MedKoo CAT#: 130179


Description: XZ-259, a strand transfer inhibitor of HIV-1 (HIV-1 integrase inhibitor), was vital in exploring the role of drug resistance mutations (G118R, Q148K) on the viral enzyme integrase (IN) inhibitor selectivity. Unlike raltegravir and elvitegravir, current agents for HIV treatment, XZ-259 was able to successfully inhibit the activity of integrases with the Q148K mutation, demonstrating the potential of XZ-259 as a treatment for HIV-1.
