Stereoselective synthesis and anti-proliferative effects on prostate cancer evaluation of 5-substituted-3,4-diphenylfuran-2-ones
摘要:
Series of 5-substituted-3,4-diphenylfuran-2-ones were stereoselectively prepared. Their potential anti-proliferative effects on prostate cancer and some of their cyclooxygenases (COXs) inhibitory activities were evaluated. Structure activity relationship (SAR) data, acquired by substituent modification at the para-position and ortho-position of the C-3 phenyl ring and 5-substituted modification of the central furanone, showed that 3-(2-chloro-phenyl)-4-(4-methanesulfonyl-phenyl)-5-(1-methoxy-ethyl)-5H-furan-2-one (13p) was the most potent compound and could effectively reduce the proliferation of prostate cancer cells (PC3 cell IC50 = 20 mu M; PD PCDNA cell IC50 = 5 mu M; PD SKP2 cell IC50 = 5 mu M; DU145 cell IC50 = 25 mu M). The cell cycle analysis for 13p in DU145 indicated that 13p may induce G1 phase arrest. (C) 2013 Elsevier Masson SAS. All rights reserved.
A simple and general method has been developed for the synthesis of 3,4-diarylsubstituted maleic anhydride and maleimide through tandem cyclization and oxidation reaction of phenacyl ester or amide. A wide variety of phenacyl esters or amides was treated with DBU under oxygen atmosphere to give the expected compounds in good to excellent yield. Mechanism of the reaction and application of the methodology
