Abstract:
Six compounds were isolated from the MeOH extract of the whole bodies of Munronia henryi. Their structures were elucidated as sitosterol-3-O-12',13'-epoxy-9'-oxo-(10'E)-octadecenoate (1), alpha-D-glucopyranosyl-6'-O-hexadecanoate (2), 4alpha,7alpha-aromodendranediol (3), 2beta,3beta,4beta-trihydroxypregnan-16-one (4), 4-O-alpha-D-psicofuranos-alpha-D-glucopyranose (5), and glyceryl-1-tetracosanoicate (6) on the basis of spectroscopic methods. Among them 1 was a new sterol carrying an octadecenoyl; 2 and 6 were isolated for the first time from a natural source.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...
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.
