Tetrahydrobiopterine (6BH4) can diminish the oxidative stress undergone by keratinocytes and melanocytes by reducing the o-quinones generated by the oxidation of the corresponding o-diphenols. We found that 6BH4 and their analogs reduced all the o-quinones studied. The formal potentials of different quinone/diphenol pairs indicate that the o-quinones with withdrawing groups are more potent oxidants than those with donating groups.

The present invention includes delivery of isolated and purified nucleic acids that encode GTPCH proteins in nanoparticles for the treatment of endothelial cells damaged by diabetes, smoking, dyslipidemia, hypertension, and cardiovascular disease. The nanoparticles contain a nucleic acid sequence, polymer and a targeting ligand. The targeting ligand facilitates the selective delivery of the nucleic acid sequence to damaged endothelial cells. Examples involving a nucleic acid sequence encoding GTP-cyclohydrolase I (GTPCH), PEG/PEI polymers, and a monoclonal antibody or other molecule that binds to the lectin-like oxidized low density lipoprotein (LDL) receptor-1 (Lox-1) or associated molecules are presented.

A method of demethylizing an opioid to a nor-opioid is provided. The method comprises contacting an opioid with at least one enzyme. Contacting the opioid with the at least one enzyme converts the opioid to a nor-opioid. A method of converting a nor-opioid to a nal-opioid is provided. The method comprises contacting a nor-opioid with at least one enzyme. Contacting the nor-opioid with the at least one enzyme converts the nor-opioid to a nal-opioid.
