chalcone derivatives 1–18, bearing isoxazole moieties were designed and synthesized, and biologically evaluated for their activity on mushroom tyrosinase and melanin synthesis in murine B16 cells. The result indicated that most of prepared compounds 1–18 showed potent activating effect on tyrosinase, especially for 1–2, 4, 6–7, 9 and 15. Among them, compounds 2, 4 and 9 demonstrated the best activity with
一系列新的查耳酮衍生物的1 - 18,轴承异恶唑基部分,设计并合成,和生物学评价其活性对蘑菇酪氨酸酶和鼠B16细胞的黑色素合成。结果表明,大多数制备的化合物的1 - 18对酪氨酸强效的激活作用,特别是对于1 - 2,4,6 - 7,9和15。其中,化合物2,4和9显示出最好的活性,EC 50 = 1.3,2.5和3.0μmol·L-1分别比阳性对照8-甲氧基补骨脂蛋白(8-MOP,EC 50 = 14.8μmol·L -1)好得多;在B16细胞中,所有测试的化合物对黑素生成的活性均强于8-MOP(值为115%)。有趣的是用卤素(取代的衍生物1,2,4,5,7,9)一般是更有效。与8-MOP相比,分别具有3倍和4倍效力的化合物2(463%)和18(438%)被公认为是进一步抗玻璃体药理研究的最有希望的候选药物。
