Solution Overview

Problem

Current modulators of adenosine receptors are nonselective, leading to adverse effects in treatments, and there is a need for subtype selective adenosine receptor agonists and antagonists to effectively manage various diseases and disorders mediated by adenosine A2A and A2B receptors.

Innovation Solution

Development of compounds that selectively modulate the adenosine A2A and A2B receptors, including their synthesis and pharmaceutical compositions, to inhibit these receptors and potentially affect adenylyl cyclase activity, offering therapeutic benefits in cancer and immune-related disorders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If nonselective adenosine receptor modulators are used, then broad receptor coverage is achieved, but adverse effects increase due to lack of subtype selectivity

Engineering Contradiction:
Improvereceptor coverageVSAvoidadverse effects
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the adenosine receptor modulator market into subtype-specific agents, developing compounds that selectively target A2A or A2B receptors rather than acting on all adenosine receptor subtypes. This segmentation allows for tailored therapeutic effects while minimizing off-target adverse effects associated with nonselective modulators.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by designing molecules with specific structural features that confer selectivity for particular adenosine receptor subtypes. By modifying local molecular properties (such as substituent groups on the purine core), the compounds achieve preferential binding to A2A or A2B receptors, thereby producing localized therapeutic effects without activating other receptor subtypes that cause adverse effects.

Inventive Principle:
Principle #3Local quality

2Object-affected harmful factors

If subtype selective adenosine receptor modulators are developed, then adverse effects are minimized, but development complexity increases

Engineering Contradiction:
Improveadverse effectsVSAvoiddevelopment complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent employs parameter changes by systematically varying molecular parameters (such as substituent types, positions, and configurations on the purine core) to optimize subtype selectivity. By adjusting these chemical parameters, the development process identifies compounds with desired selectivity profiles, balancing the complexity of developing selective agents against the benefit of reduced adverse effects.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If selective A2A and A2B receptor modulators are used, then therapeutic efficacy for specific diseases is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvetherapeutic efficacyVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent segments the therapeutic approach into disease-specific or condition-specific selective modulator regimens. By matching particular compounds with specific indications (e.g., A2A selectivity for Parkinson's, A2B selectivity for inflammatory conditions), the patent optimizes therapeutic efficacy for each application while streamlining manufacturing processes to focus on producing the right compound for the right indication rather than attempting universal production.

Inventive Principle:
Principle #1Segmentation
