Usage

General Description

7,8-dimethyl-10-formylmethylisoalloxazine is a chemical compound also known as riboflavin, or vitamin B2. It is a yellow, water-soluble compound that is essential for the metabolism of fats, carbohydrates, and proteins in the body. Riboflavin also plays a key role in energy production and in maintaining healthy red blood cells, skin, and vision. It is commonly found in food sources such as dairy products, eggs, green leafy vegetables, and meat. Riboflavin deficiency can result in a range of health issues, including fatigue, impaired immune function, and skin disorders. Additionally, riboflavin is used as a dietary supplement and as an ingredient in various cosmetic and pharmaceutical products.

Photoirradiation products of flavin derivatives, and the effects of photooxidation on guanine

Photoirradiation in the presence of riboflavin led to guanine oxidation and the formation of imidazolone. Meanwhile, riboflavin itself was degraded by ultraviolet light A (UV-A) and visible light (VIS) radiation, and the end product was lumichrome. VIS radiation in the presence of riboflavin oxidized guanine similarly to UV-A radiation. Although UV-A radiation with lumichrome oxidized guanine, VIS radiation with lumichrome did not. Thus, UV-A radiation with riboflavin can oxidize guanine even if riboflavin is degraded to lumichrome. In contrast, following VIS radiation degradation of riboflavin to lumichrome, VIS radiation with riboflavin is hardly capable of oxidizing guanine. The consequences of riboflavin degradation and guanine photooxidation can be extended to flavin mononucleotide and flavin adenine dinucleotide. In addition, we report advanced synthesis; carboxymethylflavin was obtained by oxidation of formylmethylflavin with chlorite and hydrogen peroxide; lumichrome was obtained by heating of formylmethylflavin in 50% AcOH; lumiflavin was obtained by incubation of formylmethylflavin in 2 M NaOH, followed by isolation by step-by-step concentration.
