AI Article Synopsis

  • The insertion of double and triple bonds into the C-Cl bond of carbon tetrachloride enhances its usefulness in chemical synthesis.
  • A variety of unactivated imines and nitrogen heteroarenes are utilized to create C=N bonds that react with arynes and carbon tetrachloride, leading to the formation of functionalized anilines important for certain arthropodicides.
  • Control experiments and DFT calculations indicate that a trichloromethyl anion intermediate plays a critical role in this reaction process.

Article Abstract

The formal insertion of double and triple bonds into the C-Cl bond of carbon tetrachloride has enabled the full utilization of carbon tetrachloride in chemical synthesis. A range of unactivated imines and electron-deficient nitrogen heteroarenes served as effective sources of C=N bonds to react with arynes and carbon tetrachloride to afford functionalized anilines whose core structures are present in some valuable arthropodicides. Control experiments and DFT calculations suggest the involvement of a trichloromethyl anion intermediate.

Background Photoacoustic microscopy (PAM) can be used to detect strong absorption from endogenous and exogenous contrast material, making it promising for detailed structural and functional imaging of hepatic sinusoids, including dynamic visualization of permeability. Purpose To evaluate whether PAM-based quantitative parameters of liver function and integrity (lacunarity, blood oxygen saturation [Sao], and Evans blue [EB] permeability) are associated with histopathologic indexes of fibrosis in a mouse model. Materials and Methods Between October 2022 and July 2023, a total of 35 male C57BL/6 mice were included in this study and received intraperitoneal injection of carbon tetrachloride to establish mouse models of progressive liver fibrosis, with seven mice in each group.

The activation of hepatic stellate cells (HSCs) from a quiescent state is a cause of liver fibrosis and a therapeutic target. HSCs are resident mesenchymal cells located in the space of Disse, exhibiting specialized morphological characteristics such as a stellate shape, large lipid droplets, and direct adhesions to hepatocytes via microprojections called HSC spines. Morphological alterations in HSCs play a crucial role in initiating their activation.

The genus (Lamiaceae family) comprises approximately 300 species, which are widely used in traditional medicine for their diaphoretic, antiseptic, hemostatic, and anti-inflammatory properties, but scarcely in official ones. Therefore, the study of holds promise for developing new medicinal products. In aqueous and aqueous-alcoholic soft extracts of the herb, 16 amino acids, 20 phenolics, and 10 volatile substances were identified by HPLC and GC/MS.

Background: For the treatment of liver fibrosis, several novel cell therapies have been proposed. Autologous macrophage therapy has been reported as one of the promising treatments. So far, most studies have used colony-stimulating factor 1 (CSF-1) to induce the differentiation of macrophage progenitor cells.

The human body gets exposed to a variety of toxins intentionally or unintentionally on a regular basis from sources such as air, water, food, and soil. Certain toxins can be synthetic, while some are biological. The toxins affect the various parts of the body by activating numerous pro-inflammatory markers, like oxidative stresses, that tend to disturb the normal function of the organs ultimately.
