Solution Overview

Problem

Current treatments for diabetes and obesity often come with significant side effects due to the limitations of existing drugs, and there is a need for more stable and effective compounds that can inhibit sodium-dependent glucose co-transporters without enzymatic degradation.

Innovation Solution

Development of CF2-analogues of aryl, heteroaryl, O-aryl, and O-heteroaryl glycosides where the intracyclic glycosidic oxygen is replaced by a carbon atom carrying two fluorine atoms, providing stability and mimicking the oxygen atom's function, thereby acting as SGLT inhibitors and Tyrosinase inhibitors for cosmetic applications.

1Reliability

If existing SGLT inhibitor drugs are used to treat diabetes and obesity, then glucose co-transporter inhibition is achieved, but significant side effects occur due to enzymatic degradation and limited stability

Engineering Contradiction:
Improvestability against enzymatic degradationVSAvoidside effects
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies parameter changes by replacing the intracyclic glycosidic oxygen atom with a carbon atom carrying two fluorine atoms (CF2 group). This chemical modification transforms the molecular structure to create stable analogues that resist enzymatic degradation while maintaining SGLT inhibition activity, thereby improving reliability and reducing side effects associated with enzyme-mediated breakdown of conventional glycosides

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention creates stable copies of natural O-aryl and O-heteroaryl glycosides by synthesizing CF2-analogues that mimic the oxygen atom's function. These difluorinated carbon analogues serve as stable replicas that retain the biological activity of the original compounds while being resistant to enzymatic hydrolysis, thus solving the stability problem without losing therapeutic efficacy

Inventive Principle:
Principle #26Copying

2Reliability

If new SGLT inhibitor compounds are developed to reduce side effects, then stability and selectivity improve, but the complexity of compound synthesis increases

Engineering Contradiction:
Improveselectivity and stabilityVSAvoidsynthesis process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The synthesis approach is segmented into modular steps: first constructing the difluorinated carbasugar core structure with the CF2 group, then separately synthesizing the aryl or heteroaryl moieties, and finally coupling these pre-prepared fragments together. This segmentation of the synthesis process into independent modules simplifies the overall complexity while maintaining the advanced stability and selectivity of the final compounds

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs preliminary action by pre-synthesizing and characterizing the difluorinated carbasugar intermediates and aryl/heteroaryl building blocks before final assembly. This advance preparation of standardized intermediates with known structures and properties streamlines the subsequent coupling reactions, reducing the overall synthesis complexity while ensuring the desired stability and selectivity in the final products
