【摘要】 目的:测定考布他丁A4前药(CA4P)的溶解度和油水分布系数。方法:用平衡法测定溶解度,摇瓶法测定油水分布系数,HPLC法测定样品含量。结果:CA4P在25oC下,在纯化水、甲醇中的溶解度分别为349.82、3.5 mg/ml。CA4P的油水分布系数P接近于0。结论:CA4P亲脂性弱,口服不易吸收。更多还原

【Abstract】 Object: To determine the solubility and partition coefficient of combretastatin A4 prodrug(CA4P).Methods: Solubilities in water and in methanol were determined by the equilibrium method,and the partition coefficient in n-caprylic alcohol/water system was measured by shaking flask method with HPLC.Results: At 25 ℃,the solubility of CA4P in water was 349.8 mg/ml,in methanol was 23.5 mg/ml.The partition coefficient of CA4P was zero.Conclusion: CA4P was not absorbed in the intestinal tract.更多还原
