Heterocyclic scaffolds for the treatment of Alzheimer?s disease

Background: The treatment and diagnosis of Alzheimer?s Disease (AD) are two of the most urgent goals for research around the world. The cognitive decline is generally associated with the elevated levels of extracellular senile plaques, intracellular neurofibrillary tangles (NFTs), and with a progressive shutdown of the cholinergic basal forebrain neurons transmission. Even if several key targets are under fervent investigation in the cure of AD, till now, the only approved therapeutic strategy is the treatment of symptoms by using cholinesterases inhibitors. It has been demonstrated that both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) enzymes are not only responsible of acetylcholine levels, but also play an pivotal role in A[1]-aggregation during the early stages of senile plaque formation. On the other hand the difficult management of AD is also related to effective diagnostic methods and efficient assays for the study of pathological features. In such complex a wide framework, heterocyclic molecules are essential backbone to build new and selective drugs as well as diagnostic probes. Methods: The goal of this review is to examine a selected sample of relevant applications of five- and six-membered heterocycles in AD’s therapeutic approaches. Results: Concerning the research on AD, the contribution of heterocyclic compounds is huge and here we report some representative examples. The review is organized in two main sections focused on five and six-membered heterocycles. The analyzed cases have been classified on the base of the structural features of molecules, taking into account the progressive increase in heteroatoms number. Conclusion: The discovery of an effective therapy or a diagnostic protocol for AD is still far, but consistent improvements are underway and contribution of heterocyclic compounds will be consistent and hopefully determinant.

Photophysical and Photoprototropic Characteristics of 2-Aminobenzothiazole in beta-Cyclodextrin Medium

The formation of stable inclusion complexes between neutral and monocationic species of 2-aminobenzothiazole (2ABT) with beta-CDx is observed with significant enhancement in absorbance and fluorescence intensity. The stoichiometry of the 2ABT and 2ABTH? with beta-CDx is found to be 1:1 at pH?6.8 and 1.1. Their binding constant values for neutral and monocationic species are found to be 1239.3 and 1259.2?M?1, respectively. Lifetime analysis, FT-IR spectral and SEM image analysis strongly supports the formation of the inclusion complex between 2ABT and beta-CDx. Photoprototropic study shows that there is no remarkable difference in the pKa and pKa* in aqueous and beta-CDx media, which is rules out the formation of the inclusion complex with ?NH2 group of 2ABT inside the cavity of beta-CDx i.e., the ?NH2 group of 2ABT is in aqueous environment. Based on stoichiometry, binding constant and acidity constant values, the structure of the 1:1 complex is proposed.

Effect of fragmentation degree on sensory and texture attributes of cooked rice

This study investigated the possibility of classified utilization of broken rice by analyzing sensory and texture attributes of cooked rice with different fragmentations. Compared with head rice, the relative concentration of volatile components in broken rice with three fragmentations (25%, 50%, 75%) increased 21%, 43% and 26%, respectively. Among them, 50% fragmentation rice sample contained the greatest amount of typical rice related aroma compounds, including heptanal, hexanal, nonanal, 1-octen-3-ol, 1-pentanol and 2-pentylfuran. Moreover, 50% fragmentation could increase the taste intensity of fruitiness, nuttiness, toastiness and sweetness of cooked rice significantly. The hardness of cooked rice was found to be negatively related with fragmentation degree, while the stickiness and water soluble protein content were positively related with fragmentations. The results of this study suggest that suitable utilization of broken rice with 50% fragmentation has a potential to enhance desirable rice flavor and increase staple food supply. Practical applications: During rice processing, broken rice with different fragmentations will form inevitably, the composition of which is not different from head rice, but much cheaper. Broken rice with 50% fragmentation has a potential to add desirable rice flavor to cooked rice. Thus suitable utilization of broken rice could be applied to achieve high added-value of rice milling by-product.

A self-attention based message passing neural network for predicting molecular lipophilicity and aqueous solubility

Efficient and accurate prediction of molecular properties, such as lipophilicity and solubility, is highly desirable for rational compound design in chemical and pharmaceutical industries. To this end, we build and apply a graph-neural-network framework called self-attention-based message-passing neural network (SAMPN) to study the relationship between chemical properties and structures in an interpretable way. The main advantages of SAMPN are that it directly uses chemical graphs and breaks the black-box mold of many machine/deep learning methods. Specifically, its attention mechanism indicates the degree to which each atom of the molecule contributes to the property of interest, and these results are easily visualized. Further, SAMPN outperforms random forests and the deep learning framework MPN from Deepchem. In addition, another formulation of SAMPN (Multi-SAMPN) can simultaneously predict multiple chemical properties with higher accuracy and efficiency than other models that predict one specific chemical property. Moreover, SAMPN can generate chemically visible and interpretable results, which can help researchers discover new pharmaceuticals and materials. The source code of the SAMPN prediction pipeline is freely available at Github (https://github.com/tbwxmu/SAMPN).

Innovative therapeutic potential of cannabinoid receptors as targets in alzheimer?s disease and less well-known diseases

The discovery of cannabinoid receptors at the beginning of the 1990s, CB1 cloned in 1990 and CB2 cloned in 1993, and the availability of selective and potent cannabimimetics could only be justified by the existence of endogenous ligands that are capable of binding to them. Thus, the characterisation and cloning of the first cannabinoid receptor (CB1) led to the isolation and characterisation of the first endocannabinoid, arachidonoylethanolamide (AEA), two years later and the subsequent identification of a family of lipid transmitters known as the fatty acid ester 2-arachidonoylglycerol (2-AG). The endogenous cannabinoid system is a complex signalling system that comprises transmembrane endocannabinoid receptors, their endogenous ligands (the endocannabinoids), the specific uptake mechanisms and the enzymatic systems related to their biosynthesis and degradation. The endocannabinoid system has been implicated in a wide diversity of biological processes, in both the central and peripheral nervous systems, including memory, learning, neuronal development,32 stress and emotions, food intake, energy regulation, peripheral metabolism, and the regulation of hormonal balance through the endocrine system. In this context, this article will review the current knowledge of the therapeutic potential of cannabinoid receptor as a target in Alzheimer?s disease and other less well-known diseases that include, among others, multiple sclerosis, bone metabolism, and Fragile X syndrome. The therapeutic applications will be addressed through the study of cannabinoid agonists acting as single drugs and multi-target drugs highlighting the CB2 receptor agonist. 32.

Recent progress in the discovery and development of DNA gyrase B inhibitors

New antibacterials that modulate less explored targets are needed to fight the emerging bacterial resistance. DNA gyrase and topoisomerase IV are attractive targets in this search. These are both type II topoisomerases that can cleave both DNA strands, and can thus alter DNA topology during replication or similar processes. Currently, there are no ATP-competitive inhibitors of these two enzymes on the market, as the only aminocoumarin representative, novobiocin, was withdrawn due to safety concerns. The search for novel ATP-competitive inhibitors is a focus of ongoing industrial and academical research. This review summarizes the recent efforts in the design, synthesis and evaluation of GyrB/ParE inhibitors. The various approaches to achieve improved antibacterial activities are described, with particular reference to Gram-negative bacteria.

Thermal degradation of keratin waste

Thermal degradation of sheep wool, human hair and chicken feathers was studied by TG-MSD/FTIR and by pyrolysis followed by GC-MSD analysis in order to identify the degradation compounds and the temperature range in which they are formed. Only small differences were found between the studied keratin samples. They consist mainly in shift of characteristic temperatures of degradation and in relative amounts of compounds in degradation products, especially in aqueous phase. Degradation started with formation of ammonia and CO2 (from 167 and 197 C respectively and with maximum evolution at 273 and 287 C respectively), continues with formation of sulphur-containing inorganic compounds (SCS, SCO, H2S and SO2 at 240, 248, 255 and 253-260 C respectively) and of water (255 C). Thiols are formed in two stages (257 and 320 C) while the evolution of nitriles is maximum around 340 C and continues up to about 480 C. Phenol and 4-methylphenol are the most important degradation compounds, formed at 370 and 400 C respectively. Nitrogen was present mainly in aliphatic/aromatic nitriles, pyrroles, pyridines and amides while sulphur was found mainly as sulphides, thiols, thiazoles and thiophenes.

Volatile compounds of past?rma under different curing processes

The effects of different curing processes (curing temperature 4C or 10C and curing agent 150?mg/kg nitrite or 300?mg/kg nitrate) on the volatile compound profile of the past?rma (Turkish dry-cured meat product) have been investigated. A total of 45 volatile compounds, including alcohols, aldehydes, ketones, aliphatic and aromatic hydrocarbons, terpenes, sulphur compounds, esters, furans and nitrogenous compounds have been identified in past?rma samples. The curing temperature did not have a significant effect on any compound. The curing agent had statistically a significant or very significant influence on 12 compounds. In general, the use of nitrate increased the amount of volatile compound. However, lower mean hexanal value was determined in past?rma samples cured with nitrite than those cured with nitrate. Practical applications: Past?rma is a traditional dry-cured meat product. It is produced from whole muscle and/or mucsles of certain parts of beef or water buffalo carcasses. In curing stage, nitrate was used generally. However, nitrite can be used alone or with nitrate in this stage. In this study, the effects of different curing conditions (150?mg/kg nitrite or 300?mg/kg nitrate and 4C or 10C) on volatile compounds of past?rma were investigated. According to the results, past?rma produced with nitrate generally showed higher amounts of volatile compounds. On the other hand, curing temperature was not significant factor in terms of volatile compounds.

Pseudosaccharin amine derivatives: Synthesis and elastase inhibitory activity

Pseudosaccharin amines were synthesized from saccharin either by the reaction of pseudosaccharin chloride with amines, or via thiosaccharin which was treated with amines yielding thiosaccharinates, and their reaction with glacial acetic acid. This route gave lower yields than the first way. The synthesis of alkyl [(1,1-dioxo-benzo[d]isothiazol-3-yl)amino]alkanoates as possible Human Leukocyte Elastase (HLE) inhibitors was realized by the reaction between amino acid esters and pseudosaccharin chloride. Hydrolysis of the esters was possible under aqueous basic conditions. Selected compounds were screened for elastase inhibitory activity. Compounds 4k and 4m were found to be reversible inhibitors of HLE with Ki values of 45 muM and 60 muM.
