AP26113 is highly active against both sensitive and resistant H3122 cells, decreasing cell growth, suppressing ALK phosphorylation and inducing apoptosis in a dose dependent manner. AP26113 decreases p-ALK in the H3122 and H3122 CR cells, with IC50 values of 7.4 versus 16.8 nM, respectively. AP26113 decreases cell number in Ba/F3 cells expressing either native or mutant EML4-ALK with IC50 of 10 nM and 24 nM, respectively.  AP26113 inhibits cell growth of SU-DHL-1, H3122 and Ba/F3-EML4-ALK v1 cell lines with GI50 of 9 nM, 4 nM and 13 nM, respectively. AP26113 inhibits phosphorylation of ALK with IC50 of 3.2 nM, 1.5 nM and 2.1 nM in Karpas-299, SU-DHL-1 and L-82 cell lines. AP26113 dose-dependently inhibits phosphorylation of ALK and ERK in Karpas-299 and H3122 cells.  AP26113 inhibits cell growth with IC50 of 11 nM and 16 nM in Ba/F3 line (native EML4-ALK) and Ba/F3 line (EML4-ALK G1269S mutants). AP26113 inhibits ALK phosphorylationh with IC50 of 74 nM and 335 nM in Ba/F3 line (native EML4-ALK) and Ba/F3 line (EML4-ALK E1210K mutants). AP26113 (10 mg/kg-75 mg/kg) is efficacious in PF-02341066-resistant EML4-ALK mutant mouse xenograft models. AP26113 induces regression of tumors expressing native EML4-ALK and the G1269S and L1196M mutants at 25 mg/kg, 50 mg/kg and 50 mg/kg, respectively.  AP26113 inhibits EGFR phosphorylation and viability with IC50 of 75 nM and 114 nM, respectively, in Ba/F3 cells expressing EGFR-DEL. AP26113 inhibits EGFR phosphorylation and viability with IC50s of 15 and 281 nM, respectively, in Ba/F3 cells expressing EGFR-DEL/T790M. AP26113 inhibits EGFR phosphorylation with an IC50 of 62 nM and cell growth with a GI50 of 165 nM in a NSCLC line expressing EGFR-DEL (HCC827). AP26113 inhibits EGFR phosphorylation with an IC50 of 59 nM and cell growth with a GI50 of 245 nM in HCC827 cells expressing EGFR-DEL/T790M. AP26113 potently inhibits SLC34A2-ROS-driven signaling and proliferation in a dose dependent manner in HCC78 NSCLC cells. 
|In vivo||AP26113 (< 50 mg/kg) dose-dependently inhibits p-ALK in tumor of Karpas-299 xenograft mice model. AP26113 (< 50 mg/kg) dose-dependently inhibits tumor growth in Karpas-299 xenograft mice model and H3122 xenograft mice model. AP26113 demonstrates favorable properties including moderate in vitro plasma protein binding (47%, 70% and 76% in human, rat, mouse), negligible inhibition of major CYP isoforms. AP26113 (10 mg/kg) is well-tolerated with Cmax of 2587 ng/mL and AUC of 41120 hr.ng/mL in rats.  AP26113 (25 mg/kg) leads to tumor regression in HCC827(EGFR-DEL) or HCC827(EGFR-DEL/T790M) xenograft mice model. |

* 1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*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).
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 )
* 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.
