  • Varlitinib purchased from Selleck.

     

    Reversal effect of ARRY-334543 on the sensitivity of HEK/MRP7 cells to vincristine. The figure showes the survival curves of cells at different concentrations of vincristine with or without ARRY-334543. Cell viability was determined by MTT Assay. HEK293 is human embryonic kidney cell line while HEK/MRP7 is MRP7-transfected cell line. Cepharanthine was used as a positive control of MRP7 inhibitor.

    Reversal effect of ARRY-334543 on the sensitivity of HEK293-ABCG2-R2 cells to mitoxantrone. The figure showes the survival curves of cells at different concentrations of mitoxantrone with or without ARRY-334543. Cell viability was determined by MTT Assay. HEK293 is human embryonic kidney cell line while HEK293-ABCG2-R2 is ABCG2-transfected cell line. Nilotinib was used as a positive control of ABCG2 inhibitor.

ARRY334543 behaves as a reversible ATP-competitive inhibitor with nanomolar potency (Ki=1 nM) both in vitro and in cell-based proliferation assays using A431 and BT-474 cells. ARRY334543 is an AKT pathway inhibitor in cells that contains active ErbB-2 receptors. ARRY334543 suppresses ErbB-2 and ErbB-1 phosphorylation in human cancer cells, such as BT-474 with IC50 of 43 nM) and A431 with IC50 of 36 nM) that overexpress ErbB-2 and ErbB-1, respectively.[1]

In vivo When dosed orally, ARRY334543 prevents growth of human tumor xenografts that overexpress ErbB-1 (A431) or ErbB-2 (MDA-MB-453) in a dose-dependent manner. In mouse xenograft models utilizing the EGFR overexpressing tumor line A431, ARRY334543 demonstrates significant dose related tumor growth prevention when administered orally, BID, for 21 days. ARRY334543 has very good in vivo and in vitro PK/ADME properties and has shown excellent activity in numerous mouse tumor xenograft models including epidermoid (A431), breast (BT-474, MDA-MB-453), non-small cell lung (H1650, A549, 292), colorectal (Lovo, HT-29) and gastric (N87) carcinoma models. In the BT-474 model, ARRY334543 demonstrates significant dose-related tumor growth inhibition (69% at 100 mg/kg/d and 98% at 200 mg/kg/d) with significant regressions at both dose levels. Excellent single agent activity for ARRY334543 in the SK-OV-3 ovarian carcinoma xenograft model as well as additive acitivity to trastuzumab in SK-OV-3, BT-474 and NCI-N87 models has been demonstrated. In the BT-474 model, ARRY334543 displays excellent additive activity and tolerability with docetaxel. [2]

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.
