In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Recommanded Product: 497-25-6, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 497-25-6, name is Oxazolidin-2-one. In an article，Which mentioned a new discovery about 497-25-6
N-Acylethanolamine-hydrolyzing acid amidase (NAAA) is a lysosomal enzyme that catalyzes the hydrolysis of endogenous fatty acid ethanolamides (FAEs), such as N-palmitoylethanolamide (PEA). PEA exhibits anti-inflammatory and analgesic activities by engaging peroxisome proliferator-activated receptor alpha (PPAR-alpha). Preventing PEA degradation by inhibition of NAAA has been proposed as a novel strategy for the treatment of inflammation and pain. In the present study, we reported the discovery of the oxazolidone derivative as a novel scaffold for NAAA inhibitors, and studied the structure-activity relationship (SAR) by modification of the side chain and terminal lipophilic substituents. The results showed that the link chain length of C5, straight and saturated linkages were the preferred shape patterns for NAAA inhibition. Several nanomolar NAAA inhibitors were described, including 2f, 3h, 3i and 3j with IC50 values of 270 nM, 150 nM, 100 nM and 190 nM, respectively. Enzymatic degradation studies suggested that 2f inhibited NAAA in a selective, noncompetitive and reversible pattern. Moreover, 2f showed high anti-inflammatory and analgesic activities after systemic and oral administration.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 497-25-6, help many people in the next few years.name: Oxazolidin-2-one
