常見問題列表
生物活性
(R)-Trolox 是水溶性維生素 E 類似物，是一種競爭性酪氨酸酶抑制劑，Ki 值為 0.83 mM，ID50 值為 1.88 mM。(R)-Trolox 具有比 (S) 對映異構(gòu)體更強的酪氨酸酶親和力 (Ki 值為 0.61 mM)。體外研究
As compared to the control containing no inhibitor, DMSO suppresses the tyrosinase activity at tested levels, 100 and 200 μL in a total volume of 3.0 mL. The inhibition of DMSO on the mushroom tyrosinase is dosedependent. Additions of DMSO at the two levels in the tyrosinase digests containing (R)-Trolox ((R)-HTCCA) results in further inhibitions of the tyrosinase activity. The influence of the DMSO on the inhibitory effects of (R)-Trolox against the tyrosinase is also dose-dependent.
