人参皂苷Rb1、Rg3、Rh2 抗肿瘤作用与机制概况

人参皂苷是中药人参抗肿瘤作用的主要成分，临床药理研究表明：人参皂苷Rb1 可以通过抑制P-gp 外排药物，增强细胞对药物的敏感性，降低肿瘤细胞多药耐药性，拮抗免疫功能的抑制和维持机体对肿瘤细胞的免疫功能；Rg3 则主要通过影响肿瘤细胞蛋白质表达、作用于细胞分裂来诱导肿瘤细胞凋亡，并能抑制肿瘤新血管生长；Rh2 通过抑制肿瘤细胞增殖、诱导其凋亡、控制肿瘤细胞转移来起到抗肿瘤作用，本文通过对人参皂苷Rb1、Rg3、Rh2 抗肿瘤作用及机制的阐述，为其临床应用开发提供理论依据。

Overview of Antitumor Effects and Mechanism of Ginsenoside Rb1, Rg3, Rh2

Ginsenoside is the main component of antitumor effects of traditional Chinese medicine (TCM) Ginseng.Clinical pharmacological studies have shown that Ginsenoside Rb1 can inhibit P-gp which can lead to efflux of drugs, enhance the sensitivity of cells to drugs, reduce the multidrug resistance of the tumor cell, and maintain the immune function of the body to tumor cells. Ginsenoside Rg3 can impact tumor cell protein expression, play a role in cell division, induce tumor cell apoptosis and inhibit tumor growth of blood vessels. Ginsenoside Rh2 may play an antitumor effect by inhibiting tumor cell proliferation and metastasis, inducing tumor cell apoptosis. This article explained the antitumor effects and mechanism of Ginsenoside Rb1, Rg3, Rh2 in order to provide theoretical evidences for the clinical development and application.
