ALK-IN-12 is a highly potent and orally active inhibitor of anaplastic lymphoma kinase (ALK), demonstrating an exceptional IC50 value of 0.18 nM. Additionally, ALK-IN-12 displays inhibitory activity against insulin-like growth factor 1 receptor (IGF1R) and insulin receptor (InsR), with IC50 values of 20.3 nM and 90.6 nM, respectively. Notably, its antitumor effects have been observed, making it a promising compound for targeted cancer therapy.

ALK-IN-12 (compound 11e) effectively inhibits viability of the Karpas-299 ALCL cell line with an IC 50 of 28.3 nM[1].

ALK-IN-12 (10-50 mg/kg; orally; once daily for 13 consecutive days) shows dose-dependent antitumor activity[1]. ALK-IN-12 (3 mg/kg; i.v.; 6-8 week old female CD rats ) treatment shows AUC 0-∞ , CL, t 1/2 and V ss are 3039 ng?h/mL, 0.91 h?kg, 6.6 hours and 6.12 L/kg, respectively[1]. ALK-IN-12 (10 mg/kg; p.o.; 6-8 week old female CD rats) treatment shows C max , AUC 0-∞ , t max , t 1/2 and F are 3254 ng/mL, 4056 ng?h/mL, 6.0 hours, 12.5 hours and 39%, respectively[1]. Animal Model: Eight- to 10-week old female SCID/beige mice (Karpas-299 xenograft mouse model expressing the NPM-ALK fusion)[1]Dosage: 10-50 mg/kg Administration: Orally; once daily for 13 consecutive days Result: Dose-dependent antitumor activity. Led to tumor stasis (50 mg/kg dose).
