Solution Overview

Problem

There are no commercial drugs with selective antagonist activity for both the serotonin 5-HT 2A and 5-HT 7 receptors, limiting their effectiveness in treating neuropsychiatric diseases.

Innovation Solution

Development of a compound with Formula (1) or its pharmaceutically acceptable salt, which exhibits antagonist activity for both the serotonin 5-HT 2A and 5-HT 7 receptors, useful as a medicament for treating neuropsychiatric diseases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate drugs targeting 5-HT2A or 5-HT7 receptors are used, then specific receptor antagonism is achieved, but dual receptor coverage is limited

Engineering Contradiction:
Improvereceptor antagonism effectivenessVSAvoiddual receptor coverage
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent combines two separate therapeutic functions (5-HT2A antagonism and 5-HT7 antagonism) into a single compound (Formula 1). This merging approach allows the drug to simultaneously target both receptors, providing dual coverage that was previously only achievable through combination therapy with separate agents.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The compound of Formula 1 is designed as a multi-functional agent that exhibits antagonist activity against both 5-HT2A and 5-HT7 receptors. This universal design enables a single medication to address multiple neuropsychiatric conditions or provide synergistic effects, enhancing versatility while maintaining reliable receptor antagonism.

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

2Ease of manufacture

If existing commercial drugs are used, then ease of availability is maintained, but selective dual antagonist activity is lacking

Engineering Contradiction:
Improvedrug availabilityVSAvoidselective antagonist activity
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent introduces a novel chemical structure (Formula 1) with specific structural parameters that enable simultaneous binding to both 5-HT2A and 5-HT7 receptors. By optimizing molecular parameters such as the core heterocyclic structure, substituent groups, and spatial configuration, the compound achieves selective dual antagonist activity that distinguishes it from existing commercial drugs.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If combination therapy with multiple drugs is used, then treatment efficacy is enhanced, but treatment complexity increases

Engineering Contradiction:
Improvetreatment efficacyVSAvoidtreatment regimen complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the functions of multiple drugs into a single compound, reducing treatment complexity. Instead of requiring patients to take separate medications for 5-HT2A and 5-HT7 receptor targeting, the compound of Formula 1 provides both therapeutic effects in one agent, simplifying the treatment regimen while maintaining enhanced efficacy.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The multi-functional compound serves as a universal treatment option that can replace combination therapy. By incorporating both 5-HT2A and 5-HT7 antagonist activities in one molecule, it provides a simplified yet effective treatment approach for neuropsychiatric disorders, reducing the complexity associated with managing multiple medications.

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