生物活性

Alectinib Hydrochloride (CH5424802 Hydrochloride; RO5424802 Hydrochloride; AF-802 Hydrochloride) is a potent, selective, and orally available ALK inhibitor with an IC50 of 1.9 nM and a Kd value of 2.4 nM (in an ATP-competitive manner), and also inhibits ALK F1174L and ALK R1275Q with IC50s of 1 nM and 3.5 nM, respectively[1]. Alectinib demonstrates effective central nervous system (CNS) penetration[2].

IC50 & Target

IC50: 1.9 nM (ALK), 1 nM (ALKF1174L), 3.5 nM (ALKR1275Q)[1]
Kd: 2.4 nM (ALK)[1]

体外研究
(In Vitro)

Alectinib (0-1000 nM; 2 hours; NCI-H2228 cells) treatment could prevent autophosphorylation of ALK in NCI-H2228 cells expressing EML4-ALK, and it also resulted in substantial suppression of phosphorylation of STAT3 and AKT[1].
Alectinib (0-1000 nM; 5 days; HCC827, A549, or NCIH522 cells) treatment reduces cell activity in a dose-dependent manner[1].

Western Blot Analysis[1]

Cell Line: NCI-H2228 cells
Concentration: 0 nM,10 nM,100 nM, 1000 nM
Incubation Time: 2 hours
Result: Inhibition of ALK phosphorylation and signal transduction.

Cell Viability Assay[1]

Cell Line: HCC827, A549, or NCIH522 cells
Concentration: 0-1000 nM
Incubation Time: 5 days
Result: Reduced cell activity in a dose-dependent manner.

体内研究
(In Vivo)

Alectinib (0.2-20 mg/kg; oral administration; once daily; for 11 days; SCID or nude mice bearing NCI-H2228 cells) treatment can result in dose-dependent tumor growth inhibition (EC50 of 0.46 mg/kg) and tumor regression. At any dose level, no differences in body weight or gross signs of toxicity are observed[1].
