Computational analyses of toxicological processes enables high-throughput screening of chemical substances and prediction of their endpoints in biological systems. In particular, quantitative structure-activity relationship (QSAR) models have been increasingly applied to assess the environmental effects of a plethora of toxic materials. In recent years, some more highlighted types of toxicants are endocrine disruptors (EDs, which are chemicals that can interfere with any hormone-related metabolism). Because EDs may significantly affect animal development and reproduction, rapidly predicting the adverse effects of EDs using in silico techniques is required. This study presents an in silico method to generate prediction data on the effects of representative EDs in aquatic vertebrates, particularly fish species. The protocol describes an example utilizing the automated workflow of the QSAR Toolbox software developed by the Organization for Economic Co-operation and Development (OECD) to enable acute ecotoxicity predictions of EDs. As a result, the following are determined: (1) calculation of the numerical correlations between the concentration for 50% of lethality (LC50) and octanol-water partition coefficient (K-ow), (2) output performances in which the LC50 values determined in experiments are compared to those generated by computations, and (3) the dependence of estrogen receptor binding affinity on the relationship between K-ow and LC50.

Quality Control of 1-Phenylurea. I found the field of Oncology; Respiratory System very interesting. Saw the article Nivolumab and brain metastases in patients with advanced non-squamous non-small cell lung cancer published in 2019.0, Reprint Addresses Bronte, G (corresponding author), Ist Sci Romagnolo Studio & Cura Tumori IRST IRCCS, Dept Med Oncol, Via Maroncelli 40, I-47014 Meldola, FC, Italy.. The CAS is 64-10-8. Through research, I have a further understanding and discovery of 1-Phenylurea.

Objectives: Brain metastases are common among patients with non-squamous non-small-cell lung cancer (NSCLC) and result in a poor prognosis. Consequently, such patients are often excluded from clinical trials. In Italy an expanded access program (EAP) was used to evaluate nivolumab efficacy and safety in this sub population outside a clinical trial. Materials and methods: In this EAP, nivolumab was available for patients with non-squamous NSCLC in progression after at least one systemic treatment for stage IIIB/IV disease. Nivolumab 3 mg/kg was administered intravenously every 2 weeks. Patients with brain metastases could be included if they were asymptomatic, neurologically stable and either off corticosteroids or on a stable or decreasing dose of <= 10 mg/day prednisone. Results: 409 out of 1588 patients included had asymptomatic or controlled brain metastases. A median of 7 doses (range 1-45) were delivered. Median follow-up was 6.1 months (range 0.1-21.9). The disease control rate was 39%: 4 patients had a complete response, 64 a partial response and 96 showed stable disease. At baseline, 118 patients were on corticosteroids and 74 were undergoing concomitant radiotherapy. The median overall survival in this subpopulation was 8.6 months (95% CI: 6.4-10.8). 337 discontinued treatment for various reasons, 23 (7%) of whom due to adverse events, in line with that observed in the overall population and in previous studies. Conclusions: Our results confirm that nivolumab is active in non-squamous NSCLC patients with brain metastases, despite their poor prognosis. Its safety profile is also concordant with results in the EAP overall population and in patients with other malignancies. Quality Control of 1-Phenylurea.

The Name is 1-Phenylurea. Through research, I have a further understanding and discovery of 64-10-8.

Four polar stationary phases (ethylene-bridged hybrid silica, cyanopropyl, 2-ethylpyridine, and zwitterionic sulfobetaine) have been characterized in supercritical fluid chromatography (SFC) by linear free energy relationships (LFER) method with an extended set of Abraham’s descriptors. Temperature (25-55 degrees C) and pressure (110-180 bar) effects on analyte retention, separation selectivity and LFER-coefficients of chromatographic systems have been studied using the 89 test compounds of various chemical classes and carbon dioxide – methanol (9:1 v/v) binary solvent as a mobile phase. It was found that for the selected stationary phases temperature and pressure had only moderate effects on selectivity. The retention times of all analytes decrease, as can be expected, if the pressure rises at the isothermal conditions due to the increase of the fluid density and its eluting power. The effect of temperature on retention is complicated and depends both on the chemical class of analyzed compounds and the stationary phase type. Temperature and pressure variations lead to small changes in the LFER-coefficients, and general trends observed do not depend much on the stationary phase type. It may be difficult to interpret the LFER-analysis results because of the evident, more significant chromatographic phenomena. (C) 2019 Elsevier B.V. All rights reserved.

The development of methodologies for inducing and tailoring enantioselectivities of catalysts is an important issue in asymmetric catalysis. In this work, we demonstrate for the first time that chiral molecular catalysts can be boosted from completely nonselective to highly enantioselective when installed in nanostructured metal-organic frameworks (MOFs). Exfoliation of layered crystals is one of the most direct synthetic routes to unitrathin nanosheets, but its use in MOFs is limited by the availability of layered MOFs. We illustrate that layered MOFs can be designed using ligand-capped metal clusters and angular organic linkers. This leads to the synthesis of two three-dimensional (3D) layered porous MOFs from Zn-4-p-tert-butylsulfonyl calix[4]arene and chiral angular 1,1′-binaphthol/-biphenol dicarboxylic acids, which can be ultrasonic exfoliated into one- and two-layer nanosheets. The obtained MOF materials are efficient catalysts for asymmetric cascade condensation and cyclization of 2-aminobenzamide and aldehydes to produce 2,3-dihyroquinazolinones. While both binaphthol and biphenol display no enantioselectivity, restriction of their freedom in the MOFs leads to 56-90% and 46-72% ee, respectively, which are increased to 72-94% and 64-82% ee after exposure to external surfaces of the flexible nanosheets. Moreover, the MOF crystals and nanosheets exhibit highly sensitive fluorescent enhancement in the presence of chiral amino alcohols with enantioselectivity factors being, respectively, increased up to 1.4 and 2.3 times of the values of the diols, allowing them to be utilized in chiral sensing. Therefore, the observed enantioselectivities increase in the order organocatalyst < MOF crystals < MOF nanosheets in both catalysis and sensing. This work not only provides a strategy to make 3D layered MOFs and their untrathin nanosheets but also paves the way to utilize nanostructured MOFs to manipulate enantioselectivities of molecular catalysts.

The site-selective modifications of quinazolinones constitute a pivotal topic in drug discovery and material science. Herein, we describe the rhodium(III)-catalyzed C-H amidation of 2-aryl quinazolin-4(3H)-ones with a range of nitrene surrogates including dioxazolones, organic azides, andN-methoxyamides. Complete site-selectivity and functional group tolerance are observed. Notably, the large-scale reaction and late-stage functionalization highlight the synthetic potential of the developed protocol. Combined mechanistic investigations elucidate a plausible reaction mechanism of this process.

HPLC of Formula: C7H8N2O. I found the field of Pharmacology & Pharmacy very interesting. Saw the article 2,4-Disubstituted quinazolines targeting breast cancer cells via EGFR-PI3K published in 2019, Reprint Addresses Zhang, QR (corresponding author), Zhengzhou Univ, Sch Pharmaceut Sci, Zhengzhou 450001, Henan, Peoples R China.; Liu, HM (corresponding author), Zhengzhou Univ, Zhengzhou 450001, Henan, Peoples R China.. The CAS is 88-68-6. Through research, I have a further understanding and discovery of 2-Aminobenzamide.

A series of novel 2,4-disubstituted quinazolines were synthesized and evaluated for their anti-tumor activity against five human cancer cells (MDA-MB-231, MCF-7, PC-3, HGC-27 and MGC-803) using MIT assay. Among them, compound 9n showed the most potent cytotoxicity against breast cancer cells. Compound 9n also significantly inhibited the colony formation and migration of MDA-MB-231 and MCF-7 cells. Meanwhile, compound 9n induced cell cycle arrest at G1 phase and cell apoptosis, as well as increased accumulation of intracellular ROS. Furthermore, compound 9n exerted anti-tumor effects in vitro via decreasing the expression of anti-apoptotic protein Bcl-2 and increasing the pro-apoptotic protein Bax and p53. Mechanistically, compound 9n markedly decreased p-EGFR and p-PI3K expression, which revealed that compound 9n targeted breast cancer cells via interfering with EGFR-PI3K signaling pathway. Molecular docking suggested that compound 9n could indeed bind into the active pocket of EGFR. All the findings suggest that compound 9n might be a valuable lead compound for anti-tumor agents targeting breast cancer cells. (C) 2019 Elsevier Masson SAS. All rights reserved.

Sorption of pesticides by soils holds a major consequence for their fate in the environment. As such, sorption coefficient (K-d/K-oc), which is derived from laboratory or field experiments is a fundamental parameter used in almost all screening tools to evaluate the fate or mobility of these compounds. The value of this coefficient is controlled by many soil and solute specific properties, as well as environmental variables. Soft computing techniques such as Adaptive Neuro-Fuzzy Inference System (ANFIS) have been successfully used to predict the equilibrium partitioning of many compounds in various engineered systems. Application of these techniques to natural systems such as soils is however lacking. Here, we present the use of ANFIS in predicting the sorption per unit mass of soil, Q(e), used in the calculation of K-d/K-oc of compounds in soils. In a previous study, we collected data associated to the adsorption of five phenylurea herbicides in 18 tropical soils. Here, we analysed such data and based on established correlations, nine variables were selected as potential input vectors (i.e., six soil properties, two herbicides molecular descriptors and initial solute concentrations). A total of 255 ANFIS models of one to eight input vectors were elaborated under 10-fold cross-validation. Multiple linear regression (MLR) models were similarly developed, and compared with the ANFIS in terms of mean absolute error (MAE), root-mean-square error (RMSE) and coefficient of determination (R-2). The best ANFIS model (M94) has an MAE(test), RMSEtest and R-test(2) of 3.43 +/- 0.43, 4.94 +/- 0.80 and 0.95 +/- 0.01, respectively, whereas the best MLR model (M13) returned an MAE, RMSE and R-2 of 7.71 +/- 0.13, 10.11 +/- 1.21 and 0.81 +/- 0.01, respectively. We observed that generally ANFIS performed better than MLR regarding both accuracy and interpretability. Accordingly, we recommend the use of ANFIS for predicting the sorption coefficients of phenylurea herbicides (PUHs) in soils.
