Synthesis and Characterization of N-Coumaroyltyramine as a Potent Phytochemical Which Arrests Human Transformed Cells via Inhibiting Protein Tyrosine Kinases
Abstract
Numerous phytochemicals are believed to have beneficial effects on human health. N-Coumaroyltyramine accumulates in plants in response to wounding and pathogen attack. Due to the scarcity of N-coumaroyltyramine, its biological activities have not been studied in human cells. In this study, N-coumaroyltyramine was chemically synthesized and then purified by an HPLC with a UV-visible absorbance detector. Retention times of major peaks were 14.3 and 20.7 min, and the peak at 20.7 min was confirmed by LC-MS as N-coumaroyltyramine with a mass/charge (m/z) unit of 284.1. The synthesis procedure was relatively easy and had an acceptable yield (approximately 55%). The compound exhibited a new activity, suppression of growth of human tumor cells such as U937 and Jurkat cells. In addition, the suppressed growth of the cells was strongly associated with an increased percentage of cells in the S phase of the cell cycle progression. Furthermore, N-coumaroyltyramine was able to inhibit the protein tyrosine kinases including epidermal growth factor receptor (EGFR). This is the first report of the growth suppressing activity of N-coumaroyltyramine and its arrest of cells at the S phase of the cell cycle, possibly by inhibition of protein tyrosine kinases.

N-trans-coumaroyltyramine at 30 μM decreased living U937 and Jurkat cells by 40% and 32%, respectively, with increasing efficacy at higher concentrations.
“They reported a notable decrease in the number of living cells with 30 μM of N-trans-coumaroyltyramine (40% for U937, 32% for Jurkat), with increasing efficacy at higher concentrations.”
N-trans-coumaroyltyramine dose-dependently inhibits EGFR, with 20% reduction at 30 μM and 75% reduction at 120 μM in U937 cells, and comparable results in Jurkat cells.
“They observed a dose-dependent inhibition of EGFR by N-trans-coumaroyltyramine, with a 20% reduction in activity with 30 μM in the U937 cell line, and a 75% reduction in activity with 120 μM. Comparable results were produced for the Jurkat cell line.”
U937 and Jurkat cells treated with N-trans-coumaroyltyramine, especially at doses higher than 50 μM, halted predominantly in the S phase of the cell cycle.
“Also, they brought attention to the fact that numerous U937 and Jurkat cells treated with the compound, especially at doses higher than 50 μM, halted predominantly in the S phase of the cell cycle.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
