Abstract
The aim of the study was to assess the effect of certain derivatives of cinnamic acids on changes of the tricarboxylic acid cycle enzymes activity under experimental cerebral ischemia.
Materials and methods. Brain ischemia was modeled by irreversible right-sided coagulation of the middle cerebral artery. Test compounds: 4-hydroxy-3,5-ditretbutyl cinnamic acid, coumaric, coffee, synapic, cinnamic, 4-hydroxycinnamic and ferulic acids, as well as a reference drug — succinic acid was administered at a dose of 100 mg / kg per os for 3 days after the reproduction of ischemia. Then, changes in the activity of aconitase, citrate synthase, and α-ketoglutarate dehydrogenase were evaluated in the supernatant of the brain.
Results. The use of all the studied compounds and the reference drug helped to restore the activity of enzymes of the tricarboxylic acid cycle. The most pronounced results were obtained when animals were treated by 4-hydroxy-3,5-ditretbutyl cinnamic acid, against the background of which the activity of citrate synthase was higher than in animals treated by succinic, coumaric, coffee, synapic and ferulic acids by 1.53 (p < 0.05), 1.41 (p < 0.05), 1.4 (p < 0.05), 1.46 (p < 0.05) and 1.41 (p < 0.05) times, respectively. Also, with the administration of 4-hydroxy-3,5-ditretbutyl cinnamic acid, the activity of aconitase was higher compared to rats that were administered with succinic, coumaric, coffee, synapic and ferulic acids by 2.47 (p < 0.05), 2.49 (p < 0.05), 3.44 (p < 0.05), 2.59 (p < 0.05) and 1.9 (p < 0.05) times, respectively.
Conclusion. The administration of the studied in this work cinnamic acid derivatives helps to restore the activity of citrate synthase, aconitase, and α-ketoglutarate dehydrogenase in rats under conditions of cerebral ischemia. The most pronounced changes in the activity of enzymes were obtained with the iadministration of 4-hydroxy-3,5-ditretbutyl cinnamic acid.
