Structural Diversity and Bioactivity
Natural compounds are classified by their chemical skeletons, which dictate their biological activity. Key classes taught at Sechenov include:
- Flavonoids: Known for antioxidant properties (e.g., quercetin in apples).
- Triterpenoids: Anti-inflammatory agents (e.g., oleanolic acid in olives).
- Alkaloids: Neuroactive compounds (e.g., morphine from poppies).
These structures are explored through spectral analysis (UV, NMR) and computational modeling to predict interactions with biological targets .
Extraction and Separation Techniques
Students master methods to isolate bioactive molecules:
Solvent extraction: Using polarity gradients to separate compounds.
Chromatography: HPLC and TLC for purifying complex mixtures.
Distillation: Essential for volatile oils like eucalyptus terpenes.
A cornerstone of the curriculum is linking these techniques to clinical outcomes—for instance, optimizing yields of cardiac glycosides for heart disease treatments .
