Within this study, in order to establish the precise PD protein interactome in parasites, we created a class of (pro-)activity-based protein profiling probes (ABPP) as precursors of photoreactive benzophenone-like probes determined by the skeleton of PD metabolites (PDO) generated in a cascade of redox reactions. Beneath UV-photoirradiation, we clearly demonstrate that benzylic oxidation of 3-benzylmenadione 11 produces the 3-benzoylmenadione probe 7, allowing investigation of your proof-of-concept of the ABPP technique with 3benzoylmenadiones 7-10. The synthesized 3-benzoylmenadiones, probe 7 with an alkyne group or probe 9 with -NO2 in para position of the benzoyl chain, had been identified to become the most efficient photoreactive and SMYD2 custom synthesis clickable probes. Within the presence of several H-donor partners, the UV-irradiation with the photoreactive ABPP probes generates various adducts, the expected “benzophenone-like” adducts (pathway 1) as well as “benzoxanthone” adducts (via two other pathways, 2 and three). Making use of each human and Plasmodium falciparum glutathione reductases, 3 protein ligand binding web pages have been identified following photolabeling with probes 7 or 9. The photoreduction of 3-benzoylmenadiones (PDO and probe 9) advertising the formation of each the corresponding benzoxanthone plus the derived enone may very well be replaced by the glutathione reductase-catalyzed reduction step. In specific, the electrophilic character with the benzoxanthone was evidenced by its capability to alkylate heme, as a relevant event supporting the antimalarial mode of action of PD. This operate delivers a proof-of-principle that (pro-)ABPP probes can create benzophenone-like metabolites enabling optimized activity-based protein profiling conditions that could be instrumental to analyze the interactome of early lead antiplasmodial 3-benzylmenadione.
