    摘要: New imidazo [1,2-c] quinazoline compounds useful as coronary smooth muscle relaxants and corresponding to the formula: ##STR1## in which: Y is oxygen or sulfur;R.sub.1 is (C.sub.1 -C.sub.6) alkyl optionally substituted by a phenyl itself optionally substituted, a (C.sub.3 -C.sub.6) cycloalkyl, optionally substituted phenyl, furyl, thienyl or acyl;R.sub.2 is hydrogen, a halogen or a (C.sub.1 -C.sub.6) alkyl optionally substituted by amino or dialkylamino;R.sub.3 is hydrogen, (C.sub.1 -C.sub.6) alkyl optionally substituted by an aryl, or R--CO--(CH.sub.2).sub.n -- [n being 1, 2 or 3, and R being (C.sub.1 -C.sub.6) alkoxy, amino, (alkyl or dialkyl)amino, morpholino or methylpiperazinyl]; andX is hydrogen or a halogen.These compounds and their physiologically tolerated salts can be used in medical treatment of coronary smooth-muscle dysfunctions.
