Results from molecular docking calculations and Grid mapping laid the foundations for a structure-based optimization approach to improve the biological properties of pyrazolo-pyrimidine derivatives in terms of inhibition of Abl enzymatic activity and anti proliferative properties toward human leukemia cells. Insertion of halogen substituents with various substitution patterns, suggested by simulations, led to a significant improvement of leukemia cell growth inhibition and to an increase up to 1 order of magnitude of the affinity toward Abl.
