Design, synthesis and biological evaluation of a series of novel 2-benzamide-4-(6-oxy-N-methyl-1-naphthamide)-pyridine derivatives as potent fibroblast growth factor receptor (FGFR) inhibitors

Starting from the phase II clinical FGFR inhibitor lucitanib (2), we conducted a medicinal chemistry approach by opening the central quinoline skeleton coupled with a scaffold hopping process thus leading to a series of novel 2-benzamide-4-(6-oxy-N-methyl-1-naphthamide)-pyridine derivatives. Compound 25a was identified to show selective and equally high potency against FGFR1/2 and VEGFR2 with IC50 values less than 5.0 nM. Significant antiproliferative effects on both FGFR1/2 and VEGFR2 aberrant cancer cells were observed. In the SNU-16 xenograft model, compound 25a showed tumor growth inhibition rates of 25.0% and 81.0% at doses of 10 mg/kg and 50 mg/kg, respectively, with 5% and 10%body weight loss. In view of the synergistic potential of FGFs and VEGFs in tumor angiogenesis observed in preclinical studies, the FGFR/VEGFR2 dual inhibitor 25a may achieve better clinical benefits.

Discovery of Substituted 1H-Pyrazolo[3,4-b]pyridine Derivatives as Potent and Selective FGFR Kinase Inhibitors

Fibroblast growth factor receptors (FGFRs) are important targets for cancer therapy. Herein, we describe the design, synthesis, and biological evaluation of a novel series of 1H-pyrazolo[3,4-b]pyridine derivatives as potent and selective FGFR kinase inhibitors. On the basis of its excellent in vitro potency and favorable pharmacokinetic properties, compound 7n was selected for in vivo evaluation and showed significant antitumor activity in a FGFR1-driven H1581 xenograft model. These results indicated that 7n would be a promising candidate for further drug development.

Design and synthesis of thiadiazoles and thiazoles targeting the Bcr-Abl T315I mutant: From docking false positives to ATP-noncompetitive inhibitors

(Figure Presented) Overcoming resistance: In an effort to optimize our previously identified dual Src/Abl hits, a new series of 1,3,4-thiadiazoles and 1,3-thiazoles were designed and synthesized, paying particular attention to the reduction of their lipophilicity and to the improvement of the affinity towards the drug-resistant T315I mutant. Compound 5 was identified as a promising allosteric inhibitor of the T315I mutant.
