Malaria parasites have become the major health threat in increasing resistance toward common antimalarial drugs and become prime factors causing the strength of the disease. The objective of this study was investigating novel cinchona alkaloid derivatives (CADs) as potential antimalarial agents through molecular docking, pharmacopore modeling and biosynthesis design. Protein structure and cinchona alkaloid derivative structures were taken and performed for molecular interaction studies, pharmacophore modeling and mapping the binding modes of receptor-inhibitors which may increase the possibility of success rate in finding potential antimalarial candidates. Here, we report the greatest prospective inhibitor of Pf falcipain-2 is cinchonidine salicylate (-9.1 kcal/mol) through molecular docking approach. This compound exhibited distortion free of Lipinski`s rule. Hence, cinchonidine salicylate showed the most potential compound as antimalarial inhibitor over other cinchona alkaloid derivatives. Eventually, we construct biosynthesis pathways by using iron oxide nanoparticle (IONP) that could act as a coated nanoparticle to the natural bioactives to acquire optimum yield of the product by making coated nanoparticle with CADs which are powerful biosynthesis application in green environment of aqueous solution.
