  Synthesis and antiulcer activity of novel 5-(2-ethenyl substituted)-3(2H)-furanones

  摘要：

  In order to investigate new antiulcer agents, spizofurone 1 (AG-629) was fragmented and reassembled to generate 5-phenyl-2,2-dimethyl-3(2H)-furanone (bullatenone, 2). Because of the antiulcer activity of 2,5-phenyl-substituted 2,2-dimethyl-3(2H)-furanones (3-6) were made and shown to have poor activity. Insertion of an ethenyl link between the furanone and phenyl rings gave 5-(2-phenylethenyl)-2,2-dimethyl-3(2H)-furanone (7). This compound had better activity than 2. Compounds 8-41 were synthesized to evaluate the SAR in 5-(2-ethenyl substituted)-3(2H)-furanones. Electron-withdrawing substituents on the aromatic ring (8, 10, 19, and 20) gave 2-3-fold higher activity. Further increases in the activity were found when the phenyl ring was replaced by heterocyclic nuclei. Compounds that contained a thiophene (29), pyridine (24-26), or quinoline ring (32) had the best activity. Replacement of the methyl group on the furanone ring with a phenyl (34) or p-fluorophenyl (40) substituent in the 2-pyridine series gave compounds with activity that ranked with the best obtained in this study. The best compounds from the above SAR studies were evaluated in the ethanol-necrosis model for duration of cytoprotection action. Compounds 19, 24, and 29, which had the best duration of action, were tested with AG-629 in the acidified aspirin and indomethacin-induced lesion models. Only compound 24 had equivalent activity with AG-629 in both models.

• New 5-(2-ethenylsubstituted)-3(2H)-furanones with in vitro antiproliferative activity

  DOI：10.1016/s0040-4020(03)00776-2

  日期：2003.7

  A convenient route to new 3(2H)-furanones is described through hydrogenolysis and subsequent acidic hydrolysis of isoxazoles. The antiproliferative activity of title compounds were evaluated against leukemia-, carcinoma-, neuroblastoma-, and sarcoma-derived human cell lines in comparison to the natural compound geiparvarin. The structure activity relationship indicated that the maximum in vitro antiproliferative activity correlates with the presence of a heterocyclic ring on the ethenyl moiety.
