The effect of the fused-ring substituent on anthracene chalcones: crystal structural and DFT studies of 1-(anthracen-9-yl)-3-(naphthalen-2-yl)prop-2-en-1-one and 1-(anthracen-9-yl)-3-(pyren-1-yl)prop-2-en-1-one

Acta Crystallographica Section E: Crystallographic Communications, 2018
The title chalcone compounds, C27H18O (I) and C33H20O (II), were synthesized using a Claisen–Schmidt condensation. Both compounds display an s-trans configuration of the enone moiety.

Role of SIRT1-HMGB1-NLRP3 inflammasome axis in the protective effects of trans-chalcone on myocardial ischemia and reperfusion injury

General physiology and biophysics
Myocardial ischemia and reperfusion (MIR) injury, a major cause of cardiovascular morbidity, involves oxidative stress, inflammation, and cell death. This study examines the protective effects of trans-chalcone, a natural flavonoid, on MIR-induced myocardial damage via the Sirtuin 1 (SIRT1)-High Mobility Group Box 1 (HMGB1)-inflammasome-pyroptosis axis.
