Lumisterol
Lumisterol (9β,10α-Ergosterol) is a photoproduct of 7-dehydrocholesterol, present in the skin, and acts as an orally active VDR non-genomic modulator and ROR inverse agonist. Lumisterol binds to the SARS-CoV-2 Mpro substrate-binding pocket and the RdRP active site, inhibiting enzyme activity. Lumisterol induces NRF2-regulated antioxidant responses, p53 phosphorylation and nuclear translocation, and intracellular free radical scavenging. Lumisterol inhibits the proliferation of epidermal keratinocytes and melanoma cells, modulates cell cycle progression, and suppresses basal and TNFα-induced NFκB transcriptional activity. Lumisterol inhibits RORγ transcriptional activity and IL-17 production. Lumisterol is used in research on UVB-induced skin damage, melanoma, psoriasis, vitamin D deficiency, and COVID-19.

体外実験
Lumisterol shows favorable docking scores and binding poses in the LBDs of RORα and RORγ, consistent with its role as a ligand for these receptors[2].
In human malignant melanoma A375 and SK-MEL-28 cell lines, treatment with 100 nM Lumisterol (100 nM; 72 h) enhances the migration of A375 cells and SK-MEL-28 cells[4].
In human malignant melanoma A375 cell line, 100 nM Lumisterol (100 nM; 48 h) increases the proportion of cells in the G0/G1 phase and decreases the percentage in G2/M, but has no effect on SK-MEL-28 cells[4].
In human malignant melanoma SK-MEL-28 cell line, 100 nM Lumisterol (100 nM; 24 h) causes a small but significant increase in CYP24A1 mRNA levels, but has no effect on CYP24A1 or other vitamin D metabolizing genes in A375 cells[4].
Lumisterol (1150 µW cm-2 UV-B pre-exposure; 30 min pre-exposure, 8 h thermal) is converted to Vitamin D2 (HY-76542) in a cell-free system, with the strongest conversion occurring when lumisterol is pre-exposed to UV-B light[5].
Lumisterol (24-72 h) incubation of a UV-B-exposed yeast diet at 37 °C results in a time-dependent conversion of Lumisterol to Vitamin D2, with a 63% increase in Vitamin D2 content after 72 h[5].
In human malignant melanoma A375 and SK-MEL-28 cell lines, Lumisterol (1 μM; 72 h) fails to inhibit cell proliferation, and instead increases proliferation by 10% in SK-MEL-28 cells[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
