A series of novel 2-aminopyrimidine and 2-Substituted-4,6-diaminopyrimidine derivatives have been synthesized and their anti platelet aggregation activities were assessed against ADP and arachidonic acid- induced platelet aggregation in human plasma using light transmission aggregometry. None of the compounds showed satisfactory activity against the aggregation induced by ADP. However, satisfac...
Acylation of 2-aminothiobenzamide or 2-methylaminothiobenzamide with substituted benzoyl chlorides has been used to synthesise the corresponding 2-benzoylaminothiobenzamides whose subsequent sodium methoxide-catalysed ring closure gives the corresponding quinazoline-4-thiones. These compounds were characterised by means of their Hand C-NMR spectra. The preferred tautomeric form of selected comp...
