Chemical, Spectral, Biological, and Toxicological Studies of Some Benzene Derivatives Used in Pharmaceuticals: In Silico Approach

Journal of Tropical Pharmacy and Chemistry
The immune system of humans is impacted by many drugs. Chemicals that have a gender-bending impact on boys, were synthesized, their use spread, and as a consequence, they entered the ecology, the food chain, and eventually ended up in blood or human ...

SYNTHESIS AND ANTINEOPLASTIC ACTIVITY OF CERTAIN TRIAZENE AND TRIAZENO-ACRIDINE COMBILEXIN DERIVATIVES [PDF]

Bulletin of Pharmaceutical Sciences. Assiut University, 2007
Four series of bifunctional ligands have been synthesized as DNA-binding combilexins. These novel agents contain a triazenobenzene sulfonamide linker moiety that is attached to an intercalating acridine or acridone chromophore by a functionalized amide ...

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Design of Jacob’s ladder-based teaching aids for illustrating the dualities of benzene derivatives

Chemistry Teacher International
The dualities of benzene derivatives often make basic organic chemistry challenging for students. This includes the relationship between full structural and line-angle formulas, the distinctions between preferred and systematic IUPAC names for benzene ...

Identifying and characterising a plant GH1 β‐glucosidase that exhibits hydrolytic activity on N‐linked glucopyranoside

FEBS Open Bio, EarlyView.
We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...

Demonstrating Vibrational Current Generation With a Self‐Assembled Bioelectret

Advanced Functional Materials, EarlyView.
Vacuum‐deposited films of the plant‐derived molecule, Baicalein, form a self‐assembled bioelectret exhibiting spontaneous orientation polarization and a giant surface potential. The films induce alternating current during the vibration of a movable electrode without charging treatments. Hydrocarbon protection enhances the air stability of the Baicalein

Mechanistic Control of C─H Bond Activation and C─C Coupling in Light‐Driven Methane Conversion to C2+ Products over Multifunctional Photocatalysts

Advanced Functional Materials, EarlyView.
Methane photocatalytic activation under mild conditions remains a formidable challenge in the synthesis of solar fuels. In this review, we emphasize the growing importance of multifunctional materials and hybrid systems within a unified mechanistic framework that integrates selective C─H bond activation, formation and control of intermediates, C─C ...

Acute toxicity and anti-inflammatory activity of bis-thiourea derivatives

Open Chemistry
In the current work, bis-thiourea derivatives have been synthesized through condensation reaction between isothiocynates and diamines in dry acetone to form SK1 (1,2-bis(N-benzoylthioureido) benzene), SK2 (1,3-bis(N-benzoylthioureido) benzene), and SK3 ...

Bismuth‐Based Photocatalysts for Water Remediation: Design Strategies, Mechanisms, and Challenges

Advanced Functional Materials, EarlyView.
This review highlights representative design strategies for bismuth‐based semiconductor photocatalysts in solar‐driven water purification. Emphasis is placed on electronic structure regulation, oxygen‐vacancy engineering, and interfacial coupling to enable efficient full‐spectrum light utilization, improved charge separation, and selective oxidation in
