In search of unprecedented tri and/or tetrapod pharmacophoric conjugates, a series of 32 new 4-ethyl-1-benzo[][1,4]diazepin-2(3)-ones were synthesized and properly elucidated using MS, IR, NMR, and elemental analysis. investigation of 11 compounds of this series, using a panel of two human tumor cell lines namely; human breast adenocarcinoma (MCF-7), and human colorectal carcinoma (HCT-116), revealed promising cytotoxic activities. Among all synthesized compounds, analogue displayed maximum cytotoxicity with IC values of 16.19 ± 1.35 and 17.16 ± 1.54 μM against HCT-116 and MCF-7, respectively, compared to standard drug doxorubicin.

This study quantitatively evaluated the adsorption performance of natural bentonite for removing three dye classes-cationic (Basic dye: BEZACRYL RED GRL), anionic (Reactive dye: AVITERA LIGHT RED SE), and non-ionic (Disperse dye: BEMACRON BLUE HP3R) from synthetic textile wastewater. Batch adsorption experiments were conducted under varying conditions of contact time (15-90 min), adsorbent dosage (20-60 g L⁻), pH (4 and 12), and temperature (25-100 °C), with dye concentrations quantified by UV-Vis spectroscopy. At a contact time of 30 min and room temperature (25 °C), maximum removal efficiencies reached 99.

A convenient protocol for the synthesis of selenated benzoxepine derivatives via iron(III)-catalyzed 7-endo-trig cyclization has been first established via reaction of 1,7-diene containing nonactivated allyl and dialkyl diselenides under room temperature and air conditions. Research has shown that different dialkyl diselenides could react with a wide range of 1,7-diene to achieve seven-membered products in good to excellent yields. Furthermore, this synthesis was directed to obtain the desired target products, indicating that this approach has an excellent chemical selectivity.

Tungsten disulfide (WS), a two-dimensional adsorbent material, has garnered great attention in removing lead ions (Pb) from water due to their extensive exposed adsorption sites. However, WS nanosheets inevitably agglomerated and stacked during the preparation and adsorption process, leading to reduced adsorption efficiency. Current method of enhancing WS dispersion is mainly blending with synthetic polymers, but these synthetic polymers themselves do not possess adsorption properties, resulting adsorption effect enhancement poorly.

Transition metal fluorides because of the high electronegativity of fluorine may enhance the local electron density of the metal sites and promote water molecule dissociation and charge transfer. However, enhancing the intrinsic activity of fluorides to improve material stability remains a challenge. Herein, we develop an innovative four-step synthetic strategy (electrochemical deposition → co-precipitation → ligand exchange → in situ fluorination) to engineer three-dimensional porous Fe-doped CoF nanocubes vertically anchored on MXene (Fe-CoF/MXene/NF).

In this study, we develop a hyaluronic-tannic acid (HA-TA) hydrogel loaded with Cu nanoparticles attach to MXene (MXene@Cu) to explore its potential as a targeted breast cancer treatment. The MXene@Cu nanosheets exhibit activity in depleting glutathione (GSH) and inducing reactive oxygen species (ROS) through the Fenton-like reaction. They can down-regulate the activity of glutathione peroxidase 4 (GPX4), leading to the accumulation of lipid peroxides (LPO) and inducing ferroptosis in tumor cells.
