15-PGDH Modulator Compositions for Tissue-Specific Prostaglandin Control

Solution Overview

Problem

Current therapies for modulating short-chain dehydrogenase (SCD) activity, particularly 15-PGDH, are limited in effectively addressing conditions related to prostaglandin levels and associated disorders such as colon tumors, thrombin-mediated cell death, and conditions benefiting from PGE2 activity like hair density and dermal wound healing.

Innovation Solution

Development of specific 15-PGDH inhibitors and activators that can modulate prostaglandin levels by inhibiting or activating the enzyme, utilizing compounds with defined structural formulas to target SCD activity in tissues or blood, thereby influencing prostaglandin levels and treating related disorders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If 15-PGDH enzyme activity is increased to inactivate prostaglandins, then prostaglandin levels decrease, but beneficial effects on hair density, dermal wound healing, and bone formation are reduced

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by developing tissue-specific 15-PGDH modulators that can selectively increase enzyme activity in certain tissues (e.g., colon, lung, liver) while maintaining or preserving prostaglandin levels in other tissues (e.g., skin, bone, hair follicles). This allows differential control of prostaglandin metabolism in different anatomical locations, enabling therapeutic benefits in target tissues without compromising beneficial effects in non-target tissues.

Inventive Principle:
Principle #3Local quality

2Object-affected harmful factors

If 15-PGDH inhibitors are used to increase prostaglandin levels, then beneficial effects on hair growth and wound healing improve, but risk of colon tumor development increases

Engineering Contradiction:
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent segments the therapeutic effect by creating compounds that selectively modulate 15-PGDH activity in specific tissues. The segmented approach allows increasing prostaglandin levels in tissues requiring beneficial effects (skin, hair follicles) while maintaining low prostaglandin levels in colon tissue to prevent tumor development. This is achieved through tissue-specific pharmacokinetic properties or selective receptor binding of the modulators.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by developing modulators with differential tissue distribution and selectivity. The compounds are designed to accumulate or exert greater effect in specific tissues (e.g., skin for wound healing, hair follicles for hair growth) while having minimal impact on colon tissue. This spatially differentiated modulation resolves the contradiction between beneficial effects and tumor risk.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If broad-spectrum SCD inhibitors are used to treat multiple disorders, then therapeutic versatility improves, but off-target effects and side effects increase

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by developing SCD modulators with tissue-specific selectivity. Each compound is designed to preferentially modulate 15-PGDH activity in specific tissues relevant to the targeted indication (e.g., lung tissue for COPD, liver tissue for metabolic disorders, skin tissue for wound healing). This tissue-specific action provides therapeutic versatility across multiple disorders while minimizing off-target effects by avoiding broad-spectrum inhibition.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses tissue-specific transporters, binding proteins, or metabolic pathways as intermediaries to deliver the SCD modulators selectively to target tissues. These intermediaries facilitate preferential accumulation or activation of the compounds in specific organs, enabling broad therapeutic applicability while maintaining selectivity and reducing off-target effects.

Inventive Principle:
Principle #24Intermediary (Mediator)
