摘要
A new series of 6-aryl-5-cyano thiouracil derivatives were synthesized. Cyanouracil 1 was condensed with monochloroacetic acid and different aldehydes to give thiazolopyrimidine 2. On the other hand, treatment of cyanouracil 1 with 2-chloro-N-substituted-phenylac etamide afforded 4. Hydrazinolysis of 6 afforded the hydrazino derivatives 7 which upon reaction with different electrophilic reagents such as acetic anhydride, benzoyl chloride, and carbon disulfide yielded pyrimidine derivatives 8-15. Some of the new derivatives were explored for their antimicrobial activities. Compounds 7 and 9 have a promising activity, relatively equipotent to the reference drug. All of the new synthesized compounds were tested in vitro for their antiproliferative activities against HePG-2 and MCF-7 cell lines. Compounds 7, 9, and 2d displayed potent growth inhibitory effect toward the two cell lines more than the standard drug 5-FU. Furthermore, a docking study of the most active compounds was performed with thymidylate synthase enzyme. [GRAPHICS]
