The anti-tumor effects of Celastrus orbiculatus Thunb. and its monomer composition: A review.

Abstract

Celastrus orbiculatus Thunb. has been included in "The Plant List" (http://www. theplantlist.org) and is the most widely researched species in its genus. It is called Nanshe Teng in China. Celastrus orbiculatus Thunb. is a plant of Euonymus and it's medicinal part is the vine and stem. It is also called Alias Dragon grass, Yellow Yine, etc. It has good anti-tumor, anti-inflammatory and other effects. More and more studies have shown that Celastrus orbiculatus Thunb. has a significant therapeutic effect on a variety of malignant tumors. The research on Celastrus orbiculatus Thunb. has a good application prospect for the development of anti-tumor drugs. However, no systematic reports on Celastrus orbiculatus Thunb. have been published before. This paper summarizes the metabolic products for anti-tumor and the mechanism for anti-tumor of Celastrus orbiculatus Thunb. to provide reference for further development and research. The relevant information on Celastrus orbiculatus Thunb. was collected from the scientific databases including PubMed, CNKI, ScienceDirect, Wiley, Springer, Web of Science, Google Scholar, Baidu Scholar, Pharmacopoeia of the People's Republic of China and Flora Republicae Popularis Sinicae, etc. RESULTS: At present, more than 200 compounds have been identified from Celastrus orbiculatus Thunb., including terpenoids, flavonoids, phenylpropanoids, polyketides and benzene derivatives, etc. Pharmacological studies have shown that Celastrus orbiculatus Thunb. has a variety effects of inhibiting tumor cell proliferation, inducing tumor cell apoptosis, inhibiting tumor cells invasion, metastasis and angiogenesis, reversing multi-drug resistance, and also collaborativing Micro RNA to inhibit tumor growth, etc. It has a significant effect on gastric cancer, liver cancer, lung cancer, etc. The extracts of Celastrus orbiculatus Thunb. have been widely used in experiments, and the toxic and side effects are small. Celastrus orbiculatus Thunb. is rich in chemical constituents, diverse in pharmacological activities and abundant in resources, which is widely used in clinics from traditional to modern. However, there is no systematic report on the chemical compounds and anti-tumor effects of Celastrus orbiculatus Thunb. We organize and summarize it to provide reference for further development and research.
