Ascaroside Derivatives for Precise Autoimmune Immune Modulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for autoimmune and inflammatory diseases using nematode-derived factors are inadequate, necessitating improved therapeutic options that modulate immune responses effectively.
Innovation Solution
Development of ascaroside derivatives, specifically compounds of Formula (I) and (II), which inhibit IL-6 and IL-1β secretion, reducing the hallmark pathologies in mouse models of asthma, inflammatory bowel disease, and type 1 diabetes, and are administered to subjects to treat inflammatory and autoimmune disorders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parasitic nematodes or nematode derived secretions are administered to treat autoimmune diseases, then disease symptoms are alleviated, but treatment efficacy and safety are insufficient
Solution Approach 1:
The patent extracts and isolates specific bioactive compounds (ascarosides) from parasitic nematodes. Instead of administering whole nematodes or complex secretions, the invention identifies and purifies specific molecular entities (Formula I compounds) that mediate the therapeutic effect, thereby simplifying the treatment while maintaining or enhancing efficacy.
Solution Approach 2:
The patent modifies the chemical structure of natural ascaroside compounds by creating derivatives with specific structural variations (different Ring D configurations, substituent patterns, and stereochemistry). These parameter changes in molecular structure aim to optimize pharmacological properties including potency, selectivity, and safety profile compared to natural products.
2Adaptability or versatility
If factors and isolates of parasitic nematodes are used for treatment, then immune response is modulated, but therapeutic precision and control are inadequate
Solution Approach 1:
The patent segments the complex mixture of nematode secretions into individual chemically defined compounds. By isolating specific ascaroside derivatives rather than using crude extracts, the treatment achieves precise immunomodulation through well-defined molecular structures with known mechanisms of action, improving both precision and controllability.
Solution Approach 2:
The patent creates a series of composite molecular structures by combining the core ascaroside scaffold with various substituted Ring D groups and side chains. These structurally diverse but related compounds work through similar immunomodulatory mechanisms while offering different pharmacokinetic profiles, enabling precise tailoring of treatment to specific clinical needs.

AI summary
Female and male mice were weighed the same day each week in nine mouse rooms representing all three breeding facilities. Weights were measured from 40 females and 40 males in each room; the values shown here represent averages of up to 360 females and 360 mates. Mice were fed a diet containing 6% fat (LabDiet® 5K52 formulation). Values represent mean and one standard deviation. Ages are ±3 days.
