Solution Overview

Problem

Current anti-platelet medications for preventing and treating thrombotic diseases often interfere with normal hemostasis, increasing the risk of bleeding, and have complex structures and high production costs, limiting their effectiveness and efficiency.

Innovation Solution

A novel terpene derivative-based PAR1 inhibitor is developed, using andrographolide as a starting material for structural modification, resulting in a compound with a clear target, low bleeding risk, and reduced preparation costs, which can be used to treat thrombotic diseases without affecting normal hemostasis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional anti-platelet medications (TXA2 or ADP inhibitors) are used to inhibit platelet aggregation, then thrombotic diseases can be prevented and treated, but normal hemostasis is affected and bleeding risk increases

Engineering Contradiction:
Improveanti-thrombotic efficacyVSAvoidbleeding risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and targets only the pathological thrombin-mediated platelet activation pathway by specifically inhibiting PAR1 receptors, while leaving the normal hemostatic pathways (TXA2 and ADP) intact. This selective extraction of the pathological mechanism allows anti-thrombotic treatment without compromising normal hemostasis, thereby reducing bleeding risk while maintaining anti-thrombotic efficacy

Inventive Principle:
Principle #2Taking out (Extraction)

2Object-affected harmful factors

If Vorapaxar is used as a PAR1 inhibitor to block platelet aggregation, then the risk of accidental bleeding is reduced, but the structure becomes complicated and preparation cost increases

Engineering Contradiction:
Improvebleeding risk reductionVSAvoidmolecular structure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent replaces the complex, expensive Vorapaxar molecule with simpler terpene derivative structures that are cheaper to produce. Although the new compounds have simpler structures, they maintain effective PAR1 inhibition and bleeding risk reduction, achieving the same therapeutic goal with more economical molecular designs

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent changes the molecular parameters by using natural terpene derivatives with simpler structures compared to Vorapaxar. By modifying structural parameters (molecular weight, complexity, chiral centers) while maintaining biological activity, the patent achieves reduced preparation cost and simplified structure while preserving the bleeding risk reduction benefit

Inventive Principle:
Principle #35Parameter changes

3Reliability

If Vorapaxar is used to inhibit PAR1, then anti-coagulation activity is improved, but the synthetic route becomes long and preparation cost increases

Engineering Contradiction:
Improveanti-coagulation activityVSAvoidpreparation cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent utilizes naturally occurring terpene derivatives as starting materials that already possess the necessary structural features for PAR1 inhibition. By leveraging nature's own molecular designs, the patent eliminates the need for complex multi-step synthesis required for Vorapaxar, thereby reducing preparation cost while maintaining anti-coagulation activity

Inventive Principle:
Principle #25Self-service
