| Description |
TAE684 (NVP-TAE684) is a potent and selective ALK inhibitor with IC50 of 3 nM in a cell-free assay, 100-fold more sensitive for ALK than InsR. |

TAE684 does not exhibit significant cross-reactivity against other kinases. TAE684 potently inhibits the proliferation of Ba/F3 NPM-ALK cells with IC50 of 3 nM, without affecting the survival of Ba/F3 cells even at 1 μM. TAE684 also inhibits proliferation of NPM-ALK-expressing human ALCL cell lines including Karpas-299 and SU-DHL-1 with IC50 of 2–5 nM. Molecular modeling reveals that L258 may be one of the major kinase-selectivity determinants for TAE684. TAE684 treatment results in a rapid and sustained inhibition of phosphorylation of NPM-ALK. TAE684 induces apoptosis and G1 phase arrest in NPM-ALK-expressing Ba/F3 cells and ALCL patient cell lines. [1] TAE684 markedly overcomes Crizotinib-resistance in H3122 CR cells, harboring the fusion oncogene EML4-ALK, decreasing cell growth, suppressing ALK phosphorylation and inducing apoptosis.[2] Neurite outgrowth induced by expression of the mALK R1279Q mutant could be completely inhibited by TAE684 at 30 nM.

After 4 weeks of treatment with TAE684 at 3 and 10 mg/kg, there is a significant delay in lymphoma development and 100- to 1,000-fold reduction in luminescence signal, without any signs of compound- or disease-related toxicity in Karpas-299 lymphoma model. TAE684 treatment also induces disease regression in established Karpas-299 lymphomas and down-regulates CD30 expression. [1] TAE684 also shows impressive antitumor activity against H3122 CR xenograft tumors. [2] Furthermore, treatment with TAE684 improves the rough eye phenotype of both ALK mutants, especially that seen with ALKR1275Q, whereas Crizotinib has little effect on either phenotype. [3]
