A method for treating a circulatory disease or condition in a mammal, which entails administering to the mammal an effective amount of a compound of the formula (I) or a pharmaceutically acceptable salt thereof:
wherein
the ring P represented by
is a pyrrole ring having the following structure:
wherein R1 represents C1-C8 alkyl, C3-C8 cycloalkyl, C4-C8 cycloalkyl-alkyl, C6-C14 aryl or C7-C22 aralkyl, which are optionally substituted; and R2 represents H or C1-C8 alkyl, which is optionally substituted; 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, C1-C8 alkyl, or C7-C22 aralkyl, which are optionally substituted; Z1 and Z2 both represent groups SR4, in which R4 represents C1-C8 alkyl or C7-C22 aralkyl, which are optionally substituted; or Z1 and Z2 are combined together to represent O, a group NOR5, in which R5 represents H, or C1-C8 alkyl or C2-C3 alkylenedithio, which are optionally substituted; A represents alkylene, alkenylene or alkynylene; and Y represents a group in which W is CH, C═ or N, m is for 0 or 1, n is for 1, 2 or 3, G is O, S, C═O, sulfinyl, sulfonyl, alkylene, alkenylene or acetal; E1 and E2 is H or C1-C8 alkyl; and D represents an aromatic hydrocarbon or an aromatic heterocyclic ring. The compound (I) has strong serotonin-2 receptor antagonistic action and low toxicity and less side effects, and is therapeutically useful in the treatment of circulatory diseases and/or conditions related thereto.
