摘要
Abacavir (1592U89) has recently been approved by the FDA for treatment of HIV infection. Transient kinetic studies were carried out to better understand the interaction of the active metabolite of Abacavir (Carbovir-triphosphate) with wild type and mutant HIV-1 reverse transcriptase. Some of the data is summarized and used as a basis for discussion of inhibition by CBVTP and previously studied nucleoside analogs.
