摘要: 目的:探讨中药验方清热消 饮的抑瘤作用及其作用机制。方法:采用Accelrys 公司Cerius2 分子模拟软件包(版本4.10), 通过ligandfit 模块进行分子对接, 研究清热消 饮成分及可能形成的复合物的三维结构同Bcl-xl 、TNF-α、CDK2 受体的相互作用, 在此基础上探讨清热消 饮的可能抑瘤机制。结果:以Bcl-xl 、TNF-α和CDK2 为靶点, 与原配体的打分阈值对比, 从复方中分别筛出与其结合较好的成分有15 个、30 个和23 个, 其抗肿瘤作用机制可能是对肿瘤细胞直接的毒性作用和诱导肿瘤凋亡。同时, 抑制CDK2 而导致肿瘤细胞G1 期至S 期的移行阻滞。结论:分子对接法简单、方便、科学性强, 可用于中药复方机制的研究。

Abstract: AIM: To study the effect of Qingre Xiaozheng drink (QRXZD)on tumor growth and its mechanism.METHODS: Molecular docking serves as a method to simulate the interactions of Chinese medicine small molecules and TNF-α, Bcl-xl and CDK2 receptors by ligand-fit module of the software package Cerius2 4.10 made by Accelrys company, and we may predict QRXZD on anti-tumor mechanism.RESULTS: Fifteen molecules were shown to be better interactions with Bcl-xl than an original ligand, and thirty molecules were observed to be better interactions with TNF-αthan an original ligand. The number of molecule interacting with CDK2 was twenty three.Its mechanism could be direct toxicity for tumor cells to induce apoptosis;Simultaneously the mechanism might interfere the activity of CDK2 to stop tumor cell going ahead from G1 period to S period.CONCLUSION: Molecular docking method is simple, speedy and strong scientificness, which can be used to study the mechanism of the Chinese medicine.
