Solution Overview

Problem

Current methods for modulating Protein Kinase (PK) activity are inadequate in effectively treating a wide range of diseases and disorders, despite efforts with biomimetic approaches, soluble receptors, RNA ligands, and tyrosine kinase inhibitors.

Innovation Solution

Development of novel thiazolopyrazole compounds that can be administered to patients to modulate PK activity, encompassing various pharmaceutical forms and methods of treatment for diverse diseases and disorders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biomimetic approaches, soluble receptors, RNA ligands, and tyrosine kinase inhibitors are used to modulate PK activity, then some PK activity modulation is achieved, but the effectiveness in treating a wide range of diseases and disorders remains inadequate

Engineering Contradiction:
Improveeffectiveness in treating diseasesVSAvoidbroad spectrum of disease treatment
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent modifies the molecular structure of thiazolopyrazole compounds by changing parameters such as substituting hydrogen atoms with various functional groups (halogens, alkyl groups, aryl groups, heteroaryl groups) at specific positions (R1-R6), adjusting molecular weight, and modifying physical properties like logP and pKa to optimize PK activity modulation across different disease states

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention creates composite molecular structures by combining the thiazolopyrazole core scaffold with various functional groups and substituents, forming a diverse library of compounds (including formulae 1, 2, and 3 with different R groups) that can target multiple PK isoforms and disease pathways simultaneously

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If existing PK modulation methods are applied, then specific disease treatments may be effective, but they fail to provide broad-spectrum therapy across multiple disease types

Engineering Contradiction:
Improvebroad spectrum of therapeutic applicationVSAvoidtherapeutic effectiveness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The thiazolopyrazole compound library is designed with universal applicability through a common core structure that can be modified to target multiple protein kinases (including receptor tyrosine kinases, non-receptor tyrosine kinases, and other PKs) involved in diverse disease pathways, enabling a single compound class to serve multiple therapeutic functions across cancer, autoimmune, inflammatory, and other conditions

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