different analogues of the native ligand have been synthesized and evaluated. Compounds 1‐3 possess the general formula HCO‐Met‐Leu‐Xaa‐OMe with Xaa = N‐benzylglycine, N‐benzylphenylalanine, and α,α‐dibenzylglycine, respectively. In the analogue 4 the constraint at the C‐terminus has been obtained by incorporating a 2‐oxopiperazine ring, made up of two phenylalanine residues, to replace the native
在一项旨在阐明 HCO-Met-Leu-Phe-OMe (fMLF-OMe) 结构特征的研究项目中,该结构特征控制与 C-末端残基对应的受体的相互作用,天然配体的四种不同类似物具有被合成和评估。化合物 1-3 的通式为 HCO-Met-Leu-Xaa-OMe,其中 Xaa = N-苄基甘氨酸、N-苄基苯丙氨酸和 α, α-二苄基甘氨酸。在类似物 4 中,通过引入由两个苯丙氨酸残基组成的 2-氧代哌嗪环来取代天然的 C-末端 Phe 残基,从而获得了 C-末端的约束。讨论了化学修饰对新类似物活性的影响。
