Application of 805250-17-3, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.805250-17-3, Name is Methyl 2-(6-hydroxy-2,3-dihydrobenzofuran-3-yl)acetate, molecular formula is C11H12O4. In a article，once mentioned of 805250-17-3

The free fatty acid receptor 1 (FFA1/GPR40) is a novel antidiabetic target based on particular mechanism in enhancing glucose-stimulated insulin secretion. Most of reported FFA1 agonists, however, have been suffered from relatively high lipophilicity and molecular weight. Aiming to develop potent agonists with improved physicochemical property, 25 compounds containing triazole scaffold and various carboxylic acid fragments were synthesized via the click chemistry. Among them, the optimal lead compound 26 with relatively low lipophicity (Log D7.4 = 1.95) and molecular weight (Mw = 391.78) exhibited a considerable FFA1 agonistic activity (36.15%). In addition, compound 26 revealed a significant improvement in the glucose tolerance with a 21.4% and 14.2% reduction of glucose AUC0?2hin normal ICR mice and type 2 diabetic C57BL/6 mice, respectively. All of these results demonstrated that compound 26 was considered to be a promising lead compound suitable for further optimization.

Synthetic Route of 10242-12-3, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 10242-12-3, 5-Nitrobenzofuran-2-carboxylic acid, introducing its new discovery.

A convenient way to introduce aryl functionalization in the 6-position of 4-quinolones is developed via selective bromination and subsequent arylation by Suzuki cross-coupling. Ethyl 4-quinolone 3-carboxylates were subjected to selective bromination at C-6 followed by arylation under microwave irradiation that yielded the desired cross-coupling products within 5 minutes. This approach can expediently be used for library synthesis of the aryl functionalized 4-quinolone derivative, an important class of biologically active compounds.
