摘要:A Series Of Novel Thiazolidin-4-Ones Bearing A Hydrophobic Substituent At 5-Position On The 4,6-Dimethyl-Pyrimidine Ring At N-3 (5C-I And 6C-I) Were Designed On The Prediction Of Qsar Studies,Synthesized In Good Yields Of 60.1-85.3% By Microwave-Assisted One-Pot Protocol With The Combination Of Using Dicyclohexylcarbonimide (Dcc) As The Promotor,And Evaluated As Hiv-1 Reverse Transcriptases Inhibitors. The Results Of In Vitro Hiv-1 Rt Kit Assay Showed That Some Of The New Compounds,Such As 5C,6C,5D,6D,5G,5H And 6I,Could Effectively Inhibit Rt Activity. Among Them,Compounds 5C And 6C Where Ethyl Group Existed At 5-Position On N-3 Pyrimidine Ring Were The Best Ones With The Ic50 Value Of 0.26 Mu M And 0.23 Mu M,Respectively. Structure-Activity Relationship Analysis Of These Analogues Suggested That The Overall Hydrophobicity And Steric Factor Were Important To The Anti-Hiv Rt Activity. The Mechanism Of The Intramolecular Cycloamidation Promoted By Dcc Was Also Investigated With The Key Uncyclized Intermediate 13. (C) 2009 Elsevier Ltd. All Rights Reserved.
