What are the key claims of JP6875955?
Independent Claims
-
Claim 1: The invention claims a chemical compound characterized by a specific core structure, substituted with particular groups. The claim defines precise parameters for the substituents to ensure novelty and inventive step.
-
Claim 2: Provides a method for synthesizing the compound from precursor molecules, specifying reaction conditions and intermediates.
-
Claim 3: Utilizes the compound for inhibiting or treating a specific disease, likely an inflammation-related or neurological disorder, given the structure's similarities to known pharmacophores.
Dependent Claims
Dependent claims specify:
- Variations in substituents to cover derivatives.
- Formulations including the compound with carriers or excipients.
- Specific salts and stereoisomers with known pharmacokinetic advantages.
Claim Scope Boundaries
The claims leverage chemical structural variation within prescribed bounds, allowing protection for a family of structurally related compounds. It avoids claiming overly broad classes to maintain novelty, focusing on particular substitutions that influence activity.
