promising candidates as new angiogenesis modulators. Based on the minimal four amino acid sequence of peptidic ligands known to bind NRP-1, we describe here the design, synthesis and biological evaluation of series of original sugar-based peptidomimetics using a C-glycosyl compound, derived from d-gulonolactone, as a scaffold, which was functionalized with side chains of the amino-acids arginine, and tryptophane
Neuropilin-1(NRP-1)是VEGFR 165的共受体,干扰VEGF 165与NRP-1结合的分子似乎有望成为新的血管生成调节剂。基于已知与NRP-1结合的肽配体的最少四个氨基酸序列,我们在这里描述了一系列使用衍生自d-古洛内酯的C-糖基化合物作为糖基拟肽的一系列原始模拟物的设计,合成和生物学评估。一个支架,它被氨基酸精氨酸和色氨酸或苏氨酸的侧链功能化。在100μM下,所有化合物均对NRP-1表现出弱亲和力,最有效的是双胍基化的化合物32(IC 50 = 92μM),可以将其视为新的NRP-1非肽配体。
