Abstract:
To search for active anti-cancer constituents in the fruiting body of Ganoderma calidophilum, we have successfully isolated four previously undescribed spiro-lactone lanostane triterpenoids (spiroganocalitones A-D), two previously undescribed lanostanoids (ganodecalones A and B) together with twenty-three known ones. The structures of the six previously undescribed compounds were elucidated based on 1D, 2D-NMR, and HRMS analyses. Ganoderone A showed moderate cytotoxic activity against K562, BEL7402, and SGC790 cell lines with IC50 values of 7.62, 6.28, and 3.55 μM, respectively.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
