electrochemistry, the conversion of arylhalides to sulfinates using an inexpensive Ni catalyst at room temperature is reported. The use of SO2 stock solution at controlled concentration represents a convenient sulfur source. The sulfinate intermediates can be derivatized into sulfonyl fluorides, sulfonamide, and sulfone in a one-pot fashion. This reaction exhibits a broadsubstratescope and can be easily scaled

Disclosed is a composition that synergistically prevents proteolysis or modification of peptides in sampled biological fluids using sulfonyl fluoride family protease inhibitors at high concentrations combined with at least one additional protease inhibitor of a different type, preferably a broad spectrum protease inhibitor, and a chelator. A preferred embodiment uses AEBSF at 10mM, Benzamidine at 20mM and EDTA as the chelator. The disclosed composition may be combined with other protease inhibitors to further modulate its specificity, for instance to additionally target acidic proteases. Additional protease inhibitors, reducing agents, stabilizers and buffering agents may be combined with the disclosed compositions in devices for sampling or testing biological fluids for levels of peptides of interest, or methods therefore. The disclosed devices, compositions and methods are of particular use in sampling and testing for the level of natriuretic peptides.

This method for inhibiting protease in a biological sample containing pancreatic juice components inhibits protease enzyme activity in the biological sample by adding at least one type of protease inhibitor having a sulfonyl fluoride group to the biological sample containing pancreatic juice components. In addition, this protease inhibitor for a biological sample containing pancreatic juice components is a compound having a sulfonyl fluoride group, has protease inhibitory activity, and is added to a biological sample containing pancreatic juice components in order to inhibit protease present in the biological sample. Moreover, this kit for preserving a biological sample containing pancreatic juice components contains at least one type of protease inhibitory having a sulfonyl fluoride group, and is used to store a biological sample containing pancreatic juice components.
Stabilized compositions of natriuretic peptides comprise the peptide and an effective stabilizing amount of (i) an alkyl or aryl sulfonyl fluoride protease inhibitor, or (ii) benzamidine:
