In the search of novel chemotherapeutic agents for emerging drug resistant parasites, the hybridization approaches have successfully emerged as an efficient tool in malarial chemotherapy. Herein, a rational design and synthesis of novel 8-aminoquinoline and pyrazolopyrimidine hybrids and their antimalarial activity against wild type Plasmodium falciparum (Pf_NF54) and resistant strain (Pf_K1) is reported. The medicinal chemistry approach to expand the scope of this series resulted in an identification of potent compounds with nanomolar potency (best IC50 5-10nM). Systematic structure activity relationship (SAR) studies revealed that pyrazolopyrimidine and 8-aminoquinoline ring are essential for achieving good P. falciparum potency. The docking study revealed that the compound 6 can retain some of the critical interactions within pfDHODH drug target.
