PROTACEGFRdegrader 9 (Compound C6) is an orally active, CRBN-based PROTAC EGFR degrader. It has a DC50 of 10.2 nM and a Kd of 240.2 nM against EGFRL858R/T790M/C797S. PROTACEGFRdegrader 9 demonstrates effective degradation activity against various EGFR mutants while not affecting EGFRWT.

ALK/ROS1-IN-5 (compound X4) is a selective inhibitor of ALK and ROS1 kinases, with IC50 values of 0.512 μM for ALK and 0.766 μM for ROS1. It inhibits H2228 cells with an IC50 of 0.034 μM and induces apoptosis in cancer cells in a dose-dependent manner. Additionally, ALK/ROS1-IN-5 effectively suppresses the expression of p-ALK and p-ERK in cancer cells.

Potent, selective oral PROTAC BTK Degrader-1; IC50: 34.51 nM (WT), 64.56 nM (BTK-481S); reduces BTK protein, inhibits tumors.

EGFR-IN-144 (Compound 4B) inhibits EGFR (IC50=0.639 µg/mL) and tubulin polymerization (IC50=7.339 µg/mL). It exhibits cytotoxicity in various cancer cells with a GI50 at the nanomolar level. EGFR-IN-144 reduces the expression of mTOR, TNF-α, and IL-6, causes G1/S phase cell cycle arrest, and induces apoptosis.

EGFR-IN-110 (Compound 6) is a covalent inhibitor of EGFR, demonstrating pIC50 values of 9.2 for the EGFR enzyme and 8.7 for EGFR cells. It exhibits strong efficacy in targeting EGFR and maintains good kinase selectivity.

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.
