                                    36 new compounds with the typical skeleton of 4-anilino-5-vinyl/ethynyl pyrimidine, 4-anilino-3-cyano-5-vinyl/ethynyl/phenyl pyridine, and m-amino-N-phenylbenzamide, are designed, synthesized and selectively tested on EGFR, ErbB-2 kinases, and A-549, HL60 cells growth inhibition. Results from the bioactivity and chemical structures yield preliminary structure-activity relationships (SARs). The most potent 5-ethynylpyrimidine derivative 20a has an IC50 value of 45 nM to EGFR kinase. Several compounds of other series also show IC50 values <1 mu M for EGFR and <5 mu M for A-549 and HL60 cells growth inhibition. (C) 2013 Published by Elsevier Ltd.
