通过自由基芳基化产生Fmoc保护的3-芳基化酪氨酸的小文库。新的结构单元已成功应用于两个新的神经降压素受体配体的合成。两种异构体均显示出对人NTS 2受体的高亲和力,K(i)值在纳摩尔范围内。有趣的是,亚型选择性强烈依赖于11位肽的构型。与NTS 1相比,异构体(11 R)-3显示出对NTS 2的优异偏好。
A small library of Fmoc-protected 3-arylated tyrosines was created by radical arylation. The new building blocks were successfully applied in the synthesis of two novel neurotensin receptor ligands. Both isomers showed high affinity for the human NTS2 receptor with K(i) 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.
