Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current opioid receptor modulators, such as morphine and fentanyl, while effective for pain management, are limited by significant side effects including respiratory depression, constipation, drug tolerance, physical dependence, and addiction, necessitating the development of new compounds with reduced side effects for various medical conditions.
Innovation Solution
Development of polycyclic amines and their prodrugs with specific structures, including pharmaceutically acceptable salts, that modulate opioid receptors to treat a wide range of conditions including pain, cardiac disorders, mental illness, and cancer, without the severe side effects of existing opioids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If opioid receptor modulators such as morphine and fentanyl are used for pain management, then analgesic efficacy is improved, but side effects including respiratory depression, constipation, drug tolerance, physical dependence, and addiction increase
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of opioid receptor modulators through polycyclic amine compounds with specific molecular configurations (Formula I structures). These structural parameter changes aim to alter the pharmacological profile to reduce side effects while maintaining analgesic efficacy. The compounds feature varied substituents (A, Y, Q, W, G, Z, R1-R6) that can be optimized to tune receptor selectivity and minimize adverse effects.
Solution Approach 2:
The invention employs composite molecular structures combining polycyclic amine cores with diverse substituent groups. This composite approach creates hybrid compounds that target opioid receptors with improved selectivity, potentially separating analgesic effects from side effect profiles through multi-component molecular design.
2Object-generated harmful factors
If new opioid receptor modulators are developed to reduce side effects, then safety profile is improved, but drug efficacy may be compromised
Solution Approach 1:
The patent applies local quality by introducing specific functional groups and substituents at particular positions on the polycyclic amine core structure. Each substituent (A, Y, Q, W, G, Z, R1-R6) can be independently optimized to confer specific properties: some regions enhance receptor binding for efficacy, while others reduce off-target effects to minimize side effects.
Solution Approach 2:
The invention incorporates dynamic elements through prodrug designs that can be converted to active compounds in vivo. This allows the drug to remain inactive during administration (reducing side effects) and become active only at the target site or under specific physiological conditions, thereby maintaining efficacy while improving safety.
3Reliability
If polycyclic amine compounds with complex structures are synthesized, then receptor selectivity is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the complex polycyclic amine structure into modular components that can be synthesized separately and then assembled. The core polycyclic amine structure serves as a building block that can be functionalized with various substituents through standardized chemical reactions, simplifying the manufacturing of diverse analogs.
Solution Approach 2:
The invention employs universal synthetic pathways that can produce multiple polycyclic amine derivatives using common starting materials and reaction sequences. The core structure and substituent attachment points are designed to accommodate various functional groups through通用 (universal) chemical transformations, reducing manufacturing complexity despite structural diversity.
