substance P analogue with the use of solid-phase peptide synthesis. A similar intramolecular reductive amination strategy was used to synthesize a substance P analogue having only Phe7 constrained, and the original 3-phenylproline was converted into a substance P analogue having only Phe8 constrained. All of the analogues were examined for their ability to displace substance P from its NK-1 receptor
已经合成了用于物质P的Phe7-Phe8区的内酰胺基拟肽。该合成使用阳极酰胺氧化来选择性官能化3-苯基脯氨酸衍生物的C5位。所得的脯氨酸衍生物与Cbz保护的苯丙氨酸偶联,并使用分子内还原胺化策略将偶联的材料转化为双环哌嗪酮环骨架。最终结果是二肽构件,将物质P的Phe7-Phe8区的两个拟议的受体结合构型之一嵌入双环骨架中。然后使用固相肽合成将构件转换为受限物质P类似物。使用类似的分子内还原胺化策略合成仅具有Phe7约束的P物质类似物,并且将原始的3-苯基脯氨酸转化为仅具有Phe8约束的P物质类似物。检查所有类似物从其NK-1受体置换P物质的能力。
