acid esters of β-lactone derivatives structurally related to tetrahydrolipstatin (THL) and O-3841 were synthesized that inhibit human and murine diacylglycerol lipase (DAGL) activities. New ether lipid reporter compounds were developed for an in vitro assay to efficiently screen inhibitors of 1,2-diacyl-sn-glycerol hydrolysis and related lipase activities using fluorescence resonance energy transfer (FRET)

We have synthesised a series of amphiphilic spin probes containing two nitroxide-functionalised lipophilic branches connected by a disulfide group. The sensitivity of EPR spectroscopy to the interactions between the radical centres in these bisnitroxides makes it possible to monitor the thiol-disulfide exchange reaction in colloidal assemblies.

Paramagnetic amide side products (6a–g) have been isolated from the reaction mixture in the synthesis of spin‐labeledfattyacids of the doxyl type. After their hydrolysis to the corresponding acid, 7, the overall yield of spin‐labeledfattyacids is significantly increased compared with published procedures.

Flexible on the outside: The functionalstructure of the transport protein in human blood, humanserumalbumin (HSA), was characterized by distance measurements with double electron–electron resonance (DEER) spectroscopy on spin‐labeled fattyacids that are bound to HSA. The functional protein structure derived has a more rigid inner core, while the surface of the protein shows much greater structural
