and synthesized ten NAB (N-(acryloyl)benzamide) derivatives (1a-1j) using the Horner-Wadsworth-Emmons olefination of diethyl (2-benzamido-2-oxoethyl)phosphonate and appropriate benzaldehydes. A mushroom tyrosinase inhibitory assay showed compounds 1a (36.71 ± 2.14% inhibition) and 1j (25.99 ± 2.77% inhibition) inhibited tyrosinase more than the other eight NAB derivatives and kojic acid (21.56 ± 2
酪氨酸酶的靶向已被证明是识别美白皮肤安全,有效和有效的酪氨酸酶抑制剂的最佳方法。我们使用(2-benzamido-2-oxoethyl)膦酸二乙酯和合适的苯甲醛的Horner-Wadsworth-Emmons烯化反应设计并合成了十种NAB(N-(丙烯酰基)苯甲酰胺)衍生物(1a-1j)。蘑菇酪氨酸酶抑制试验显示化合物1a(抑制36.71±2.14%)和1j(抑制25.99±2.77%)抑制酪氨酸酶的作用比其他八种NAB衍生物和曲酸(抑制21.56±2.93%)更大,对接研究表明1a( -6.9 kcal / mol)和1j(-7.5 kcal / mol)对酪氨酸酶的结合亲和力比曲酸(-5.7 kcal / mol)强。在25μM的浓度下,1a和1j对B16F10黑色素瘤细胞无毒,并表现出更强的酪氨酸酶抑制作用(59。比曲酸(抑制50.30%)或熊果苷(400μM抑制41.78%)分别高70%和76
