The synthesis of N‐[5‐(2‐phenoxyphenyl)‐1, 3, 4‐oxadiazole‐2‐yl]‐N′‐phenylurea derivatives is reported. The structures of these compounds are supported by their IR, 1H‐NMR and mass spectra. Conformational analysis and superimposition of energy minima conformers of these compounds on L‐365, 260, a known 3‐ureido‐1, 4‐benzodiazepine CCK‐B antagonist, showed that the aromatic rings fell in the same contour
报道了N-[5-(2-苯氧基苯基)-1, 3, 4-恶二唑-2-基]-N'-苯基脲衍生物的合成。这些化合物的结构得到了它们的 IR、1H NMR 和质谱的支持。这些化合物的构象分析和能量最小值构象异构体在 L-365、260(一种已知的 3-脲基-1, 4-苯二氮卓 CCK-B 拮抗剂)上的叠加表明,芳环落在相同的轮廓上。与对照组相比,合成化合物的吗啡镇痛增强评价表明化合物8a、8c、8h-8j、8l、8o具有显着效果。
