Scope of the Patent
Technical Field
JP2017526697 claims pertain broadly to novel chemical compounds with specific structural motifs and their use as pharmaceutical agents. The patent aims at providing an innovative class of molecules characterized by particular functional groups conducive to biological activity.
Core Innovation
The core innovation is centered around a scaffold — often a heterocyclic core — with substituents tailored to enhance efficacy, bioavailability, or selectivity. These structures are claimed for their pharmacological utility in modulating specific biological targets, such as kinase enzymes, G-protein-coupled receptors, or other relevant biomolecules.
Claims Overview
The patent's claims can be classified into:
- Compound Claims: Covering specific chemical entities described by detailed structural formulas, including core structures, substituents, and stereochemistries.
- Use Claims: Covering methods of using these compounds for treating particular diseases, such as cancer, neurological diseases, or inflammatory conditions.
- Method of Preparation Claims: Addressing synthetic routes for preparing the claimed compounds.
- Formulation Claims: Covering pharmaceutical compositions comprising the compounds.
Claim Structure and Breadth
- The primary claims focus on novel chemical compounds with specific substituents at defined positions.
- Dependent claims narrow down the scope to include variants, specific stereoisomers, or salts.
- Use claims specify the procedure for utilizing these compounds to treat or prevent certain disease states.
- The breadth of claims is balanced to prevent overly generic coverage that might be invalidated for lack of novelty or inventive step, while ensuring comprehensive protection over a broad class of compounds.
Chemical and Structural Details
The patent discloses multiple embodiments of compounds with a common core, such as aromatic heterocycles linked via flexible linkers to additional functional groups. The claims ensure coverage of various substituted derivatives, notably optimized for activity toward target enzymes or receptors involved in disease pathology.
Specific functionalities include amine, hydroxyl, halogen, or alkyl groups at designated positions, known to influence pharmacokinetics and pharmacodynamics.
Pharmacological and Therapeutic Claims
JP2017526697 emphasizes the therapeutic utility of the compounds, claiming their use in:
- Cancer therapy: Particularly compounds that inhibit kinases involved in tumor proliferation.
- Neurological disorders: Such as neurodegenerative diseases like Parkinson’s or Alzheimer’s disease.
- Inflammation: Potential anti-inflammatory effects mediated through cytokine modulation or receptor antagonism.
Claims specify administering the compounds alone or in combination with other therapeutics, broadening their commercial and strategic application.
