Reaction conditions for the synthesis of thioamide, amidoxime, and N-substituted amidine analogs of the peptide bond are described. Several new amidine analogs of the chemotactic peptide f-Met-Leu-Phe-OR were synthesized using the thioamides as precursors. The assignment of the E/Z configuration was accomplished by nuclear magnetic resonance. The biological activity of these analogs is briefly described.
合成硫酰胺、酰肟和肽键的N-取代酰胺类似物的反应条件已描述。使用硫酰胺作为前体合成了几种新的趋化肽f-Met-Leu-Phe-OR的酰胺类似物。通过核磁共振完成了E/Z构型的确定。简要描述了这些类似物的生物活性。
