标题:Efficient Discovery Of Potent Anti-Hiv Agents Targeting The Tyr181Cys Variant Of Hiv Reverse Transcriptase
摘要:Non-Nucleoside Reverse Transcriptase Inhibitors (Nnrtis) That Interfere With The Replication Of Human Immunodeficiency Virus (Hiv) Are Being Pursued With Guidance From Molecular Modeling Including Free-Energy Perturbation (Fep) Calculations For Protein Inhibitor Binding Affinities. The Previously Reported Pyrimidinylphenylamine 1 And Its Chloro Analogue 2 Are Potent Anti-Hiv Agents; They Inhibit Replication Of Wild-Type Hiv-1 In Infected Human T-Cells With Ec50 Values Of 2 And 10 Nm,Respectively. However,They Show No Activity Against Viral Strains Containing The Tyr181Cys (Y181C) Mutation In Hiv-Rt. Modeling Indicates That The Problem Is Likely Associated With Extensive Interaction Between The Dimethylallyloxy Substituent And Tyr181. As An Alternative,A Phenoxy Group Is Computed To Be Oriented In A Manner Diminishing The Contact With Tyr181. However,This Replacement Leads To A Roughly 1000-Fold Loss Of Activity For 3 (2.5 Mu M). The Present Report Details The Efficient,Computationally Driven Evolution Of 3 To Novel Nnrtis With Sub-10 Nm Potency Toward Both Wild-Type Hiv-1 And Y181C-Containing Variants. The Critical Contributors Were Fep Substituent Scans For The Phenoxy And Pyrimidine Rings And Recognition Of Potential Benefits Of Addition Of A Cyanovinyl Group To The Phenoxy Ring.
