  One-pot synthesis and anticancer studies of 2-arylamino-5-aryl-1,3,4-thiadiazoles

  摘要：

  A series of 2-arylamino-5-aryl-1,3,4-thiadiazoles 1a-j were synthesized and screened for their anticancer activity against various human cancer cell lines. The novel one-pot synthesis of 1,3,4-thiadiazoles was achieved by refluxing aryl aldehydes, hydrazine hydrate, and aryl isothiocyanates in methanol followed by oxidative cyclization with ferric ammonium sulfate. The compounds 1g-j with trimethoxyphenyl at the C-5 position displayed extremely potent anticancer activity with at least twofold selectivity (IC(50): 4.3-9.2 mu M). The nature of substituent on the C-2 arylamino ring may be critical in opting for the selectivity towards a particular cancer cell. (C) 2011 Elsevier Ltd. All rights reserved.

  New series of 2,5-dihydroxyphenyl-1,3-thiazoles 4a-l was synthesized by reacting 2,5-dihydroxyphenacyl bromide with various 4-aryl thiosemicarbazones 3a-l that on oxidation with ferric chloride yielded the corresponding N (1)-substituted benzylidene-N (2)-[3-aryl-4-(1,4-benzoquinon-2-yl)-1,3-thiazol-2-ylidene]hydrazines 5a-l. They were evaluated for antibacterial activity against Staphylococcus aureus and Bacillus subtilis as Gram-positive bacteria, Escherichia coli and Pseudomonas aeruginosa as Gram-negative bacteria. They were also evaluated for their in vitro antifungal potential against Candida albicans. Almost all tested compounds were found to possess variable degrees of antimicrobial activity. The obtained data revealed that compounds 4b-h and 5e, 5f and 5l exhibited promising antimicrobial activity against the tested organisms of which compound 4b proved to be the most active.
