摘要: 目的: 评价新型抗胆碱能药物盐酸戊乙奎趾 (PHC)及其4个光学异构体 R-L、R-2, S-1和 S-2的 细胞毒性。方法: 不同浓度的PHC及其光学异构体作用HepG2细胞24 h后,采用MTT法和中性红吸收法测定细胞毒性。结果: PHC及其光学异构体均能浓度依赖性地降低细胞存活率。根据半数抑制浓 度(IC50)比较这5个抗胆碱能化合物的细胞毒性: MTT法所测定的细胞毒性强弱次序为PHC>R-2>R-1 > S-2 > S-1,中性红吸收法所测定的细胞毒性强弱;弱次序为 R-2> PHC ≈ R-1 > S-2 > S-1。结论: 就HepG2细胞而言,R构型异构体的细胞毒性强于S构型 并且,在PHC的4个光学异构体中,R-2的细胞毒性相对最强,而 S-1相对最弱。

Abstract: AIM: To evaluate the cytotoxicity of anovelanticholinergic drug penehyelidine hydrochloridle(PHC) and its four optical isomers R-1, R-2, S-1, and S-2. METHODS: Two in vitro assays. MTT assay andneutral red uptake 198ay, were used to evaluate the cyto-toxicity following PHC and its isomers exposure to HepG2cells at different concentrations. RESULTS: PHC and itsisomers induced decreases of viability of HepG2 ceils in aconcentration-dependent manner. Comparison of the cyto-toxicity of the five anticholinergic agents with 50% inhibi-tory concentration (ICg) values indlicated that the orderof potency was PHC> R-2> R-1> S2> S-1 for MTTassay, and R-2> PHC ≈ R-1> S2> S-1 for neutral reduplake assay. CONCLUSION: With respect to the cyto-toxicity of the four isomers on HepG2 cells, the config-uration was more potent than the S configuration, and R-2 was the most potent isomer whereas S-! was the leastpotent isomer among the four optical isomers.
