摘要:Novel Substituted Benzoyl Benzoic Acids And Phenylacetic Acids 1-14 Have Been Synthesized And Evaluated For Inhibition Of Rat And Human Steroid 5 Alpha-Reductase Isozymes I And 2. The Compounds Turned Out To Be Potent And Selective Human Type 2 Enzyme Inhibitors,Exhibiting Ic50 Values In The Nanomolar Range. The Phenylacetic Acid Derivatives Were More Potent Than The Analogous Benzoic Acids. Bromination In The 4-Position Of The Phenoxy Moiety Led To The Strongest Inhibitor In This Class (12; Ic50 = 5 Nm),Which Was Equipotent To Finasteride. Since Oral Absorption Is Essential For A Potential Drug,12 Was Further Examined. In The Parallel Artificial Membrane Permeation Assay (Pampa) It Turned Out To Be A Good Permeator,Whereas It Was A Medium Permeator In Caco2 Cells. After Oral Administration (40 Mg/kg) To Rats A High Bioavailability And A Biological Half-Life Of 5.5 H Were Observed,Making It A Promising Candidate For Clinical Evaluation.
