Synthesis and evaluation of various heteroaromatic benzamides as analogues of ?ylidene-benzamide cannabinoid type 2 receptor agonists

The CB2 receptor is an attractive target for the treatment of a wide range of diseases and pathological conditions. Compounds that selectively activate the CB2 receptor are desirable as this avoids CB1-mediated psychoactive effects. Heteroarylidene-benzamides have demonstrated efficacy as selective CB2 receptor agonists. We aimed to expand the structure-activity relationship studies of this series of compounds by investigating the heteroaromatic core via the synthesis and in vitro evaluation of a small library of various heteroaromatic benzamide analogues. As heteroaromatic amides are privileged scaffolds in drug design, methods to synthesise them are of interest. Concise and reliable synthetic strategies were developed to access these novel analogues. The ?ylidene-benzamide moiety is shown to be essential for CB activity as all amide derivatives exhibit no functional activity at either CB2 or CB1 receptors.

Acid-Catalyzed Hydrolyses of 2-Alkoxytetrahydropyrans: Evidence for the Changeover from an A1 to an ASE2 Mechanism

Kinetics of the acid-catalyzed hydrolyses of 2-ethoxy-, 2-methoxy-, 2-(2-methoxyethoxy)-, 2-(2-chloroethoxy)-, 2-(propargyloxy)-, and 2-(2,2,2-trifluoroethoxy)tetrahydropyran have been studied in aqueous acidic solutions.The hydrolysis of 2-(2,2,2-trifluoroethoxy)tetrahydropyran occurs by an ASE2 mechanism and exhibits the requisite general acid catalysis.While this mechanism cannot be strictly excluded for the hydrolysis of 2-ethoxytetrahydropyran, the lack of observation of general acid catalysis and the manner in which enthalpies and entropies of activation change as the 2-alkoxy group is changed strongly suggest an A1 mechanism.A rationale is presented for using entropies of activation as an indication of changeover from an A1 to an ASE2 mechanism, based on the tetrahydropyran series (where such a changeover appears to occur) and on the benzaldehyde series (where hydrolyses occur by an ASE2-like mechanism).It is observed that in order for a physical organic model to closely resemble the hydrolysis of a natural substrate at the active site of an enzyme (e.g., lysozyme), the leaving group must contain electronegative groups: aryloxy, 2,2,2-trifluoroethoxy, and 2-propargyloxy all seem adequate.This structural feature is much more important than inherent reactivity; thus 2-(2,2,2-trifluoroethoxy)tetrahydropyran is a better reaction model than methyl glucosides.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 5631-96-9, you can also check out more blogs about5631-96-9

5-Sulfonyl-benzimidazoles as selective CB2 agonists

A novel series of benzimidazole CB2-receptor agonists was synthesized and the structure-activity relationship explored. The results showed agonistic activities with an EC50 up to 0.5 nM and excellent selectivity (>4000-fold) over the CB1 receptor. The size of the substituent on the 2-position determined the level of agonism, ranging from inverse agonism to partial agonism to full agonism, which was more pronounced for the rat CB2 receptor. A wide variation of sulfonyl substituents at the benzimidazole 5-position was tolerated, which was used to optimize the drug-like properties. This resulted into lead compound 14j that can be used to investigate the potential of a selective, peripherically acting CB2 agonist. The in vitro profile of key compounds is displayed using pie bar charts (VlaaiVis).

An efficient and general synthesis of primary amines by ruthenium-catalyzed amination of secondary alcohols with ammonia

Atom efficiency and selectivity are the key features of the first homogeneously catalyzed amination of secondary alcohols with ammonia to give the corresponding primary amines (see scheme). This novel amination method relies on the commercially available catalyst [Ru3(CO)12]/ cataCXium PCy and does not require any additional source of hydrogen.

Proton chemical shifts in NMR. Part 12.1 Steric, electric field and conformational effects in acyclic and cyclic ethers

The proton resonance spectra of tetrahydropyran, at room temperature and -85C where the ring inversion is slow on the NMR timescale, 2-methoxy-, 3-methyl- and several 4-substituted tetrahydropyrans, 2-methyl-1,3-dioxolane and the rigid cyclic ethers 7-oxabicyclo[2.2.1]heptane and 1,8-cineole heve been recorded and completely analysed. These results together with literature data on acyclic and cyclic ethers (1,3- and 1,4-dioxane, dioxolane, 4-oxa-5alpha-androstane etc.) have allowed the determination of the oxygen substituent chemical shifts (SCS) in these systems. This data set consisting of 78 proton chemical shifts in 17 compounds has been used to test the application of a previous theoritical model of proton chemical shifts to these compounds. It is shown that the model gives a very good account of the proton chemical shifts in these systems. The ether oxygen SCS are due to both steric and electrostatic terms, the steric term predominating at short distances (e.g. in the 1,3-diaxial interactions in methoxycyclohexanes). Conformational isomerism in these compounds has also been investigated. Low temperature NMR gave DeltaG (eq-ax) + 1.0 kcal mol-1 for 4 hydroxy-THP. Analysis of the couplings in the CHCH2OH side chain of 2-(hydroxymethyl)-THP has shown that the preferred conformer is gt in both chloroform and acetone solvents.

Short communication: Compositional characteristics and aromatic profile of caciotta cheese obtained from Friesian cows fed with a dietary supplementation of dried grape pomace

The aim of the present work was to explore the chemical-sensorial characteristics and aromatic profile of caciotta cheese obtained from Friesian cows fed a diet enriched with grape pomace obtained from red grape (Vitis vinifera L.). Dietary enrichment with grape pomace influenced the production of caciotta cheeses in interesting ways from a compositional point of view, as cheese samples were rich in polyphenols, giving a high antioxidant potential. From a biochemical standpoint, we noted a slight decrease of proteolysis during ripening, whereas, according to the analysis of volatile compounds, lipolysis was the most relevant phenomenon in samples. The presence of bioactive compounds also modified the fatty acid profile of milk and cheese, leading to an increase in concentration of linoleic, vaccenic, and rumenic acids. No significant variations were found in the sensory profile. These results showed the potential of dietary grape pomace intake to influence the chemical-nutritional and nutraceutical properties of cow milk and cheeses, whose introduction to the market could be attractive to consumers, providing interesting implications for the dairy industry. Finally, our results identified of a valid use of an agro-industrial by-product, grape pomace, whose disposal generally presents economic and environmental problems.
