    Abstract:
    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 antiproliferative 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.
