Background: A variety of medications are administered to the intra-articular space for the relief of joint pain. While amide-type local anesthetics have been extensively studied, there is minimal information regarding the potential chondrotoxicity of nonsteroidal anti-inflammatory drugs (NSAIDs) and opioid medications. Purpose: To investigate the in vitro chondrotoxicity of single-dose equivalent concentrations of ketorolac, morphine, meperidine, and fentanyl on human chondrocytes. Study Design: Controlled laboratory study. Methods: Human cartilage was arthroscopically harvested from the intercondylar notch and expanded in vitro. Gene expression of cultured chondrocytes before treatment was performed with quantitative polymerase chain reaction for type I collagen, type II collagen, aggrecan, and SOX9. Chondrocytes were then exposed to 0.01%, 0.02%, and 0.04% morphine sulfate; 0.3% and 0.6% ketorolac tromethamine; 0.5%, 1.0%, and 1.5% meperidine hydrochloride; 0.0005% and 0.001% fentanyl citrate; and saline. A custom bioreactor was used to constantly deliver medications, with the dosage of each medication and the duration of exposure based on standard dose equivalents, medication half-lives, and differences in the surface area between the 6-well plates and the native joint surface. After treatment, a live/dead assay was used to assess chondrocyte viability and if minimal cell death was detected. A subset of samples after treatment was maintained to analyze for possible delayed cell death. Results: All tested concentrations of ketorolac and meperidine caused significantly increased cell death versus the saline control, demonstrating a dose-response relationship. The morphine and fentanyl groups did not show increased chondrotoxicity compared with the saline group, even after 2 weeks of additional culture. Conclusion: In vitro exposure of chondrocytes to single-dose equivalent concentrations of either ketorolac or meperidine demonstrated significant chondrotoxicity, while exposure to morphine or fentanyl did not lead to increased cell death.

Electric Literature of 146374-27-8, Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 146374-27-8, Name is 2-Methylpropane-2-sulfinamide, SMILES is CC(C)(C)[S](=O)N, belongs to amides-buliding-blocks compound. In a article, author is Lu, Ningyue, introduce new discover of the category.

The present research describes the synthesis, characterization, in vitro biological and docking evaluation of N,N’-(ethane-1,2-diyl)bis(benzamides) (3a-3j). Consequently, in in vitro hRBCs hemolysis assay, only the bis-amide (3d) induced 52.4% hemolysis at higher concentration (1000 mu g/mL) that decreased drastically with concentration (250 mu g/mL) to 27.9% (CC50 = 400.41). Similarly, the tested bis-amide (3j) was found to be the least toxic with 7.8% hemolysis at higher concentration (1000 mu g/mL) that gradually decreases to 6.1% (CC50 = 19,347.83) at lower concentration (250 mu g/mL). Accordingly, the tested bis-amides were found to be highly biocompatible against hRBCs at higher concentrations with much higher CC50 values (> 1000 mu g/mL). The biocompatible bis-amides (3a-3j) were subjected to in vitro DNA ladder assay to analyze their apoptotic potential. The results obtained suggest the tested bis-amides (3a-3j) are highly degradative toward DNA causing the appearance of more than one bands or complete degradation of DNA except (3a), (3c), (3i) and (3 g). Moreover, the synthesized bis-amides (3a-3j) were tested in in vitro antileishmanial assay to unveil their leishmaniacidal potential. The results obtained clearly indicated that some of the tested bis-amides displayed good dose dependent response. The tested bis-amides were highly active at higher concentration (1000 mu g/mL) against the leishmanial promastigotes and their % inhibitory potential decreased drastically with concentration (250 mu g/mL). Consequently, at higher concentration (1000 mu g/mL), the bis-amide (3f) caused 85% inhibition and was ranked as the most effective leishmaniacidal bis-amides followed by the bis-amide (3 g) with 73.54% inhibition of leishmanial promastigotes. However, in terms of their IC50 values, the best leishmaniacidal potential was displayed by the bis-amide (3f) followed by (3b), (3j) and (3 g) with IC50 values increasing in the order of 633.16, 680.22, 680.22 and 712.93 mu g/mL, respectively. Molecular docking studies revealed that bis-amides having electron-donating groups showed good binding potential against antileishmanial target. [GRAPHICS] .

The removal of ester and amide groups is of fundamental significance in organic syntheses. Under noncatalytic conditions, hydride sources are chiefly used for their reduction. Recently developed Ni-catalyzed one-pot reductive activation of esters and amides followed by tandem C-CO bond cleavage-decarbonylation facilitates their cleavage to aromatic hydrocarbons. Isolation and characterization of key reaction intermediates provide insight into this acyl C-O bond activation pathway.

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 84358-13-4 is helpful to your research. Recommanded Product: Boc-Inp-OH.

The low aqueous solubility of most hydrophobic medications limits their oral absorption. An approach to solve this problem is to make a drug-polymer association. Herein, we investigated the association between rafoxanide (RAF), a surface-active, poorly water-soluble drug, with a commercial hydrophilic polymer povidone. We found that the association is a function of medium composition and could only take place in polar media, such as water. The association is favored by the hydrogen-bond formation between the amide group in RAF and the carbonyl group in povidone. In addition, the association is also favored by the self-association of RAF through pi-pi interaction between the benzene rings in adjacent RAF molecules. Two-dimensional nuclear magnetic resonance has been applied to investigate the interactions and has confirmed our hypotheses. Geometry optimization confirmed that RAF exists primarily in the antiparallel configuration in the RAF aggregates. This study provides critical information for designing suitable drug-vehicle complexes and engineering the interactions between them to maximize the oral absorption. Our results shed light on drug design and delivery, drug molecule structure-functionality enhancement toward interaction engineering.

Thermal degradation under wet conditions is considered as an important aging mechanism in polyamide 6,6 (PA 6,6). The effect of water on thermal degradation of amorphous PA 6,6 is investigated at relatively low temperatures, varying from 1000 to 2000 K, using reactive force field molecular dynamics (MD) and collective variable-driven hyperdynamics simulations. The simulation of the related long-term chemical reactions is made possible thanks to the self-learning accelerated MD concept of hyperdynamics in combination with the corresponding accurate reproduction of the correct dynamics, consistent with unbiased MD simulations. The kinetics of cleavage reactions of the amide bonds in the backbone of the polymer chains, responsible for the thermal degradation of the polymer, is studied, and the influence of water content on the activation energy and pre-exponential factor of the cleavage reactions is explored. The results show that activation energy and pre-exponential factor are in agreement with experimental data. The proposed simulation framework not only estimates kinetic properties of thermal degradation that are consistent with experimental observations but also provides a predictive tool for studying long-term thermal degradation of PA 6,6.

Two brominated bisamides were developed by this protocol. Compounds were synthesized either by 4-bromobenzoyl chloride and ethylenediamine or by ortho-phenylenediamine. The choice of the diamine led to the desired products, which were characterized by IR, H-1 NMR, C-13 NMR and XRD techniques. Compounds were applied to the Suzuki coupling. They were efficient for bromides with activating and deactivating substituent groups. In the reaction performed at low temperature and in short time, with yields over 95%, it was fundamental to choose the palladium source. (C) 2018 Published by Elsevier B.V.

It is textbook knowledge that carboxamides benefit from increased stabilisation of the electrophilic carbonyl carbon when compared to other carbonyl and carboxyl derivatives. This results in a considerably reduced reactivity towards nucleophiles. Accordingly, a perception has been developed of amides as significantly less useful functional handles than their ester and acid chloride counterparts. However, a significant body of research on the selective activation of amides to achieve powerful transformations under mild conditions has emerged over the past decades. This review article aims at placing electrophilic amide activation in both a historical context and in that of natural product synthesis, highlighting the synthetic applications and the potential of this approach.

Facile and convenient synthetic approaches towards pharmaceutically important regioisomeric N-alkyl substituted 3-methylene-3,4-dihydroquinoxalin-2(1H)-ones have been developed. Various approaches to the target compounds were tested and compared. Products having bulky N-4-propyl substituent were found to exist in two forms in solutions due to solvent-dependent rotational processes in 2-oxoethylidene moiety, which is of interest for construction of optical, electronic, and other functional materials. The proposed procedures proceed in a highly regioselective manner under mild conditions, and the products are isolated without usage of column chromatography.
