“…Both inhibitors exhibited excellent potency against typical cancer cell lines harboring FGFR amplifications or mutations, including the FGFR4-dependent cell line A2780, which is resistant to many current FGFR inhibitors. FGFR4 has been reported to play a very important role in metastasis, drug resistance, and poor prognosis (23,(68)(69)(70); therefore FIIN-2 and FIIN-3, with good FGFR4 potency, show promising potential for application in many FGFR-dependent cancer types such as breast cancer (63,71) and hepatocellular carcinoma (72,73). In addition, they are capable of overcoming the valine-to-methionine gatekeeper mutation in H2077 and H1581 cell lines, although similar mutations found in patients' specimens have been demonstrated experimentally to confer resistance to the leading clinical FGFR inhibitors (19,48,50).…”

The human FGF receptors (FGFRs) play critical roles in various human cancers, and several FGFR inhibitors are currently under clinical investigation. Resistance usually results from selection for mutant kinases that are impervious to the action of the drug or from up-regulation of compensatory signaling pathways. Preclinical studies have demonstrated that resistance to FGFR inhibitors can be acquired through mutations in the FGFR gatekeeper residue, as clinically observed for FGFR4 in embryonal rhabdomyosarcoma and neuroendocrine breast carcinomas. Here we report on the use of a structure-based drug design to develop two selective, next-generation covalent FGFR inhibitors, the FGFR irreversible inhibitors 2 (FIIN-2) and 3 (FIIN-3). To our knowledge, FIIN-2 and FIIN-3 are the first inhibitors that can potently inhibit the proliferation of cells dependent upon the gatekeeper mutants of FGFR1 or FGFR2, which confer resistance to first-generation clinical FGFR inhibitors such as NVP-BGJ398 and AZD4547. Because of the conformational flexibility of the reactive acrylamide substituent, FIIN-3 has the unprecedented ability to inhibit both the EGF receptor (EGFR) and FGFR covalently by targeting two distinct cysteine residues. We report the cocrystal structure of FGFR4 with FIIN-2, which unexpectedly exhibits a "DFG-out" covalent binding mode. The structural basis for dual FGFR and EGFR targeting by FIIN3 also is illustrated by crystal structures of FIIN-3 bound with FGFR4 V550L and EGFR L858R. These results have important implications for the design of covalent FGFR inhibitors that can overcome clinical resistance and provide the first example, to our knowledge, of a kinase inhibitor that covalently targets cysteines located in different positions within the ATP-binding pocket.drug discovery | cancer drug resistance | kinase inhibitor | structure-based drug design R eceptor tyrosine kinases (RTKs) serve as critical sensors of extracellular cues that activate a myriad of intracellular signaling pathways to regulate cell state. There are 58 receptor tyrosine kinases in the human genome, and many have been demonstrated to be constitutively activated through amplification or mutation in particular cancers. The signals emanating from these RTKs, such as epidermal growth factor receptor (EGFR), FGF receptor (FGFR), platelet-derived growth factor receptor (PDGFR), protein kinase Kit (KIT), and protein kinase c-Met (MET), have been pharmacologically proven to be essential to the survival of cancers expressing mutant forms of these proteins. However, rapid resistance to monotherapy with first-generation RTK inhibitors has been universally observed. Resistance typically arises from the emergence of cancer cells expressing mutant forms of RTKs that are impervious to the action of first-generation drugs or from the activation of by-pass signaling mechanisms. Resistance can be overcome by developing new inhibitors that target the mutant RTK directly or target bypass signaling mechanisms. Indeed this approach has been deployed succes...

Introduction: Preclinical data suggest that the single nucleotide polymorphism substituting a glycine for an arginine in codon 388 of the FGFR4 transmembrane domain may increase the proliferation of xenografted neuroendocrine cell lines and decrease their sensitivity to everolimus by modulating STAT3 signaling and the mTOR pathway. Aim: To evaluate the prognostic and predictive values of this polymorphism on everolimus efficacy in patients treated for digestive neuroendocrine tumor (NET). Patients and Methods: This monocentric retrospective cohort included patients with small bowel NET (SBNET) and pancreatic NET (PNET) treated with everolimus (2006-2013). The patients were genotyped by classical sequencing, and mTOR pathway activity was assessed by immunochemistry on formalin-fixed paraffin-embedded samples (PTEN/pPTEN/pAKT/pmTOR/pS6/p4EBP1). Results: Forty-one patients (21 males, median age 57 years) with PNET (n = 28), SBNET (n = 12) or NET of unknown origin (n = 1), grade 1 (n = 8), 2 (n = 27), 3 (n = 3) or unknown grade (n = 3), were studied. At least one 388Arg allele was found in 14/23 PNET and 10/11 SBNET. Progression-free survival in the whole population and the PNET subgroup was not influenced by the presence of one or two 388Arg alleles [HR = 1.31 (0.58-2.99), p = 0.52 and HR = 1.11 (0.45-2.73), p = 0.82, respectively]. Similarly, overall survival was not influenced. Finally, mTOR pathway molecule expression was not modified by the presence of at least one 388Arg allele. Conclusion: The Gly388Arg FGFR4 polymorphism does not seem to have a prognostic value in digestive NET. In addition, it neither predicts the response to everolimus nor modifies the activation of the mTOR pathway.

Fibroblast growth factor 19 (FGF19) promotes tumor growth in various types of cancer, but its function has not been investigated in the context of colorectal adenoma. Here, we report that FGF19 expression was greater in colorectal adenoma than in normal tissues, as measured by an enzyme-linked immunosorbent assay, quantitative reverse-transcription PCR and immunohistochemistry. FGF19 expression was also elevated in a subset of human colon cancer cell lines. Moreover, FGF receptor 4 (FGFR4), the cognate receptor for FGF19, was upregulated in colorectal adenoma tissues. Lipid levels and body mass index values strongly correlated with FGF19 and FGFR4 levels in patients with colon adenomas. These observations indicate that the FGF19/FGFR4 pathway may be involved in the development of neoplasia, and that FGF19 may be a valuable diagnostic marker for the identification of patients with colorectal adenomas.
