Use of L-SepiapterinL-Sepiapterin (Sepiapterin) is a precursor of the endothelial nitric oxide synthase (eNOS) cofactor tetrahydrobiopterin (BH4). L-Sepiapterin improves endothelial dysfunction in small mesenteric arteries from db/db mice, and induces angiogenesis. L-Sepiapterin inhibits cell proliferation and migration of ovarian cancer cells via down-regulation of p70S6K-dependent VEGFR-2 expression[1][2]. |

| In Vitro | L-Sepiapterin (Sepiapterin) (0.1-10 μM; 24 hpurs) Iinduces cell proliferation in a dose-dependent manner[1]. L-Sepiapterin (1-50 μM; 20 minutes) significantly inhibits the phosphorylation of VEGF-A-induced (50 ng/ml) p70S6K[1]. L-Sepiapterin inhibits VEGF-A-induced cell proliferation and migration through NO-independent mechanism[1]. Cell Proliferation Assay[1] Cell Line: SKOV-3 cells Concentration: 0.1, 1, 10 μM Incubation Time: 24 hours Result: Induced cell proliferation in a dose-dependent manner. |
| In Vivo | Sepiapterin (10 mg/kg; p.o. (powder chow); daily for or 8 weeks) significantly improves the relaxation to Ach in small mesenteric arteries (SMA) from db/db mice[2]. Animal Model: Male C57BL/KsJ diabetic mice (db/db)[2] Dosage: 10 mg/kg Administration: P.o. (powder chow); daily for or 8 weeks Result: Significantly improved the relaxation to Ach in SMA from db/db mice. |
