3-triazole derivatives as CB1 receptor antagonists. The design, synthesis and biological evaluation of N1 and N2 substituted 1,2,3-trizoles are described. The N2 substituted, symmetrical 1,2,3-triazoles are more potent ligands than the unsymmetrical analogues. The in vitro activity of these triazoles is further improved by inserting a methylene group between the central core and the carbonyl side chain
这封信报道了新的1,2,3-三唑衍生物作为CB1受体拮抗剂的新进入。描述了N 1和N 2取代的1,2,3-三唑的设计,合成和生物学评估。所述Ñ 2取代的,对称的1,2,3-三唑是更有效的配体比非对称的类似物。通过在中心核和羰基侧链之间插入一个亚甲基,可以进一步提高这些三唑的体外活性。在该系列中制备的最有效的拮抗剂(IC 50 <20 nM)是含有苄基酰胺的三唑。这些三唑在CB1和CB2受体之间也显示出极好的选择性(CB2的IC 50 > 10μM; CB2 / CB1> 1000)。
