The present invention relates to a novel tenofovir disoproxil aspartate compound. The aforementioned salt compound allows minimal formation of related substances occurring with passage of time, increasing the stability of the formulation by drastically reducing the formation of impurities during storage. Also, the need for a separate study of toxicological effects is eliminated. Moreover, the salt compound of the present invention possesses superior physicochemical properties, with a significant improvement in stability, hygroscopicity, and solubility, thereby allowing it to be used as an active ingredient along with pharmaceutically acceptable carriers for a pharmaceutical composition for the treatment of HIV infection and chronic hepatitis B.
本发明涉及一种新型替诺福韦二丙氨酸盐化合物。上述盐化合物允许在时间推移时最小化相关物质的形成,通过大幅度减少贮存期间杂质的形成,增加了配方的稳定性。此外,消除了对毒理影响进行单独研究的需求。此外,本发明的盐化合物具有优越的物理化学性质,稳定性、吸湿性和溶解度显著提高,因此可与药学可接受的载体一起用作治疗HIV感染和慢性乙型肝炎的药物组合物的活性成分。
