Description

technical field [0001] The present invention relates to a novel complex of gambogic acid compounds, a preparation method thereof, a pharmaceutical composition containing the complex as an active ingredient, and their application in preparing drugs for treating tumors. Background technique [0002] Studies have shown that gambogic acid compounds have an inhibitory effect on tumor cells, but the solubility of gambogic acid compounds in water is extremely small, thus affecting their medicinal value. [0003] In recent years, academic circles have devoted themselves to improving the water solubility of gambogic acid compounds, looking for suitable compounds that can be combined with gambogic acid compounds to improve their solubility in water. [0004] People such as You Qidong of China Pharmaceutical University have proposed a compound (publication number CN1309125A, Chinese invention patent application on August 22, 2001) with arginine, lysine and gambogi...
