Chemical Scope
The core chemical scope hinges on a general formula, with variable substituents. Table 1 summarizes the core structural features:
| Structural Core |
Substituent Variations |
Examples |
Implications |
| Main scaffold (e.g., heterocyclic ring) |
R1, R2, R3, R4, R5 variables |
Aromatic or heteroaryl groups |
Large generational scope for compound diversity |
| Linkers & functional groups |
Alkyl, alkoxy, amino, etc. |
Alkyl chains, hydroxyl groups |
Variable pharmacokinetic and pharmacodynamic profiles |
Source: Patent Specification [WO2008075207]
The scope encompasses hundreds of potential compounds due to combinatorial variability around the core structure.
Method of Synthesis
Claims extend to chemical synthesis pathways that facilitate:
- Stepwise reactions.
- Specific reagents and solvents.
- Conditions enabling the formation of the claimed compounds.
Therapeutic Method Claims
The patent broadly claims the use of these compounds in:
- Treating inflammatory diseases.
- Oncology (cancer)
- Metabolic disorders (e.g., diabetes)
- Other diseases modulating targeted pathways.
Legal and Geographic Scope
- The application designates multiple jurisdictions through subsequent national phase applications.
- The scope is thus potentially enforceable in key markets: U.S., EU, China, Japan, etc., depending on patent validation.

Representative Claim Analysis
-
Claim 1 (Compound Claim):
"A compound represented by structural formula I, wherein R1, R2, R3, R4, and R5 are as defined, and the compound exhibits activity against [target pathway/disease]."
-
Claim 2 (Method of Synthesis):
"A method for synthesizing compound of claim 1 involving stepwise reactions with reagents A, B, and C under specific conditions."
-
Claim 10 (Use in Treatment):
"The use of compound of claim 1 in a method for treating inflammatory diseases."
Note: The breadth of the compound claims suggests a focus on both specific molecules and a chemical genus, which has critical implications for potential patent enforcement and licensing.
