KIT/PDGFRA-IN-1 (compound 19) is an inhibitor targeting the stem cell growth factor receptor (KIT) and platelet-derived growth factor receptor alpha (PDGFRA). Its IC50 values are 2.3 µM for KIT-wt, 12 µM for KIT-D816H, 492 µM for KIT-T670I, 0.8 µM for PDGFRA-wt, 99.9 µM for PDGFRA-D842V, 42.3 µM for PDGFRA-T674I, and 4.3 µM for PDGFRA-G680R. The GR50 values for GIST-T1, T1-a-D842V, and GIST-48B cell lines (gastrointestinal stromal tumor cell lines with PDGFR and KIT mutations) are 12 nM, 8900 nM, and ≥10,000 nM, respectively.

EGFR/COX-2-IN-1 is an EGFR/COX-2 inhibitor that effectively targets EGFRWT, EGFRT790M, COX-1, and COX-2 with IC50 values of 0.12, 0.076, 20.1, and 1.52 μM, respectively. It inhibits MCF-7, HT-29, and A-549 cells with IC50 values of 1.20, 5.14, and 14.81 μM, respectively. The compound induces apoptosis by upregulating Bax protein and downregulating Bcl-2 protein levels. Additionally, EGFR/COX-2-IN-1 significantly increases the proportion of cells in the G2/M phase in MCF-7 cells, demonstrating a broad-spectrum antitumor effect.

Zilurgisertib (INCB-000928) is a selective and potent ALK 2 inhibitor for the study of cancer and MF anemia.

BW710 is an orally active inhibitor specifically targeting fibroblast growth factor receptor 2 (FGFR2). It effectively inhibits the proliferation of BaF3-FGFR2 cells with an IC50 value of 2.8 nM. BW710 completely suppresses FGFR2 enzymatic activity and demonstrates selectivity among 75 tyrosine kinases, including FGFR1, FGFR3, and FGFR4, at a 1 μM concentration. Additionally, BW710 impedes FGFR2 signaling and selectively inhibits the proliferation of cancer cells driven by FGFR2. It exhibits promising pharmacokinetic properties, with an oral bioavailability of 29% in mice.

FDU73 is a potent and selective BTK PROTAC degrader with a DC50 of 2.9 nM in JeKo-1 cells. It inhibits tumor cell proliferation and exhibits antitumor activity.
