BR-cpd7 is an orally active, selective PROTAC degrader targeting FGFR1 and FGFR2, with a DC₅₀ of 2.2 nM against FGFR1. BR-cpd7 reduces FGFR signaling. BR-cpd7 induces cell cycle arrest and selectively blocks the proliferation of FGFR1/FGFR2-dependent tumor cells. BR-cpd7 exhibits significant antitumor efficacy in FGFR1-dependent lung cancer animal models, while achieving complete depletion of FGFR1. BR-cpd7 can be used for cancer-related research.

DGY-09-192 is a PROTAC FGFR1/2 degrader (FGFR1: DC₅₀ = 4.35 nM; FGFR2: DC₅₀ = 70 nM). DGY-09-192 preferentially degrades wild-type FGFR1/2 and multiple FGFR2 fusion proteins (including FGFR2-PHGDH and FGFR2-OPTN). DGY-09-192 suppresses downstream FGFR signaling (reducing phosphorylation of FRS2 Y196 and ERK1/2 T202/Y204) in vitro and vivo. DGY-09-192 can be used for the study of FGFR-driven cancers.

LC-MF-4 is a selective FGFR3 PROTAC degrader with a DC₅₀ of 30.89 nM in KMS-11 cells. LC-MF-4 inhibits the metabolic function of FGFR3-TACC3 fusion positive cancers with reduction of ATP synthesis and inhibition of mitochondrial biogenesis genes. LC-MF-4 has potent antitumor activity in the Ba/F3-FGFR3-TACC3 xenograft mice model. LC-MF-4 can be used for FGFR3-altered cancers like bladder cancer and urothelial carcinoma (UC) research.

PROTAC FGFR2 degrader 1 (compound N5) is a PROTAC that effectively targets FGFR2 with DC₅₀ of 6.46 nM, the FGFR2 IC₅₀ is 0.08 nM. PROTAC FGFR2 degrader 1 has anti-proliferative activity and highly selective, induces G0/G1 arrest of KATOIII and SNU16 cell cycle and inhibits apoptosis by reducing the activation of p-ERK and p-PLCγ, the downstream proteins of FGFR2. PROTAC FGFR2 degrader 1 potently inhibits the growth of SNU16 xenograft tumors in mouse model.

PROTAC FGFR3 Degrader-1 is a fibroblast growth factor receptor 3 (FGFR3) PROTAC degrader, promotes FGFR3 degradation via the ubiquitin-proteasome pathway, and inhibits the downstream FGFR3/PI3K/AKT signaling pathway. PROTAC FGFR3 Degrader-1 can be used for the research of hepatocellular carcinoma.

PROTAC FGFR1 degrader-1 (compound S2H) is a PROTAC degrader targeting FGFR1, with IC₅₀=26.81 nM and DC₅₀=39.78 nM in KG1a cells. PROTAC FGFR1 degrader-1 is composed of CRBN-type E3 ligase ligand (blue part) Pomalidomide (HY-10984), target protein ligand (red part) FGFR1 ligand-1 (HY-170871), and PROTAC linker (black part) 9-Bromononanoic acid (HY-W007587), in which the E3 ligase ligand and linker form a conjugate E3 Ligase Ligand-linker Conjugate 164 (HY-170870).

LC-MG-10 is a selective molecular glue degrader targeting FGFR2, with a DC₅₀ of 230.2 nM in KATO III cells. LC-MG-10 induces proteasomal degradation of FGFR2 via a covalent molecular glue mechanism. LC-MG-10 inhibits cancer cell proliferation. LC-MG-10 suppresses FGFR2-mediated PI3K/AKT and MAPK/ERK signaling pathways. LC-MG-10 can be used in studies related to gastric cancer.

LC-MG-5 is a selective molecular glue degrader targeting FGFR2, with a DC₅₀ of 231.7 nM in KATO III cells. LC-MG-5 induces proteasomal degradation of FGFR2 in a DCAF16-dependent manner via a covalent molecular glue mechanism. LC-MG-5 inhibits cancer cell proliferation. LC-MG-5 suppresses PI3K/AKT and MAPK/ERK signaling pathways mediated by FGFR2. LC-MG-5 can be used in the research of gastric cancer.

FGFR2 degrader 1 (compound 28E) is a selectively PROTACS degrader of FGFR2, with the DC₅₀ of 0.645 nM. FGFR2 plays an important role in cancer research (Pink: ligand of target protein; (HY-13304) black: linker; blue: ligand of E3 ligase).

CYB-5067 is a FGFR molecular glue degrader with a DC₅₀ of 27 nM against FGFR2. CYB-5067 inhibits FGFR1, FGFR3, FGFR4 and downstream FGFR signaling pathways, induces antiproliferative activity in vitro, and exhibits sustained target protein inhibition in vivo without obvious hook effect. CYB-5067 shows significant tumor growth inhibitory activity in the ETV6-FGFR2 fusion Ba/F3 xenograft model. CYB-5067 can be used for the research of FGFR-driven cancers.
