Isocitrate Dehydrogenase Inhibitor Targeting Mutant IDH2

Solution Overview

Problem

Current treatments for cancers characterized by mutant isocitrate dehydrogenase 2 (IDH2) lack effective inhibitors that can specifically target and inhibit the enzyme's aberrant activity, leading to the production of 2-Hydroxyglutarate, which contributes to cancer development.

Innovation Solution

Development of a compound represented by formula (I), a pharmaceutically acceptable salt, crystal, or solvate, which acts as a potent inhibitor of mutant IDH2, inhibiting its enzyme activity and tumor cell growth, specifically designed to target mutations at residues R140 or R172.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current treatments are used for cancers with mutant IDH2, then general cancer treatment is provided, but specific inhibition of mutant IDH2 enzyme activity and 2-Hydroxyglutarate production is not achieved

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The compound is designed to specifically target and bind to the mutant IDH2 enzyme structure, exploiting local structural differences caused by mutations at residues R140 or R172. The molecular structure contains specific functional groups that interact with the mutant active site, providing selective inhibition while leaving wild-type IDH2 unaffected.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention changes the chemical parameters of the inhibitor to optimize binding affinity for mutant IDH2. By modifying molecular weight, functional group composition, and stereochemical configuration, the compound achieves enhanced specificity and potency against mutant IDH2 compared to existing inhibitors.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If IDH2 inhibitors are developed to reduce 2-Hydroxyglutarate production, then cancer development is inhibited, but the complexity of drug development increases

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The compound serves multiple therapeutic functions simultaneously: it inhibits mutant IDH2 enzyme activity, reduces 2-Hydroxyglutarate production, and suppresses tumor cell growth. This multi-functionality is achieved through a single molecular entity that targets the root cause of the disease mechanism.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The inhibitor acts as an intermediary molecule that blocks the interaction between mutant IDH2 and its substrate alpha-ketoglutarate. By occupying the active site, the compound mediates the inhibition of the neomorphic activity that produces excessive 2-Hydroxyglutarate, thereby preventing cancer development.

Inventive Principle:
Principle #24Intermediary (Mediator)
