In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. 653-37-2, Name is 2,3,4,5,6-Pentafluorobenzaldehyde, molecular formurla is C7HF5O. In a document, author is Yamakuma, Michiko, introducing its new discovery. Recommanded Product: 2,3,4,5,6-Pentafluorobenzaldehyde.
1-HYDROXYETHYLHALENAQUINONE: A NEW PROTEASOME INHIBITOR FROM THE MARINE SPONGE XESTOSPONGIA SP.
A new halenaquinone derivative, 1-hydroxyethylhalenaquinone (1), was isolated from the marine sponge Xestospongia sp. as a proteasome inhibitor together with three known compounds, halenaquinone (2) and 3-ketoadociaquinones A (3) and B (4). 1-Hydroxyethylhalenaquinone (1) was the first halenaquinone derivative containing an alkyl group at the keto-furan C-1 position. Compounds 1 and 2 inhibited the chymotrypsin-like activity of the proteasome with IC50 values of 0.19 and 0.63 mu M, respectively, whereas 3 or 4, each containing a thiomorpholine 1,1-dioxide moiety, scarcely inhibited its activity, even at a concentration of 5 mu M.
The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. Interested yet?
