structures, exploring the potential for inhibitory pharmaceutical interventions. Through various bioinformatics tools, we detected 47900 nsSNPs, particularly K142M, I151N, M179R, S184L, L189P, and C321R, which were found to be the most deleterious variants, decreasing the protein stability. These drugs (Sapropterin, Azelaic Acid, Menobenzone, Levodopda, Mequinol, Arbutin, Hexylresorcinol, Artenimol, Alloin

Non-hydroquinone topical medications: retinoic acid, tranexamic acid, kojic acid, mequinol, arbutin, licorice extract, niacinamide, etc., most of which are also tyrosinase inhibitors. Tranexamic acid, also known as aminomethylbenzoic acid, is clinically used

, a punctate melanocyte pattern appeared that was similar to the pattern induced by arbutin or Mequinol (MQ). The EFSC had no effect on the melanocytes of zebrafish larvae. It was discovered that WFSC did not show a stable inhibitory effect until it was extracted 1 month later. These results suggest that the opposite effects of Cuscuta chinensis seeds were caused by the extraction methods and that time has

Mequinol 2%/tretinoin 0.01% solution: an effective and safe alternative to hydroquinone 3% in the treatment of solar lentigines. A new topical solution containing 4-hydroxyanisole (mequinol) 2%/tretinoin 0.01% (Solagé) was compared with its active components, its vehicle, and hydroquinone (HQ) 3% in the treatment of solar lentigines. In a randomized, parallel-group, double-masked study, 216 subjects applied the treatments twice daily for 16 weeks and were followed up for a further 24 weeks. A significantly higher proportion (P < or = .05) of subjects achieved clinical success with mequinol 2%/tretinoin 0.01% compared with HQ 3% as measured by both the lesional pigmentation on the forearm and the physician global assessment at the end of treatment. The proportion of subjects achieving

Analytic quantification of the bleaching effect of a 4-hydroxyanisole-tretinoin combination on actinic lentigines. Solar lentigines represent a common feature of photoaging, particularly on the back of the hands. Bleaching agents are usually proposed to lighten the shade of the lesions. The study was randomized and designed to assess the effect of a bleaching solution containing 2% mequinol (4

The combination of 2% 4-hydroxyanisole (Mequinol) and 0.01% tretinoin is effective in improving the appearance of solar lentigines and related hyperpigmented lesions in two double-blind multicenter clinical studies. Solar lentigines are a chronic condition of the aging population resulting from years of cumulative sun exposure. A topical treatment that is both safe and effective would be welcome and useful. Combinations of therapeutic agents are often used and allow synergy of mechanisms with tolerability. A tyrosinase inhibitor in use in Europe, 4-hydroxyanisole (Mequinol), and the retinoid tretinoin have been used singly as depigmenting agents. The efficacy and safety of the combination product of 2% 4-hydroxyanisole (4HA [mequinol]) /0.01% tretinoin solution (tradename Solagé) were evaluated

of these conditions is unknown. Therapies for melasma and PIH target various points during the cycle of melanin production and degradation. Therapies for these conditions include topical agents and resurfacing procedures. Hydroquinone remains the gold standard of topical agents. Other efficacious agents include kojic acid, azelaic acid, mequinol, and retinoids. Cosmeceutical agents include licorice, arbutin, soy, N

discoloration. Depigmenting agents target different steps in the production of melanin, most commonly inhibiting tyrosinase. These agents include hydroquinone, azelaic acid, kojic acid, arbutin, and certain licorice (glycyrrhiza) extracts. Other agents include retinoids, mequinol, ascorbic acid (vitamin C), niacinamide, N-acetyl glucosamine, and soy, and these products depigment by different mechanisms
