Scope of the Patent: Key Aspects
What is the invention?
The patent discloses a class of heterocyclic compounds with potential use as therapeutic agents, particularly targeting neurodegenerative diseases (e.g., Alzheimer’s), metabolic disorders, and other chronic conditions.
Core chemical scope
The patent claims a broad genus of molecules characterized by:
- A heterocyclic core (e.g., pyrazoline, pyrrolidine)
- Substituents at specific positions allowing variation
- Functional groups enhancing pharmacokinetics and target affinity
Example chemical structure (excerpt from the patent):
- A core heterocycle with substitutions at positions R1, R2, R3, each capable of diverse groups (alkyl, aryl, heteroaryl)
- Variants with differing side chains to optimize activity
