Didanosine (ddl) can be metabolized into dideoxyadenosine triphosphate (ddATP) by series of reaction. Dideoxyadenosine triphosphate can bind and inhibit HIV reverse transcriptase enzyme competitively against natural dATP. Dideoxyadenosine triphosphate will terminate the viral DNA chain to make it missing 3'-OH group so that formation of 5' to 3' phosphodiester could be prevented, which 5' to 3' phosphodiester is required for DNA chain elongation and result in terminated DNA growth.
