  Twenty-six derivatives of 5- and 7-oxo or 5- and 7-aminothiazolo[3,2-a]pyrimidines were prepared and evaluated as positive inotropic, anti-inflammatory and antihypertensive agents both in vitro and in vivo. The structures of the 5- and 7-isomers have been confirmed unambiguously by IR, UV, H-1 and C-13 NMR and MS. The structure of 1a was confirmed by the synthesis of compound 1 whose structure had been previously established by X-ray analysis. The 5-aminothiazolo-pyrimidine-6-carbonitrile derivatives 5a and 5e exhibited potent inotropic activities. 5e was more potent than the classical reference amrinone. Three compounds 5e, 5i and 5j displayed moderate antihypertensive activities. The 4-chlorophenyl derivative 5d exhibited an anti-inflammatory activity 2-fold that of aspirin. This study has demonstrated that thiazolo[3,2-a]pyrimidine compounds have interesting biological potentialities, particularly as inotropic agents, a field which had never been explored so far for this series.
