endothelial cells and is involved in the angiogenesis process. Taking advantage of functionalities and stereodiversities of sugar derivatives, the design and the synthesis of carbohydrate based peptidomimetics are here described. One of these compounds (56) demonstrated inhibition of VEGF-A165 binding to NRP-1 (IC50 = 39 μM) and specificity for NRP-1 over VEGF-R2. Biological evaluations were performed
Neuropilin-1(NRP-1)是一种跨膜糖蛋白,可作为V
EGF-A的共受体,在癌症和血管生成内皮细胞中表达,并参与血管生成过程。利用糖衍
生物的功能和立体多样性,本文描述了基于
碳水化合物的拟肽的设计和合成。这些化合物之一(56)表现出对V
EGF-A 165结合NRP-1的抑制作用(IC 50 = 39μM)和对NRP-1的特异性高于V
EGF-R2。通过下游蛋白的激活(AKT和ERK
磷酸化),活力/增殖测定以及抗血管生成能力的体外测量,对人脐静脉内皮细胞(HU
VEC)进行了
生物学评估。
