Pyridoxamine Derivatives Inhibit AGE ALE Formation

Solution Overview

Problem

There is a need for additional treatment options to inhibit the development of advanced glycation end-products (AGE) and advanced lipoxidation end-products (ALE) associated complications, particularly in patients with hyperglycemia and/or hyperlipidemia, as current therapies are limited in effectively addressing these conditions.

Innovation Solution

The development of novel compounds and pharmaceutical compositions that inhibit the formation of AGEs and ALEs, which are administered to subjects suffering from hyperglycemia and/or hyperlipidemia to treat or prevent complications such as diabetic nephropathy, atherosclerosis, and dialysis-related disorders, by interfering with the oxidative breakdown of Amadori intermediates and binding with redox metal ions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current therapies are used to treat hyperglycemia and hyperlipidemia, then existing treatment options are available, but they are limited in effectively addressing AGE and ALE associated complications

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the therapeutic approach by developing distinct compounds with specific molecular structures (formula I) that selectively inhibit AGE and ALE formation pathways. This segmentation provides specialized treatment options for different complications rather than using broad-spectrum therapies.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs composite molecular structures combining pyridoxamine derivatives with specific substituents (formula I) to create compounds that simultaneously address multiple pathogenic mechanisms including glycation, lipoxidation, and oxidative stress, thereby providing versatile treatment for various complications.

Inventive Principle:
Principle #40Composite materials

2Reliability

If pyridoxamine is used to inhibit AGE and ALE formation, then it shows therapeutic benefit in animal models, but further treatment options are needed

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent modifies the molecular parameters of pyridoxamine by introducing various substituents at specific positions (R1-R6, G, X, Y, Z) to optimize binding affinity and selectivity for AGE/ALE inhibition while reducing off-target effects, thereby expanding the therapeutic toolkit beyond plain pyridoxamine.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies local quality modifications by placing specific functional groups at particular positions on the molecular scaffold (e.g., heterocyclic groups at G position, alkyl chains at R positions) to enhance specific interactions with target proteins involved in AGE/ALE formation pathways.

Inventive Principle:
Principle #3Local quality
