Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing technologies are used, then general neuroprotection is provided, but specific astrocyte proliferation activity is not achieved

Engineering Contradiction:

Improveastrocyte proliferation activityVSAvoidcell type specificity

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The cyclic peptide derivative is designed with specific local structural characteristics (Formula 1 configuration including R1-R10 substituents and A ring structure) that confer selective affinity for astrocytes, enabling differentiated interaction with this specific cell type while maintaining the overall cyclic peptide framework

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If conventional compounds are used, then broad neurological support is provided, but targeted astrocyte modulation is not achieved

Engineering Contradiction:

Improveastrocyte targeting capabilityVSAvoidcompound specificity

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The compound structure in Formula (1) utilizes variable substituent parameters (R1 through R10 representing different hydrocarbon groups, hydrogen atoms, and functional groups) and ring structure parameters (A being O, NH, or S) to optimize the balance between molecular diversity for astrocyte targeting and structural definition for specific biological activity
