Targeting epigenetic pathways could open new, promising treatment avenues. In this study, we focus on the essential Bromodomain Protein 1 (PfBDP1) of the malaria pathogen Plasmodium falciparum. Utilizing the pan-selective bromodomain inhibitor MPM6, we identified a potent initial hit and subsequently developed it into a nanomolar binder. Through a combination of virtual docking, isothermal titration calorimetry, and X-ray crystallography, we elucidated the molecular interactions of the new inhibitors with the bromodomain (BRD) of the protein (PfBDP1-BRD). Our findings include the first co-crystallized inhibitors with the structures of PfBRD1-BRD as well as the bromodomain of the close homologous protein of Plasmodium vivax (PvBDP1-BRD). The structures provide new insights into their binding mechanisms. Further validation using conditional knockdown of PfBDP1 in P. falciparum demonstrated parasite sensitivity to the inhibitor, underscoring its potential in a targeted therapeutic approach against malaria.
