Solution Overview

Problem

Current treatments for diseases associated with amyloid or amyloid-like proteins, such as Alzheimer's disease and ocular diseases, are limited in effectively targeting amyloid plaque formation and neuronal degradation, with existing medications offering modest benefits and significant side effects, and lack definitive treatments for conditions like age-related macular degeneration and glaucoma.

Innovation Solution

Development of specific compounds that can bind to amyloid proteins, including beta-amyloid, to inhibit aggregation and reduce plaque load, formulated into pharmaceutical compositions for oral, parenteral, or topical administration, designed to cross the blood-brain barrier and target amyloid-related pathological changes in the visual system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing medications are used to treat amyloid-related diseases, then some therapeutic benefit is achieved, but side effects are significant and treatment effectiveness is limited

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidside effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs parameter changes by modifying the chemical structure of compounds to optimize their therapeutic profile. Specifically, the invention uses compounds with specific molecular weights (300-800 Daltons), particular functional groups, and defined lipophilicity parameters (logP values) to enhance blood-brain barrier penetration while maintaining amyloid-binding affinity. This systematic variation of chemical parameters enables achieving both high efficacy and reduced side effects

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent utilizes intermediary compounds that specifically bind to amyloid proteins as mediators between the administered drug and the pathological amyloid deposits. These compounds act as intermediaries by first crossing the blood-brain barrier, then binding to amyloid fibrils with high affinity, and facilitating amyloid clearance or preventing further aggregation, thereby transmitting the therapeutic effect from the systemic circulation to the central nervous system targets

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If current treatments are applied to target amyloid plaque formation, then modest benefits are achieved, but the ability to effectively reduce plaque load is insufficient

Engineering Contradiction:
Improveamyloid plaque burdenVSAvoidtreatment efficacy
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent applies the extraction principle by designing compounds that specifically bind to and extract amyloid proteins from plaques. The compounds have high affinity for amyloid fibrils and can selectively remove or solubilize amyloid deposits from neural tissue without affecting normal proteins. This selective extraction capability enables effective reduction of plaque burden while preserving healthy tissue

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs preliminary action by administering compounds that prevent amyloid aggregation before plaques form or early in the disease process. The compounds interfere with the nucleation and elongation steps of amyloid formation, preventing the development of large plaque deposits. This preventive approach is more effective than attempting to remove established plaques

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If medications are designed to cross the blood-brain barrier, then central nervous system targeting is achieved, but drug delivery efficiency is reduced

Engineering Contradiction:
Improvedrug deliveryVSAvoidblood-brain barrier penetration
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent systematically optimizes molecular parameters to achieve optimal blood-brain barrier penetration. Compounds are designed with specific molecular weight ranges (300-800 Daltons), controlled lipophilicity (logP values between 1-4), and particular hydrogen bonding characteristics. These parameter optimizations enable efficient passive diffusion across the blood-brain barrier while maintaining sufficient solubility in aqueous circulation

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite molecular structures that combine hydrophilic and hydrophobic moieties in specific ratios and configurations. These amphipathic compounds can interact with both the aqueous blood plasma and the lipid-rich blood-brain barrier membrane, facilitating efficient transport. The composite structure includes amyloid-binding domains and membrane-permeation domains working in concert

Inventive Principle:
Principle #40Composite materials
