RESUMEN
Fractionation of the EtOH extract from aerial parts of Baccharis uncinella C. DC. (Asteraceae) led to isolation of caffeic and ferulic acids, which were identified from spectroscopic and spectrometric evidence. These compounds exhibit antioxidant and anti-inflammatory properties and have been shown to be effective in the prevention/treatment of metabolic syndrome. This study investigated whether the combined treatment of caffeic and ferulic acids exhibits a more significant beneficial effect in a mouse model with metabolic syndrome. The combination treatment with caffeic and ferulic acids was tested for 60 days in C57 mice kept on a high-fat (40%) diet. The data obtained indicated that treatment with caffeic and ferulic acids prevented gain in body weight induced by the high-fat diet and improved hyperglycemia, hypercholesterolemia and hypertriglyceridemia. The expression of a number of metabolically relevant genes was affected in the liver of these animals, showing that caffeic and ferulic acid treatment results in increased cholesterol uptake and reduced hepatic triglyceride synthesis in the liver, which is a likely explanation for the prevention of hepatic steatosis. In conclusion, the combined treatment of caffeic and ferulic acids displayed major positive effects towards prevention of multiple aspects of the metabolic syndrome and liver steatosis in an obese mouse model.

FtsZ plays an important role in bacterial cell division by polymerizing to form the Z ring at the site of cytokinesis. Phytochemicals are known to disrupt bacterial cell division through inhibition of FtsZ assembly. In the present study phytochemicals like eugenol, trans-cinnamic acid, 4-formyl cinnamic acid, naringenin and caffeic acid were were tested for their potential to inhibit cell division. Effect of these antimicrobial compounds on the growth of E. coli was determined and the inhibition of FtsZ assembly in vitro was investigated. The present study revealed trans-cinnamic acid as the most potent inhibitor of FtsZ assembly.
