2-(p-(Substituted)phenyl)-5-(3-(4-ethylpiperazine-1-yl) propionamido)benzoxazole derivatives (B7-B11) were designed, synthesized, and their antimicrobial activities were determined by the microdilution method. The novel benzoxazole compounds were characterized using FTIR, 1H NMR, and 13C NMR spectroscopy, mass spectroscopy, and elemental analysis. B7 and B11 showed promising activity against P. aeruginosa isolate at
本研究设计、合成了五种新的2-(对-(取代)苯基)-5-(3-(4-乙基哌嗪-1-基)丙酰胺基)苯并恶唑衍生物( B7 - B11 ),并对其抗菌活性进行了研究。微量稀释法测定。使用 FTIR、1 H NMR 和13 C NMR 光谱、质谱和元素分析对新型苯并恶唑化合物进行了表征。B7和B11对铜绿假单胞菌显示出有希望的活性与参考药物相比,分离浓度为 16 µg/mL。使用密度泛函理论 (DFT) 和 B3LYP/6–311G(d,p) 水平对五种基态化合物进行了量子力学计算。还对化合物的分子对接研究进行了 DNA 促旋酶与环丙沙星 (PDB: 2XCT) 的复杂结构,观察到结合姿势与环丙沙星相似。化合物的理论 ADME 曲线符合 Lipinski 和其他限制规则。
Synthesis, molecular docking and antimicrobial evaluation of novel benzoxazole derivatives
zole derivatives has been designed and synthesized based on the highly conserved active site of VEGFR-2. Several title compounds exhibited selective inhibitory activities against VEGFR-2 than EGFR kinases, which also displayed selective anti-proliferation potency against the HUVEC and HepG2 than the A549 and MDA-MB-231 cancer cell lines. The newlysynthesized compounds were evaluated for anti-angiogenesis

agents with previously reported imidazole kinase inhibitors as a lead compound. A library of 29 compounds was synthesized. Several title compounds exhibited selective inhibitory activities against vascular endothelial growth factor receptor 2 (VEGFR‐2) over epidermal growth factor receptor (EGFR) kinase; these compounds also displayed selective and potent antiproliferative activity against three cancer
我们着手进行结构优化运动,旨在发现以先前报道的咪唑激酶抑制剂为先导化合物的新型抗血管生成剂。合成了29种化合物的文库。与表皮生长因子受体(EGFR)激酶相比,几种标题化合物对血管内皮生长因子受体2(VEGFR-2)表现出选择性抑制活性。这些化合物还显示出对三种癌细胞的选择性和有效的抗增殖活性。通过雏鸡绒膜尿囊膜(CAM)分析评估了新合成的化合物的抗血管生成活性。其中1-(2-(2-氯苯基)苯并[ d ]恶唑-5-基)-3-(4-(三氟甲氧基)苯基)脲(化合物5 n)表现出最强的抗血管生成能力,有效的细胞毒性活性(体外针对人脐静脉内皮细胞(HUVEC),H1975,A549和HeLa细胞系,其IC 50值分别为8.46、1.40、7.61和0.28μ米),和VEGFR-2激酶抑制的可接受的水平(IC 50 = 0.25μ米)。分子对接分析显示5 n是VEGFR-2激酶的II型抑制剂。总的来说
