Tetrahydrobiopterin biosynthesis, utilization and pharmacological effects

Area of Science:

• Biochemistry
• Molecular Biology
• Pharmacology

Background:

• Tetrahydrobiopterin (H4-biopterin) is an essential cofactor for enzymes hydroxylating aromatic amino acids, ether lipid oxidase, and nitric oxide synthases (NOS).
• H4-biopterin is crucial for neurotransmitter formation, vasorelaxation, and immune responses, with its biosynthesis regulated by hormones and immune stimuli in mammals.
