Solution Overview

Problem

There are no effective drugs available for the treatment or prevention of abnormal immune activation and incomplete immune reconstitution associated with AIDS, which are significant contributors to the progression and complications of the disease.

Innovation Solution

Utilizing (5R)-5-hydroxytriptolide to inhibit NF-κB activity and CD4+ T-cell activation, thereby addressing abnormal immune activation and incomplete immune reconstitution in AIDS patients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If triptolide is used for immunosuppression in AIDS, then immunosuppressive activity is improved, but toxicity and side effects increase

Engineering Contradiction:
Improveimmunosuppressive activityVSAvoidtoxicity and side effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by modifying the chemical structure of triptolide at position 5 to create (5R)-5-hydroxytriptolide. This structural modification changes the pharmacological parameters of the compound, maintaining immunosuppressive activity while reducing toxicity and side effects, thereby resolving the contradiction between therapeutic efficacy and safety

Inventive Principle:
Principle #35Parameter changes

2Reliability

If no specific medicament is used for abnormal immune activation in AIDS, then existing antiviral therapy continues, but immune reconstitution remains incomplete and mortality rate increases

Engineering Contradiction:
Improveimmune reconstitutionVSAvoidmortality rate
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and addresses the specific problem of abnormal immune activation as a separate treatable condition from HIV viral replication itself. By identifying NF-κB pathway inhibition as the specific mechanism to address immune activation, the patent enables targeted treatment of this previously unaddressed aspect of AIDS pathology, improving immune reconstitution and reducing mortality
