrovirus. Every retrovirus has a reverse transcriptase enzyme which transcribes the genetic information from its RNA into DNA. Protease inhibitors are the second class of antiretroviral drugs for the treatment of HIV.
