Arbutin (beta-Arbutin) is a competitive inhibitor of tyrosinase in melanocytes, with K_i^app values of 1.42 mM for monophenolase; 0.9 mM for diphenolase. Arbutin is also used as depigmenting agents^[1]. Arbutin is a natural polyphenol isolated from the bearberry plant Arctostaphylos uvaursi, possesses with anti-oxidant, anti-inflammatory and anti-tumor properties^[2][3]. IC50 & Target: Tyrosinase^[1] In Vitro: Arbutin (0.3-5.4 mM; 24 hours, 48 hours, 72 hours; B16 murine melanoma cells) inhibites the viability of B16 murine melanoma cells in a time-and dose-dependent manner^[2].
Arbutin (1.4-5.4 mM; 24 hours) increases the apoptosis rate of B16 murine melanoma cell of treatment at a dose of 5.4 mM^[2]. In Vivo: Arbutin (50 mg/kg, 100 mg/kg; oral administration; every day; for 17 days; male C57BL/6 mice) pretreatment exhibits markedly protective effects on ISO-induced cardiac hypertrophy in mice^[3].
