Analysis of Claims
1. Independent Claims
The core claims of the patent are structured as follows:
Claim 1: A bifunctional molecule comprising:
- a ligand component capable of binding to T-cell surface receptors;
- an anti-inflammatory component linked via a cleavable linker;
- wherein the compound exhibits increased selectivity towards pathogenic T-cells implicated in autoimmune response.
Claim 2: The bifunctional molecule of claim 1, wherein the ligand component is a PeptideX sequence (SEQ ID NO: 1).
Claim 3: The anti-inflammatory component is a cytokine-inhibiting antibody fragment (e.g., anti-IL-6 receptor Fab).
The claims establish novelty by combining specific ligand and antibody fragment constructs into a single molecule for targeted immunomodulation.
2. Dependent Claims
Dependent claims specify particular embodiments, including:
- Chemical modifications enhancing stability (Claim 4).
- Specific linker chemistries (e.g., PEGylated linkers—Claim 5).
- Dosage regimens and administration routes (Claims 6-8).
