Efeito da substituição por átomos de flúor no equilíbrio conformacional de chalcona

Química Nova, 2001
Chalcone (1) and its fluorinated derivatives 2-4, as well as their cyclic analogues 5-10, were synthesized through an aldol condensation reaction between the corresponding ketone and aldehyde. These compounds were characterized by IR, EIMS and ¹H and 13C

Developmentally and transgene regulated nuclear processing of primary transcripts of chalcone synthase A in petunia

, 2000
The introduction of chalcone synthase A transgenes into petunia plants can result in degradation of chalcone synthase A RNAs and loss of chalcone synthase, a process called cosuppression or post-transcriptional gene silencing.

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.
