In the present research article, a hyperbranched alkyd resin was synthesized by using bio-based material (castor oil based fatty amide) and pyromellitic dianhydride. The synthesized hyperbranched alkyd resin was characterized by nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) spectroscopy. The polyurethanes (PMFAI and PMFAM) were prepared from hyperbranched alkyd resin and diisocyanates [isophorone diisocyanates (IPDI) and methylene diphenyl diisocyanate (MDI)] maintaining the OH:NCO ratio of 1:1.2. These polyurethanes were used in coating applications on mild steel and wood panels. The performance of cured polyurethane coatings was studied in terms of crosscut adhesion, impact resistance, gloss, scratch hardness, and chemical resistance. The chemical resistance test was performed by immersion method in 2 N HCl, 2 N NaOH, 3.5% NaCl solution, xylene, and water. The corrosion rate and anticorrosion efficiency of the coating panels were determined by a potentiostat. From a study of coating properties, it was found that the PMFAI and PMFAM exhibited better coating properties as compared to reported linear alkyd polyurethanes. The stain test of coatings was performed on wood panels. The thermal behavior of the coatings was determined by thermogravimetric analyzer. The surface morphology of coating films was examined by scanning electron microscopy and atomic force microscopy. It was found that the coating properties of hyperbranched alkyd resin were excellent as compared to linear alkyd resin polyurethanes.

In the present report, we describe the synthesis of the amide derivative, N-(2,4-dichlorophenyl)-1-naphthamide, 3, via a facile chemical route. The title compound was isolated in 86% yield. The structure of compound 3 was established using spectroscopic methods and X-ray crystallography. In the crystal structure of 3, supramolecular assembly is dominated by classical N-H center dot center dot center dot O hydrogen bonding and C-Cl center dot center dot center dot pi halogen bonding interactions which were examined in detail using several theoretical methods and DFT calculations. The optimized geometric parameters of compound 3 were calculated using density functional theory (DFT/B3LYP and DFT/M06-2X) quantum chemical methods with the 6-311++G(d,p) basis set using the crystallographic coordinates. Additionally, fragments contributing to the HOMO and LUMO molecular orbitals were investigated at the same level of theory. The nature and various types of intermolecular interactions in the crystal structure were also realized by Hirshfeld surface analysis. The biological properties such as anti-Alzheimer’s potential were also assessed which reveals strong acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory effects. Compound 3 was 16-fold more active inhibitor of acetylcholinesterase compared to neostigmine with an IC50 value of 1.044 +/- 0.76 mu M in addition to 21-fold strong inhibition against butyrylcholinesterase. The in vitro bioactivity results were further strengthened by the molecular docking analysis revealing the presence of several important interactions with the active site residues from cholinesterase (AChE & BChE) enzymes.

Two efficient procedures have been developed for the synthesis of pyroglutamic acid analogues 28, 29, and 34. According to the first method the Ugi (4C3C) reaction is followed by a post-transformation reaction, and the second method involves the Michael addition reaction. The present methodologies demonstrate the applicability of 1-(2,2-dimethoxyethyl)-2-isocyanobenzene (15) as a cleavable isocyanide in the Ugi/ post-transformation reaction and a strong nucleophile in the Michael addition reaction. The framework of pyroglutamic acid analogues has been constructed by the selective cleavage of the C-terminal amide bond and nucleophilic addition to the activated alpha,beta-unsaturated carbonyl group.

The design, synthesis, and biological evaluation of stilbene-based novobiocin analogues is reported. Replacement of the biaryl amide side chain with a triazole side chain produced compounds that exhibited good antiproliferative activities. Heat shock protein 90 (Hsp90) inhibition was observed when N-methylpiperidine was replaced with acyclic tertiary amines on the stilbene analogues that also contain a triazole-derived side chain. These studies revealed that approximate to 24 angstrom is the optimal length for compounds that exhibit good antiproliferative activity as a result of Hsp90 inhibition.

Exogenous antioxidants may be beneficial therapeutic tools to tackle the oxidative damage in neurodegenerative diseases by regulation of the redox state that is critical for cell viability and organ function. Inspired by natural plant polyphenols, a series of cinnamic acid-based thiophenolic and phenolic compounds were synthesized and their antioxidant and neuroprotective properties were studied. In general, our results showed that the replacement of the hydroxyl group (OH) by a sulfhydryl group (SH) increased the radical scavenging activity and enhanced the reaction rate with 1,1-diphenyl-2-picrylhydrazyl radical (DPPH center dot) and galvinoxyl radical (GO(center dot)). These results correlated well with the lower oxidation potential (E-p) values of thiophenols. However, a lower peroxyl radical (ROO center dot) scavenging activity was observed for thiophenols in oxygen radical absorbance capacity (ORAC-FL) assay. Furthermore, the introduction of 5-methoxy and 5-phenyl groups in the aromatic ring of 4-thioferulic acid (TFA) 2 and ferulic acid (FA) 1 did not significantly improve their antioxidant activity, despite the slight decrease of E-p observed for compounds 5, 6, and 9. Concerning cinnamic acid amides, the antioxidant profile was similar to the parent compounds. None of the compounds under study presented significant cytotoxic effects in human differentiated neuroblastoma cells. Thiophenolic amide 3 stands out as the most promising thiophenol-based antioxidant, showing cellular neuroprotective effects against oxidative stress inducers (hydrogen peroxide and iron).

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 52-89-1, Name is H-Cys-OH.HCl, molecular formula is C3H8ClNO2S.

The reactivity of cyclic tertiary sulfamidates derived from alpha-methylisoserine strongly depends on the substitution at the C and N termini. These substrates are one of the very few examples able to undergo nucleophilic ring opening at a quaternary carbon with complete inversion of the configuration, as demonstrated both experimentally and computationally. When the sulfonamide is unprotected, the characteristic ring-opening reaction is completely silenced, which explains that the majority of the ring-opening reactions reported in the literature invoke N alkyl or N-carbonyl-protected sulfamidates. Accumulation of negative charge at the NSO3 moiety in the transition state, especially when the sulfonamide NH is deprotonated, drastically raises the activation barrier for the nucleophilic attack. On the other hand, ester groups at the carboxylic position favor ring opening, whereas amides allow competition between the substitution and elimination pathways. Using pyridine as a nucleophilic probe, we have demonstrated both experimentally and computationally that a proper selection of the substitution scheme can enhance the synthetic scope of alpha-methylisoserine-derived sulfamidates, switching off and on the nucleophilic ring-opening in a controlled manner. This is particularly convenient for hybrid alpha/beta-peptide synthesis, as demonstrated recently by our group.

The Cu(II) and Zn(II) binding abilities of Gly-His-Thr-Asp-amide (GHTD-am), a tetrapeptide coreleased from the pancreas along with insulin, were studied using UV-vis and circular dichroism spectroscopies, potentiometry, and calorimetry. GHTD-am is a very strong Cu(II) chelator, forming a three-nitrogen complex with a conditional affinity constant K-c at pH 7.4 of 4.5 X 10(12) M-1. The fourth coordination site can be occupied by a solvent molecule or a ternary ligand, such as imidazole, with K-c on the order of several hundred reciprocal molar. The Zn(II) binding ability of GHTD-am is relatively weak, with K-c values at pH 7.4 of 3.0 X 10(4) and 2.0 x 10(3) for the first and second GHTD-am molecule coordinated, respectively. These results are discussed in light of the modes of interactions of Zn(II) and Cu(II) ions with insulin. A direct effect of GHTD-am on the Zn(II) interactions with insulin is unlikely, but its Cu(II) complex may have a biological relevance because of its high affinity and ability to form ternary complexes.

Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 333-93-7, Name is 1,4-Diaminobutane dihydrochloride, molecular formula is C4H14Cl2N2.

Polyunsaturated fatty acids (PUFAs) are lipid derivatives of omega-3 (docosahexaenoic acid, DHA, and eicosapentaenoic acid, EPA) or of omega-6 (arachidonic acid, ARA) synthesized from membrane phospholipids and used as a precursor for endocannabinoids (ECs). They mediate significant effects in the fine-tune adjustment of body homeostasis. Phyto- and synthetic cannabinoids also rule the daily life of billions worldwide, as they are involved in obesity, depression and drug addiction. Consequently, there is growing interest to reveal novel active compounds in this field. Cloning of cannabinoid receptors in the 90s and the identification of the endogenous mediators arachidonylethanolamide (anandamide, AEA) and 2-arachidonyglycerol (2-AG), led to the characterization of the endocannabinoid system (ECS), together with their metabolizing enzymes and membrane transporters. Today, the ECS is known to be involved in diverse functions such as appetite control, food intake, energy balance, neuroprotection, neurodegenerative diseases, stroke, mood disorders, emesis, modulation of pain, inflammatory responses, as well as in cancer therapy. Western diet as well as restriction of micronutrients and fatty acids, such as DHA, could be related to altered production of pro-inflammatory mediators (e.g. eicosanoids) and ECs, contributing to the progression of cardiovascular diseases, diabetes, obesity, depression or impairing conditions, such as Alzheimer’ s disease. Here we review how diets based in PUFAs might be linked to ECS and to the maintenance of central and peripheral metabolism, brain plasticity, memory and learning, blood flow, and genesis of neural cells.
