  Design, synthesis, and evaluation of potential inhibitors of brassinin glucosyltransferase, a phytoalexin detoxifying enzyme from Sclerotinia sclerotiorum

  摘要：

  Sclerotinia sclerotiorum is a fungal pathogen, which causes stem rot in crucifer crops and in several other plant families resulting in enormous yield losses all over the world. Brassinin is a phytoalexin produced by crucifer plants as part of a general defense mechanism against pathogens and other forms of stress. To the great detriment of crucifers, some fungal pathogens, as for example S. sclerotiorum, can cletoxify brassinin. Detoxification of brassinin via glucosylation of the indole nitrogen is carried out by an inducible glucosyltransferase produced in S. sclcrotiorum. Because brassinin is a precursor of several phytoalexins active against S. sclcrotiorum, brassinin glucosyltransferase (BGT) is a potentially useful metabolic target to control S. sclerotiorum. Toward this end, we have designed, synthesized, and screened several brassinin analogues using both mycelial cultures and cell-free homogenates of S. sclerotiorum. A noticeable decrease in the rate of brassinin detoxification in cell cultures was observed in the presence of methyl (benzofuran-3-yl)methyl dithiocarbamate, methyl (benzofuran-2-yl)methyldithiocarbamate, methyl (indol-2-yl)methyldithiocarbamate, 3-phenylindole, 6-fluoro-3-phenylindole, and 5-fluorocamalexin. In addition, these compounds caused substantial inhibition of BGT activity (ca. 80%) in cell-free homogenates of S. sclerotiorum, while only brassinin and 3-phenylindole were transformed to the corresponding beta-D-1-glucopyranosyl products. These results indicate that, although many other glucosyltransferases appear to be produced by S. sclerotiorum in cell cultures, BGT is substrate specific. Overall these results show that selective and potent inhibitors of BGT can be developed. (c) 2007 Elsevier Ltd. All rights reserved.

  In the present investigation, two series of 2,5-disubstituted-3-imidazol-2-yl-pyrrolo[2,3-b]pyridines (2a-1) and thieno[2,3-b]pyridines (3a-1) were designed as analogs of BL 11282 (1). The in vitro glucose dependent insulinotropic activity of all the test compounds was evaluated using RIN5F cell based assay and all the test compounds showed glucose and concentration dependent insulin secretion. The in vivo antidiabetic activities of most potent compounds from each series (2c and 3c) were assessed in C57BL/6J mice. Compounds 2c and 3c showed dose dependent insulin secretion and significant glucose reduction in vivo. In general, compounds 2c and 3c were found to be equipotent at all the three different doses selected and with respect to BL 11282, both the test compounds were found to be more potent, at all the time points.
