We describe the incorporation of a bicyclo[1.1.1]pentane moiety within two known LpPLA2 inhibitors to act as bioisosteric phenyl replacements. An efficient synthesis to the target compounds was enabled with a dichlorocarbene insertion into a bicyclo[1.1.0]butane system being the key transformation. Potency, physicochemical, and X-ray crystallographic data were obtained to compare the known inhibitors
我们描述了在两个已知的LpPLA 2抑制剂中掺入双环[1.1.1]戊烷部分以充当生物等位苯基替代物。通过将二氯卡宾插入双环[1.1.0]丁烷系统是关键的转化,从而能够高效合成目标化合物。获得了效价,理化和X射线晶体学数据,以将已知抑制剂与其生物等排体对等物进行比较,这表明该等排物具有良好的耐受性,并对理化特性产生了积极影响。
