AI Article Synopsis
- New fluorophores were developed from benzanthrone derivatives, specifically by substituting a bromine atom with secondary cyclic amines.
- The inclusion of a nitro group enhances the reaction and improves the absorption and luminescent properties of these compounds in different organic solvents.
- These new dyes show increased hyperpolarizability and have potential uses in optical limiter devices and optoelectronics.
Article Abstract
In the present study, new fluorophores based on disubstituted benzanthrone derivatives were designed starting from 9-nitro-3-bromobenzanthrone with nucleophilic substitution of the bromine atom with some secondary cyclic amines. It has been found that this reaction is positively affected by the presence of a nitro group in comparison with 3-bromobenzanthrone. The new compounds exhibit intense absorption and pronounced luminescent properties in various organic solvents. In this regard, their photophysical properties were evaluated with an experimental study of the solvatochromic behavior of the obtained compounds in various solvents. It has recently been found that the addition of an electron-withdrawing nitro group to the benzanthrone core increases its first- and second-order hyperpolarizability. Such dyes can be used in the fabrication of optical limiter devices. Therefore, the developed fluorescent molecules have a potential prospect for extensive application in optoelectronics.

In this study, we present the synthesis of a silver nanocomposite by utilizing a β-cyclodextrin (βCD) polymer anchored onto the surface of magnetic g-CN (referred to as g-CN-FeO/βCD-Ag). The structure and composition of the g-CN-FeO/βCD-Ag nanocomposite were thoroughly characterized using various techniques, including FT-IR, FE-SEM-EDS, TEM, TGA, XRD, ICP, and VSM. This catalytic system exhibited excellent selectivity in reducing nitro groups, even in the presence of other reactive functional groups, resulting in high yields ranging from 85 to 98%.

Spermatogenesis and sperm maturation are complex biological processes that involve intricate cellular and molecular interactions. The Aldh2 gene is involved in the metabolism of specific aldehydes generated by oxidative stress. Aldh2 is abundantly expressed in the testis and epididymis; however, the specific role of Aldh2 in regulating spermatogenesis and sperm maturation remains unclear.

Biomass burning is an important source of brown carbon (BrC) aerosols, which influence climate by affecting the Earth's radiative balance. However, the transformation pathways of BrC chromophores, especially in the presence of photochemically active species, such as nitrate, are not well understood. In this study, the nitrate-mediated aqueous-phase photooxidation of three typical BrC chromophores from biomass burning was investigated, including 4-nitrocatechol, 3-nitrosalicylic acid, and 3,4-dinitrophenol.

Chronic graft-versus-host disease (cGVHD) and oral lichen planus (LPO) are chronic inflammatory conditions with similar oral manifestations. This study aimed to assess whether serum and salivary cytokines (IL-1α, IL-6, IL-17) could serve as reliable biomarkers for cGVHD. A prospective cohort study was conducted involving cGVHD patients, LPO patients, and healthy controls.

Background: Women who had preeclampsia (a history of preeclampsia) have a >4-fold risk of developing cardiovascular disease compared with women who had an uncomplicated pregnancy (history of healthy pregnancy). Despite the remission of clinical symptoms after pregnancy, vascular endothelial dysfunction persists postpartum, mediated in part by exaggerated Ang II (angiotensin II)-mediated constriction. However, the role of vasodilatory ATRs (Ang II type 2 receptors) in this dysfunction is unknown.
