The present invention offers a tracheal smooth muscle relaxant containing the compound represented by the following formula (1) or pharmacologically acceptable salt thereof as an effective ingredient.
[In the formula, X and Y each is any group selected from a group consisting of CH2, CHW1 (where W1 is halogen atom, hydroxyl group or lower alkoxy group) and C=O when the bond of X and Y is a single bond while, when it is a double bond, X and Y each is any group selected from a group consisting of CH and COW2 (where W2 is lower alkyl group or lower alkylcarbonyl group); Z is O, S, S=O or SO2; and R1∼R8 each is selected from a group consisting of hydrogen atom, VR9 (where V is O, S, S=O or SO2; and R9 is hydrogen atom, lower alkyl group, hydroxy lower alkyl group, lower acyl group, trihalomethyl group or carboxyl lower alkyl group), carboxyl lower alkyl group, hydroxy lower alkyl group, hydroxy lower alkenyl group, hydroxy lower alkynyl group, halogen atom, lower alkyl group, lower alkyl ketone, trihalomethyl group, trimethylsilylethynyl, nitro group, amino group, N-carbonyl lower alkyl group, lower alkylphenyl group and phenyl group].
本发明提供了一种气管平滑肌松弛剂,其有效成分含有下式(1)所代表的化合物或其药理上可接受的盐。
[式中,当 X 和 Y 的键为单键时,X 和 Y 各为选自 CH2、CHW1(其中 W1 为卤原子、羟基或低级烷氧基)和 C=O 组成的组中的任意基团;而当为双键时,X 和 Y 各为选自 CH 和 COW2(其中 W2 为低级烷基或低级烷基羰基)组成的组中的任意基团;Z是O、S、S=O或SO2;以及 R1∼R8各自选自由氢原子、VR9(其中V是O、S、S=O或SO2;R9为氢原子、低级烷基、羟基低级烷基、低级酰基、三卤甲基或羧基低级烷基)、羧基低级烷基、羟基低级烷基、羟基低级烯基、羟基低级炔基、卤素原子、低级烷基、低级烷基酮、三卤甲基、三甲基硅烷基、硝基、氨基、N-羰基低级烷基、低级烷基苯基和苯基]。
