(R)-Trolox 是水溶性维生素 E 类似物，是一种竞争性酪氨酸酶抑制剂，Ki 值为 0.83 mM，ID50 值为 1.88 mM。(R)-Trolox 具有比 (S) 对映异构体更强的酪氨酸酶亲和力 (Ki 值为 0.61 mM)。
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.
