Abstract
Abstract This invention relates to novel 6-(imidazolylphenyl)-4-iminopyrimidinone compounds having antihypertensive and platelet aggregation inhibition activity. More particularly, the present invention relates to a novel class of pyrimidinone derivatives represented by the formula ##STR1## and the pharmaceutically acceptable salts thereof wherein X may be one to three substituents selected from the group consisting of R,--OR,--SR,--NHR,--NR 2 , Cl, Br, F, NO 2 ,--COCH 3 , --COOH,--COOR,--CONHR,--CONR 2 , and --OH; and where R represents lower alkyl having 1-6 carbon atoms.
