Description Malaria parasite Plasmodium falciarum are becoming drug resistant and the present drugs are becoming ineffective towards the disease. The Plasmodium falciparum causes the most malignant form of malaria highly prevalent to North–East India. In this investigation, a study was conducted to search and predict potent anti-malarial lead compounds from two traditionally important anti-malarial plant, Carcia papaya and Swertia chirata. Dihydropteroate synthase (DHPS) is an essential enzyme required for the folate biosynthesis in Plasmodium falciparum. Till date, three dimensional (3D) structure of DHPS is not yet elucidated and hence, homology model of DHPS was generated and docked with these plant derived compound. The study identified few phytochemical such as Atovquone, Nitroblue tetrazolium, Caffeic Acid and Kaempferol in terms of least docking and optimum ADME scores as a novel DHPS inhibitor.
