- Design, synthesis and biological evaluation of novel pyrimidine, 3-cyanopyridine and m-amino-N-phenylbenzamide based monocyclic EGFR tyrosine kinase inhibitors
-
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 μM for EGFR and 5 μM for A-549 and HL60 cells growth inhibition.

- Synthesis and evaluation of novel pyrimidine-based dual EGFR/Her-2 inhibitors
-
A structure-activity relationship study of 4-anilinopyrimidines for dual EGFR/Her-2 inhibitor has resulted in the identification of 4-anilino-5-alkenyl or 5-alkynyl-6-methylpyrimidine derivatives that have exhibited effective inhibitory activity against both enzymes. The presence of 5-alkenyl or 5-alkynyl moiety bearing terminal hydrophilic group played important role for inhibition of these enzymes. Selected compounds in the series demonstrated some activity against Her-2 dependent cell line (BT474).
