Tyropeptins A and B, new proteasome inhibitors produced by Kitasatospora sp. MK993-dF2. II. Structure determination and synthesis.

The structures of tyropeptins A and B, new proteasome inhibitors produced by Kitasatospora sp. MK993-dF2, were determined by analysis of various NMR experiments. The 1H and 13C NMR of tyropeptins were complicated due to the presence of an aldehyde group. Therefore, tyropeptins were converted to their alcohols by sodium borohydride. These alcohol derivatives gave assignable NMR spectra. The ster...

Inhibition of proteasome activity by tyropeptin A in PC12 cells.

Tyropeptin A, a potent proteasome inhibitor not reported before, was produced by Kitasatospora sp. MK993-dF2. In this study, we investigated the effects of tyropeptin A on proteasome activity in PC12 cells. Tyropeptin A inhibited the intracellular proteasome activity in a dose-dependent way and seemed to cause neurite outgrowth. As expected, ubiquitinated proteins that should be substrates for ...

Maillard reaction inhibitors produced by Paecilomyces sp.

Maillard reaction inhibitors could be useful therapeutics for diabetes and other age-related diseases. We isolated for the first time 4-O-demethylsilvaticol (1) and (-)-mitorubrin (2) as Maillard reaction inhibitors from Paecilomyces sp. 3193B. Among the isolated inhibitors, 2 showed most potent inhibitory effect by an SDS-PAGE assay on cross-linked protein formation and by a fluorescent assay ...

Novel cytokine production inhibitors produced by a basidiomycete, Marasmiellus sp.

New cytokine production inhibitors, CJ-14,877 (I) and CJ-14,897 (II), were isolated from the fermentation broth of a basidiomycete, Marasmiellus sp. CL21624. Their structures were determined to be methyl-(7S,8S)-5-(7,8-dihydroxypropyl)pyridine-2-carboxylate and methyl-(7S,8S)-5-(8-acetoxy-7-hydroxypropyl)pyridine-2-carboxylate [corrected], respectively, by spectroscopic analyses. These compound...
