An N-substituted imidazole carboxylate compound is of formula (I). In formula (I), C* is an R-type chiral carbon atom, R1 and R2 are independently selected from H, methyl, ethyl, cyclopropyl, cyclobutyl or isopropyl, or R1 and R2 form a C2˜5 alkylenyl group; R3 is a substituted or unsubstituted C1-18 saturated or unsaturated aliphatic hydrocarbon or aromatic hydrocarbon, in which the aliphatic hydrocarbon comprises a straight chain, branched chain or cyclic aliphatic hydrocarbyl. The compound or pharmaceutically acceptable salts thereof can be used to prepare central inhibitory drugs that exert sedative, hypnotic and/or anesthetic effects on humans or animals, and can produce rapid and reversible anesthetic effects, and can be rapidly metabolized into an inactive etomidate acid, and after drug withdrawal, the wake-up quality is good; and the body's corticosteroid function can be rapidly recovered after a single administration or continuous administration.
一种 N-取代咪唑羧酸盐化合物如式(I)所示。式(I)中,C*为 R 型手性碳原子,R1 和 R2 独立选自 H、甲基、乙基、环丙基、环丁基或异丙基,或 R1 和 R2 构成 C2˜5 烷烯基;R3 为取代或未取代的 C1-18 饱和或不饱和脂肪烃或芳香烃,其中脂肪烃包括直链、支链或环状脂肪烃基。该化合物或其药学上可接受的盐类可用于制备对人或动物发挥镇静、催眠和/或麻醉作用的中枢抑制药物,能产生快速、可逆的麻醉作用,并能迅速代谢为无活性的依托咪酯酸,停药后苏醒质量好;单次给药或连续给药后,机体皮质激素功能可迅速恢复。
