AZD-3463 (AZD3463) is a novel, potent and selective ALK/IGF1R inhibitor with potential anticancer activity. It is capable of overcoming several ways in which crizotinib-induced acquired resistance occurs. By causing apoptosis and overcoming crizotinib resistance, AZD3463 prevents the growth of neuroblastomas. In orthotopic xenograft mouse models, AZD3463 demonstrated a strong antitumor efficacy against neuroblastoma tumors containing WT and F1174L oncogenic mutant ALK.
IGF-1R; ALK (Ki = 0.75 nM)
AZD3463 exhibits strong effects in preclinical models driven by ALK as well as in a range of crizotinib-resistant models. As evidenced by its capacity to reduce ALK autophosphorylation in tumor cell lines carrying ALK fusions, such as DEL (ALCL NPM-ALK), H3122 (NSCLC EML4-ALK), and H2228 (NSCLC EML4-ALK), AZD3463 inhibits ALK in cells. ALK inhibition is linked to disruptions in the ERK, AKT, and STAT3 signaling cascades, which specifically inhibit the proliferation of ALK-fusion-containing cell lines in vitro. AZD3463 continues to exhibit strong activity against several clinically significant crizotinib-resistant mutations, such as the gatekeeper mutant L1196M, which exhibits in vitro and in vivo equivalent potency to wild type ALK in BAF3 cell lines containing EML4-ALK. In order to evaluate AZD3463's potential to circumvent additional resistance mechanisms, antiproliferative activity is evaluated in both a patient-derived crizotinib relapsed model and multiple independently derived in vitro crizotinib resistant cell lines derived from H3122 cells. The L1196M gatekeeper and T115Ins mutations, ALK amplification, and/or secondary drivers like EGFR and IGF1R are just a few of the resistance mechanisms present in these resistant cell lines. In vitro, AZD3463 maintains its antiproliferative efficacy in 10 of the 12 acquired resistance models, four times that of the parental H3122 cells.
AZD3463 exhibits the capacity to inhibit pALK in xenograft tumors in vivo in a dose-dependent manner, leading to either stasis (H3122) or regression (DEL, H2228).
ZD-3463 is an ALK/IGF1R inhibitor that circumvents a number of mechanisms involved in the development of crizotinib resistance.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
