Solution Overview

Problem

The production of monosaccharides and oligosaccharides is costly and complex, especially when mass production is required, and their mimics, or glycomimetics, do not significantly reduce production costs despite potentially improving biological properties.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If monosaccharides and oligosaccharides are produced through conventional synthesis methods, then the desired biological compounds are obtained, but the production cost and complexity increase significantly

Engineering Contradiction:
Improvebiological activityVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent creates simplified copies (glycomimetics) that replicate the essential biological function of complex monosaccharides and oligosaccharides. Instead of synthesizing the complete natural structures, the invention uses cyclohexane derivatives that copy only the critical features needed for E-selectin binding, dramatically reducing synthesis complexity while maintaining biological activity

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent employs inexpensive cyclohexane-based building blocks and commercially available reagents to construct glycomimetics. The simplified molecular structure allows for cost-effective synthesis using standard chemical techniques, making the compounds economically viable compared to expensive natural product isolation or complex total synthesis

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

2Reliability

If glycomimetics are developed to improve biological properties, then biological activity may be enhanced, but production cost does not significantly reduce

Engineering Contradiction:
Improvebiological activityVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent systematically varies structural parameters of the cyclohexane core and substituent groups to optimize both biological activity and synthesizability. By changing parameters such as hydroxyl group positioning, acetal bridge configuration, and side chain composition, the invention achieves high E-selectin affinity while maintaining simple, scalable synthesis routes

Inventive Principle:
Principle #35Parameter changes

3Reliability

If complex oligosaccharide structures are synthesized, then biological function is achieved, but production time and process complexity increase

Engineering Contradiction:
Improvebiological functionVSAvoidproduction time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent divides the oligosaccharide mimic into discrete modular components (cyclohexane core, acetal bridge, hydroxyl groups, and substituent chains) that can be synthesized and assembled independently. This segmentation allows for parallel synthesis of building blocks and simplifies the overall production process, reducing total manufacturing time while maintaining biological function

Inventive Principle:
Principle #1Segmentation
