L-Sepiapterin
Based on 1 publication(s) in Google Scholar
L-Sepiapterin (Sepiapterin), is a phenylalanine hydroxylase activator, 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. L-Sepiapterin can be used for the study of hyperphenylalaninemia.
