Incomplete Refolding of Antibody Light Chains to Non-Native, Protease-Sensitive Conformations Leads to Aggregation: A Mechanism of Amyloidogenesis in Patients?

Genetic biochemical, and pharmacologic evidence supports the hypothesis that conformationally altered or misfolded protein states enable aggregation and cytotoxicity in the systemic amyloid diseases. Reversible structural fluctuations of natively folded proteins are involved in the aggregation of many degenerative disease associated proteins. Herein, we use antibody light chains (LCs) that form amyloid fibrils in AL amyloidosis to consider an alternative hypothesis of amyloido-geneis: that transient unfolding and incomplete extracellular refolding of secreted proteins can lead to metastable, alternatively folded states that are more susceptible to aggregation or to endoproteolysis that can release aggregation prone fragments. Refolding of full-length lambda 6a LC dimers comprising an interchain disulfide bond from heat- or chaotrope-denatured ensembles in :buffers yields the native dimeric state as well as alternatively folded dimers and aggregates. LC variants lacking an interchain disulfide bond appear to refold fully reversibly to the native state. The conformation of a backbone peptidyl-proline amide in the LC constant domain, which is cis in the native State, may determine whether the LC refolds back to the native state. A praline to alanine (P147A) LC variant, which cannot form the native cis, amide conformation, forms amyloid fibrils from the alternatively folded ensemble, whereas all the full-length lambda 6a LCs we have studied to date do not form amyloid under analogous conditions. P147A LC Variants are susceptible to endoproteolysis by thrombin, enabling amyloidogenesis of the fragments released. Thus, non-native LC structural ensembles containing a tyrosine 146-proline 147. trans-amide bond can initiate and propagate amyloid formation, either directly or after aberrant endoproteolysis.

Oxidation of Thioamides to Amides with Tetrachloro- and Tetrabromoglycolurils

Tetrabromo- and tetrachloroglycolurils have been shown to act as good oxidants capable of converting thioamides to the corresponding amides. This approach offers such advantages as good yields (81-99%), short reaction times (10-25 min), simple workup procedure, and environmental safety.

Synthesis of Vicinal Bromoamine Compounds via Three Components Reaction of beta,beta-Dicyanostyrene/Amide/N-Bromo-succinimide

Vicinal bromoamine derivative belongs to an important class of difunctionalization compounds. New synthetic method and new vicinal bromoamine derivatives are eagerly desired. Thus, a new one-pot protocol for the synthesis of vicinal bromoamines from beta, beta-dicyanostyrene derivatives/amides/N-bromo-succinimide was developed. In the presence of anhydrous K2CO3, beta, beta-dicyanostyrenes reacted smoothly with amides and N-bromo-succinimide (NBS) to generate the vicinal bromoamine compounds in good to excellent yield (up to 93% yield) at room temperature without the protection of inert gas in CH2Cl2. 13 different structural beta, beta-dicyanostyrene derivatives reacted with 7 different structural amides (acrylamide, acetamide, valeramide, isobutyramide, benzamide, 4-nitrobenzamide, ethylurethanm) and NBS have been investigated in this work. The results indicated that the method is not only widely subjected to beta, beta-dicyanostyrene, but also suitable for the different type of amide. The structures of all the products were confirmed by their nuclear magnetic resonance spectroscopy (NMR), infrared spectra (IR) and high resolution mass spectrometry (HRMS), and the possible reaction mechanism was proposed.

Antiepileptic and Neuroprotective Effects of Oleamide in Rat Striatum on Kainate-Induced Behavioral Seizure and Excitotoxic Damage via Calpain Inhibition

Oleamide was first known as a sleep-inducing fatty acid amide, and later shown to have wide range of neuropharmacological effects upon different neurochemical systems. However, the effects of oleamide on brain damage have scarcely been studied, and the molecular mechanisms and sites of its action remain elusive. Kainic acid (KA) has been used to produce an epileptic animal model that mimics human temporal lobe epilepsy and to induce calpain-activated excitotoxicity, which occurs in numerous neurodegenerative disorders. In this study, we examined whether oleamide protects against the KA-induced excitotoxic brain damage accompanied by behavioral seizure activity and neuronal cell death. Moreover, whether these effects of oleamide were mediated by calpain activity-related cellular mechanisms was investigated. KA-induced epileptic rats were produced by an intrastriatal injection of KA (5 nmole). Oral administration of oleamide (0.5, 2, and 10 mg/kg) 30 min prior to the KA injection showed dose-dependent inhibition of the KA-induced behavioral seizure activities that were monitored starting from 60 to 180 min post-surgery. Further repetitive oral administration of oleamide (once per day) for the next 4 consecutive days post-KA injection produced significant neuroprotection against the disrupted neuronal integrity that resulted from KA-induced excitotoxic damage that was also demonstrated by staining of striatal tissue sections with cresyl violet, hematoxylin/eosin, and fluoro-Jade B. In addition, oleamide blocked the KA-induced cleavage of cyclin-dependent kinase-5 coactivator (Cdk5-p35) and collapsin response mediator protein-2, which are believed to be mediated by calpain activation in striatal tissues dissected from KA-induced epileptic rats. Oleamide also reversed the KA-induced reduction in expression of an endogenous calpain inhibitory protein, calpastatin, and a marker of synaptic activity, synapsin-II. The hypothesis that oleamide could induce direct calpain inhibition was further investigated using in vitro calpain assays in both brain tissue and a cell-free and calpain-overexpressed neuronal cell system. These findings together suggest that oleamide has protective effects against excitotoxicity-induced neuronal death and behavioral seizure, partly via its direct calpain inhibitory activity.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 27532-96-3, you can contact me at any time and look forward to more communication. HPLC of Formula: C6H14ClNO2.

Intermolecular interactions in the crystal structures of chlorogold(I) complexes with N-phosphinoamide ligands

[AuCl{RC(O)NHPPh2-kappa P}]gold(I) complexes with varying amide substituents (R = Me, Ph and ferrocenyl) were prepared, characterized by elemental analysis and spectroscopic methods (mass spectrometry and multinuclear NMR and IR spectroscopy) and further studied by single-crystal X-ray crystallography with a particular focus on solid-state interactions. In all cases, the crystal assembly was based mainly on conventional hydrogen bonds between the amide moieties. However, while in chloroform-solvated [AuCl{MeC(O)NHPPh2-kappa P}], these interactions were supported by pi center dot center dot center dot pi stacking of aromatic rings, in the crystal structures of the complexes bearing phenyl and ferrocenyl substituents, they cooperated with aurophilic interactions of the Au(I) centers, which in turn affected the C = O center dot center dot center dot HN hydrogen bonds.

Functionalized SERS substrate based on silicon nanowires for rapid detection of prostate specific antigen

Owing to its high sensitivity, surface-enhanced Raman spectroscopy (SERS) is widely used in biosensing as an efficient optical transduction technique. In this work, we report the elaboration of a novel SERS-powered aptasensing substrate for the ultra-sensitive and selective detection of prostate specific antigen (PSA). The transducing SERS substrate is formed by vertically aligned silicon nanowires (SiNWs) decorated with silver nanoparticules (AgNPs). The silver nanoparticles have two purposes : a) aptamer immobilization via thiol chemistry and b) Raman signal enhancement. The presence of PSA induces the appearance of amide bond vibration modes only if the aptamer is present on the surface of SiNWs. The platform is highly sensitive, selective and specific to PSA in a wide range of concentrations from 0.1 to 20 mu g.L-1 with a detection limit of 0.1 mu g.L-1, which encompasses the blood serum range of healthy subjects and ill patients. This optical biosensor shows a great stability and it is successfully validated in human blood serum samples showing very good results.

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 38256-93-8 is helpful to your research. Safety of 2-Methoxy-N-methylethanamine.

Impact of gamma-ray irradiation on some aryl-amide-bridged Schiff-base complexes: spectral, TGA, XRD, and antioxidant properties

Some aryl amide Schiff base Co(II), Ni(II) and Cu(II) distance between Cu(II) and complexes (1-7) have been obtained and identified by various analytical and spectroscopic tools. To through a light on the probability of structure changes with gamma-irradiation, powder samples of complexes 1, 3, 5 and 6 were irradiated with Co-60 gamma-rays at dose of 100 kGy (hereafter referred to as 1F, 3F, 5F and 6F). Spectral, molar conductance, magnetic susceptibility, thermal, X-ray diffraction and antioxidant activity for the irradiated complexes were gained using similar methods used for the non-irradiated complexes. The data revealed that the irradiated complexes were not seriously affected by the utilized gamma-irradiation dose.

Iron-Catalyzed Directed Alkylation of Carboxamides with Olefins via a Carbometalation Pathway

A catalytic amount of an iron salt and bipyridine ligand in the presence of an organozinc base activates the ortho C-H bond of a carboxamide, and the following reaction with an alkene such as ethylene gas (1 atm), styrene derivatives, and vinylsilane or vinylboron derivatives via carbometalation gives a putative alkylzinc intermediate. This intermediate can be further reacted with electrophiles such as deuterium oxide or allyl bromide. When monosubstituted alkenes are used as a substrate, the linear alkyl product is selectively obtained. The monoalkylated product is exclusively obtained, and dialkylation does not proceed.
