yields using the Aza-Michael-type addition of various amines to vinyl compounds catalysed by a supported ionic liquid incorporating an anionic heteropoly acid. Different catalysts, including Lewisacids, Brønsted acids and heteropoly acids were investigated in which heteropoly acids having dual Brønsted and Lewisacid characteristics were excellent catalysts. The ionic liquid incorporating a polytungstate
The present disclosure relates to a class of mammalian heat shock factor (HSF) inhibitors, to pharmaceutical compositions comprising these inhibitors as well as to methods for using the inhibitors. The inhibitors inhibit stress-induced expression from heat shock gene promoters. Furthermore, the inhibitors are cytotoxic to a variety of human cancer cells types.
