Two new thiadiazole imidazolium salicylidene Schiff bases (TISSBs) were successfully synthesized, and their structures were analyzed comprehensively using spectroscopic techniques. The results of the MTT assay showed that TISSB2 was the safest and most effective anti-breast cancer agent. The anti-angiogenic activity of TISSB2 was evaluated using tests in Ehrlich ascites carcinoma (EAC)-bearing Swiss albino mice.

This research explores the potential of encapsulating thyme essential oil (TEO) and thymol (TH) into quaternized chitosan nanocapsules to combat SARS-CoV-2. Initially, the bioactive materials, TH and TEO, were extracted from and then structurally and phytochemically characterized by spectral and GC-MS analyses. Meanwhile, -quaternized ultrasonic-mediated deacetylated chitosan (QUCS) was successfully synthesized and characterized.

Recently, molecular hybrids of two or more active pharmacophores have shown promise for designing and synthesizing anticancer drugs. Herein, a new multifunctional hybrid (PAHMQ), combining azobenzene and quinoline pharmacophores, and its M(ii) complexes (MPAHMQ) have been successfully developed and structurally characterized. The MTT assay revealed CuBHTP as the most efficient and safe breast cancer treatment, with an IC of 11.

Article Synopsis
  • Industrial wastewater significantly pollutes water resources, prompting the need for effective treatment methods, like coagulation-flocculation, to remove contaminants.
  • Natural coagulants and flocculants (NC/Fs), though cost-effective and biodegradable, are often overlooked for large-scale industrial applications, with most existing research focusing on plant-based sources.
  • This review broadens the exploration of NC/Fs by examining alternative natural materials, detailing preparation techniques, discussing recent studies, and highlighting the potential of magnetic-natural coagulants/flocculants (M-NC/Fs) in large-scale effluent treatment systems.

Two novel ethanoanthracene-11,12-dicarbohydrazide derivatives ','-bis(()-4-hydroxybenzylidene)-9,10-dihydro-9,10-ethanoanthracene-11,12-dicarbohydrazide (HHEH) and ','-bis(()-4-methoxybenzylidene)-9,10-dihydro-9,10-ethanoanthracene-11,12-dicarbohydrazide (HMEH) were synthesized and characterized by FT-IR spectroscopy, electronic spectra, and NMR spectroscopy. These two derivatives as novel anticorrosion inhibitors for N80 steel in a 3.5% NaCl solution were studied using electrochemical techniques including potentiodynamic polarization (PP), electrochemical impedance spectroscopy (EIS), and electrochemical frequency modulation (EFM).

A novel potentiometric sensor was developed and optimized for the quantitative analysis of ephedrine in non-prescribed herbal supplements used as adjunctive therapy for weight loss. An initial optimization study aimed to reach the optimum membrane composition, sensor assembly, and experimental conditions. The study evaluated the effect of several factors on the sensor performance including different ion-exchangers, plasticizers, ionophores, membrane thicknesses, soaking solution concentrations, soaking time intervals, and pH.

Article Synopsis
  • A bimetallic Cr-Mg-MOF was successfully created using a solvothermal method and modified with varying amounts of phosphomolybdic acid (PMA) through wet impregnation.
  • The study revealed that doping with magnesium increased the surface area and enhanced the adsorption performance of the Cr-Mg-MOF compared to other metal-organic frameworks (MOFs).
  • Catalytic tests showed that PMA-loaded Cr-Mg-MOFs exhibited peak catalytic activity at 75 wt%, making them promising candidates for environmentally friendly acid-catalyzed organic reactions.

Typical highly porous metal-organic framework (MOFs) materials based on chromium benzenedicarboxylates (Cr-BDC) were prepared through a one-pot hydrothermal synthesis, and were then modified by loading the appropriate ratio of sulfamic acid (SA) using a simple impregnation technique. Pure and modified MIL-101 was characterized by XRD, TEM, SEM and FT-IR measurements. TEM and SEM measurements confirmed that the MIL-101 particles preserved their regular octahedral structure after loading with different weight contents of sulfamic acid.
