Substituted Imidazole 4-Carboxamides as Cholecystokinin-1 Receptor Modulators

Certain novel substituted imidazole 4-carboxamides are ligands of the human cholecystokinin receptor and, in particular, are selective ligands of the human cholecystokinin-1 receptor (CCK-1R). They are therefore useful for the treatment, control, or prevention of diseases and disorders responsive to the modulation of CCK-1R, such as obesity, and diabetes.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. COA of Formula: C8H9NO2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 22013-33-8, in my other articles.

Photocatalytic decarboxylative alkenylation of alpha-amino and alpha-hydroxy acid-derived redox active esters by NaI/PPh3 catalysis

Herein, we report the photocatalytic decarboxylative alkenylation reactions of N-(acyloxy)phthalimide derived from alpha-amino and alpha-hydroxy acids with 1,1-diarylethene, and with cinnamic acid derivatives through double decarboxylation, using sodium iodide and triphenylphosphine as redox catalysts. The reaction proceeds under mild irradiation conditions with visible blue light (440 nm or 456 nm) in an acetone solvent without recourse to transition-metal or organic dye based photoredox catalysts. The reaction proceeds via photoactivation of a transiently self-assembled chromophore from N-(acyloxy)phthalimide and NaI/PPh3. Solvation plays a crucial role in the reactivity.

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 70918-54-6, help many people in the next few years.Product Details of 70918-54-6

Ultrasound-assisted synthesis and biological evaluation of 1,4-benzodioxane-2-carboxyl-amino acids and Peptides

A series of peptides containing 1,4-benzodioxane nucleus were attempted to synthesize by conventional as well as green techniques like microwave-assisted and sonication, using dicyclohexylcarbodiimide (DCC) as a coupling reagent and triethylamine as a base. Sonication has proved to be the efficient method for the synthesis of the title compounds. All the compounds were characterized by FTIR, 1H NMR and Mass spectral studies. They were evaluated for their insecticidal and anthelmintic activities. All the compounds showed moderate anthelmintic activity as compared to the standard drug mebendazole. However, the compounds exhibited potent insecticidal activity, the most potent being 1,4-benzodioxane-2-carboxyl-phenylalaninetryptophan- methyl ester as compared to the standard, chloropyrifos.

N-phenyl-4-pyrazolo[1,5-6]pyridazin-3-ylpyrimidin-2-amines as potent and selective inhibitors of glycogen synthase kinase 3 with good cellular efficacy

Glycogen synthase kinase 3 regulates glycogen synthase, the rate-determining enzyme for glycogen synthesis. Liver and muscle glycogen synthesis is defective in type 2 diabetics, resulting in elevated plasma glucose levels. Inhibition of GSK-3 could potentially be an effective method to control plasma glucose levels in type 2 diabetics. Structure-activity studies on a N-phenyl-4-pyrazolo[1,5-b]pyridazin-3-ylpyrimidin-2-amine series have led to the identification of potent and selective compounds with good cellular efficacy. Molecular modeling studies have given insights into the mode of binding of these inhibitors. Since the initial leads were also potent inhibitors of CDK-2/CDK-4, an extensive SAR was performed at various positions of the pyrazolo[1,5-b] pyridazin core to afford potent GSK-3 inhibitors that were highly selective over CDK-2. In addition, these inhibitors also exhibited very good cell efficacy and functional response. A representative example was shown to have good oral exposure levels, extending their utility in an in vivo setting. These inhibitors provide a viable lead series in the discovery of new therapies for the treatment of type 2 diabetes.

Cascade bio-hydroxylation and dehalogenation for one-pot enantioselective synthesis of optically active beta-halohydrins from halohydrocarbons

A stereoselective hydroxylation and enantioselective dehalogenation cascade reaction was developed for the synthesis of optically active beta-haloalcohols from halohydrocarbons. This cascade system employed P450 and halohydrin dehalogenase as two compatible biocatalysts, allowing a straightforward, greener and efficient access to beta-halohydrins with excellent enantioselectivities (98-99%).

Synthesis of new 2-{2,3-dihydro-1,4-benzodioxin-6-yl[(4?methylphenyl) sulfonyl]amino}-N-(un/substituted-phenyl) acetamides as alpha-glucosidase and acetylcholinesterase inhibitors and their in silico study

The aim of the present research work was to investigate the enzyme inhibitory potential of some new sulfonamides having benzodioxane and acetamide moieties. The synthesis was started by the reaction of N-2,3-dihydrobenzo[1,4]-dioxin-6-amine (1) with 4-methylbenzenesulfonyl chloride (2) in the presence of 10% aqueous Na2CO3 to yield N-(2,3-dihydrobenzo[1,4]-dioxin-6-yl)-4-methylbenzenesulfonamide (3), which was then reacted with 2-bromo-N-(un/substituted-phenyl)acetamides (6a-l) in DMF and lithium hydride as a base to afford various 2-{2,3-dihydro-1,4-benzodioxin-6-yl[(4-methylphenyl)sulfonyl] amino}-N-(un/substituted-phenyl)acetamides (7a-l). All the synthesized compounds were characterized by their IR and 1H-NMR spectral data along with CHN analysis data. The enzyme inhibitory activities of these compounds were tested against a-glucosidase and acetylcholinesterase (AChE). Most of the compounds exhibited substantial inhibitory activity against yeast a-glucosidase and weak against AChE. The in silico molecular docking results were also consistent with in vitro enzyme inhibition data.
