ALK/IGF1R inhibitor Usage And Synthesis

Uses

AZD3463, is a novel ALK/IGF1R dual Inhibitor, having the ability of overcoming multiple mechanisms of acquired resistance to Crizotinib (C785000).

Definition

ChEBI: AZD3463 is a member of the class of indoles that is 1H-indole substituted by a 2-[4-(4-aminopiperidin-1-yl)-2-methoxyanilino]-5-chloropyrimidin-4-yl group at position 3. It is an orally bioavailable dual inhibitor of ALK and IGF1R with Ki value of 0.75 nM for ALK. It has a role as an apoptosis inducer, an antineoplastic agent, an EC 2.7.10.1 (receptor protein-tyrosine kinase) inhibitor and an autophagy inducer. It is a member of indoles, an aminopiperidine, a monomethoxybenzene, an aminopyrimidine, a secondary amino compound, a tertiary amino compound and an organochlorine compound.

Biological Activity

azd3463 is a novel orally bioavailable alk/igf1r inhibitor with ki value of 0.75 nm. alk expression is largely restricted to neurons and upregulated in neuroblastoma. activated alk has been shown to promote cell survival and growth. high alk expression or mutations in the alk gene correlates with adverse outcomes in neuroblastoma. therefore, alk receptor tyrosine kinase is an important therapeutic target for drug development against neuroblastoma [1].

in vitro

azd3463 (5, 10, 20, and 50 μm) effectively inhibited the proliferation of neuroblastoma cell lines with wild type alk (wt) and alk activating mutations (f1174l and d1091n) via targeting the alk-mediated pi3k/akt/mtor pathway and ultimately induced apoptosis and autophagy in vitro. moreover, azd3463 (1 μm) significantly enhanced the cytotoxic effects of doxorubicin (1 μm) on neuroblastoma cells [1]. azd3463 simultaneously inhibited stat3 and akt to augment the cytotoxic effects of temozolomide and further reduce cell growth [2].

in vivo

azd3463 (15 mg/kg, i.p. injection) showed significant therapeutic efficacy on the growth of the neuroblastoma tumors with wt and f1174l oncogenic mutant alk in orthotopic xenograft mouse models [1].
