Abstract:
Four new phenanthrenoid dimers, effususins A-D (1-4), were isolated from an ethanolic extract of the medullae of Juncus effuses (Juncaceae). Their structures were elucidated by 1D and 2D NMR spectroscopic analysis and mass spectrometry. Compounds 1-4 was in vitro evaluated for their cytotoxic activities by CCK-8 assay against five human cancer cell lines (SHSY-5Y, SMMC-7721, HepG2, Hela, and MCF-7) and their inhibitory effects on NO production in lipopolysaccharide-activated murine macrophage RAW264.7 cells. Effususin B exhibited moderate to strong cytotoxic activities against the tested cancer cell lines and moderate anti-inflammatory activity.

Antiasthma Drugs: Methylxanthines
Theophylline is thought to inhibit phosphodiesterase enzymes, increasing intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). This rise in cAMP and cGMP concentrations stimulates cardiac function,...

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.
