Solution Overview

Problem

Existing EED inhibitors, such as compound A, have poor water solubility and fluidity, leading to low dissolution and bioavailability, which limits their therapeutic efficacy in treating EED-mediated diseases like cancer.

Innovation Solution

A stable solid dispersion is developed comprising an EED inhibitor, particularly compound A, combined with a polymeric carrier like HPMCAS LG or Eudragit, to enhance solubility and bioavailability through amorphous crystal conversion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If EED inhibitor compound A is used directly, then it exhibits anti-tumor activity, but it has poor water solubility and low bioavailability

Engineering Contradiction:
ImprovebioavailabilityVSAvoidwater solubility
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent changes the physical and chemical parameters of the EED inhibitor by converting it from a crystalline state to an amorphous state through solid dispersion technology. This parameter change dramatically improves water solubility and bioavailability while maintaining the anti-tumor activity of the compound

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite material system by combining the EED inhibitor with polymeric carriers (such as HPMCAS LG or Eudragit) to form solid dispersions. This composite approach enhances the solubility and bioavailability of the poorly water-soluble drug compound

Inventive Principle:
Principle #40Composite materials

2Ease of operation

If EED inhibitor compound A is used directly, then it exhibits anti-tumor activity, but it has poor fluidity

Engineering Contradiction:

Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent changes the physical state parameter of the EED inhibitor from crystalline to amorphous through solid dispersion, which significantly improves fluidity and processability while preserving the molecular structure and anti-tumor activity of the active compound

Inventive Principle:
Principle #35Parameter changes

3Reliability

If solid dispersion is used to improve solubility, then bioavailability increases, but formulation complexity increases

Engineering Contradiction:
ImprovebioavailabilityVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses polymeric carriers as intermediary substances to facilitate the transformation of the EED inhibitor into a highly soluble amorphous state. These carriers act as mediators that stabilize the amorphous form and enhance solubility without requiring complex formulation processes

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies parameter changes by controlling the physical state of the drug in the solid dispersion system, transforming it from crystalline to amorphous. This single parameter change achieves significant bioavailability improvement with relatively simple formulation approaches

Inventive Principle:
Principle #35Parameter changes
