Synthesis and quantitative structure-activity relationship of fatty acid amide hydrolase inhibitors: Modulation at the N-portion of biphenyl-3-yl alkylcarbamates

Alkylcarbamic acid biphenyl-3-yl esters are a class of fatty acid amide hydrolase (FAAH) inhibitors that comprises cyclohexylcarbamic acid 3?-carbamoylbiphenyl-3-yl ester (URB597), a compound with analgesic, anxiolytic-like and antidepressant-like properties in rat and mouse models. Here, we extended the structure-activity relationships (SARs) for this class of compounds by replacing the cyclohexyl ring of the parent compound cyclohexylcarbamic acid biphenyl-3-yl ester (URB524) (FAAH IC50 = 63 nM) with a selected set of substituents of different size, shape, flexibility, and lipophilicity. Docking experiments and linear interaction energy (LIE) calculations indicated that the N-terminal group of O-arylcarbamates fits within the lipophilic region of the substrate-binding site, mimicking the arachidonoyl chain of anandamide. Significant potency improvements were observed for the beta-naphthylmethyl derivative 4q (IC50 = 5.3 nM) and its 3?-carbamoylbiphenyl-3-yl ester 4z (URB880, IC50 = 0.63 nM), indicating that shape complementarity and hydrogen bonds are crucial to obtain highly potent inhibitors.

Synthesis of stable derivatives of cycloprop-2-ene carboxylic acid

(Chemical Equation Presented) Large-scale syntheses of 3-(cycloprop-2-en-1- oyl)oxazolidinones from acetylene and ethyl diazoacetate are described. Unlike other cyclopropenes that bear a single substitutent at C-3, these compounds are stable to long-term storage. Although the cyclopropene derivatives are unusually stable, they are reactive toward cyclic and acyclic dienes in stereoselective Diels-Alder reactions.

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 497-25-6 is helpful to your research. 497-25-6

Thermal Degradation Pathways of Aqueous Diamine CO2 Capture Solvents

Diamines have shown promise as CO2 capture solvents, yet very little is known about their pathway for thermal degradation. In this study, diamine thermal degradation was quantitatively monitored in lab-scale experiments on four aqueous diamine solvents; ethylenediamine (EDA) 1,2-propanediamine (1,2-DAP), 1,3-diaminopropane (1,3-DAP) and N-methyl-1,2-ethanediamine (N-MEDA), to gain a more comprehensive understanding of their degradation pathway(s). The major degradation products were identified by high resolution time-of-flight mass spectrometry (TOF-MS). Degradation pathways were proposed showing that the primary thermal degradation route for this class of amine are through carbamate formation followed by intermolecular cyclization to form an imidazolidinone or nucleophilic attack by a free amine to form a diamine urea.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. 497-25-6, In my other articles, you can also check out more blogs about 497-25-6

Palladium-mediated synthesis of novel meso-chiral porphyrins: Cobalt-catalyzed cyclopropanation

A series of novel meso-chiral porphyrins were effectively synthesized from reactions of 5,15-dibromo-10,20-diarylporphyrins with readily available chiral alcohols and amides via palladium-mediated C-N and C-O bond formations. Cobalt complexes of these chiral porphyrins were prepared and shown to be effective catalysts for cyclopropanation of styrene with ethyl diazoacetate under mild and practical conditions, affording the desired cyclopropane ester as a trans-dominant form in excellent yields. Due to orientation and flexibility of the chiral appendages, only low enantioselectivity was observed.

K?La?MgO as heterogeneous catalyst for synthesis of 3-(2-hydroxyethyl)-1,3-oxazolidin-2-one from diethanol amine and carbon dioxide

Cost-effective valorization of carbon dioxide into bulk and specialty chemicals using catalysis will be attractive in the foreseeable future. 1,3-Oxazolidin-2-one derivatives are one of the important classes of heterocyclic compounds which have wide applications in pharmaceutical industries due to their biological activities such as antibacterial, antimicrobial, antiseptic. Various synthetic routes are employed to prepare these compounds which include phosgenation, oxidative carbonylation, etc., which make use of polluting chemicals and homogeneous catalysts. The heterogeneous catalytic processes to synthesize these derivatives are quite limited. Thus, developing a green route which is environmental friendly is highly desirable. The current work deals with development of a heterogeneous reusable catalyst and its application to synthesize 1,3-oxazolidin-2-one derivatives using carbon dioxide as a C1 source. The fact that?no use of promoter or organic co-catalyst is made?in the current process makes the synthesis route more favorable. Pure La?MgO and K?La?MgO with different K loading (1, 3, 5, and 7?wt%) synthesized by combustion route were screened for carbonylation of diethanol amine. 5% K?La?MgO was found to be the best catalyst. The catalyst was well characterized in virgin form and after use by various analytical techniques like TEM, SEM, XRD, CO2 and NH3-TPD, BET surface area analysis. With 5% K?La/MgO, 72% conversion of diethanol amine was achieved with 100% selectivity of the desired product at optimum conditions, i.e., 150?C, 5?wt% K?La/MgO catalyst loading of 0.02?g/cm3 and 2.0?MPa CO2 pressure. Reaction mechanism was proposed and kinetic model developed. The apparent activation energy was calculated as 18.76?kcal/mol. The catalyst was robust and recyclable. The process is clean and green.

Arylboronic acid-catalyzed direct condensation of carboxylic acids with ureas

The first example of the catalytic direct condensation of carboxylic acids with ureas to give N-acylureas, N,N?-diacyl-2-imidazolidones, and poly(N,N?-diacyl-2-imidazolidone)s is described. Arylboronic acids bearing electron-withdrawing substituents are highly effective as catalysts for this condensation. Furthermore, a new and efficient one-pot procedure for the conversion of carboxylic acids and urea to nitriles via N-acylurea intermediates was accomplished by using arylboronic acid and rhenium(VII) oxo complexes as hybrid catalysts.
