The disclosure provides novel FGFR inhibitors based on the pyridinylpyrimidine. The disclosure includes inhibitors with broad inhibitory activity against all FGFR isoforms, and inhibitors with selective inhibition against FGFR4. These novel pyridinylpyrimidine-based FGFR inhibitors, or their derivatives, have strong potential to be used to treat cancer.

Design, synthesis and SAR of novel ethylenediamine and phenylenediamine derivatives as factor Xa inhibitors
We previously reported on a series of cyclohexanediamine derivatives as highly potent factor Xa inhibitors. Herein, we describe the modification of the spacer moiety to discover an alternative scaffold. Ethylenediamine derivatives possessing a substituent at the C1 position in S configuration and phenylenediamine derivatives possessing a substituent at the C5 position demonstrated moderate to strong anti-fXa activity. Further SAR studies led to the identification of compound 30h which showed both good in vitro activity (fXa IC50 = 2.2 nM, PTCT2 = 3.9 μM) and in vivo antithrombotic efficacy.
