REGIOSELECTIVE SYNTHESIS OF SUBSTITUTED PHTHALIDES VIA INTRAMOLECULAR “DIENE-REGENERATIVE” DIELS-ALDER REACTION OF 2-PYRONES

Some 2-pyrone-6-carboxylates bearing appropriate dienophiles in ester moieties underwent “diene-regenerative” Diels-Alder reaction to afford the dihydrophthalides, which were aromatized to phthalide derivatives in the presence of palladium-charcoal.In these reactions the substituents at 4 or 7-position of phthalides arose from those on yhe dienophile moieties in the starting 2-pyrones.

Discovery of a Novel Class of Negative Allosteric Modulator of the Dopamine D2 Receptor Through Fragmentation of a Bitopic Ligand

Recently, we have demonstrated that N-((trans)-4-(2-(7-cyano-3,4-dihydroisoquinolin-2(1H)-yl)ethyl)cyclohexyl)-1H-indole-2-carboxamide (SB269652) (1) adopts a bitopic pose at one protomer of a dopamine D2 receptor (D2R) dimer to negatively modulate the binding of dopamine at the other protomer. The 1H-indole-2-carboxamide moiety of 1 extends into a secondary pocket between the extracellular ends of TM2 and TM7 within the D2R protomer. To target this putative allosteric site, we generated and characterized fragments that include and extend from the 1H-indole-2-carboxamide moiety of 1. N-Isopropyl-1H-indole-2-carboxamide (3) displayed allosteric pharmacology and sensitivity to mutations of the same residues at the top of TM2 as was observed for 1. Using 3 as an “allosteric lead”, we designed and synthesized an extensive fragment library to generate novel SAR and identify N-butyl-1H-indole-2-carboxamide (11d), which displayed both increased negative cooperativity and affinity for the D2R. These data illustrate that fragmentation of extended compounds can expose fragments with purely allosteric pharmacology.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. 496-41-3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 496-41-3, in my other articles.

Synthesis of alpha-enaminones from cyclic ketones and anilines using oxoammonium salt as an oxygen transfer reagent

A convenient and straightforward transformation of cyclic ketones with anilines at room temperature has been developed using oxoammonium salt TEMPO+PF6- as an oxidant. This method enabled the synthesis of a broad range of alpha-enaminones. The 18O-labeling experiment demonstrated that oxoammonium salt served as the oxygen transfer reagent.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 66826-78-6 is helpful to your research. 66826-78-6

Ultrasound mediated, green innovation for the synthesis of polysubstituted 1,4-dihydropyridines

An elegant, atom efficient protocol via a one-pot four-component cyclocondensation reaction of aromatic aldehydes, malononitrile, acetylenedicarboxylates and arylamines catalyzed by copper(I) iodide in aqueous medium under ultrasound irradiation has been developed for the synthesis of a series of novel pharmacologically interesting polysubstituted 1,4-dihydropyridines. In comparison with the reported methods, our approach is expedient and offers several advantages such as: a shorter reaction time, excellent yields, milder conditions, convenience and environmental benignity. We have herein successfully demonstrated the utility of sonication in a multicomponent reaction (MCR), which exhibits a better functional group tolerance, and straightforward product isolation and purification by precipitation.

Identification of benzothiophene amides as potent inhibitors of human nicotinamide phosphoribosyltransferase

Nicotinamide phosphoribosyltransferase (Nampt) is an attractive therapeutic target for cancer. A Nampt inhibitor with novel benzothiophene scaffold was discovered by high throughput screening. Herein the structure-activity relationship of the benzothiophene Nampt inhibitor was investigated. Several new inhibitors demonstrated potent activity in both biochemical and cell-based assays. In particular, compound 16b showed good Nampt inhibitory activity (IC50= 0.17 muM) and in vitro antitumor activity (IC50= 3.9 muM, HepG2 cancer cell line). Further investigation indicated that compound 16b could efficiently induce cancer cell apoptosis. Our findings provided a good starting point for the discovery of novel antitumor agents.
