MedKoo Cat#: 330141 | Name: Sapropterin HCl
Featured New

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Sapropterin, also known as Tetrahydrobiopterin (BH4, THB, trade name Kuvan) or sapropterin (INN) is a naturally occurring essential cofactor of the three aromatic amino acid hydroxylase enzymes, used in the degradation of amino acid phenylalanine and in the biosynthesis of the neurotransmitters serotonin (5-hydroxytryptamine, 5-HT), melatonin, dopamine, norepinephrine (noradrenaline), epinephrine (adrenaline), and is a cofactor for the production of nitric oxide (NO) by the nitric oxide synthases. Chemically, its structure is that of a reduced pteridine derivative.

Biological target:
Sapropterin HCl is a cofactor that facilitates the production of aromatic amino acids, neurotransmitters, and nitric oxide when bound to specific enzymes. Sapropterin HCl acts as a radical-trapping antioxidant, inhibiting phospholipid oxidation in lipid membranes. Sapropterin HCl inhibits ferroptosis in various cell types, such as IKE- or RSL3-induced ferroptosis in HT-1080 cells (EC50 = 21 and 69 µM) and ferroptosis induced by the knockout of glutathione peroxidase (Gpx4-/-) in immortalized mouse fibroblasts. It reduces RLS3-induced lipid peroxidation in murine fibroblasts and HT-1080 cells when used at a concentration of 50 µM.
In vitro activity:
In vitro, the study investigated the transport of sapropterin across the plasma membrane. Sapropterin supplementation is used to address Sapropterin deficiencies, although its rapid clearance presents challenges. This research identified hENT2 as a key transporter for precursor pterins, such as sepiapterin, BH(2), and sapropterin, impacting intracellular BH(2)/sapropterin ratios. Reference: Mol Genet Metab. 2011 Jan;102(1):18-28. https://pubmed.ncbi.nlm.nih.gov/20956085/
In vivo activity:
The study suggests that sapropterin may exacerbate autoimmune CNS diseases, with lipid disruptions playing a mechanistic role. Mice with immunization-induced autoimmune encephalomyelitis (EAE), a model of multiple sclerosis, were treated with sapropterin. The results indicated that sapropterin treatment led to higher EAE disease scores and increased T-cell infiltration in the spinal cord. This was associated with changes in lipid profiles known to disrupt the blood-brain barrier in EAE mice.

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
