标题:Novel Non-Nucleoside Inhibitors Of Human Immunodeficiency Virus Type 1 (Hiv-1) Reverse Transcriptase. 4. 2-Substituted Dipyridodiazepinones As Potent Inhibitors Of Both Wild-Type And Cysteine-181 Hiv-1 Reverse Transcriptase Enzymes
摘要:The Major Cause Of Viral Resistance To The Potent Human Immunodeficiency Virus Type 1 Reverse Transcriptase (Rt) Inhibitor Nevirapine Is The Mutation Substituting Cysteine For Tyrosine-181 In Rt (Y181C Rt),An Evaluation,Against Y181C Rt,Of Previously Described Analogs Of Nevirapine Revealed That The 2-Chlorodipyridodiazepinone 16 Is An Effective Inhibitor Of This Mutant Enzyme. The Detailed Examination Of The Structure-Activity Relationship Of 2-Substituted Dipyridodiazepinones Presented Below Shows That Combined Activity Against The Wildtype And Y181C Enzymes Is Achieved With Aryl Substituents At The 2-Position Of The Tricyclic Ring System. In Addition,The Substitution Pattern At C-4,N-5,And N-11 Of The Dipyridodiazepinone Ring System Optimum For Inhibition Of Both Wild-Type And Y181C Rt Is No Longer The 4-Methyl-11-Cyclopropyl Substitution Preferred Against The Wild-Type Enzyme But Rather The 5-Methyl-11-Ethyl (Or 11-Cyclopropyl) Pattern. The More Potent 8-Substituted Dipyridodiazepinones Were Evaluated Against Mutant Rt Enzymes (L100I Rt,K103N Rt,P236L Rt,And E138K Rt) That Confer Resistance To Other Non-Nucleoside Rt Inhibitors,And Compounds 42,62,And 67,With Pyrrolyl,Aminophenyl,And Aminopyridyl Substituents,Respectively,At The 2-Position,Were Found To Be Effective Inhibitors Of These Mutant Enzymes Also.
