We recently presented that compounds 4a–b moderately inhibited leukotriene (LT) formation in human neutrophils. For structural derivatization of 4a–b, novel thirty-six title compounds were synthesized and led to more potent inhibition of LT biosynthesis in activated human neutrophils exemplified by compounds 15, 27–30, 32–37, 41, 42 with IC50 values in the range of 1.6–3.5 μM. Moreover, compounds 32
我们最近提出,化合物4a – b适度抑制人类嗜中性白细胞中白三烯(LT)的形成。对于结构衍生4A - b,合成并导致在由例示化合物活化人中性粒细胞LT的生物合成更有效抑制新颖36标题化合物15,27-30,32-37,41,42与IC 50个值在范围为1.6–3.5μM。此外,化合物32,35,42,43和44显示出对血小板COX-1活性的显着抑制,IC 50分别为2.5、0.041、0.3、0.9和0.014μM,从而导致了双重作用的抑制剂。基于它们在细胞环境中的高效力,这些简单的吡唑-3-丙酸衍生物可能在设计更有效的化合物中具有潜力,可用于治疗炎症和过敏性疾病。
