Product Introduction

Bioactivity
Description
Tetrahydrobiopterin (BH4) is a cofactor for aromatic amino acid hydroxylases and an essential cofactor for nitric oxide synthase (NOS), which is used in the study of endothelial dysfunction such as hypertension, hypercholesterolemia, and diabetes.
In vitro
Microglia cultures under hyperoxic conditions were supplemented with or without Tetrahydrobiopterin (100 μM). Exposure of microglia to hyperoxia-induced oxidative stress for 24 h showed a significant increase in TSP-1 mRNA expression and protein compared with normoxia (21% O2). Tetrahydrobiopterin supplementation significantly prevents hyperoxia-induced microglial activation and prevents microvascular damage in choroidal explants by reducing Iba-1 and TSP-1 expression.[1]
In vivo
To assess the levels of tetrahydrobiopterin in the retina, three to five retinal pools were collected from WT and HPH-1 mice at postnatal ages 7, 14, and 22 years and evaluated by LC-MS/MS. LC-MS/MS analysis confirmed that the concentration level of tetrahydrobiopterin in the retinal tissue of HPH-1 mice was significantly reduced by approximately 90% compared with WT groups P7, P14, and P22, respectively.[1]

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
