The present invention provides an agent for prevention and/or treatment of asthma comprising a substance capable of suppressing the function involved in signal transduction of GPR4 as an active ingredient. It also provides an agent for prevention and/or treatment of asthma which comprises a nitrogen-containing tricyclic compound represented by the formula (I) or a quaternary ammonium salt thereof, or a pharmaceutically acceptable salt thereof;
[wherein R1 represents a substituted or unsubstituted lower alkyl, or the like; R2 represents hydrogen, a substituted or unsubstituted lower alkyl, or the like; R3 and R4 are the same or different and each represents hydrogen, lower alkyl, or the like; n represents 0 or 1; X represents -(CH2)2-, or the like; and Y represents the formula (II)
(wherein W represents CH or a nitrogen atom; Z1 and Z2 are the same or different and each represents hydrogen, a substituted or unsubstituted lower alkyl, or the like; and Z3 represents hydrogen, a substituted or unsubstituted lower alkyl, or the like)] as an active ingredient.
本发明提供了一种用于预防和/或治疗哮喘的制剂,其活性成分包括一种能够抑制参与 GPR4 信号转导功能的物质。本发明还提供了一种用于预防和/或治疗哮喘的制剂,该制剂包含由式(I)代表的含氮三环化合物或其季铵盐,或其药学上可接受的盐;
[其中 R1 代表取代或未取代的低级烷基或类似物;R2 代表氢、取代或未取代的低级烷基或类似物;R3 和 R4 相同或不同,各自代表氢、低级烷基或类似物;n 代表 0 或 1;X 代表-(CH2)2- 或类似物;Y 代表式 (II)
(其中 W 代表 CH 或氮原子;Z1 和 Z2 相同或不同,各自代表氢、取代或未取代的低级烷基或类似物;Z3 代表氢、取代或未取代的低级烷基或类似物)]作为活性成分。
