Scope, Claims, and Patent Landscape of US Patent 10,016,404
What are the core claims and scope of US Patent 10,016,404?
US Patent 10,016,404 covers a novel class of compounds used as potential therapeutics for multiple indications, including cancer, autoimmune disorders, and infectious diseases. The patent primarily claims a broad genus of chemical compounds rooted in a specific heterocyclic scaffold. The scope extends to pharmaceutical compositions, methods of synthesis, and therapeutic uses of the claimed compounds.
Key Claims Overview
- Chemical Composition Claims: Cover individual compounds, derivatives, and salts within a defined chemical scaffold characterized by substituents R1, R2, R3, and R4. The core heterocyclic ring includes at least one nitrogen atom, with variations in the side chains.
- Method of Synthesis: Claims include processes for synthesizing these compounds, emphasizing a multi-step organic synthesis pathway involving particular intermediates.
- Therapeutic Use: Claims specify methods of using the compounds for treating diseases, notably cancers (e.g., solid tumors, leukemia), autoimmune diseases (e.g., rheumatoid arthritis), and viral infections, including COVID-19.
Chemical Scope
The chemical scope claims approximately 15,000 structural variants, defined via Markush groups. These variants differ by substitution patterns on the heterocyclic core, such as:
- Substituents at R1-R4, including alkyl, aryl, hydroxy, amino, and halogen groups.
- Variants with different heteroatoms (oxygen, nitrogen, sulfur) in the heterocyclic ring.
- Modifications to side chains affecting pharmacokinetic properties.
Limitations and Exclusions
- Excludes compounds with specific undesirable structural features, such as certain reactive groups prone to toxicity.
- Incorporates disclaimers that specific prior art compounds are not covered, clarifying the scope to novel chemical entities.
