3,4,5-Trimethoxycinnamic acid (TMCA), methyl 3,4,5-trimethoxycinnamate (M-TMCA) and p-methoxycinnamic acid (PMCA) have been identified as the major bioactive components in the serum collected from rats treated with oral administration of Polygalae Radix ("YuanZhi," the roots of Polygala tenuifolia WILLD.), a traditional
We report here the isolation and characterization of two active principles, ethyl 3',4',5'-trimethoxycinnamate (1) and piperine (2), from the combined hexane and chloroform extracts of Piper longum. Using primary human umbilical vein endothelial cells, we evaluated the activities of compound
3,4,5-trimethoxycinnamic acid (TMCA) is one of the constituents in Onji (roots of Polygala tenuifolia WILLD), an herbal medicine used for sedative in Japanese traditional Kampo medicine. Our previous study revealed that oral administration of this compound prolongs sleeping time induced

When grown on 3,4,5-trimethoxycinnamic acid, a strain of Pseudomonas putida oxidized this compound and also 3,4,5-trimethoxybenzoic, 3,5-dimethoxy-4-hydroxybenzoic (syringic), and 3,4-dihydroxy-5-methoxybenzoic (3-O-methylgallic) acids, but 3,5-dimethoxy-4-hydroxycinnamic and other acids bearing structural resemblances to the growth substrate were oxidized only slowly. These results
A highly flexible and concise total synthesis of (+)-podophyllotoxin featured with an enantioselective sequential conjugate addition-allylation reaction was reported. Starting from commercially available 3,4,5-trimethoxycinnamic acid, this new route leads to (+)-podophyllotoxin 1 in only eight steps with 29% overall yield.
