General description

A cell-permeable anthranilamide that acts as a potent VEGFR inhibitor (IC50 = 130, 23, and 18 nM against VEGFR-1, -2, and -3, respectively; IC50 = 1.24 nM against VEGF-induced human VEGFR-2 phosphorylation in CHO cells) by targeting the ATP-binding site of VEGFR in its inactive "DFG-out" conformation and effectively suppresses tumor growths (50 to 100 mg/kg; p.o.) via its anti-angiogenesis activity in mice and rats in vivo, while inhibiting c-kit, CSF-1R/c-Fms, PDGFR-β, and c-Abl only at higher concentrations (IC50 = 236, 380, 640, and 2820 nM, respectively). AAL933 and two other VEGFR inhibitors, KRN633 and SU5416, are also shown to inhibit hypoxia-induced HIF-1α expression (by <90% at 30 M) and transcription activation. Unlike KRN633 and SU5416, AAL933 prevents only hypoxia-induced Erk, but not Akt, phosphorylation in HeLa cells.

Reported to be orally available in mice (Conc. in plasma = 9.5, 4.7, 1.5, and 1.1 M, respectively, 0.5 h, 1 h, 1.5 h, and 2 h after p.o. dosage of 50 mg/kg), rats, and dogs, and effectively suppress tumor growths (50 to 100 mg/kg; p.o.) via its anti-angiogenesis activity in various cancer models in vivo, including murine melanoma B16-BL6, rat mammary adenocarcinoma BN472, as well as human prostate cancer DU145-grafted mice in vivo. AAL933 and two other VEGFR inhibitors, KRN633 and SU5416, are also shown to inhibit hypoxia- (1% O2) induced HIF-1α expression (by <90% at 30 M) and transcription activation (IC50 = 6.53, 3.79, and 8.24 M, respectively, by AAL933, KRN633, and SU5416 in HeLa-HRE-Luc reporter assays). However, unlike KRN633 and SU5416, AAL933 prevents only hypoxia-induced Erk, but not Akt, phosphorylation in HeLa cells.

The dynamic nanoscale organization of cell surface receptors plays an important role in signaling. We determine this organization and its relation to activation of VEGF receptor-2 (VEGFR-2), a critical receptor tyrosine kinase in endothelial cells (ECs), by combining single-molecule imaging
