substrate specificity for 5-lipoxygenase and the known stereochemical course of the reaction, a hypothetical model of the enzyme active site was developed and used to design 2 types of selective inhibitors of 5-lipoxygenase. Both inhibitor types used aromatic rings in place of (Z)-olefins of the substrate and were designed to mimic the nonpolar end of arachidonic acid. One inhibitor type used a carboxylic-acid

Die Erfindung betrifft ein saures Reinigungsmittelkonzentrat mit niedriger Viskosität, welches sich bei Verdünnung auf die Anwendungskonzentration ohne Zusatz von Verdickungsmitteln verdickt und seine Viskosität erhöht und ein Aminoxid, zumindest eine Säure sowie ein Fettaminalkoxylat enthält.
The present invention relates to a frictional power transmission belt containing an extensible layer to form a belt back surface, a compressive layer formed on one surface of the extensible layer and having a power transmission surface at least a part of which can be in contact with pulleys, and a tension member embedded between the extensible layer and the compressive layer along a belt length direction, in which at least the compressive layer is formed of a rubber composition containing a polymer component, short fibers and a surfactant and in which the short fibers contain at least short fibers of water-absorbing fibers.
