Three new compounds, boesenmaxanes A-C, were isolated from Boesenbergia maxwellii. Boesenmaxanes A and C demonstrated significant anti-HIV activity, highlighting their potential therapeutic value.
Area of Science:
- Natural Products Chemistry
- Medicinal Chemistry
- Organic Chemistry
Background:
- Boesenbergia maxwellii rhizomes are a source of bioactive compounds.
- Diterpenoids with unique skeletons are of interest for drug discovery.
Purpose of the Study:
- To isolate and characterize new diterpenoids from Boesenbergia maxwellii.
- To evaluate the biological activities of these novel compounds.
Main Methods:
- Isolation and purification of compounds using chromatographic techniques.
- Structure elucidation via spectroscopic methods (NMR, MS) and X-ray diffraction.
- Determination of absolute configuration using Electronic Circular Dichroism (ECD) spectroscopy.
Main Results:
- Three new diterpenoids, boesenmaxanes A-C (1-3), featuring a novel C-C bond between C-12 and an exocyclic methylene C-13, were identified.
- Boesenmaxanes A and C exhibited significant inhibitory activity against HIV in the syncytium reduction assay.
- EC50 values for boesenmaxanes A and C were determined to be 55.2 μM and 27.5 μM, respectively.
Conclusions:
- Boesenbergia maxwellii yields structurally unique diterpenoids.
- Boesenmaxanes A and C possess notable anti-HIV properties, warranting further investigation.

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.
