This work examines howN-donor bridged spacer ligands affectN-heterocyclic carbene (NHC) palladium complexes catalytic activities for Suzuki coupling reaction. Different degrees of structural flexibility binuclear NHC palladium complexes were synthesized. The more flexible nitrogen-based alkyl chain ligand shows similar performance with cycloamine counterparts in the Suzuki coupling reaction. Suzuki coupling examples were used in air and ambient temperature to reach moderate to completion yields in short time. Density functional theory calculations showed that the chelate effect, associated with a single Pd complex mechanism, plays a fundamental role in the pre-catalysis stage, supporting a reasonable of the kinetic activity observed experimentally.

Most microplastics (MPs) have undergone extensive aging in the environment. Aged MPs exhibit different physical and chemical properties from unaged ones. Here, we studied the effects of accelerated aging on the characteristics and pyrolysis of commercial pigmented MPs, as well as pigments leaching and their interactions in simulated gastric and intestinal fluids of mammals. We report that the carbonyl index, surface area, and color change of MPs increased after aging treatment. Cracks and fragmentation of MPs facilitated the accessibility of light and oxygen to internal layer and therefore accelerated the aging process. TGA/GC-MS analysis showed that the high temperature resistance of MN decreased after aging. Thermal decomposition of pigments and polyethylene occurred in temperature ranges of 340-406 degrees C and 406-550 degrees C, respectively. Mono (di)-alkenes and saturated alkanes were the thermal decomposition products of polyethylene. Aging of MPs also caused an increased release of pigments and prolonged aging time led to more release in simulated fluids. Pigments would result in fluorescence quenching of the enzymes through binding interactions once they were released from MPs into simulated fluids. Charge neutralization and polymer bridging accounted for the formation of pigment-enzyme complexes and flocs. These novel findings will allow us to better assess how aging process affects the characteristics, leaching, and toxicity of MPs. (C) 2020 Published by Elsevier B.V.

beta-Glucuronidase is responsible for the catalytic deconjugation of beta-D-glucuronides. beta-Glucuronidase has evolved to be a viable molecular target for numerous therapeutic treatments. It plays a pivotal role in the metabolism of drugs and endogenous substances. Herein, we report the inhibitory potentials of newly developed and modular benzimidazole-triazolothiadiazole hybrids spaced through a phenyl linker (1-26) and their interactions with the beta-glucuronidase. All analogues showed IC50 values in the range of 1.30 +/- 0.10 to 44.10 +/- 0.80 mu M, and hence were found to have outstanding inhibitory potential as compare to the standard D-saccharic acid 1,4-lactone (IC50 = 48.4 +/- 1.25 mu M). These modular hybrids were successfully synthesized, rigorously characterized through various spectroscopic techniques. Molecular docking studies further revealed the potential interactions between the inhibitor and active amino acid site in beta-glucuronidase. These findings helped in identifying the potential for new drug candidates. A Plausible structure activity relationship (SAR) were established which suggested that variation in the inhibitory potential was mainly based upon the substituents attached to the phenyl ring.

Multitargeted hybrids of N-benzylpiperidine and substituted 5-phenyl-1,3,4-oxadiazoles were designed, synthesized, and evaluated against Alzheimer’s disease (AD). Tested compounds exhibited moderate to excellent inhibition against human acetylcholinesterase (hAChE), butyrylcholinesterase (hBChE), and beta-secretase-1 (hBACE-1). The potential leads 6g and 10f exhibited balanced inhibitory profiles against all the targets, with a substantial displacement of propidium iodide from the peripheral anionic site of hAChE. Hybrids 6g and 10f also elicited favorable permeation across the blood -brain barrier and were devoid of neurotoxic liability toward SH-SYSY neuroblastoma cells. Both leads remarkably disassembled A beta aggregation in thioflavin T-based selfand AChE-induced experiments. Compounds 6g and 10f ameliorated scopolamine gamma-induced cognitive dysfunctions in the Ymaze test. The ex vivo studies of rat brain homogenates established the reduced AChE levels and antioxidant activity of both compounds. Compound 6g also elicited noteworthy improvement in A beta-induced cognitive dysfunctions in the Morris water maze test with downregulation in the expression of A beta and BACE-1 proteins corroborated by Western blot and immunohistochemical analysis. The pharmacokinetic study showed excellent oral absorption characteristics of compound 6g. The in silica molecular docking and dynamics simulation studies of lead compounds affirmed their consensual binding interactions with PAS-AChE and aspartate dyad of BACE-1.

Faramarzi, Z; Abbasitabar, F; Zare-Shahabadi, V; Jahromi, HJ in [Faramarzi, Zohreh; Zare-Shahabadi, Vahid; Jahromi, Hossein Jalali] Islamic Azad Univ, Dept Chem, Mahshahr Branch, Mahshahr, Iran; [Abbasitabar, Fatemeh] Islamic Azad Univ, Dept Chem, Marvdasht Branch, Marvdasht, Iran published Novel mixture descriptors for the development of quantitative structure-property relationship models for the boiling points of binary azeotropic mixtures in 2019.0, Cited 38.0.

Binary azeotropes, which contain two chemical constituents, are very common in industry. Understanding azeotropic properties is crucial for effectively separating binary azeotropes. Experimental and theoretical approaches such as ab initio have been used to estimate mixture properties but they are costly and time-consuming. The quantitative structure-property relationship (QSPR) model is a viable alternative approach. The most challenging problem in the QSPR study of mixtures is the computation of numerical descriptors to characterize a mixture. In this study, a series of twenty-two formulas were proposed to derive mixture descriptors from the molecular descriptors of the individual pure compounds. The derived mixture descriptors were employed to establish QSPR models to predict the boiling point of binary azeotropic mixtures. The QSPR model developed was found to be the best with R-train(ing)2 and R-test(2) of 0.92 and 0.90 on the basis of a novel proposed formula, in which some coefficients related to the potential energy contribution were used. Mean absolute errors (MAEs) associated with training and test sets were computed as 9.90 and 10.61, respectively. Twelve out of the twenty-two mixture descriptors resulted in the QSPR models with reasonable statistical qualities and, therefore, were taken into account in the production of an ensemble model via a simple averaging strategy. This caused to improve statistical quality of the final QSPR model. (C) 2019 Published by Elsevier B.V.

Tropomyosin receptor kinases (TrkA, TrkB, TrkC) are activated by hormones of the neurotrophin family: nerve growth factor (NGF), brain derived neurotrophic factor (BDNF), neurotrophin 3 (NT3), and neurotrophin 4 (NT4). Moreover, the NGF antibody tanezumab has provided clinical proof of concept for inhibition of the TrkA kinase pathway in pain leading to significant interest in the development of small molecule inhibitors of TrkA. However, achieving TrkA subtype selectivity over TrkB and TrkC via a Type I and Type II inhibitor binding mode has proven challenging and Type III or Type IV allosteric inhibitors may present a more promising selectivity design approach. Furthermore, TrkA inhibitors with minimal brain availability are required to deliver an appropriate safety profile. Herein, we describe the discovery of a highly potent, subtype selective, peripherally restricted, efficacious, and well-tolerated series of allosteric TrkA inhibitors that culminated in the delivery of candidate quality compound 23.

A family of 2-(9H-carbazol-9-yl)phenyl-based phosphine ligands were synthesized and their efficacy in promoting the steric hindered Buchwald-Hartwig amination was evaluated. In the presence of Pd(OAc) (2) (0.03-1.0 mol%) associated with the newly developed a carbazolyl-derived phosphine ligand, the synthesis of tetra- ortho -substituted diarylamines proceeded smoothly with excellent product yields (up to 99%). A remarkable result was obtained even for the coupling of highly sterically congested 2,6-diisopropylaniline and hindered 2-chloro-1,3,5-triisopropylbenzene (96% isolated yield). A possible decomposition pathway for the anthracenyl C-N coupling product is also reported.

The A-type Aurora kinase is upregulated in many human cancers, and it stabilizes MYC-family oncoproteins, which have long been considered an undruggable target. Here, we describe the design and synthesis of a series of pyrimidine-based derivatives able to inhibit Aurora A kinase activity and reduce levels of cMYC and MYCN. Through structure-based drug design of a small molecule that induces the DFG-out conformation of Aurora A kinase, lead compound 13 was identified, which potently (IC50 < 200 nM) inhibited the proliferation of high-MYC expressing small-cell lung cancer (SCLC) cell lines. Pharmacokinetic optimization of 13 by prodrug strategies resulted in orally bioavailable 25, which demonstrated an 8-fold higher oral AUC (F = 62.3%). Pharmacodynamic studies of 25 showed it to effectively reduce cMYC protein levels, leading to >80% tumor regression of NCI-H446 SCLC xenograft tumors in mice. These results support the potential of 25 for the treatment of MYC-amplified cancers including SCLC.
