The inhibition of tyrosinase (Ty, EC 1.14.18.1) represents an efficient strategy of decreasing melanogenesis and skin hyperpigmentation. A combination of crystallographic and docking studies on two different tyrosinases, that from Bacillus megaterium (TyBm) and that from a mushroom (TyM), has contributed to increasing our knowledge about their structural information and translating that information
抑制酪氨酸酶(Ty,EC 1.14.18.1)代表了减少黑色素生成和皮肤色素沉着的有效策略。两种不同酪氨酸酶的结晶学和对接研究的结合,来自巨大芽孢杆菌(TyBm)和来自蘑菇(TyM)的酪氨酸酶,有助于增加我们对它们的结构信息的了解,并将该信息转化为最易吸毒的人类Ty(TyH) )同工酶。特别是,我们设计并合成了一系列1-(4-氟苄基)哌嗪和1-(4-氟苄基)哌啶衍生物,它们在微摩尔范围内对TyM表现出抑制活性,并且比参考化合物曲酸具有更高的效价。具有抑制剂3(IC 50的TyBm的晶体结构解决了25.11μM的最大分子量和16(IC 50值为5.25μM)的问题,证实了计算机研究假设的结合态,并揭示了抑制剂识别结合的主要分子决定因素。
