Altiratinib

Synonyms: DCC-2701

Altiratinib (DCC-2701) is a potent single-digit nanomolar inhibitor of TRK, Met (c-Met), TIE2, and VEGFR2 kinases with IC50 vaules of 0.9 nM, 4.6 nM, and 0.8 nM for TRKA, B, and C, respectively. It inhibits Met (c-Met) and Met (c-Met) mutant with IC50 values in the range of 0.3-6 nM.

Altiratinib is >10-fold selective for MET versus FMS and KIT, and >50-fold selective for MET versus ABL1, FYN, HER1 (EGFR), p38α (MAPK14), PDGFRα, PDGFRβ, RET, and SRC. Altiratinib exhibits IC50s of 0.69 nmol/L in K562 cells, 1.2 nmol/L in SK-N-SH cells for inhibition of NGF-stimulated TRKA phosphorylation. Altiratinib inhibits constitutive TRKA phosphorylation with an IC50 of 1.4 nmol/L in KM-12 cells. Altiratinib inhibits HGF-stimulated MET phosphorylation in HUVECs, exhibiting an IC50 of 2.3 nmol/L. In ANG1-stimulated HUVECs and EA.hy926 cells, altiratinib exhibits IC50 values of 1.0 nmol/L and 2.6 nmol/L, respectively, for inhibition of TIE2 phosphorylation. In VEGF-stimulated HUVECs, altiratinib inhibits VEGFR2 phosphorylation with an IC50 of 4.7 nmol/L. Altiratinib potently inhibits cellular proliferation in MET-amplified EBC-1 and MKN-45 cells, as well as TPM3-TRKA fusion KM-12 cells, but only weakly inhibits other cancer cell lines, including proliferation of M-NFS-60 (IC50, 770 nmol/L); A375, BT-474, HCT-116, PC-3, SK-MEL-28, U87, and A549 cells (IC50s > 1,000 nmol/L)[1].

Incubation Time 72 h
Method

Cells are added to 96-well (EBC-1, M-NFS-60, and SK-MEL-28: 2,500 cells/well; MKN-45: 5,000 cells/well; MV-4-11: 10,000 cells/well) or 384-well plates (A375 and HCT-116: 625 cells/well; BT-474, KM-12, PC-3, and U-87-MG: 1,250 cells/well). Plates are incubated for 72 hours. Viable cells are quantified using resazurin using a plate reader with excitation at 540 nm and emission at 600 nm.
In Vivo
In vivo

Altiratinib alone and in combination with bevacizumab increases survival and decreases circulating TIE2+-expressing monocytes in the U87 glioma model. In the PyMT syngeneic mammary tumor model which recapitulates many features of human breast cancer, altiratinib alone and in combination with paclitaxel inhibits PyMT mammary tumor growth, reduces tumoral TIE2+ stromal cell density, and inhibits lung metastasis. Altiratinib achieves a brain:plasma ratio of 0.23 after systemic dosing, indicating significant penetration of the murine blood-brain barrier[1].

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.
