Biological Activity

Description Rociletinib (CO-1686, AVL-301) is an irreversible, mutant-selective EGFR inhibitor with Ki of 21.5 nM and 303.3 nM for EGFRL858R/T790M and EGFRWT in cell-free assays, respectively. Phase 2.
EGFR (L858R/T790M) [1]
(Cell-free assay)
EGFR (wt) [1]
(Cell-free assay)
21.5 nM(Ki) 303.3 nM(Ki)
In vitro

CO-1686 inhibits p-EGFR with IC50 ranging from 62 to 187 nM in the mutant EGFR–expressing cells, while inhibits EGFR phosphorylation with IC50 of > 2,000 nM in the three WT EGFR–expressing cells. CO-1686 selectively inhibits growth of NSCLC cells expressing mutant EGFR with GI50 ranging from 7 to 32 nM, and induces apoptosis. CO-1686–resistant NSCLC cell lines exhibits signs of epithelial-mesenchymal transition and increased sensitivity to AKT inhibitors. [1]

In vivo CO-1686 causes dose-dependent and significant tumor growth inhibition in all EGFR-mutant models as well as human EGFRL858R- and EGFRL858R/T790M-expressing transgenic mice. [1]

Inhibition Kinetics Studies:

Recombinant human wild-type and T790M/L858R double mutant EGFR, both Nterminal GST-tagged, are used in the assay. The Omnia continuous read assay is performed as described by the vendor.
Cell Research:[1]
- Collapse
  • Cell lines: NSCLC cell lines expressing mutant EGFR (HCC827, PC9, HCC827-EPR, and NCI-H1975) and cell lines expressing WT EGFR (A431, NCI-H1299, and NCI-H358)
  • Concentrations: ~10 μM
  • Incubation Time: 72 hours
  • Method: Cells are seeded at 3,000 cells per well in growth media supplemented with 5% FBS, 2 mmol/L, L-glutamine, and 1% penicillin–streptomycin, allowed to adhere overnight, and treated with a dilution series of test compounds for 72 hours. Cell viability is determined by CellTiter-Glo, and results are represented as background-subtracted relative light units normalized to a dimethyl sulfoxide (DMSO)–treated control. Growth inhibition (GI 50) values are determined by GraphPad Prism 5.04. MK-2206 and XL-880 compounds are obtained from Selleck Chemical. CI data are generated using CalcuSyn.

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.
