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]

Protocol (from reference)

Kinase Assay:[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]
  • 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.
Animal Research:[1]
  • Animal Models: Human EGFRL858R- and EGFRL858R/T790M-expressing transgenic mice.
  • Dosages: ~50 mg/kg
  • Administration: Oral gavage

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
