Abstract:
Three new compounds (1-3), including two bisamide derivatives (1 and 2) and a lignin (3), along with 15 known compounds were isolated from Aglaia odorata. Compound 2 was a pair of enantiomers and successfully resolved into the anticipated enantiomers. Their structures were elucidated by extensive spectroscopic analysis, electronic circular dichroism (ECD) calculations, and X-ray crystallography. Three compounds showed excellent inhibitory activities on α-glucosidase with IC50 values ranging from 54.48 to 240.88 μM, better than that of the positive control (acarbose, IC50 = 590.94 μM). Moreover, compounds 3, 13, and 15 presented moderate inhibitory activities against butyrylcholinesterase. Compound 17 exhibited potent PTP1B inhibitory activity with an IC50 value of 179.45 μM. Representative active compounds were performed for the molecular docking study. Herein, we described the isolation, structure elucidation, the inhibitory effects on three enzymes, and molecular docking of the isolates from the title plant.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
