Lipids play critical roles in cell biology, often through direct interactions with proteins. We recently described the use of photoreactive lipid probes combined with quantitative mass spectrometry to globally map lipid-protein interactions, and the effects of drugs on these interactions, in cells. Here, we investigate the broader potential of lipid-based chemical proteomic probes for determining the cellular targets of biologically active small molecules, including natural product derivatives and repurposed drugs of ill-defined mechanisms. We identify the prostaglandin-regulatory enzyme PTGR2 as a target of the anti-diabetic hops derivative KDT501 and show that miconazole—an anti-fungal drug that attenuates disease severity in preclinical models of multiple sclerosis—inhibits SGPL1, an enzyme that degrades the signaling lipid sphingosine-1-phosphate, drug analogues of which are used to treat multiple sclerosis in humans. Our findings highlight the versatility of lipid-based chemical proteomics probes for mapping small molecule-protein interactions in human cells to gain mechanistic understanding of bioactive compounds.
