(4-Phenoxyphenylsulfonyl)methylthiirane (SB-3CT) is the selective inhibitor of matrix metalloproteinase 2 (MMP2). The inhibition mechanism of MMP2 by SB-3CT involves C-H deprotonation with concomitant opening of the three-membered heterocycle. In this study, the energetics of the deprotonation-induced ring-opening of (4-phenoxyphenylsulfinyl)methylthiirane, the sulfoxide analogue of SB-3CT, are...

The use of new and selective inhibitors of matrix metalloproteinases (MMPs) may have significant therapeutic potential in stroke patients, report US researchers. The role of MMPs, and MMP-9 in particular, has been suggested in the pathogenesis of neurological disorders, but efforts to inhibit MMP activity have been largely unsuccessful in human clinical trials, says study author Stuart A Lipton...

Polymerizations of racemic mixtures of epoxides or episulfides may lead to stereoregular polymers through a stereoselective process, and to optically active polymers through a stereoelective process that gives either atactic or isotactic polymers. Monomers that have been most studied are propylene oxide, propylene sulfide and t-butyl thiirane, and their polymerization with insoluble initiators ...
