Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If Pin1 enzyme is inhibited, then cancer progression and metastasis are suppressed, but the compound structure and synthesis complexity increase

Engineering Contradiction:
Improveanticancer efficacyVSAvoidcompound structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent modifies molecular parameters of Pin1 inhibitors by changing substituent groups (R1-R6, Ar, L1-L3) in the core compound structure. This allows optimization of binding affinity and selective inhibition while managing structural complexity through systematic parameter variation rather than creating entirely new molecular architectures.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The compound structure is divided into distinct functional segments: a core scaffold (formula 1), variable substituent groups (R1-R6), and linkage moieties (L1-L3). This segmentation enables independent optimization of each component's contribution to Pin1 inhibition while simplifying the overall synthesis process by assembling pre-defined modular units.

Inventive Principle:
Principle #1Segmentation

2Reliability

If Pin1 inhibitor compounds are developed, then therapeutic effectiveness improves, but manufacturing and synthesis difficulty increase

Engineering Contradiction:
Improvetherapeutic effectivenessVSAvoidsynthesis feasibility
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent establishes preliminary synthetic routes by defining the core compound structure (formula 1) and its precursor compounds before final assembly. This preliminary planning allows for optimized synthesis sequences, pre-preparation of building blocks, and anticipation of potential synthesis bottlenecks, thereby improving manufacturability while maintaining therapeutic effectiveness.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The core compound structure serves multiple functions: it provides the basic Pin1 inhibition mechanism, acts as a scaffold for various substituent groups, and can be adapted to different therapeutic applications (cancer, inflammatory diseases, metabolic diseases). This multi-functionality reduces the need for entirely separate synthesis routes for different applications.

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

3Reliability

If Pin1 is overexpressed in cancer cells, then tumor growth and metastasis are promoted, but the lack of effective inhibitors limits treatment options

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidtreatment options
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent develops a universal Pin1 inhibition platform (formula 1) that can be applied across multiple disease types (cancer, inflammatory diseases, metabolic diseases). This single inhibitory mechanism addresses the overexpression of Pin1 in various pathological conditions, providing versatile treatment options rather than requiring disease-specific inhibitors.

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

Solution Approach 2:

By systematically varying substituent parameters (R1-R6, Ar, L1-L3) in the core structure, the patent generates a library of compounds with different binding affinities and selectivities. This parameter variation provides multiple treatment options targeting Pin1 overexpression in different disease contexts, adapting the same basic mechanism to various therapeutic needs.

Inventive Principle:
Principle #35Parameter changes

AI summary

The present invention relates to a method for preparing a biomaterial having selectively functionalized tyrosine, a biomaterial having selectively functionalized tyrosine, and a pharmaceutical composition containing the same as an active ingredient. The method for preparing a biomaterial to which a compound represented by formula 2 is coupled, of the present invention, allows the compound represented by formula 2 to be selectively coupled, in a high yield in a biomaterial, to tyrosine, which is present on the surface of an aqueous solution such that the coupling thereof to amino acids other than tyrosine does not occur and, when only one tyrosine is present, heterogeneous mixtures are not present and the inherent activity of the biomaterial is maintained, and thus the compound can be effectively used as a pharmaceutical composition containing a biomaterial drug as an active ingredient. In addition, the method can selectively functionalize tyrosine, and thus can be effectively used for tyrosine functionalization in a biomaterial.
