Derivatives of the tyrosine kinase inhibitor dasatinib were synthesized by esterification with 25 carboxylic acids, including amino acids and fatty acids, thereby extending the drug to interact with more diverse sites and to improve specificity. The dasatinib–l-arginine derivative (Das-R, 7) was found to be the most potent of the inhibitors tested, with IC50values of 4.4, 10) with an IC50value of 3.2 μm for Csk compared with 35 nm for Src. Furthermore, many compounds displayed increased selectivity toward Src over Abl. Compounds 15 (Das–glutamic acid) and 13 (Das–cysteine) demonstrated the largest gains (10.2 and 10.3 Abl/Src IC50ratios). Das-R (IC50=2.06 μm) was significantly more potent than the parent dasatinib (IC50=26.3 μm) against Panc-1 cells, whereas both compounds showed IC5051.2 pm against BV-173 and K562 cells. Molecular modeling and binding free energy simulations revealed good agreements with the experimental results and rationalized the differences in selectivity among the studied compounds. Integration of experimental and computational approaches in the design and biochemical screening of dasatinib derivatives facilitated rational engineering and diversification of the dasatinib scaffold, providing useful insight into mechanisms of kinase selectivity.
