were successfully applied in the synthesis of two novel neurotensin receptor ligands. Both isomers showed high affinity for the human NTS2 receptor with Ki values in the nanomolar range. Interestingly, subtype selectivity strongly depends on the configuration of the peptide in position 11. Isomer (11R)-3 displayed an excellent preference for NTS2 compared to NTS1.
一个由Fmoc保护的3-芳基酪氨酸的小文库是通过自由基芳基化创建的。新的构建基块已成功应用于两种新型神经降压素受体配体的合成。两种异构体均以纳摩尔范围的K i值显示出对人NTS2受体的高度亲和力。有趣的是,亚型的选择性很大程度上取决于11位肽的构型。与NTS1相比,异构体(11 R)-3对NTS2表现出极好的偏好。
