Disinfection of gloved hands during the COVID-19 pandemic

Background: Disinfection of gloves can be used during a pandemic situation when performing various procedures on the same patient or when removing personal protective equipment. If performing glove disinfection, there is a need to check the compatibility of gloves with the disinfectant product used. Aim: To test the resistance of nitrile gloves to various disinfectant solutions. Methods: One hundred percent powder-free nitrile gloves, composed of nitrile butadiene rubber compounds, were exposed to various disinfectants to analyse resistance. The seven most commonly used disinfectant solutions in the healthcare field were selected for testing. The effects of each disinfectant were analysed in comparison with the control group (untreated glove). For tensile testing, the thickness of each test specimen was measured with a micrometer. Findings: Bleach solution decreased the breaking load of gloves, although to a lesser extent than disinfectants that contained ethanol. Conclusion: Disinfectants that contain alcohol decrease the breaking load of nitrile gloves. (C) 2020 The Healthcare Infection Society. Published by Elsevier Ltd. All rights reserved.

Degradation of neonicotinoid insecticide acetamiprid by two different nitrile hydratases of Pseudaminobacter salicylatoxidans CGMCC 1.17248

Acetamiprid is a neonicotinoid insecticide used worldwide that has caused environmental pollution and adverse effects on ecosystems. Here, a novel bacterium, Pseudaminobacter salicylatoxidans CGMCC 1.17248, was isolated to rapidly degrade acetamiprid to IM-1-2 via hydration. Gene cloning and overexpression demonstrated that two nitrile hydratases, AnhA and AnhB, converted acetamiprid to IM-1-2. Escherichia coli overexpressing AnhA and AnhB degraded 98.1% and 94.0% of acetamiprid (1.0 mmol L-1) in 5 min and 8 h, respectively. The pure AnhA and AnhB had a V-max value of 14.12 and 1.20 mu mot mg(-1 )min(-1), respectively, and a K-m value of 1.02 mmol L-1 and 2.95 mmol L-1, respectively. Compared with AnhA, AnhB had broad pH stability, as well as metal ions and organic solvents tolerance. Expression of AnhA and AnhB was induced by decreasing the nutrient concentration of culture broth and addition of urea and therefore significantly enhanced acetamiprid degradation of CGMCC 1.17248. qPCR indicated that the expression of AnhA and AnhB under the cultured conditions of 1/15 lysogeny broth or 0.5% urea addition was improved by from 2.2 to 5.3 times. The results presented herein will facilitate development of bioremediation agents for acetamiprid pollution and understanding of the functional role of bacterial nitrile hydratase.

Clarification of the USP compendial procedure for phenoxybenzamine hydrochloride via updating impurity profiles

The current United States Pharmacopeia-National Formulary (USP-NF) and the British Pharmacopoeia phenoxybenzamine (PBA) hydrochloride drug substance and drug product monographs describe an HPLC procedure for the determination of a specified impurity tertiary amine phenoxybenzamine and use the resolution of an unknown related substance from PBA as a system suitability criterion; however, neither structural information of the unknown related substance is provided nor reference standards of the two impurities are available. The ambiguity in pharmacopeias poses difficulties in implementing the procedure for quality control. To clarify the degradation pathways, and incorporate the impurity profile of PBA into the USP monographs, the degradation of PBA was revisited. PBA undergoes rapid degradation in neutral or basic aqueous solutions to generate the tertiary amine phenoxybenzamine as the predominant degradation product, which was confirmed as phenoxybenzamine hydroxide (PBA-OH). In addition, the unknown related substance was proposed as the phenoxybenzamine nitrile (PBA-CN) on the basis of LC-MS studies. The identity of PBA-CN was unambiguously verified via chemical synthesis, HPLC and NMR analyses. A stability-indicating method was developed and validated for the determination of PBA and its impurities, and was used to support USP monograph modernization. (C) 2020 Elsevier B.V.

Rational Design of CYP3A4 Inhibitors: A One-Atom Linker Elongation in Ritonavir-Like Compounds Leads to a Marked Improvement in the Binding Strength

Inhibition of the major human drug-metabolizing cytochrome P450 3A4 (CYP3A4) by pharmaceuticals and other xenobiotics could lead to toxicity, drug-drug interactions and other adverse effects, as well as pharmacoenhancement. Despite serious clinical implications, the structural basis and attributes required for the potent inhibition of CYP3A4 remain to be established. We utilized a rational inhibitor design to investigate the structure-activity relationships in the analogues of ritonavir, the most potent CYP3A4 inhibitor in clinical use. This study elucidated the optimal length of the head-group spacer using eleven (series V) analogues with the R-1/R-2 side-groups as phenyls or R-1-phenyl/R-2-indole/naphthalene in various stereo configurations. Spectral, functional and structural characterization of the inhibitory complexes showed that a one-atom head-group linker elongation, from pyridyl-ethyl to pyridyl-propyl, was beneficial and markedly improved K-s, IC50 and thermostability of CYP3A4. In contrast, a two-atom linker extension led to a multi-fold decrease in the binding and inhibitory strength, possibly due to spatial and/or conformational constraints. The lead compound, 3h, was among the best inhibitors designed so far and overall, the strongest binder (K-s and IC50 of 0.007 and 0.090 mu M, respectively). 3h was the fourth structurally simpler inhibitor superior to ritonavir, which further demonstrates the power of our approach.

An updated asymmetric total synthesis of (+)-tronocarpine

An updated route for the asymmetric total synthesis of (+)-tronocarpine is presented. By a careful modification of the synthetic strategies and methods for the construction of azepanone ring and for the incorporation of acetyl side group at C-20 based on our experiences for the synthesis of chippiine-dippinine type indole alkaloids, the synthesis of (+)-tronocarpine could be shortened from 15 longest linear sequences (LLSs) to 11 LLSs starting from an easily prepared intermediate. The new synthetic route presented herein would provide a more efficient synthesis of (+)-tronocarpine as well as its analogues for biological evaluation which remained unexplored due to the paucity of natural sources.

Direct Catalytic Asymmetric Addition of alpha-Fluoronitriles to Aldehydes

A fluorine-containing tetrasubstituted stereogenic center is a highly valued structural feature in medicinal chemistry. Herein, we describe the direct coupling of racemic alpha-fluoronitriles and aldehydes promoted by a chiral Cu-I/Barton’s base catalytic system, delivering alpha-tetrasubstituted alpha-fluoro-beta-hydroxynitriles with satisfactory stereoselection. The stereochemical course was positively biased by the combined use of asymmetrical achiral thiourea as a supplementary ligand for Cu-I, which significantly enhanced the stereoselectivity. Both aromatic and aliphatic aldehydes were implemented to provide densely and stereoselectively functionalized chiral building blocks with aliphatic and aromatic tails.
