A R T I C L E I N F O A B S T R A C T Article history: Quantitative structure–activity relationships (QSAR) has been a reliable study in the Received 2019-02-16 development of models that predict biological activities of chemical substances based on Accepted 2019-06-27 Available online 2019-06-30 their structures for the development of novel chemical entities. This study was carried out on 44 compounds of 4-amidinoquinoline and 10-amidinobenzonaphthyridine derivatives to p a l a v r a s - c h a v e develop a model that relates their structures to their activities against Plasmodium QSAR falciparum. Density Functional Theory (DFT) with basis set B3LYP/6-31G was used to ∗ Antimalaria optimize the compounds. Genetic Function Algorithm (GFA) was employed in selecting Plasmodium falciparum descriptors and building the model. Four models were generated and the model with best 4-Amidinoquinolina internal and external validation has internal squared correlation coefficient ( 2) of 0.9288,
