In our previous study, we designed a series of pyrazole derivatives as novel COX-2 inhibitors. In order to obtain novel dual inhibitors of COX-2 and 5-LOX, herein we designed and synthesized 20 compounds by hybridizing pyrazole with substituted coumarin who was reported to exhibit 5-LOX inhibition to select potent compounds using adequate biological trials sequentially including selective inhibition
在我们先前的研究中,我们设计了一系列吡唑衍生物作为新型COX-2抑制剂。为了获得新型的COX-2和5-LOX双重抑制剂,我们在此设计并合成了20种化合物,方法是将吡唑与取代的香豆素杂交,据报道,该香豆素具有5-LOX抑制作用,并使用包括选择性抑制在内的充分生物学试验依次选择有效的化合物。 COX-2和5-LOX的表达,体外抗增殖,细胞凋亡和细胞周期。其中,最有效的化合物11g( COX-2的IC 50 = 0.23± 0.16μM,5-LOX的IC 50 = 0.87±0.07μM, 针对A549的IC 50 = 4.48±0.57μM)与阳性对照相比具有初步优势。控制塞来昔布( 对于COX-2,IC 50 = 0.41± 0.28μM, 对于A549 ,IC 50 = 7.68± 0.55μM)和Zileuton( 对于5-LOX,IC 50 = 1.35± 0.24μM)。进一步的研
