Abstract
Natural products are an important original source of many widely used drugs, including anti-cancer drugs. Early research efforts for seeking anti-cancer therapy from the natural products are mainly focused on the compounds with cytotoxicity capability. The good examples include vinblastine, vincristine, the camptothecin derivatives; topotecan, irinotecan, epipodophyllotoxin derivatives and paclitaxel. In a recent decade, the fundamental progression has been made in the understanding of molecular and cellular mechanisms regarding tumor initiation, metastasis, therapeutic resistance, immune escape, and relapse, which provide a great opportunity for the development of new mechanism-based anticancer drugs, especially drugs against new molecular and cellular targets. Autophagy, a critical cell homeostasis mechanism and promising drug target involved in a verity of human diseases including cancer, can be modulated by many compounds derived from natural products. In this review, we’ll give a short introduction of autophagy and discuss the roles of autophagy in the tumorigenesis and progression. And then, we summarize the accumulated evidences to show the anti-tumor effects of several compounds derived from natural products through modulation of autophagy activity.
