SYNTHESIS AND IN VITRO EVALUATION OF SOME NEW PYRIMIDINES AND RELATED CONDENSED RING SYSTEMS AS POTENTIAL ANTICANCER AGENTS

摘要

Several new pyrimidines 6-11, 18-20, furo-, thieno-, and pyrrolo[2,3-d]pyrimidines 3, 8, 12, triazolo[4,3-a]pyrimidines 14, 15, 16 and tetrazolo[1,5-a]pyrimidine 17 were prepared from the known intermediate 5-(2-hydroxyethyl)-6-methyl-2-thiouracil (2). Compound 7 (4-chloro-5-(2-chloroethyl)-2-methylthio-6-methyl-pyrimidine) exhibited weak antitumor activity in vitro. [References: 9]
