Platelet-derived growth factor (PDGF) and its receptor PDGFR are required for tumor growth and angiogenesis, so disruption of the PDGFâPDGFR interaction should lead to starvation of tumors and reduction of tumor growth. Potent PDGF antagonists have been discovered through the synthesis of a series of calix[4]arene-based compounds that are designed to bind to the three-loop region of PDGF. The effect of lower-rim alkylation, linker and number of interacting head groups on the calix[4]arene scaffold on PDGF affinity and cellular activity has been investigated.
血小板衍生生长因子(PDGF)及其受体PDGFR对于肿瘤生长和血管生成是必需的,因此,破坏PDGF与PDGFR的相互作用应能导致肿瘤饥饿并减少肿瘤生长。通过合成一系列设计为结合PDGF三环区域的基于calix[4]arene的化合物,发现了强效的PDGF拮抗剂。研究了下缘烷基化、连接剂和相互作用头基数量对calix[4]arene骨架在PDGF亲和力和细胞活性上的影响。
