Electron Paramagnetic Resonance Study of the Radiation Damage in Trans-Chalcone Single Crystal

Acta Physica Polonica A, 2019
Gamma irradiated trans-chalcone (C15H12O) single crystals are investigated at 120 K using electron paramagnetic resonance technique. Trans-chalcone single crystals are irradiated with Co-60-gamma rays, at room temperature. The EPR spectra of gamma irradiated trans-chalcone single crystals are studied for different orientations of crystals in a magnetic

The solubility and stability of heterocyclic chalcones compared with trans-chalcone [PDF]

Acta Crystallographica Section B Structural Science, Crystal Engineering and Materials, 2020
Heterocyclic chalcones are a recently explored subgroup of chalcones that have sparked interest due to their significant antibacterial and antifungal capabilities. Herein, the structure and solubility of two such compounds, (E)-1-(1H-pyrrol-2-yl)-3-(thiophen-2-yl)prop-2-en-1-one and (E)-3-phenyl-1-(1H-pyrrol-2-yl)prop-2-en-1-one, are assessed.

trans-Chalcone protects male rats against high-fat emulsion-induced pancreatic injury by inhibiting TNF-α and MCP-1 expression [PDF]

مجله پزشکی دانشگاه علوم پزشکی تبریز, 2023
Background. High-fat diet (HFD) intake is linked to ectopic fat deposition in the pancreas. It also causes pancreatic inflammatory lesions. trans-Chalcone is a simple chalcone with protective effects against HFD-induced metabolic disorders.

A simple and rapid spectrophotometric method for the determination of trans-chalcone in raw-material and topical formulation

Semina: Ciências Biológicas e da Saúde, 2023
Trans-chalcone (TC) is a flavonoid precursor characterized by a wide spectrum of action, with anti-inflammatory and antioxidant effects. However, no validated methods are available in official compendia for the analysis of this substance. Thus, the aim of this work was to develop and validate a simple, fast, and reproducible spectrophotometric method ...
