    Inhibitory effect of trans-N-p-coumaroyl tryamine from the twigs of Celtis chinensis on the acetylcholinesterase.[Pubmed: 14560923]

    METHODS AND RESULTS:
    The methanolic extract of the twigs of Celtis chinensis was found to show inhibitory activity on acetylcholinesterase (AChE), an enzyme that plays a role in the metabolic hydrolysis of ACh. Bioassay-guided fractionation of the methanolic extract resulted in the isolation of N-p-trans-Coumaroyltyramine, as an inhibitor on AChE.
    CONCLUSIONS:
    This compound inhibited AChE activity in a dose-dependent manner, and the IC50 value of N-p-trans-Coumaroyltyramine was 34.5 microg/mL (122 microM).

    Cinnamoylphenethyl amides from Polygonum hyrcanicum possess anti-trypanosomal activity.[Pubmed: 22816300]

    METHODS AND RESULTS:
    A methanolic extract from aerial parts of Polygonum hyrcanicum (Polygonaceae) showed high activity against Trypanosoma brucei rhodesiense (IC50 = 3.7 microg/mL). Bioassay-guided fractionation of the extract resulted in isolation of cinnamoylphenethyl amides, including N-trans-caffeoyltyramine (1), N-p-trans-Coumaroyltyramine (7), and N-trans-feruloyltyramine (8) as the main active constituents (IC50s ranging from 2.2 to 13.3 microM). Some structurally related, but less active compounds, such as cannabisin B (2), tyrosol (3), p-coumaric acid (4), ferulic acid (5), and N-cis-feruloyltyramine (6) were also identified, along with N-trans-3,4-dimethoxycinnamoyldopamine (9).
    CONCLUSIONS:
    Cytotoxicity of the active compounds in L6 cells was determined, and selectivity indices (SI) of 7.9 to 33.4 were calculated.

    Isolation and Activity of N-p-Coumaroyltyramine, an α-Glucosidase Inhibitor in Welsh Onion (Allium fistulosum)[Reference: WebLink]
    A phenolic amide, N-p-trans-Coumaroyltyramine(1), was isolated as an α-glucosidase inhibitor from methanol extracts of Welsh onion (Allium fistulosum). The inhibitory activity of 1 against a yeast enzyme was as high as Ki 8.4 × 10617 m. From a structure-activity relationship study of 1 and its related compounds, the occurrence of α-glucosidase inhibitory activity required a p-coumaramide structure, with an amide hydrogen and alkyl or aralkyl substituent on the amide part.

    Interaction Studies of Coumaroyltyramine with Human Serum Albumin and Its Biological Importance[Pubmed: 20136105]
    N-trans-p-coumaroyltyramine (N-p-trans-Coumaroyltyramine, CT) isolated from Physalis minima is a phenolic substance exhibiting many pharmacological activities like potent inhibition of acetyl cholinesterase, cell proliferation, platelet aggregation, and also antioxidant activity.
    METHODS AND RESULTS:
    Here, we have studied the binding of CT with HSA at physiological pH 7.2 by using fluorescence, circular dichroism spectroscopy, mass spectrometry, and molecular docking methods. From the fluorescence emission studies, the number of binding sites and binding constant were calculated to be 2 and (4.5 +/- 0.01) x 10(5) M(-1), respectively. The free energy change was calculated as -7.6 kcal M(-1) at 25 degrees C, which indicates the hydrophobic interactions of CT with HSA and is in well agreement with the computational calculations and molecular docking studies. The changes in the secondary structure of HSA after its complexation with the ligand were studied with CD spectroscopy, which indicated that the protein became partially unfolded. Also, temperature did not affect the HSA-CT complexes.
    CONCLUSIONS:
    The binding of CT with HSA was detected as 2 molecules bound to HSA was determined using micro TOF-Q mass spectrometry. Further, molecular docking studies revealed that CT was binding at subdomain IIA with hydrophobic interactions and also by hydrogen-bond interactions between the hydroxyl (OH) group of carbon-16 and carbon-2 of CT and Arg222, Ala291, Val293, and Met298 of HSA, with hydrogen-bond distances of 2.488, 2.811, 2.678, and 2.586 A, respectively.
