Diversity-Oriented Synthesis-FacilitatedMedicinalChemistry: Toward the Development of Novel Antimalarial Agents

摘要

Here, we describe medicinal chemistry that was accelerated by a diversity-oriented synthesis (DOS) pathway, and in vivo studies of our previously reported macrocyclic antimalarial agent that derived from the synthetic pathway. Structure–activity relationships that focused on both appendage and skeletal features yielded a nanomolar inhibitor of P. falciparum asexual blood-stage growth with improved solubility and microsomal stability and reduced hERG binding. The build/couple/pair (B/C/P) synthetic strategy, used in the preparation of the original screening library, facilitated medicinal chemistry optimization of the antimalarial lead.
