biological activity | Lycorine is a natural alkaloid extracted from the family of golden Ophthalmic plants. Lycorine is a potent orally active SCAP inhibitor with a Kd value of 15.24 nM. Lycorine down-regulates SCAP protein levels without altering their transcription. Lycorine is also an inhibitor of melanoma angiogenesis. Lycorine has potential for the study of prostate cancer and metabolic diseases. |
Target | Kd: 15.24 nM (SCAP) |
Cell Line: | HL-7702/SRE-Luc cells HL-7702/SRE-Luc cells C8161 cells |
Concentration: | 16 hours 2 hours, 4 hours, 8 hours, 12 hours, 16 hours 0 μM, 1.56 μM, 3.13 μM, 6.25 μM, 12.5 μM, 25 μM |
Incubation Time: | 5 μM; 10 μM; 20 μM; 40 μM 10 μM; 20 μM 48 hours |
Result: | Had no cytotoxicity on HL-7702 cells. Decreased p-SREBF1, m-SREBF1, p-SREBF2 and p-SREBF1 protein expression. Markedly suppressed the expression of VE-cadherin in a dose-dependent manner and also slightly diminished the expression of Sema4D in C8161 cells. Ameliorated high-fat diet-induced hyperlipidemia, hepatic steatosis, and insulin resistance in mice. |
Animal Model: | High-fat diet (HFD)-fed C57BL/6J mice |
Dosage: | 15 mg/kg, 30 mg/kg |
Administration: | Oral chow; once daily |
Use | oral administration or subcutaneous injection of lycorine has the effects of salivation, sub-heart and increased tracheal secretion, therefore, its preparation has been used as an expectorant in some cases. Lycorine has significant emetic effect. The potency is stronger than that of the root of the root, but not as good as the opioid morphine. After hydrogenation, lycorine produces dihydrolycorine, which has strong anti-amoebic dysentery effect and less toxicity, and has been used in clinic. The enamine salt made of lycorine showed anti-seed tumor effect in animals. Traditional Chinese Medicine iron color arrow, black garlic has expectorant effect, the reason is containing lycorine. |
production method | This product is an isoquinoline alkaloid widely found in plants of the family Lycoris, which can be obtained from Lycoris radiata. Etc. The bulbs were extracted. |
