Behav Pharmacol 2021 Jul 26. Epub 2021 Jul 26.

Department of Pharmacology, University of Texas Health, San Antonio, Texas, USA.

An attempt to determine the receptor selective nature of some of nicotine's behavioral effects was undertaken through the evaluation of the ability of two nicotinic α4β2*-selective receptor agonists to produce nicotine-like effects and modify rates of responding in a discrimination assay and in an aversive stimulus assay. A group of eight rats was trained to discriminate the presence of 1 mg/kg nicotine base. Another group of 4-6 rats was trained to report the aversive effects of nicotine by selecting a lever that produced one food pellet over a second lever that produced two food pellets and an intravenous injection of nicotine.

Targeting Mycobacterium tuberculosis response to environmental cues for the development of effective antitubercular drugs.

PLoS Biol 2021 Jul 28;19(7):e3001355. Epub 2021 Jul 28.

Department of Molecular Biology and Microbiology, Tufts University School of Medicine, Boston, Massachusetts, United States of America.

Sensing and response to environmental cues, such as pH and chloride (Cl-), is critical in enabling Mycobacterium tuberculosis (Mtb) colonization of its host. Utilizing a fluorescent reporter Mtb strain in a chemical screen, we have identified compounds that dysregulate Mtb response to high Cl- levels, with a subset of the hits also inhibiting Mtb growth in host macrophages. Structure-activity relationship studies on the hit compound "C6," or 2-(4-((2-(ethylthio)pyrimidin-5-yl)methyl)piperazin-1-yl)benzo[d]oxazole, demonstrated a correlation between compound perturbation of Mtb Cl- response and inhibition of bacterial growth in macrophages.

IFITM proteins that restrict the early stages of respiratory virus infection do not influence late-stage replication.

J Virol 2021 Jul 28:JVI0083721. Epub 2021 Jul 28.

Department of Microbiology and Immunology, The University of Melbourne at The Peter Doherty Institute for Infection and Immunity, 792 Elizabeth St, Melbourne, Victoria 3000, Australia.

Interferon-induced transmembrane (IFITM) proteins inhibit a broad range of enveloped viruses by blocking entry into host cells. We used an inducible overexpression system to investigate if IFITM1, IFITM2 and IFITM3 could modulate early and/or late stages of influenza A virus (IAV) or parainfluenza virus (PIV)-3 infection in human A549 airway epithelial cells. IAV and PIV-3 represent respiratory viruses which utilise distinct cellular entry pathways. Read More

MoS nanosheets/silver nanoparticles anchored onto textile fabric as "dip catalyst" for synergistic p-nitrophenol hydrogenation.

Environ Sci Pollut Res Int 2021 Jul 27. Epub 2021 Jul 27.

Laboratory of Applied Organic Chemistry, Faculty of Science and Techniques, Sidi Mohamed Ben Abdellah University, 2202, Fes, Morocco.

Attaining a synergistic merge between the performance of homogenous catalysts and the recyclability of heterogeneous catalysts remains until now a concerning issue. The main challenge is to design efficient, low-cost catalyst with outstanding reusability, facile recovery, and ease of retrieval and monitoring between the reuses. Despite the vast efforts in the development of silver nanoparticle-based catalyst for the reaction of hydrogenation of 4-nitrophenol, the aforementioned criteria are infrequently found in a chosen system.

Calmodulin Antagonist W-7 Enhances Intermediate Conductance Ca- Sensitive Basolateral Potassium Channel (IK) Activity in Human Colonic Crypts.

J Membr Biol 2021 Jul 27. Epub 2021 Jul 27.

Leeds Institute of Medical Research at St James, St James University Hospital, Beckett Street, Leeds, LS9 7TF, UK.

Intermediate conductance potassium (IK) channels are exquisitively Ca sensitive, intracellular Ca regulating channel activity by complexing with calmodulin (CaM), which is bound to the cytosolic carboxyl tail. Although CaM antagonists might be expected to decrease IK channel activity, the effect of W-7 in human T lymphocytes are conflicting. We therefore evaluated the effect of W-7 on basolateral IK channels in human colonic crypt cells. Read More
