Ripretinib (DCC-2618)

Erlotinib (OSI-774)^New

Erlotinib (OSI-774, CP358774, NSC 718781, Tarceva) is an EGFR inhibitor with IC50 of 2 nM, >1000-fold more sensitive for EGFR than human c-Src or v-Abl. Erlotinib induces autophagy.

Bemcentinib (R428)^New

Bemcentinib (R428, BGB324) is an inhibitor of Axl with IC50 of 14 nM, >100-fold selective for Axl versus Abl. Selectivty for Axl is also greater than Mer and Tyro3 (50-to-100- fold more selective) and InsR, EGFR, HER2, and PDGFRβ (100- fold more selective).

Pexidartinib (PLX3397)^New

Pexidartinib (PLX3397) is an oral, potent mutil-targeted receptor tyrosine kinase inhibitor of CSF-1R, Kit (c-Kit), and FLT3 with IC50 of 20 nM, 10 nM and 160 nM, respectively. Pexidartinib (PLX3397) induces apoptosis and necrosis with antitumor activity. Phase 3.

Masitinib (AB1010)

Masitinib is a novel inhibitor for Kit (c-Kit) and PDGFRα/β with IC50 of 200 nM and 540 nM/800 nM, weak inhibition to ABL and c-Fms. Phase 3.

OSI-930

OSI-930 is a potent inhibitor of Kit (c-Kit), KDR and CSF-1R with IC50 of 80 nM, 9 nM and 15 nM, respectively; also potent to Flt-1, c-Raf and Lck and low activity against PDGFRα/β, Flt-3 and Abl. Phase 1.

Amuvatinib (MP-470)

Amuvatinib (MP-470, HPK 56) is a potent and multi-targeted inhibitor of c-Kit, PDGFRα and Flt3 with IC50 of 10 nM, 40 nM and 81 nM, respectively. Amuvatinib suppresses c-MET and c-RET. Amuvatinib is also active as a DNA repair protein Rad51 inhibitor with antineoplastic activity. Phase 2.

Gefitinib (ZD1839)

Gefitinib (ZD-1839, Iressa) is an EGFR inhibitor for Tyr1173, Tyr992, Tyr1173 and Tyr992 in the NR6wtEGFR and NR6W cells with IC50 of 37 nM, 37nM, 26 nM and 57 nM, respectively. Gefitinib promotes autophagy and apoptosis of lung cancer cells via blockade of the PI3K/AKT/mTOR pathway.

Erlotinib HCl (OSI-744)

Erlotinib HCl (OSI-744, CP358774, NSC 718781) is an EGFR inhibitor with IC50 of 2 nM in cell-free assays, >1000-fold more sensitive for EGFR than human c-Src or v-Abl.

Crizotinib (PF-02341066)

Crizotinib (PF-02341066) is a potent inhibitor of c-Met and ALK with IC50 of 11 nM and 24 nM in cell-based assays, respectively. It is also a potent ROS1 inhibitor with Ki value less than 0.025 nM. Crizotinib induces autophagy through inhibition of the STAT3 pathway in multiple lung cancer cell lines.

Afatinib (BIBW2992)

Afatinib (BIBW2992) inhibits EGFR/ErbB irreversibly in vitro with IC50 of 0.5, 0.4, 10, 14, 1 nM for EGFR^wt, EGFR ^L858R , EGFR ^L858R/T790M ErbB2 (HER2) and ErbB4 (HER4), respectively. Afatinib induces autophagy.
