| 描述 | ALK (anaplastic lymphoma kinase) is a tyrosine kinase that is constitutively activated in certain cancers, following gene alterations such as chromosomal translocation, amplification or point mutation. Alectinib is a potent and selective ALK inhibitor with IC50 value of 1.9nM (measured by enzyme activity). Alectinib was preferentially efficacious against NCI-H2228 cells expressing EML4-ALK, but not ALK fusion-negative NSCLC cell lines, including HCC827 cells (EGFR exon 19 deletion), A549 cells (KRAS mutant), or NCIH522 cells (EGFR wild-type, KRAS wild-type, and ALK wildtype) in monolayer culture. Consistent with that, Alectinib can prevent autophosphorylation of ALK and thus resulted in substantial suppression of phosphorylation of STAT3 and AKT, but not of ERK1/2, in NCI-H2228 NSCLC cells expressing EML4-ALK, but not in ALK fusion-negative A549 cells. The potent inhibition of ALK kinase activity by Alectinib can also be observed in vivo. Oral administration of Alectinib caused dose-dependent decrease of pSTAT3-Tyr705 and pAKT-Ser473 in tumors from mice bearing NCI-H2228 cells at dose < 20mg/kg, with a significant decrease in the expression of STAT3 target genes, such as BCL3, NNMT, SOCS3 and BCL2L1, at dose of 6mg/kg. Administered CH5424802 orally once daily for 11 days at dose 2, 6 and 20mg/kg inhibited tumor growth dose-dependently, with decreased pALK-Tyr1604, in mice bearing NCI-H2228 but not A549. The maximum efficacy can be observed at dose of 60mg/kg for 3 weeks and a prolonged effect with no regrowth of tumor for 4 weeks in this model. Therapeutic efficacy of Alectinib on tumor regression can also be observed in models generated by implantation of KARPAS-299 ALCL cells and NB-1 neuroblastoma cells[1]. | ||
| 作用机制 | Alectinib acts in an ATP-competitive manner and blocks the L1196M gatekeeper mutation of ALK.[1] | ||
