molecule vascular endothelial growth factor D (VEGF-D). The mimetics were designed to inhibit dimerization of the receptors (VEGFR-2 and VEGFR-3) by VEGF-D, and thus have the potential to inhibit angiogenesis. To this end, in the previously described cyclic octapeptide CNEESLIC and the cyclic nonapeptide CGNEESLIC inhibitors derived from VEGF-D loop 2, the NEES tetrapeptide residue was replaced by a carbohydrate
环肽-碳水化合物(化合物 1a-c、2、33、34)被设计和合成以充当促血管生成分子血管内皮生长因子 D(VEGF-D)的环 2 的模拟物。模拟物旨在通过 VEGF-D 抑制受体(VEGFR-2 和 VEGFR-3)的二聚化,因此具有抑制血管生成的潜力。为此,在先前描述的环状八肽 CNEESLIC 和衍生自 VEGF-D 环 2 的环状九肽 CGNEESLIC 抑制剂中,NEES 四肽残基被碳水化合物支架取代,该碳水化合物支架在建模研究提出的位置具有氨基酸侧链模拟物。使用 Fmoc 技术连接额外的氨基酸,然后形成环状二硫化物,
