(-)-Hydroxycitric acid (HCA) can inhibit fat synthesis and reduces food intake, the primary mechanism of action of HCA appears to be related to its ability to act as a competitive inhibitor of the enzyme ATP-citrate lyase, which catalyzes the conversion of citrate and coenzyme A to oxaloacetate and acetyl coenzyme A (acetyl-CoA), primary building blocks of fatty acid and cholesterol synthesis.
Mangostanol is an acetylcholinesterase (AChE) selective inhibitor.Mangostanol has anti-cancer activity, it shows significant activities against the CEM-SS cell line, with IC50 values of 9.6 microg ml.
Garcinone E is active constituents in the anticomplement assay used. Garcinone E exhibits potent activity in vitro against Plasmodium falciparum chloroquine-resistant strain W2, with IC50 values below 3 µM. It has potent cytotoxic effect on all hepatocellular carcinomas cell lines as well as on the other gastric and lung cancer cell lines included in the screen, may be potentially useful for the treatment of certain types of cancer.
GB 2a shows antioxidant and anti-inflammatory effects, it can prevent the carrageenan-induced paw oedema. GB 2a biflavonoid can promote inhibition on tyrosinase activity and reduced melanin biosynthesis in B16F10 cells, which suggests great potential for
Beta-Tocotrienol to serve as a new anticancer agent for treating human lung and brain cancers. It inhibits the growth of both A549 (GI50=1.38±0.334μM) and U87MG (GI50=2.53±0.604μM) cells at rather low concentrations.
6-Prenylapigenin(4',5,7-Trihydroxy-6-prenylflavone) shows potent inhibitory activity on melanin formation, it may be potential sources for skin whitening agents. It also shows moderate cytotoxicities against breast cancer (MDA-MB-435S) and lung adenocarci
1,6,7-Trihydroxyxanthone has anti-cancer activity ,at least in part, through the activation of miR-218 and suppression of Bmi-1 expression; can suppress cell growth and induce apoptosis in liver cancer cells.
