IC50: 130, 23, and 18 nM for VEGFR1, 2, and 3, respectively

AAL-993 is a VEGF receptor inhibitor.

A key pro-angiogenic cytokine released by tumor is vascular endothelial growth factor (VEGF). The angiogenic activity of the VEGF family of proteins is mediated by two high affinity receptors, VEGFR-1 and VEGFR-2 located on vascular endothelial cells.

In vitro: AAL-993 was found to be a highly potent and selective inhibitor of the recombinant VEGFR-2 and VEGFR-3 kinases. At 3- to 5-fold higher concentration, AAL-993 also inhibited VEGFR-1 and, although it possessed some activity against other members of the PDGFR kinase family at submicromolar concentrations, AAL-993 did not significantly inhibit any of the other kinases tested at concentrations

In vivo: Animal efficacy study found that AAL-993 was able to potently inhibit VEGF-induced angiogenesis in an implant model, with ED50 values of 7 mg/kg. Moreover, in a mouse orthotopic model of melanoma, AAL-993 could potently inhibit both the growth of the primary tumor as well as the formation of spontaneous peripheral metastases [1].

Clinical trial: So far, no clinical study has been conducted.
