1. Berberine (Umbellatine) is a potent oral hypoglycemic agent with beneficial effects on lipid metabolism. 2. Berberine may as a broad-spectrum anti-microbial medicine, a complementary therapeutic agent for HIV/AIDS. 3.

As a natural dye, berberine has a colour index of 7516. 5. Berberine reduces hepatic fat content in rats with nonalcoholic fatty liver disease; also prevents proliferation of hepatic stellate cells (HSCs), which are central for the development of fibrosis during liver injury. 6. Berberine can ameliorate proinflammatory cytokines-induced intestinal epithelial tight junction damage in vitro, and berberine may be one of the targeted therapeutic agents that can restore barrier function in intestinal disease states. 7. Berberine has antineoplastic effects, including breast cancer, leukemia, melanoma, epidermoid carcinoma, hepatoma, pancreatic cancer, oral carcinoma, tongue carcinoma, glioblastoma, prostate carcinoma and gastric carcinoma, etc.

1. Chelerythrine (Broussonpapyrine) may have antimanic effect . 2. Chelerythrine can inhibit telomerase activity. 3. Chelerythrine is a well-known protein kinase C inhibitor . 4. Chelerythrine has potential antiproliferative and antitumor effects.

1. Coptisine chloride (NSC-119754) can be absorbed across intestinal epithelial cells, and completely absorbed compounds.

1. Dauricine has pulmonary toxicity, can produce pulmonary injury in CD-1 mice by the metabolism of Dauricine mediated by CYP3A. 2. Dauricinec can pass the blood-brain barrier, and that P-glycoprotein has an important role in the transportation of Dauricine across the blood-brain barrier. 3. Dauricine may has anti-tumor effect, can inhibit tumor cells in urinary system and colon cancer cell proliferation, invasion; induce cell apoptosis by suppressing NF-kappaB activity and the expression profile of its downstream genes.

Daurisoline ((R,R)-Daurisoline) is a hERG inhibitor. Daurisoline is also an autophagy blocker.

Chelerythrine Chloride is a cell-permeable inhibitor of protein kinase C, competitive with respect to the phosphate acceptor and non-competitive with respect to ATP.
