Abstract

Inhibition of tight junction formation between two malaria parasite proteins, apical membrane antigen 1 and rhoptry neck protein 2, crucial for red blood cell invasion, prevents the disease progression. In this work, we have utilized a unique approach to design a chimeric peptide, prepared by fusion of the best features of two peptide inhibitors, that has displayed parasite growth inhibition, in-vitro, with nanomolar IC50, which is hundredfold better than any of its parent peptides. Further, to gain structural insights, we computationally modeled the hybrid peptide on its receptor.
