<p>Spasmolytic agents have formula (I): (where A = (hetero)aromatic ring system opt. substd.; R2 = H, alk, aralkyl; R3, R4, R5, R6 = H, alkyl, alkenyl, alkynyl, aryl, aralkyl, aryloxyalkyl, arylthioalkyl; R1, R7 = H, alkyl, alkenyl, alkynyl, aryl, phenyl; provided that is not 1 of R2, R3, R4, R5, R6 is not = H and/or that ring system A is at least bisubstd.; R1 and/or R7 can also = pyridyl, pyrimidyl directly attached to posn. or by 1-3C alkylene chain; R3 + R5 opt. = 5,6,7C alkylene).</p> |
