  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.

  四氢生物蝶呤（6BH4）可以通过减少相应的邻二酚氧化产生的邻醌来减轻角质细胞和黑色素细胞所承受的氧化压力。我们发现，6BH4 及其类似物可以还原所研究的所有邻醌类化合物。不同醌/二酚对的形式电位表明，具有抽离基团的邻醌比具有捐赠基团的邻醌具有更强的氧化作用。

  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.

  The present invention generally relates to compositions and methods for the delivery of tetrahydrobiopterin and/or related compounds through the skin. In general, tetrahydrobiopterin may react with oxygen, and various formulations discussed herein may prevent or reduce the ability of tetrahydrobiopterin to react with oxygen. For example, in some aspects, the tetrahydrobiopterin may be contained with a composition comprising a lecithin, such as phosphatidylcholine. In certain embodiments, the lecithin is present in liposomes, micelles, liquid crystals, or other configurations. The composition can take the form of a gel, a cream, a lotion, an ointment, a solution, a solid “stick,” etc., that can be rubbed or sprayed onto the skin. Other aspects of the present invention are generally directed to methods of making or using such compositions, methods of promoting such compositions, kits including such compositions, or the like.
