This paper reports the preparation of new benzoyl and/or benzyl substituted 1,2,3-triazole derivatives and their pharmacological evaluation as potential BK channel openers, as a part of a research program which hypothesized a pharmacophoric structure containing the 1,2,3-triazole ring. The synthetic procedures consist essentially with the 1,3-dipolar cycloaddition of aryl or benzyl azides to the asymmetric
本文报告了新的苯甲酰基和/或苄基取代的1,2,3-三唑衍生物的制备及其作为潜在的BK通道开放剂的药理评价,作为一项研究程序的一部分,该程序假设了含有1,2,3的药效团结构-三唑环。合成方法主要由芳基或苄基叠氮化物的1,3-偶极环加成到不对称炔炔苯甲酰基乙炔上而得到的所希望的4-苯甲酰基-1,2,3-三唑异构体的量更大。药理结果表明1-(2-羟基苄基)-4-苄基-1H-1,2,3-三唑具有高的血管松弛活性,涉及BK通道的开放。因此,关于该药效团结构的构效关系证实了在芳香环邻位的酚功能的有用性,并暗示了带有苄基取代基的1,2,3-三唑模型。另外,相对于具有更高共平面构象趋势的苯基,这样的取代基显得更柔韧并且能够采取不同的构象。
