A pyrrolesulfonamide compound having the following formula (I):
wherein the ring P represented by
is a pyrrole ring having the following structure:
wherein 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 when W is CH or N, or m stands for 1 when W is C═; B represents a specific divalent group; E1 and E2 each independently represents H or lower alkyl; and D represents an aromatic hydrocarbon group or heterocyclic group; l stands for 0 or 1; 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 represents H and Z2 represents OH or Z1 and Z2 are combined together to represent O or a group NOR5, in which R5 represents H, or alkyl, aralkyl or aryl; and R represents H, alkyl, cycloalkyl, cycloalkyl-alkyl or aralkyl. The compound (1) has been improved in potency, selectivity to receptors other than serotonin-2 receptors, toxicity, side effects and/or the like over medicines reported to date and equipped with &agr;1-blocking action and serotonin-2 receptor antagonistic action in combination.
一种具有以下式子(I)的吡咯磺酰胺化合物:其中由P表示的环是具有以下结构的吡咯环:其中A表示烷基,烯基或炔基;Y表示具有W表示CH、C═或N的基团;当W为CH或N时,m为0或1;当W为C═时,m为1;B表示特定的二价基团;E1和E2各自独立地表示H或低级烷基;D表示芳香族烃基或杂环基;l为0或1;虚线表示键的存在或不存在;当键存在时,Z2不存在且Z1表示H,但当键不存在时,Z1表示H且Z2表示OH或Z1和Z2结合在一起表示O或NOR5基团,其中R5表示H或烷基、芳基烷基或芳基;R表示H、烷基、环烷基、环烷基烷基或芳基烷基。该化合物(1)在药物报道至今的具有&agr;1-阻滞作用和5-羟色胺-2受体拮抗作用的药物中,具有更高的效力、对除5-羟色胺-2受体外其他受体的选择性、毒性、副作用等改进。
