Biological Activity

Description Alectinib is a second generation oral drug that selectively inhibits the activity of anaplastic lymphoma kinase (ALK) tyrosine kinase.
ALK [1]
1.9 nM
In vitro

Alectinib inhibits ALK with an IC50 value of 1.9 nmol/L and shows higher selectivity for ALK than for a number of other serine/tyrosine kinases. It also inhibits the ALK gatekeeper mutation L1196M with an IC50 of 1.56 nmol/L. Alectinib is effective with crizotinib-resistant ALK mutations L1196M, F1174L, R1275Q and C1156Y. In the KARPAS-299 (lymphoma), NB-1 (neuroblastoma) and NCI-H2228 (lung cancer) ALK-positive cell lines, alectinib inhibits cell proliferation with IC50 values of 3, 4.5 and 53 nmol/L, respectively[1].

In vivo Alectinib dose-dependently inhibits EML4-ALK positive NCI-H2228 xenograft model at doses ranging from 2 to 20 mg/kg p.o., q.d. Significant efficacy is also achieved in the EML4-ALK L1196M-driven tumors[1]. It has antitumor activity against cancers with ALK gene alterations[2].

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
