- Design, synthesis, and in vitro antiplatelet aggregation activities of ferulic acid derivatives
-
In order to discover new compounds with antiplatelet aggregation activities, some ferulic acid (FA) derivatives were designed and synthesized. The in vitro antiplatelet aggregation activities of these compounds were assessed by turbidimetric test. The results showed that the target compound 7f had potent antiplatelet aggregation activity with its IC50 27.6 μmol/L, and 7f can be regarded as a novel potent antiplatelet aggregation candidate.

- Design, synthesis, and preliminary evaluation of substituted cinnamic acid esters as selective matrix metalloproteinase inhibitors
-
Strategy, Management and Health Policy Preclinical Research Substituted cinnamic acid esters with extended P1' groups were synthesized using microwave irradiation and tested for their inhibitory activities on matrix metalloproteinase (MMP)-1, MMP-2, and MMP-9. Preliminary structure-activity relationship analysis and docking studies showed that hydroxyl groups in the benzene ring and the presence of extended spatial structures in the carboxylic acid played key roles in the MMP-2 and MMP-9 inhibitory activity and selectivity over MMP-1.

- Highly efficient esterification of ferulic acid under microwave irradiation
-
A highly efficient synthesis of alkyl ferulates under microwave irradiation is described. The time of these reactions ranged from 3 to 5 minutes, which was much shorter than the traditional synthetic methods, and the alkyl ferulates were obtained in higher yields.

- Impact of alkyl esters of caffeic and ferulic acids on tumor cell proliferation, cyclooxygenase enzyme, and lipid peroxidation
-
The antioxidant ferulic and caffeic acid phenolics are ubiquitous in plants and abundant in fruits and vegetables. We have synthesized a series of ferulic and caffeic acid esters and tested for tumor cell proliferation, cyclooxygenase enzymes (COX-1 and -2) and lipid peroxidation inhibitory activities in vitro. In the tumor cell proliferation assay, some of these esters showed excellent growth inhibition of colon cancer cells. Among the phenolics esters assayed, compounds 10 (C12-caffeate), 11 (C16-caffeate), 21 (C 8-ferulate), and 23 (C12-ferulate) showed strong growth inhibition with IC50 values of 16.55, 13.46, 18.67, and 7.57 μg/mL in a breast cancer cell line; 9.65, 7.45, 17.05, and 4.35 μg/ mL in a lung cancer cell line; 5.78, 3.5, 4.29, and 2.46 μg/mL in a colon cancer cell line; 12.04, 12.21, 14.63, and 8.09 μg/ mL in a central nervous system cancer cell line; and 8.62, 7.76, 11.0, and 5.37 in a gastric cancer cell line. In COX enzyme inhibitory assays, ferulic and caffeic acid esters significantly inhibited both COX-1 and COX-2 enzymes. Caffeates 5-10 (C4-C 12), inhibited COX-1 enzyme between 50% and 90% and COX-2 enzyme by about 70%, whereas ferulates 15-21 (C3-C8) inhibited COX-1 and COX-2 enzymes by 85-95% 25 μg/mL. Long-chain caffeates 11-14 (C 16-C22) and short-chain ferulates 15-20 (C 3-C5) were the most active in lipid peroxidation inhibition and showed 60-70% activity at 5 μg/mL concentration.

- Mapping the hydrolytic and synthetic selectivity of a type C feruloyl esterase (StFaeC) from Sporotrichum thermophile using alkyl ferulates
-
The active site of Sporotrichum thermophile type C feruloyl esterase (StFaeC) was probed using a series of C1-C4 alkyl ferulates. The affinities for straight and branched alkyl ferulates were demonstrated by the Km values of 1.64-0.51 and 0.19-0.1, respectively. Comparison of kcat and kcat/Km values shows that the enzyme hydrolyzed n-propyl ferulate faster and iso-propyl ferulate more efficiently. Alkyl ferulates were applied also for substrate selectivity mapping of feruloyl esterase to catalyze feruloyl group transfer to l-arabinose, using as a reaction system a ternary water-organic mixture consisting of n-hexane, t-butanol and water. Lengthening the aliphatic side chain was the most significant factor causing lower synthetic activity of the enzyme. The reaction parameters affecting the feruloylation rate and the conversion of the enzymatic process, such as the temperature and substrate concentration have been investigated. Under identical reaction conditions, the enzyme feruloylated other monosaccharides such as d-arabinose, d-glucose, d-xylose, d-mannose, d-fructose, d-galactose, d-ribose and model substrates such as 4-nitrophenyl α-l-arabinofuranoside and 4-nitrophenyl α-l-arabinopyranoside.
