VEGFR Tyrosine Kinase Inhibitor VI, AAL-993-CAS 269390-77-4-Calbiochem

半岛bd体育手机客户端 说明

一般描述

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 ratsin 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 modelsin vivo, including murine melanoma B16-BL6, rat mammary adenocarcinoma BN472, as well as human prostate cancer DU145-grafted micein 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.
