Abstract: | We designed some novel diphenyl ethers and determined their binding energies for Enoyl-Acyl Carrier Protein Reductase (ENR) of Plasmodium falciparum using Autodock. Out of these, we synthesized the promising compounds and tested them for their inhibitory activity against ENRs of P. falciparum as well as Escherichia coli. Some of these compounds show nanomolar inhibition of PfENR and low micromolar inhibition of EcENR. They also exhibit low micromolar potency against in vitro cultures of P. falciparum and E. coli. The study of structure-activity relationship of these compounds paves the way for further improvements in the design of novel diphenyl ethers with improved activity against purified enzyme and the pathogens. |
