The chiral isomers of the two potent simplified RTX-based vanilloids, compounds 2 and 3, were synthesized employing highly enantioselective PTC alkylation and evaluated as hTRPV1 ligands. The analysis indicated that the R-isomer was the eutomer in binding affinity and functional activity. The agonism of compound 2R was comparable to that of RTX. Docking analysis of the chiral isomers of 3 suggested the basis for its stereospecific activity and the binding mode of 3R.
两种有效简化的 RTX 香草素手性异构体,化合物 2 和 3,采用高度对映选择性 PTC 烷基化合成,并作为 hTRPV1 配体进行了评估。分析表明,R-异构体在结合亲和力和功能活性方面是优势对映体。化合物 2R 的激动作用与 RTX 相当。3 的对映异构体的对接分析表明了其立体特异性活性的基础和 3R 的结合模式。
