A quantitative structure-activity relationship (QSAR) study has been made on two different series of anticancer
tyrosine kinase inhibitors, namely a series of 4-alkynyl and 4-alkenyl-quinazolines and a series of N-4,6-pyrimidine-Nalkyl-
N'-phenyl ureas. For the first series, QSAR results indicate that the activity is controlled by the hydrophobicity of
the molecules and molecular connectivity index of the substituent, whereas for the second series of compounds the activity
is found to be controlled by the molecular connectivity index of the substituent and some indicator variables.
