This invention pertains to novel substituted pyrazolyl compounds useful as intravenous anesthetics represented by the Formula: ##STR1## including geometric and optically active isomeric forms, and the pharmaceutically acceptable acid addition salts thereof, wherein: one of Y and Z is nitrogen, and the other is CH; R.sub.1 is hydrogen or lower-alkyl; R.sub.2 and R.sub.3 are selected from the group consisting of hydrogen, --CHO, lower-alkylcarbonyl, lower-alkoxy carbonyl, lower-alkylaminocarbonyl, lower-alkyl, lower-alkenyl, lower-alkoxy-lower-alkenyl, lower-alkylcarbonyloxymethyl, substituted and unsubstituted heterocyclic rings, and substituted or unsubstituted aryl groups, wherein the symbol * represents a carbon atom which may be asymmetric and at least one of R.sub.2 and R.sub.3 is other than hydrogen.
本发明涉及一种新型取代吡唑基化合物,其可作为静脉麻醉剂使用,其化学式为:##STR1## 包括几何和光学异构体形式以及其药学上可接受的酸加成盐,其中:Y和Z中的一个是氮,另一个是CH;R.sub.1是氢或低碳基;R.sub.2和R.sub.3从以下群体中选择:氢,--CHO,低碳基羰基,低碳基氧羰基,低碳基氨基羰基,低碳基,低烯基,低碳基氧基-低烯基,低碳基羰氧甲基,取代和未取代的杂环环和取代或未取代的芳香族基团,其中符号*表示可能是不对称的碳原子,且R.sub.2和/或R.sub.3中至少有一个不是氢。
