Pantothenamides are potent growth inhibitors of the malaria parasite Plasmodium falciparum. Their clinical use is, however, hindered due to the ubiquitous presence of pantetheinases in human serum, which rapidly degrade pantothenamides into pantothenate and the corresponding amine. We previously reported that replacement of the labile amide bond with a triazole ring not only imparts stability toward pantetheinases, but also improves activity against P. falciparum. A small library of new triazole derivatives was synthesized, and their use in establishing structure-activity relationships relevant to antiplasmodial activity of this family of compounds is discussed herein. Overall it was observed that 1,4-substitution on the triazole ring and use of an unbranched, one-carbon linker between the pantoyl group and the triazole are optimal for inhibition of intraerythrocytic P. falciparum growth. Our results imply that the triazole ring may mimic the amide bond with an orientation different from what was previously suggested for this amide bioisostere.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 71432-55-8, in my other articles.

Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 2419-56-9, Name is H-Glu(OtBu)-OH. In a document, author is Kanega, Ryoichi, introducing its new discovery. SDS of cas: 2419-56-9.

Amide function is very important in both organic and medicinal chemistry. Benzamides can be obtained in good to high yields by reaction of benzoin, primary or secondary amines, molecular oxygen and electrogenerated superoxide anion (obtained with galvanostatic method). The advantage of using electrogenerated superoxide anion is related to its counterion, the tetraethylammonium cation, which is not tightly bound to the anion and thus renders superoxide highly reactive also in the absence of additives (necessary when using KO2). The reaction conditions are very mild and only 0.5 F/mol are necessary to obtain good yields in benzamides. This work points out that benzamides can be obtained also starting from deoxybenzoin and benzil, via C-C bond cleavage, with yields which depend on the charge amount. A mechanistic hypothesis (in part supported by the literature and by voltammetric studies) is reported, which allows to explain the formation of byproducts and to define the role of oxygen and superoxide anion.

We recently reported a series of naphthofuranic compounds as constrained agomelatine analogues. Herein, in order to explore alternative ethyl amide side chain rigidification, naphthocyclopentane and quinolinocyclopentane derivatives with various acetamide modulations were synthesized and evaluated at both melatonin (MT1, MT2) and serotonin (5-HT2c) receptors. These modifications has led to compounds with promising dual affinity and high MTs receptors agonist activity. Enantiomeric separation was then performed on selected compounds allowing us to identify levogyre enantiomers (-)-17g and (-)-17k as the highest (MT1 MT2)/5-HT2c dual ligands described nowadays.

This research demonstrates the effect of some amide compounds (1 and 2) as corrosion inhibitors on C-steel in 1.0 M of hydrochloric solutions utilizing mass reduction studies, electrochemical [potentiodynamic (PP), AC impedance measurements (EIS), electrochemical frequency modulation] techniques, and surface checks were used to illustrate the importance of amide compounds to the corrosion protection process of C-steel. The tests displayed that the inhibition efficiency (IE%) augmented with increase in amide dose but reduced with growth of temperature. The highest inhibition efficiency is 99% for compound (1) and 98.8% for compound (2) at maximum dose tested (50 mu M) by polarization method. PP data show that these compounds affect both cathodic and anodic processes (i.e. mixed type) and were adsorption on the carbon steel obeying Langmuir adsorption isotherm. The EIS results indicate that the changes in impedance parameters are related to the adsorption of amides on the alloy surface. Scanning of electron microscopy, energy transmitted X-ray-Atomic force microscopy studied the morphology of inhibited C-steel. [GRAPHICS] .

The aminolysis of ethyl acetate was promoted significantly via continuous reaction in a tubular reactor. N-propylacetamide was thus synthesized without presence of solvent and catalyst. The optimum conditions were obtained as follows: the reaction temperature is 218 degrees C, the reaction pressure is 3.5 MPa, the molar ratio (ethyl acetate: N-propylamine) is 1:1, and the residence time is 350 min. Accordingly, the conversion of ethyl acetate is up to 94.8%. Furthermore, the kinetics of the rapid reaction stage (when the conversion of ethyl acetate is 20%-80%) can be expressed as lnk = -4629.44 1/T + 2.1366, and the apparent activation energy is E-a = 38489 J.mol(-1).

The solvation parameter model is used to construct a system map for the retention of volatile organic compounds on the ionic liquid stationary phase tri(tripropypphosphoniumhexanamido)triethylamine bis(trifluoromethylsulfonyl)imide (SLB-IL76) over the temperature range 80-240 degrees C. The SLB-IL76 stationary phase is moderately cohesive and strongly dipolar/polarizable and hydrogen-bond basic but only a weak hydrogen-bond acid. Electron lone pair interactions are weak and make only a minor contribution to the retention mechanism. The separation properties of SLB-IL76 highlight the difficulty of designing new stationary phases from ion structures as the presence of amide groups in the cation don’t seem to contribute significantly to the hydrogen-bond acidity of SLB-IL76. The separation properties of SLB-IL76 are closest to the bis(polycyanopropyl)siloxane stationary phases with a high percentage of bis(cyanopropyl)siloxane monomer and could be used in method development when a stationary phase with similar gross retention characteristics but different selectivity is required.

Calcium ion is an important cation influencing the binding of recalcitrant organic contaminants with activated sludge during wastewater treatment process, but there is still unknown about its role in amphoteric fluoroquinolones binding. Binding experiments show that Ca2+ markedly inhibited binding of ciprofloxacin (CIP) onto sludge, causing 7-203 times of CIP release. Multi-spectroscopic examinations indicate that tryptophan-like and tyrosine-like proteins in extracellular polymeric substances (EPS) were dominant components for CIP binding by static quenching and forming CIP-proteins complexes. Addition of Ca2+ into EPS and CIP binding systems induced increase of association constants (from 0.024-0.064 to 0.027-0.084 L/mu mol) and binding constants (from 0.002-0.039 to 0.012-0.107) and decrease of binding sites number (from 0.893-2.007 to 0.721-1.386). Functional groups of EPS and secondary structure of proteins were remarkably changed upon reactions with CIP and Ca2+. Calcium ion interacted with EPS and CIP binding system in two distinct ways: Ca2+ shielded Cdouble bondO in amide I in EPS for CIP binding, whereas strengthened binding between CIP and functional groups including Cdouble bondO in carboxyl groups in extra-microcolony polymers and Osingle bondH in extra-cellular polymers by forming ternary complexes. Cation competition for Cdouble bondO in amide I is responsible for Ca2+ induced CIP release from the sludge. Results suggest the highly potential release of CIP from high saline wastewater and cation-conditioned sludge which needs further monitoring and evaluation. (C) 2020 Elsevier B.V.

The development of amino acid surfactants which are considered to be biodegradable and less toxic than traditional surfactants has been a subject of growing interests among chemists for the past 20 years. Within this category, N-acyl amino acid surfactants are popular due to their excellent interfacial properties and antimicrobial activities. In the present work, six new N-acyl amino acid surfactants were synthesized using vegetable oils (castor oil and cottonseed oil) and amino acids (glycine, alanine, and serine). Surface active properties of these surfactants were investigated. With the amide bonds acting as hydrogen bond donors and acceptors, globular and tubular vesicles were observed in the aqueous solutions of some prepared surfactants. The results indicated that hydroxyl groups on the hydrophobic tails for castor oil derivatives were associated with spherical vesicles formation, whereas serine residues bearing hydroxyl groups may be associated with the tubular vesicles.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 637-01-4, you can contact me at any time and look forward to more communication.

Multi-functional supramolecular fluorescent materials are an intriguing concern for materials science. Herein, an easily prepared bi-component hydrogel with strong aggregation-induced emission (ME) (MQ-G) was successfully constructed by the gelators naphthalimide derivative (M) and tri-(pyridine-4-yl)-functionalized trimesic amide (Q) in DMSO-H2O (6 : 4, v/v) via pi – pi, hydrogen bond and pi – electron donor-acceptor interactions. The obtained bi-component hydrogel MQ-G has an excellent self-healing property. Interestingly, the MQ-G exhibits strong orange AIE, the fluorescence quantum yield of the MQ-G was measured as 0.578. Moreover, the MQ-G could successively sense Fe3+ and H-2 PO4- in water through a fluorescent ON-OFF-ON pathway, which suggests the MQ-G could serve as an ON-OFF-ON fluorescent material and efficient logic gate. Meanwhile, the xerogel of MQ-G is capable of removing Fe3+ at an adsorption rate of 99.74% in diluted aqueous solution. Moreover, the thin films based on the MQ-G and MQ-G + Fe3+ were also prepared, which could not only act as supramolecular fluorescent material but a simple and efficient tool for detection Fe3+ and H2PO4-, respectively.
