Application

 

Stavudine is a nucleoside analog of thymidine that inhibits reverse transcriptase and has an 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, , slightly soluble in lower alcohols. The chemical name is (2'-3'-didehydro-2'-3'-dideoxythymidine (d4T). Reverse transcriptase is a method in which RNA can be transcribed into DNA to replicate genetic information from RNA to DNA. The enzyme, therefore also known as the RNA-reverse transcriptase inhibitor, is an antiretroviral drug that blocks the activity of retroviral reverse transcriptase. Each retrovirus has a reverse transcriptase that can be inherited. Information is transcribed from RNA into DNA. Protease inhibitors are the second class of antiretroviral drugs.
