  Diversity-Oriented Synthesis Yields a Novel Lead for the Treatment of Malaria

  摘要：

  Here, we describe the discovery of a novel antimalarial agent using phenotypic screening of Plasmodium falciparum asexual blood-stage parasites. Screening a novel compound collection created using diversity-oriented synthesis (DOS) led to the initial hit. Structure activity relationships guided the synthesis of compounds having improved potency and water solubility, yielding a subnanomolar inhibitor of parasite asexual blood-stage growth. Optimized compound 27 has an excellent off-target activity profile in erythrocyte lysis and HepG2 assays and is stable in human plasma. This compound is available via the molecular libraries probe production centers network (MLPCN) and is designated ML238.

  Despite some stereochemical dependencies, the ring-forming reactions were optimized to proceed with good to excellent yields, providing a variety of skeletons ranging in size from 8- to 14-membered rings. Scaffolds resulting from the RCM pairing reaction were diversified on the solid phase to yield a 14 400-membered library of macrolactams. Screening of this library led to the discovery of a novel class

  A build/couple/pair (B/C/P) strategy was employed to generate a library of 7936 stereochernically diverse 12-membered macrolactams. All 8 stereoisomers of a common linear amine precursor were elaborated to form the corresponding 8 stereoisomers of two regioisomeric macrocyclic scaffolds via head-to-tail cyclization. Subsequently,these 16 scaffolds were further diversified via capping of two amine functionalities on SynPhase Lanterns. Reagents used for solid-phase diversification were selected using a sparse matrix design strategy with the aim of maximizing coverage of chemical space while adhering to a preset range of physicochemical properties.

  The synthesis of a stereochemically diverse library of medium-sized rings accessible via a "build/couple/pair" strategy is described. Key aspects of the synthesis include SNAr cycloetherification of a linear amine template to afford eight stereoisomeric eight-membered lactams and subsequent solid-phase diversification of these scaffolds to yield a 6488-membered library. Screening of this compound collection in a cell-based assay for the suppression of cytokine-induced beta-cell apoptosis resulted in the identification of a small-molecule suppressor capable of restoring glucose-stimulated insulin secretion in a rat beta-cell line. The presence of all stereoisomers in the screening collection enabled preliminary determination of the structural and stereochemical requirements for cellular activity, while efficient follow-up chemistry afforded BRD0476 (probe ML187), which had an approximately 3-fold increase in activity. These results demonstrate the utility of diversity-oriented synthesis to probe discovery using cell-based screening and the importance of including stereochemical diversity in screening collections for the development of stereo/structure-activity relationships.
