Thienopyrimidinone Compounds Modulate Protein Homeostasis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for inflammatory and autoimmune diseases, such as rheumatoid arthritis and cancer, face challenges due to the short half-life of cytokines like IL-2, leading to high doses and systemic side effects, and the need for localized delivery methods to minimize these issues and enhance therapeutic efficacy.
Innovation Solution
Development of compounds that modulate protein function and levels by targeting specific proteins involved in disease pathways, such as GSPT1, cytokines, and other proteins like Aiolos and CK1α, using ubiquitin-mediated proteolysis to regulate protein activity and expression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high doses of cytokines like IL-2 are administered to overcome short half-life, then therapeutic efficacy is improved, but systemic side effects increase
Solution Approach 1:
The invention segments the therapeutic approach by using localized delivery systems (such as localized expression vectors, implantable devices, or targeted nanoparticles) to deliver cytokines specifically to the tumor site or affected tissue. This segmentation allows the cytokine therapy to be divided into localized action (at the target site) and minimized systemic exposure, thereby maintaining efficacy while reducing side effects
Solution Approach 2:
The invention applies local quality by creating high concentrations of cytokines specifically at the disease site through localized delivery mechanisms. This ensures that the therapeutic effect is concentrated where needed (improving productivity/efficacy) while the rest of the body receives minimal exposure (reducing harmful factors/side effects)
2Quantity of substance
If cytokines are administered systemically to ensure adequate therapeutic levels, then therapeutic coverage is improved, but half-life limitations require frequent dosing
Solution Approach 1:
The invention employs preliminary action through localized pre-conditioning of the target tissue or tumor microenvironment before cytokine delivery. This may involve delivering vectors that express cytokines locally, implanting devices that provide sustained release, or preparing the target site to enhance cytokine retention and activity, thereby extending the effective duration and reducing dosing frequency
Solution Approach 2:
The invention achieves continuity of useful action through localized sustained-release delivery systems (such as implantable pumps, erodible matrices, or continuously expressing genetic vectors) that maintain therapeutic cytokine levels at the target site over extended periods. This continuous localized action ensures adequate therapeutic coverage while minimizing the need for frequent systemic dosing
