Batoprotafib (TNO155) is a potent selective and orally active allosteric inhibitor of wild-type SHP2 (IC50=0.011 µM). Batoprotafib has the potential for the study of RTK-dependent malignancies, especially advanced solid tumors[1].
Batoprotafib shows an IC50 of 0.008 μM in KYSE520 pERK assay and shows an IC50 of 0.100 μM in KYSE520 5-day cell proliferation assay. The off-target IC50 values are 18 μM, 6.9 μM, and 11 μM for Cav1.2, VMAT, and SST3, respectively[1].
Batoprotafib (0-1000 nM; 6 days) inhibits the viability of NCI-H3255, HCC827, and PC9 cells with IC50 values lower than 1.5 μM. Batoprotafib is efficacious in EGFR-mutant NSCLC cell lines[2].
Batoprotafib is efficacious in acquired resistance models of EGFR inhibitors and demonstrates combination benefit with EGFR inhibitors[2].
Batoprotafib enhances the efficacy of KRASG12C inhibitors against KRASG12C lung and colorectal cancers[2].
Batoprotafib inhibits immune-suppressive macrophages and synergizes with PD1 blockade[2].
The oral bioavailability in mouse, rat and money are 78%, 86%, and 60%, respectively[1].
Batoprotafib (20 mg/kg; p.o.; twice daily for 40 days) inhibits tumor growth and is more effective when combined with Dabrafenib (HY-14660) plus Trametinib (HY-10999) in nude mice bearing HT-29 xenografts[2].
Batoprotafib (7.5 mg/kg; p.o.; b.i.d. or q.d. for 36 days) plus JDQ-443 (HY-139612) (100 mg/kg; p.o.; q.d.) improves the single-agent activity of JDQ443 in KRASG12C-mutated cell-derived (CDX) models in nude mice[3].
