Disclosed is a pyrroloazepine derivative or a salt thereof. The pyrroloazepine derivative is represented by the following formula (I):
wherein
the ring P represented by
means a pyrrole ring represented by the following structure:
in which R1 represents alkyl, cycloalkyl or the like, and R2 represents H or alkyl; the dashed line indicates the presence or absence of a bond; and, when the bond is present, Z2 is not present/and Z1 represents H but, when the bond is absent, Z1 and Z2 are both H; Z1 represents H and Z2 represents a group OR3 in which R3 represents H, alkyl, aralkyl or the like; Z1 and Z2 both represent groups SR4 in which R4 represents alkyl, aralkyl or the like; or Z1 and Z2 are combined together to represent O, a group NOR5 in which R5 represents H, alkyl or the like, or a C2-C3 alkylenedithio; A represents alkylene, alkenylene or alkynylene; and Y represents a group
in which W represents CH, C= or N, m stands for 0 or 1, n stands for 1, 2 or 3, G represents O, S, C=O, sulfinyl, sulfonyl, alkylene, alkenylene, acetal or the like; E1 and E2 represent H or lower alkyl group; and D represents an aromatic hydrocarbon or am aromatic heterocyclic ring. The compound (I) has strong serotonin-2 receptor antagonistic action and low toxicity and less side effects, and is useful as a therapeutic for circulatory diseases such as ischemic heart diseases, cerebrovascular disturbances and peripheral circulatory disturbances.
