Predicting the acute toxicity of a large dataset of diverse chemicals against fathead minnows (Pimephales promelas) is challenging. In this paper, 963 organic compounds with acute toxicity towards fathead minnows were split into a training set (482 compounds) and a test set (481 compounds) with an approximate ratio of 1 : 1. Only six molecular descriptors were used to establish the quantitative structure-activity/toxicity relationship (QSAR/QSTR) model for 96 hourpLC(50)through a support vector machine (SVM) along with genetic algorithm. The optimal SVM model (R-2= 0.756) was verified using both internal (leave-one-out cross-validation) and external validations. The validation results (q(int)(2)= 0.699 andq(ext)(2)= 0.744) were satisfactory in predicting acute toxicity in fathead minnows compared with other models reported in the literature, although our SVM model has only six molecular descriptors and a large data set for the test set consisting of 481 compounds.

An article Complete biodegradation of azo dye in an integrated microbial fuel cell-aerobic system using novel bacterial consortium WOS:000457290400039 published article about BIOELECTRICITY GENERATION; WASTE-WATER; DECOLORIZATION in [Das, A.; Mishra, S.] Natl Inst Technol, Dept Chem Engn, Biochem Engn Lab, Rourkela 769008, India in 2019.0, Cited 31.0. Formula: C8H8O2. The Name is 3-Methylbenzoic acid. Through research, I have a further understanding and discovery of 99-04-7

In the present work, a commercially used azo dye Remazol navy blue was completely degraded into less toxic intermediates in an integrated microbial fuel cell-aerobic system. A novel defined bacterial consortium comprising of organisms isolated from dye contaminated wastewater has been used as inoculum for this study. As compared to the traditional static incubation method, a rapid decolorization of Remazol navy blue was noticed in the anodic chamber of microbial fuel cell. In low to moderate dye concentrations (25-100mg/L), almost complete decolorization of Remazol navy blue was achieved within 12h of microbial fuel cell operation. The first-order kinetic constant of Remazol navy blue decolorization (k) in microbial fuel cell was found to be considerably higher than that of static incubation condition (K-static (0.3041)Formula: C8H8O2.

A molecular crystal of a 2-D hydrogen-bonded organic framework (HOF) undergoes an unusual structural transformation after solvent removal from the crystal pores during activation. The conformationally flexible host molecule, ABTPA, adapts its molecular conformation during activation to initiate a framework expansion. The microcrystalline activated phase was characterized by three-dimensional electron diffraction (3D ED), which revealed that ABTPA uses out-of-plane anthracene units as adaptive structural anchors. These units change orientation to generate an expanded, lower density framework material in the activated structure. The porous HOF, ABTPA-2, has robust dynamic porosity (SA(BET) = 1 183 m(2) g(-1)) and exhibits negative area thermal expansion. We use crystal structure prediction (CSP) to understand the underlying energetics behind the structural transformation and discuss the challenges facing CSP for such flexible molecules.

A concise and divergent approach for the total syntheses of four cembrane diterpenoids, namely (+)-sarcophytin, (+)-chatancin, (-)-3-oxochatancin, and (-)-pavidolideB, has been developed, and it also led to the structural revision of (-)-isosarcophytin. The key steps of the strategy feature a double Mukaiyama Michael addition/elimination, a Helquist annulation, two substrate-controlled facial-selective hydrations, and a pinacol rearrangement. The described syntheses not only achieved these natural products in an efficient manner, but also provided insight into the biosynthetic relationship between the two different skeletons.

The Name is Benzoic anhydride. Through research, I have a further understanding and discovery of 93-97-0.

Platelet thrombosis is the main pathogeny resulting in the low curability of ischemic stroke, a leading cause of mortality and disability worldwide. Metformin, a biguanide derivative that is the first-line oral medicine for type 2 diabetes, alleviates the severity of ischemic stroke in diabetic patients and suppresses platelet activation in experimental animal model. However, the clinical implementation of commercial biguanide analogs for stroke related to platelet thrombosis remains challenging due to its weak potency, poor pharmacokinetic characteristics and possible hypoglycemia. Here, twenty-three biguanide derivatives were designed and synthesized based on the principles of bioisosteres. These derivatives were evaluated for the activity of antiplatelet thrombosis in vivo. We found that N-tri-fluoromethanesulfonyl biguanide derivative, compound b10, uniquely prevented cerebral infarction as well as neuronal function injury, and significantly decrease the mortality rate of ischemic stroke in the middle cerebral artery occlusion mice without significant side effects. We verified that b10 directly inhibited platelets thrombus formation and decreased the compactness of stroke thrombi. Particularly, b10 exhibited good potency to inhibit human platelet activation including platelet aggregation, adhesion, pseudopodia formation, integrin GPIIb/IIIa activation, CD62P expression and clot retraction. Meanwhile, the pharmacokinetics assessment showed that b10 had satisfying pharmacological characteristics including a longer duration and a higher oral absorption ratio than its parent compound. In addition, b10 remarkably ameliorated not only stroke related to platelet thrombosis but also carotid artery thrombus formation. It is concluded that the novel potent antiplatelet thrombotic agent derived from biguanide is a promising candidate for stroke treatment. (C) 2020 Elsevier Masson SAS. All rights reserved.

The Rh-catalyzed C-H alkylation of benzylamine derivatives with unactivated 1-alkenes that proceeds via a picolinamide directing group is reported. The crucial role of an acid additive in this transformation is confirmed. Aromatic acids showed high linear selectivity, and aliphatic acids provided branched alkylation products as the major product. The reaction has a broad scope for benzylamines and alkenes. Deuterium labeling experiments suggest that a Rh-carbene intermediate is involved in the case of linear product formation. A different reaction pathway, however, appears to be involved in the case of branched alkylation products, and this pathway also appeared to be a minor pathway in linear-selective reactions.

The methoxy-, hydroxy-, and carbonyl-substituted benzenes are the simplest fragments from the lignin separation feedstocks. Extensive experimental thermochemical studies of these compounds were carried out, including combustion calorimetry, vapor pressure measurements, and differential scanning calorimetry. We have collected available primary experimental results on enthalpies of formation and vapor pressures as well as on phase transitions, liquid-gas, liquid-solid, and crystal-liquid. These data were evaluated using empirical, semiempirical, and quantum chemical methods. The consistent sets of evaluated thermodynamic data were used to design the method for predicting enthalpies of vaporization and enthalpies of formation of di- and trisubstituted benzenes. It is expected that parameters and pairwise interactions will be transferable to predict the thermochemical properties of poly methoxy-substituted and poly hydroxysubstituted benzenes that appear in reaction products of lignin transformations in the value-adding chemicals and materials.

Tetraarylethenes are obtained by acid-induced coupling of vinyl triazenes with aromatic compounds. This new C-H activation route for the synthesis of aggregation-induced emission luminogens is simple, fast, and versatile. It allows the direct grafting of triarylethenyl groups onto a variety of aromatic compounds, including heterocycles, supramolecular hosts, biologically relevant molecules, and commercial polymers.

This article reports the first example of a 2-pyridone accelerated non-directed C-H cyanation with an arene as the limiting reagent. This protocol is compatible with a broad scope of arenes, including advanced intermediates, drug molecules, and natural products. A kinetic isotope experiment (k(H)/k(D) =4.40) indicates that the C-H bond cleavage is the rate-limiting step. Also, the reaction is readily scalable, further showcasing the synthetic utility of this method.
