Ten new 2(4-hydroxy-3-benzoyl) benzamide-5-phenyl-1,3,4-oxadiazole derivatives () were synthesized by coupling 3-benzoyl-4-hydroxybenzoic acid ( with 2-amino-5-phenyl-1,3,4-oxadiazoles (). The structures of these compounds were confirmed by IR, H, C NMR, and mass spectra, and also by elemental analyses. The anti-inflammatory activity of the compounds were investigated by screening them against human
通过将3-苯甲酰基-4-羟基苯甲酸(5)与2-氨基偶联,合成了十个新的2(4-羟基-3-苯甲酰基)苯甲酰胺-5-苯基-1,3,4-恶二唑衍生物(10a-j)。 -5-苯基-1,3,4-恶二唑(9a-j)。这些化合物的结构通过IR,1 H,13 C NMR和质谱以及元素分析确认。通过体外筛选化合物对抗人红细胞(HRBC)来研究化合物10a-j的抗炎活性。结果表明,在该系列中,具有羟基取代基的化合物10j,特别是在与恶二唑环的第5个碳原子连接的苯环的邻位上,与对照相比具有显着的膜稳定活性。进一步,进行了体内鸡绒膜尿囊膜(CAM)和大鼠角膜抗血管生成测定,以评估化合物10j对内皮细胞迁移的影响。这证实了化合物10j抑制内皮细胞的增殖。抗炎研究发现了角叉菜胶诱发的大鼠后爪水肿的改善。进一步的体内和计算机模拟方法揭示了炎症标记酶环氧合酶2(Cox-2)和髓过氧化物酶(MPO)的抑制作用。研究报告说,

Piperine is a component of pepper which has earlier been reported as anticancer active compound. This work is emphasized on the design and synthesis of new hybrid piperine analogs by coupling piperine with the amine group of oxadiazoles and thiadiazoles. The new series of twelve piperine analogs was been tested for in vitro anti-proliferative activity using sulforhodamine B (SRB) assay test against MCF-7, PC-3, and HeLa cell lines. Among the twelve synthesised molecules piperine derivative with oxadiazole baring hydroxyl group (3) exhibits the higher activity against MCF-7 cell line than the reference drug Adriamycin and also displays the highest binding energy in the in silico studies. The other analogs are moderately active.
