ABSTRACT
Ferulic acid (FA) is a polyphenolic compound with demonstrated antioxidant capacity. In this study, propionylferulate (PF) was synthesized and characterized using melting point, ultraviolet spectroscopy, Fourier-transforminfrared spectroscopy, and mass spectrometry. The propionyl ferulate was comparatively evaluated for antioxidantpotential which included the ability to quench reactive species of 2,2-diphenyl-2-picrazyl-hydrazyl (DPPH), hydroxyl,nitric oxide, and superoxide anion. In addition, the total antioxidant capacity and membrane stabilizing properties ofthe ferulate were determined. Comparatively, the spectroscopically characterized PF showed superior scavengingcapacity for the DPPH, hydroxyl, and nitric oxide free radicals when compared to FA. On the contrary, PF showed apoor scavenging capacity for superoxide anion radicals. Furthermore, PF showed little or no potential for membranestability. In conclusion, the data suggest that structurally modifying FA to PF improved the antioxidant capacity forseveral free radicals.
ABSTRACT
Objective: To evaluate the antipiroplasmic activities of methanolic extract of Olea europaea (MOE) and acetonic extract of Acacia laeta (AAL) against Babesia and Theileria parasites in vitro and evaluate the chemotherapeutic effects of these extracts against Babesia (B.) microti in vivo. Methods: Fluorescence assay using SYBR Green 1 nucleic acid stain was used to detect inhibitory effects of the two extracts as well as the combination effects of the two extracts with diminazene aceturate and atovaquone on four Babesia species and Theileria equi in vitro while for in vivo experiments, 8-weekold female BALB/c mice were injected intraperitoneally with 1 × 10
