摘要: 目的:测定甲基对苯醌的平衡溶解度以及油水分配系数,并分析其对不同肿瘤细胞的细胞毒活性。方法:采用摇瓶法
-HPLC法测定甲基对苯醌在不同pH溶液中的平衡溶解度和油水分配系数。色谱条件:采用Ecosil-C18色谱柱(4.6 mm×250
mm,5 μm),流动相为乙腈-0.1%甲酸水溶液(70:30),流速1.0 mL/min,检测波长250 nm,柱温30 ℃,进样量10 μL。利用Swiss
ADME和pkCSM预测药物的类药性,采用MTT法分析甲基对苯醌对HT29、CT26、Caco-2、Hela、HepG2 5株细胞的细胞毒活性。
结果:甲基对苯醌在pH为1.2、2.0、5.0、6.7、7.0、7.4的溶液中,12 h的平衡溶解度分别为7.65、8.05、9.31、8.43、9.33、7.93 mg/mL,
油水分配系数分别为0.78、0.80、0.83、0.82、0.77、0.82,SwissADME预测的溶解度和油水分配系数均与实验结果一致。同时预
测结果发现,甲基对苯醌具有较好的类药性以及较弱的血脑屏障透过性。甲基对苯醌对5株细胞的IC50依次为7.98、3.21、
8.96、7.96、6.31 μmol/L。结论:测定甲基对苯醌平衡溶解度和油水分配系数的摇瓶法-HPLC法简单可行,且在pH 5.0~7.0的溶
液条件下能够适当增强甲基对苯醌的溶解度,同时药物的ADME/T在线预测软件具有一定的可靠性,甲基对苯醌对HT29、
CT26等多株细胞具有显著的抑制作用。

Abstract: Objective: To determine the equilibrium solubility and oil-water partition coefficient of methyl-p-benzoquinone, and
analyze the cytotoxic activity against different tumor cells. Methods: The equilibrium solubility and oil-water partition coefficient of
methyl-p-benzoquinone in different pH solutions were determined by shake flask-HPLC method. Chromatographic conditions: Ecosil-
C18 chromatographic column( 4.6 mm×250 mm, 5 μm), the mobile phase was acetonitrile-0.1% formic acid aqueous solution( 70 :30),
the flow rate was 1.0 mL/min, the detection wavelength was 250 nm, the column temperature was 30 ℃, and the injection amount was
10 μL. SwissADME and pkCSM were used to predict the drug likeness. The cytotoxic activity of methyl-p-benzoquinone
against HT29, CT26, Caco-2, Hela and HepG2 cells was analyzed by MTT method. Results: The equilibrium solubility of methyl-pbenquinone
in solutions with pH of 1.2, 2.0, 5.0, 6.7, 7.0 and 7.4 for 12 h was 7.65, 8.05, 9.31, 8.43, 9.33 and 7.93 mg/mL,
respectively, and the oil-water partition coefficients were 0.78, 0.80, 0.83, 0.82, 0.77, 0.82, respectively. The solubility and oil-water
partition coefficient predicted by SwissADME were consistent with the experimental results. At the same time, the prediction results
showed that methyl-p-benzoquinone had better drug likeness and weaker blood-brain barrier permeability. The IC50 of methyl-pbenzoquinone
against 5 cell lines were 7.98, 3.21, 8.96, 7.96, 6.31 μmol/L, respectively. Conclusion: HPLC method is simple and
feasible. Moreover, the solubility of methyl-p-benzoquinone can be properly enhanced under the condition of pH 5.0~7.0 solution. At
the same time, the ADME/T online prediction software for drugs has certain reliability. Methyl p-benzoquinone has significant
inhibitory effect on multiple cell lines such as HT29 and CT26.

Key words: methyl-p-benzoquinone, oil-water partition coefficient, drug likeness, equilibrium solubility, cytotoxicity
