In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction. 2081-44-9, Name is Tetrahydro-2H-pyran-4-ol, molecular formula is C5H10O2. In a Patent，once mentioned of 2081-44-9, Computed Properties of C5H10O2
The invention relates to compounds of formula (I) wherein: either any one of G1, G2, G3, G4 and G5 is nitrogen and the other four are ?CH?, or G1, G2, G3, G4 and G5 are all ?CH?; Z is ?O?, ?NH?, ?S?, ?CH2? or a direct bond; Z is linked to any one of G1, G2, G3 and G4; n is an integer from 0 to 5; m is an integer from 0 to 3; Ra represents hydrogen or fluoro; Rb, R1 and R2 are defined herein and salt thereof, process for the preparation so such compounds, pharmaceutical compositions containing a compound of formula I or a pharmaceutically acceptable salt thereof as active ingredient and the use of a compound of formula I in the manufacture of a medicament for the production of an antiangiogenic and/or vascular permeability reducing effect in warm-blodded animals. The compounds of formula I and the pharmaceutically acceptable salts thereof inhibit the effects of VEGF, a property of value in the treatment of a number of diseases states including cancer and rheumatoid arthritis.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 2081-44-9 is helpful to your research., Computed Properties of C5H10O2
