Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current therapies lack broad-spectrum effectiveness in targeting multiple pathogens that exploit interconnected host protein pathways, leading to limited treatment options for diseases caused by diverse infectious agents.
Innovation Solution
Administration of Bithionol, which inhibits host caspases targeted by various pathogens, including ricin, anthrax toxin, Botulinum neurotoxin A, Pseudomonas aeruginosa exotoxin A, cholera toxin, and Zika virus, thereby reducing pathogenicity across multiple disease pathways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current therapies are used to target pathogens, then specific pathogen treatment is achieved, but broad-spectrum effectiveness against multiple pathogens is limited
Solution Approach 1:
The patent applies universality by developing a single therapeutic agent that can target multiple pathogens through their common exploitation of host caspases. Instead of creating separate treatments for each pathogen, the invention uses one compound (bithionol) that interferes with the shared host pathway (caspase-dependent cell death) utilized by diverse pathogens including bacteria, viruses, and toxins, thereby achieving broad-spectrum effectiveness with a single agent
2Reliability
If pathogen-specific therapies are developed, then treatment precision for individual pathogens is improved, but the ability to treat multiple pathogens simultaneously is reduced
Solution Approach 1:
The patent uses the host caspase pathway as an intermediary target. Rather than directly targeting diverse pathogens with different mechanisms, the invention intermediates through the common host pathway (caspase-dependent cell death) that multiple pathogens exploit. Bithionol acts on this intermediary host pathway, thereby indirectly inhibiting multiple pathogens that would otherwise require different specific treatments
