Sphingoid Compounds for Broad-Spectrum Viral Prophylaxis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for addressing viral infections are limited by viral mutation, reduced effectiveness, systemic side effects, and the inability to target multiple virus types, necessitating new compositions and mechanisms for prophylaxis or treatment.
Innovation Solution
The use of sphingoid compounds, such as sphingosine, and enzymes influencing their generation or degradation, like ceramidase and sphingosine kinase inhibitors, to inhibit viral propagation and infection by increasing their concentration in vivo.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If viral targeting mechanisms are used to address viral infections, then viral replication or entry can be inhibited, but viral mutation leads to escape and reduced effectiveness
Solution Approach 1:
The patent applies universality by using sphingoid bases and their metabolites as a multi-functional antiviral mechanism that targets multiple viruses simultaneously. The compounds interfere with viral propagation through a conserved mechanism involving sphingolipid metabolism, making them effective against diverse virus types including rhinovirus, influenza, HIV, and others, thereby reducing the risk of viral escape through mutation.
2Reliability
If inhibitors of acid sphingomyelinase are used to disrupt lipid rafts, then viral entry can be prevented, but unwanted systematic or other side effects occur
Solution Approach 1:
The patent employs short-acting sphingoid base compounds that temporarily modulate sphingolipid metabolism to prevent viral entry without causing long-term systemic effects. These compounds act locally at the cell membrane level to disrupt viral entry mechanisms while being metabolized quickly, minimizing unwanted side effects compared to long-acting enzyme inhibitors.
3Reliability
If conventional antiviral drugs are used to target viral replication, then viral propagation can be inhibited, but the ability to target only a single virus type is limited
Solution Approach 1:
The patent achieves universality by targeting a fundamental host cell mechanism (sphingolipid metabolism) that is exploited by multiple different viruses. Sphingoid bases and their metabolites interfere with viral propagation across diverse virus families by modulating the host's sphingolipid pathway, enabling broad-spectrum antiviral activity rather than virus-specific targeting.
4Adaptability or versatility
If new compositions are developed to address viral infections, then broad spectrum functionality can be achieved, but complexity of the treatment mechanism increases
Solution Approach 1:
The patent uses sphingoid bases and their metabolites as intermediary molecules that mediate between the host cell's sphingolipid metabolism and viral propagation. These intermediaries naturally occur in the body and modulate viral infection by interfering with sphingolipid-dependent viral entry and propagation mechanisms, providing broad-spectrum activity through a relatively simple biochemical pathway rather than complex multi-component systems.

AI summary
Provided are processes for the prevention or treatment of viral infection in a subject. Some aspects provide administration of a sphingoid compound, optionally sphingosine, an active ingredient that activates generation of a sphingoid base, optionally of sphingosine; or an active agent that inhibits the degradation of a sphingoid base, optionally of sphingosine, to a subject such as a human. By increasing the local concentration of sphingosine in a subject or an area of a subject to which the composition is administered such as the nose or interior of the nose or portion thereof, the ability of viruses to infect the subject or cells thereof is reduced thereby treating of preventing infection by the virus.
