As epoxy functional group has high anticancer activity, α, β-epoxyketones were designed and synthesized as new anticancer agents, and their structures were confirmed by UV, 1H NMR, IR, MS technigeces and elemental analysis. Their in vitro anticancer activities were evaluated by MTF method and the results showed that the compound 4c exhibited good activity with IC50 of 17.8, 22.0 and 24.1 μg/mL against A-549, Hela and HepG2 cells, respectively. The dose of LD50 of the mice by intragastric administration was 1864.4 mg/kg. Therefore, the α, β-epoxyketones could potentially provide as new anticancer agents. 展开更多

目的:建立HPLC法用于测定大鼠血浆中葛根素的浓度,并研究格列本脲对葛根素在大鼠体内药动学行为的影响。方法:将18只大鼠分成3组:第1组葛根素单独给药组;第2组先给格列本脲,1.5 h后给予葛根素;第3组先给葛根素,0.5 h后给予格列本脲... 目的:建立HPLC法用于测定大鼠血浆中葛根素的浓度,并研究格列本脲对葛根素在大鼠体内药动学行为的影响。方法:将18只大鼠分成3组:第1组葛根素单独给药组;第2组先给格列本脲,1.5 h后给予葛根素;第3组先给葛根素,0.5 h后给予格列本脲。血浆样品用3倍量乙腈沉淀蛋白,进样分析。色谱柱为Diamonsil C18(200 mm×4.6 mm,5μm),流动相为乙腈-0.5%醋酸水(14∶86),柱温30℃,检测波长249 nm。结果:葛根素血浆浓度的线性范围为0.045 0~3.60μg·m L^-1(r〉0.998),定量下限为0.045 0μg·m L^-1。日内和日间精密度(RSD)均小于13%,准确度(RE)在1.1%~14%。与单独给药组相比,第2组葛根素的Cmax升高了71.9%(P〈0.01),AUC0~t和AUC0~∞分别增加了34.9%和36.0%(P〈0.05);第3组葛根素的药动学参数无明显变化(P〉0.05)。结论:推测格列本脲在大鼠体内可能促进葛根素的吸收或抑制其代谢,而对其消除过程无明显影响。 展开更多
