Several 1,3,4-trisubstituted pyrazole derivatives were synthesized and screened for their cytotoxic effect in a primary 3 tumor cell line test at 10−4 M drug concentration. Compounds 19 and 20 reduced the growth of one or more of these cell lines to less than 32% and escalated up to evaluation in the full panel of 60 human tumor cell lines at a minimum of 5 concentrations at 10 fold dilutions. Compound N′-(1-1-[4-nitrophenyl]-3-phenyl-1H-pyrazol-4-yl}methylene)-2-chlorobenzohydrazide 19 proved to be the most active of these derivatives with full panel median growth inhibition (GI50), total growth concentration (TGI) and median lethal concentration (LC50) mean graph mid-point (MG-MID) of 3.79, 12.5 and 51.5 μM, respectively. In addition, compounds 19, 39, 40, 41, 43, 45, 47 were tested for their antiangiogenic properties by testing their ability to inhibit human umbilical vein endothelial cells (HUVECs) proliferation, cord formation and migration in response to chemoattractant. 3-Acetyl-2-(1-(4-nitrophenyl)-3-phenylpyrazol-4-yl)-5-(4-pyridyl)-1,3,4-oxadiazoline 39 showed significant antiangiogenic profile at non-cytotoxic doses, with HUVEC proliferation inhibition IC50 of 7.60 μM, chemotaxis IC50 of 0.86 μM and was superior to the reference celecoxib 2 in both tests. Furthermore, in contrary to the references TNP-470 and celecoxib, all the tested compounds interfered with the migratory function of HUVECs in response to vascular endothelium growth factor (VEGF) rather than the endothelial cells proliferation.
合成了几种1,3,4-三取代吡唑衍生物,并在10-4 M药物浓度下对其在初级3肿瘤细胞系测试中的细胞毒性效应进行了筛选。化合物19和20使得一个或多个细胞系的生长减少到不到32%,并在至少5个浓度下以10倍稀释的方式在60个人类肿瘤细胞系的完整面板中进行了评估。化合物N′-(1-1-[4-硝基苯基]-3-苯基-1H-吡唑-4-基}亚甲基)-2-氯苯甲酰肼19证明了这些衍生物中最活跃的,其在全面板中的中位生长抑制(GI50)、总生长浓度(TGI)和中位致死浓度(LC50)平均图表中点(MG-MID)分别为3.79、12.5和51.5 μM。此外,化合物19、39、40、41、43、45、47通过测试其抑制人脐静脉内皮细胞(HUVECs)增殖、索形成和迁移的能力来测试其抗血管生成性质。3-乙酰基-2-(1-(4-硝基苯基)-3-苯基吡唑-4-基)-5-(4-吡啶基)-1,3,4-氧二氮杂环烯39在非细胞毒性剂量下显示出显著的抗血管生成特征,HUVEC增殖抑制IC50为7.60 μM,趋化IC50为0.86 μM,并且在两个测试中均优于参考塞来昔布2。此外,与参考TNP-470和塞来昔布相反,所有测试的化合物都干扰了HUVECs在血管内皮生长因子(VEGF)响应中的迁移功能,而不是内皮细胞增殖。
