ETHNOPHARMACOLOGY RELEVANCE: As a Yi medicine for eliminating wind to relieve pain, Tinospora sagittata var. yunnanensis (S. Y. Hu) H. S. Lo (TSY) is widely used to treat sore throat, stomach pain, bone and muscle injuries, and tumors; however, the material basis and mechanism of action remain unclear.
AIM OF THE STUDY: This study aims to investigate the potential active compounds of TSY and related pharmacological mechanisms against gastric cancer using a multitarget strategy.
MATERIALS AND METHODS: The main chemical components of TSY were collected through a literature review and database searches. The components were further screened for ADMET properties, and their targets were predicted using network pharmacology (admetSAR) and substructure-drug-target network-based inference (SDTNBI) approaches in silico. The pharmacological mechanism of action of TSY extract for pain relief, sedation, and anti-gastric cancer activities were identified via in vivo and in vitro biochemical analyses.
RESULTS: Here, 28 chemical components were identified, 7 active compounds were selected, and 75 targets of TSY extract were predicted. A compound-target-disease network topological approach revealed that the predicted targets are highly related to the digestive system and nervous system. Network pharmacology results suggested that the anti-gastric cancer activity of TSY was highly correlated with its analgesic and sedative targets and MAPK. In vivo experiments confirmed that TSY extract not only reduced the number of voluntary activities in the mouse model but also exhibited a synergistic effect on sodium pentobarbital-induced sleep, reduced the number of mice exhibiting writhing responses to acetic acid, and increased the hot plate pain threshold of mice. Thus, TSY extract exhibits good analgesic and sedative effects. The TSY extract inhibited HGC-27 cell proliferation and induced apoptosis by regulating apoptotic proteins (BAX, BCL-2 and BCL-XL) in vitro.
CONCLUSIONS: TSY exhibits combined analgesic, sedative, and anti-gastric cancer activities.
