  Synthesis and biological evaluation of new 3-trifluoromethylpyrazolesulfonyl-urea and thiourea derivatives as antidiabetic and antimicrobial agents

  摘要：

  Fluorinated pyrazoles, and benzenesulfonylurea and thiourea derivatives as well as their cyclic sulfonylthioureas 2-18 were prepared as hypoglycemic and antibacterial agents. The chemistry involves the condensation of 4-hydrazino benzenesulfonamide hydrochloride with 1-trifluoromethyl diketones 1 to give pyrazole derivatives 2 which upon bromination gave the bromopyrazole 3. Reaction of 2 or 3 with isocyanates and isothiocyanates gave the corresponding ureas 4 and 5 and thioureas 6 and 7. Cyclization of thiourea derivatives with ethyl bromoacetate, ethyl beta-bromopropionate, 1,3-dichloroacetone and alpha-bromoacetophenone yielded the corresponding 4-oxothiazolidines 8 and 9, 4-oxo-5,6-dihydrothiazine 10, 5-oxo-4,5-dihydrothiazines 11 and 12 and thiazolines 13 and 14. Preliminary biological screening of the prepared compounds revealed significant antidiabetic and antibacterial activities. (C) 2010 Elsevier B.V. All rights reserved.
