The synthesis and SAR of a series of 6-chloro-4-fluoroalkylamino-2-heteroaryl-5-(substituted)phenylpyrimidines as anti-cancer agents are described. This series of 2-heteroarylpyrimidines was developed by modifying a series of anti-tumor [1,2,4]triazolo[1,5-a]pyrimidines and 2-cyanoaminopyrimidines we reported earlier. For the 2-heteroaryl group, the best activity is obtained when the heteroaryl group has a nitrogen atom at the ortho-position to the pyrimidyl core. The structure-activity relationship for the rest of the molecule in this 2-heteroarylpyrimidine series mimics that of the [1,2,4]triazolo[1,5-a]pyrimidine series. Like triazolopyrimidines and 2-cyanoaminopyrimidines, the 2-heteroarylpyrimidines retain the capability to overcome multidrug resistance due to Pgp. Mechanism of action studies showed that the lead compounds behaved in the same manner as triazolopyrimidines and 2-cyanoaminopyrimidines. The lead compounds in this series are more potent than the corresponding triazolopyrimidines in vitro and in vivo. Compound 21 (PTI-868) showed tumor growth inhibition in several nude mouse xenograft models, and was selected to advance to preclinical development.
