Validation of solvent proteome profiling for antimalarial drug target deconvolution.

ABSTRACT: Malaria remains a global health threat, with rising drug resistance accelerating the urgent need for new therapeutics. Target elucidation is a critical step in antimalarial drug discovery, enabling a deeper understanding of the molecular mechanisms of action of both existing and novel compounds. This study validates solvent-induced proteome profiling (SPP) as a proteomics-based approach for identifying drug-protein interactions in Plasmodium falciparum. SPP detects shifts in protein stability induced by ligand binding, allowing the identification of drug target/s without the need for compound modifications. Here, we successfully generated solvent denaturation curves for the P. falciparum proteome, and demonstrated the utility of SPP with five antimalarial compounds: pyrimethamine, atovaquo
