生物活性

Lycorine is a natural alkaloid extracted from theAmaryllidaceaeplant. Lycorine is a potent and orally activeSCAPinhibitor with aKdvalue 15.24 nM. Lycorine downregulates the SCAP protein level without changing its transcription[2]. Lycorine is also amelanoma vasculogenicinhibitor[3]. Lycorine can be used for the study of prostatecancerand metabolic diseases[2].

IC50& Target

Kd: 15.24 nM (SCAP)[1]

体外研究
(In Vitro)

Lycorine inhibits cell proliferation in a dose-dependent manner in the abovementioned 4 PCa cell lines, and the IC50ranged from 5 μM to 10 μM., it also shows Lycorine has little effects on PNT1A cell's proliferation[1].
SCAP (SREBF chaperone) is an ER-toGolgi transport protein, undergoes a conformational change, and regulates/preserves SREBFs in the ER by forming a complex with INSIG1 (insulin induced gene 1)[2].
Lycorine (5-40 μM; 16 hours) significantly suppresses SREBFs activity (up to -70%) in a dosedependent manner and does not cause obvious cytotoxicity in cells[2].
Lycorine (10-20 μM; 2-16 hours) dose- and time-dependently decreases the mature SREBF1 and SREBF2 proteins in HL-7702 cells[2].
Lycorine (20 μM; 16 hours) neither activates NR1H3 transcription nor affect NR1H3 target genes, including ABCG5 and ABCG8, but Sterols activates NR1H3 transcription activity[1].
Lycorine hydrochloride (0-25 μM; 48 hours) treatment markedly suppresses the expression of vascular endothelial (VE)-cadherin in a dose-dependent manner and also slightly diminishes the expression of Sema4D in C8161 cells. However, the expression of the other six genes is not affected[3].
Lycorine hydrochloride (0-25 μM; 48 hours) treatment markedly reduces VE-cadherin protein levels in C8161 cells in a dose-dependent fashion[3].

Cell Viability Assay[2]

Cell Line:HL-7702/SRE-Luc cells
Concentration:16 hours
Incubation Time:5 μM; 10 μM; 20 μM; 40 μM
Result:Had no cytotoxicity on HL-7702 cells.

Western Blot Analysis[2]

Cell Line:HL-7702/SRE-Luc cells
Concentration:2 hours, 4 hours, 8 hours, 12 hours, 16 hours
Incubation Time:10 μM; 20 μM
Result:Decreased p-SREBF1, m-SREBF1, p-SREBF2 and p-SREBF1 protein expression.

RT-PCR[3]

Cell Line:C8161 cells
Concentration:0 μM, 1.56 μM, 3.13 μM, 6.25 μM, 12.5 μM, 25 μM
Incubation Time:48 hours
Result:Markedly suppressed the expression of VE-cadherin in a dose-dependent manner and also slightly diminished the expression of Sema4D in C8161 cells.
体内研究
(In Vivo)

Lycorine (oral chow; 15 mg/kg, 30 mg/kg; once daily) alleviates fat accumulation and metabolic syndrome, increases lipolysis and betaoxidation of fatty acid along with precursor and mature SREBFs in mice[2].

Animal Model:High-fat diet (HFD)-fed C57BL/6J mice[2]
Dosage:15 mg/kg, 30 mg/kg
Administration:Oral chow; once daily
Result:Ameliorated high-fat diet-induced hyperlipidemia, hepatic steatosis, and insulin resistance in mice.
