Synthesis and biological evaluations of some 2-thioxo-1,2,3,4-tetrahydropyrimidine derivatives

Arzneimittelforschung. 1991 Jul;41(7):725-7.

Abstract

Several 1,2,3,4-tetrahydro-6-methyl-4-(substituted phenyl)-2-thioxo-5-pyrimidinecarboxylic acid methyl esters were synthesized by condensing thiourea with methyl acetoacetate and substituted benzaldehydes according to Biginelli reaction. The structures of the compounds were confirmed by spectral and elemental analysis and their calcium antagonistic activities were investigated. Furthermore, the compounds synthesized in previous and present studies were evaluated for their antiaggregating activities.
