Design, Synthesis, and Photophysical Studies of Functionalized Polyaromatic Isonitriles as Visible Light Photoredox Catalysts

European Journal of Organic Chemistry, EarlyView.
A new series of structurally rich polyaromatic isonitriles is presented as photoredox catalysts. Their photophysical properties are investigated by UV–Vis absorption and fluorescence measurements, combined with experimental and theoretical studies to evaluate both ground‐ and excited‐state redox properties.

Using Quinolin-4-Ones as Convenient Common Precursors for a Metal-Free Total Synthesis of Both Dubamine and Graveoline Alkaloids and Diverse Structural Analogues

Molecules
The Rutaceae family is one of the most studied plant families due to the large number of alkaloids isolated from them with outstanding biological properties, among them the quinoline-based alkaloids Graveoline 1 and Dubamine 2.

Synthesis and biological evaluation of novel 3-(quinolin-4-ylamino)benzenesulfonamides as carbonic anhydrase isoforms I and II inhibitors

Journal of Enzyme Inhibition and Medicinal Chemistry, 2019
Carbonic anhydrases (CAs, EC 4.2.1.1) are crucial metalloenzymes that are involved in diverse bioprocesses. We report the synthesis and biological evaluation of novel series of benzenesulfonamides incorporating un/substituted ethyl quinoline-3 ...

Pharmacological interactions of anti-microbial agents in odontology [PDF]

, 2009
In this third article we describe the pharmacological interactions resulting from the use of anti-microbial agents. Although the antimicrobials prescribed in odontology are generally safe they can produce interactions with other medicaments which can ...

Remarkable Formation of Indene Derivatives Upon Friedel–Crafts Acylation Reactions

European Journal of Organic Chemistry, EarlyView.
This shows indene derivatives. Under the reaction conditions of a Friedel–Crafts acylation, alkyl benzenes underwent an unprecedented cyclopentannulation furnishing indene derivatives. Alkylbenzene derivatives react with two equivalents of pivaloyl chloride (PivCl) in the presence of aluminum trichloride under formation of indene derivatives with up to

Preparation of 4,7‐Dihalobenzo[b]Thiophene Derivatives Containing Iodine Atoms and Their Cross Coupling With Arylethynes

Journal of Heterocyclic Chemistry, EarlyView.
Quasi T‐shaped three‐way benzo[b]thiophene scaffolds, containing iodine atom(s) at the 4‐ and/or 7‐position, were prepared by several methods such as silica gel‐assisted cyclization. The iodobenzo[b]thiophenes thus prepared were subjected to Sonogashira cross couplings to give various ethynylbenzo[b]thiophenes.

High‐Efficiency and Long‐Lifetime Narrowband Green MR‐TADF OLEDs Enabled by Distinct Molecular Design Strategies

Journal of the Society for Information Display, EarlyView.
Two complementary molecular design strategies are proposed to independently enhance operational stability and device efficiency in MR‐TADF OLEDs. Strengthening the cationic bond dissociation energy (BDEf+) improves intrinsic molecular robustness and prolongs device lifetime, although a PSF‐based efficiency‐oriented design with high molar absorption ...

Multi‐Targeting Ligands as Prospective Therapeutics for Alzheimer's Disease, a Prevalent Neurodegenerative Disorder: Mechanistic Insights, Emerging Targets and Drug Discovery Campaigns

Medicinal Research Reviews, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a debilitating neurodegenerative condition characterized by progressive cognitive impairment, memory deterioration, and neuronal dysfunction. Its complex pathophysiology involves multiple interlinked processes, including amyloid‐β (Aβ) aggregation, tau hyperphosphorylation, oxidative stress, neuroinflammation ...
