      Lersivirine(UK-453061) is a next-generation non-nucleoside reverse transcriptase inhibitor (NNRTI, IC50=119 nM) with a unique resistance profile that exhibits potent antiretroviral activity against wild-type human immunodeficiency virus and clinically relevant NNRTI-resistant strains.;IC50 value: 0.119 uM [1];Target: NNRTIUK-453061(Compound 5) demonstrated excellent activity against large panels of wild type and drug-resistant HIV consistent with the encouraging profile demonstrated against the isolated RT enzymes. Compound 5 can be readily prepared in multi-gram quantities by virtue of the efficient and concise synthetic route. The compound also has good aqueous solubility and formulation characteristics which enable further in vivo evaluation. Clinical trials evaluating the potential of 5 (UK-453,061, lersivirine) to treat HIV infection are proceeding and further progress will be reported in due course [1].At clinically relevant lersivirine doses (500-1,000 mg total daily dose MedChem Express HY-14267
