Coumarin moiety has garnered momentous attention especially in the design of compounds with significant biological activities. In this work, a series of 3-substituted coumarin derivatives 6a-6l were synthesized and fully characterized. Most of the compounds could obviously inhibit the activity of cyclooxygenase-1 (COX-1) at the concentration of 10 µM. Besides, 6h and 6l exhibited highest inhibitory
香豆素部分已经引起了广泛的关注,特别是在具有显着生物学活性的化合物的设计中。在这项工作中,合成并充分表征了一系列3-取代的香豆素衍生物6a-6l。在10 µM的浓度下,大多数化合物都能明显抑制环氧合酶1(COX-1)的活性。此外,6h和6l对COX-2的抑制作用最高,抑制率分别为33.48%和35.71%。还讨论了详细的结构-活性关系(SAR)。在体内研究中,6b,6i和6l可以以20 mg / kg的剂量显着抑制小鼠体内由二甲苯引起的耳肿。特别地,在10mg / kg的剂量下6l似乎是最有效的化合物,表现出与消炎痛相当的有利的抗炎活性。
