摘要： THE PRESENT INVENTION RELATES TO PHARMACEUTICALLY ACTIVE BASICALLY SUBSTITUTED 4(3H)-QUINAZOLINONE DERIVATIVES POSSESSING EXCELLENT CORONARY DILATOR PROPERTIES AND HAVING THE STRUCTURAL FORMULA

4-(O=),3-((R3)M-C6H4-COO-CH(-CH2-R'')-CH2-),2-R1,(R2)N-

3,4-DIHYDROQUINAZOLINE

WHEREIN THE VARIOUS RADICALS HAVE THE ABOVE-GIVEN MEANINGS.

OOC-C6H4-(R3)M

R1-CO-NH-((R2)N-1,2-PHENYLENE)-CO-NH-CH2-CH(-CH2-R'')-

OR A FUNCTIONAL DERIVATIVE THEREOF: OR, THE SAID DERIVATIVES MAY BE PRODUCED BY CYCLIZING, IN THE PRESENCE OF DEHYDRATING AGENTS, 2-ACYLAMINOBENZAMIDES HAVING THE STRUCTURAL FORMULA

(R2)M-C6H4-COOH

WHEREIN R2 AND M HAVE THE ABOVE-GIVEN MEANINGS, SAID R MAY ALSO REPRESENT THE RADICAL OF THE UNDERLYING HYDROXY COMPOUND, WITH AN ALKOXY BENZOIC ACID OF THE FORMULA

(R2)M-C6H4-COO-

WHEREIN R1, R2 AND N HAVE THE ABOVE-GIVEN MEANINGS, R IS IDENTICAL WITH R'', OR, IN CASE R'' CONTAINS AN ACYLOXY RADICAL OF THE STRUCTURAL FORMULA
