Comment: Pegdinetanib (BMS-844203) was a clinical lead vascular endothelial growth factor receptor 2 (VEGFR2) inhibitor. It is an engineered, affinity-matured peptide derived from human fibronectin type III (FN3: residues 1424-1516) that binds to VEGFR2 [1,3]. The peptide is conjugated with polyethylene glycol (PEG) to increase its molecular size above the threshold for kidney-mediated clearance, and this effectively extends its circulating half-life [5]. Pegdinetanib was investigated for anti-angiogenic activity and its potential to inhibit vascularisation in tumours [2,4]. Pegdinetanib is an example of a peptide-based therapeutic that has utilised a novel scaffold (FN3) as an alternative to antigen receptors (antibodies).
Note that the PubChem CID for pegdinetanib (86278317) represents only the PEG moiety and not the entire peptide conjugate.
