Abstract:
Four structurally unprecedented tricyclic depsi-tripeptides, ohauamines A-D (1-4), were isolated from the New Zealand endemic ascidian Pycnoclavella kottae. Planar structures were elucidated by extensive use of 1H-, 13C-, and 15N-based NMR experiments, with absolute configurations established by computational methods.

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.
