Mequinol (Leucobasal) is a synthetic derivate of hydroquinone and depigmenting agent. Although the exact mechanism of the depigmenting effects of mequinol remains unclear, it may exert its effect by oxidation of tyrosinase to cytotoxic products in melanocytes.

Product Introduction

Bioactivity

Description	Mequinol (Leucobasal) is a synthetic derivate of hydroquinone and depigmenting agent. Although the exact mechanism of the depigmenting effects of mequinol remains unclear, it may exert its effect by oxidation of tyrosinase to cytotoxic products in melanocytes.
In vivo	Leucobasal is commercially available in the United States as a 2% topical formulation for skin lightening purposes. It acts as a substrate for tyrosinase, thereby functioning as a competitive inhibitor of melanin precursor formation. When diluted in a medium or applied topically on the stratum corneum (RE), Leucobasal leads to reduced pigmentation by decreasing melanin in differentiated keratinocytes and melanocytes. This results in a lowered count of dopa-positive melanocytes induced by Leucobasal.
Synonyms	Leucobasal, 4-Methoxyphenol, 4-Hydroxyanisole

For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments

A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent

DMSO+30% PEG300+5% Tween 80+60% Saline/PBS/ddH₂O. So your working solution concentration is 2 mg/mL。

Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO TargetMol | reagent

(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.

Preparation method for in vivo formula: Take 50 μL DMSO TargetMol | reagent
