4-бутилрезорцин

4-n-butylresorcinol is a derivative of resorcinol and a potent human tyrosinase inhibitor. It may be used to decrease skin irritation and is also known to inhibit melanin production.

4-Butylresorcinol is considered a potential Cytochrome P450 inhibitor. It can cause hypopigmentation due to its direct inhibition of tyrosinase.

Glycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. Glycerol (5-10%) increases the density of a sample so that the sample will layer at the bottom of a gel′s sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component.

Glutathione reductase IGR) is a crucial flavoenzyme in the antioxidant defense system. Reduced glutathione (GSH) is used by glutathione peroxidase to detoxify hydrogen peroxide and in the process is converted to oxidized glutathione (GSSG). The GSSG is then recycled back to GSH by glutathione reductase (GR) using NADPH that is then converted to NADP+. The regenerated GSH is then available to detoxify more hydrogen peroxide. The enzyme uses FAD as a cofactor. GR and glutathione peroxidase may inhibit lipid peroxidation by functioning as antioxidant enzymes in sperm. Glutathione reductase shares a structural motif with a number of other proteins including aspartyl proteases, citrate synthase, EF hands, hemoglobins, lipocalins, and α/β hydrolases. GR is stimulated by melatonin and is reportedly irreversibly inhibited by a number of oxygen radical generating systems.A sweet tastant for mammals. A glycerol taste receptor binding site specific for glucose has been proposed in drosophila.

The mechanism of action of 4-butylresorcinol depigmentation is through inhibition of tyrosinase and tyrosinase-related protein-1 (TRP-1)^[1].
