Description
L-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.

How to use
In Vitro:
L-Sepiapterin (Sepiapterin) (0.1-10 μM; 24 hpurs) Iinduces cell proliferation in a dose-dependent manner. L-Sepiapterin (1-50 μM; 20 minutes) significantly inhibits the phosphorylation of VEGF-A-induced (50 ng/ml) p70S6K. L-Sepiapterin inhibits VEGF-A-induced cell proliferation and migration through NO-independent mechanism.
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.
