Lumisterol 3 (>90%) (9β,10α-Cholesta-5,7-dien-3β-ol) is a normal human secosterooid metabolite from the class of vitamin D3 photoisomer derivatives. Lumisterol 3 (>90%) is used in the preparation of vitamin D[1].
In Vitro: Lumisterol 3 (L3) (1-100 nM, 24 h) significantly reduces UVB-induced cellular oxidant formation in a dose-dependent manner and inhibits the proliferation of UVB-irradiated keratinocytes[2].
Lumisterol 3 (L3) (100 nM, 24 h) promotes repair of cellular DNA damage induced by UVB irradiation and increases the nuclear/cytosolic Nrf2 ratio and nuclear p53 expression level in UVB-irradiated cells[2].
Lumisterol 3 (L3) (100 nM, 3 h) significantly enhances the expression levels of Nrf2-regulated antioxidant proteins, including catalase and HO-1 in UVB-irradiated cells[2].
