Solution Overview

Problem

Current treatments for type 2 diabetes, such as sulfonylureas and GLP-1 analogs, either induce sustained hyperinsulinemia with side effects or require parenteral administration, failing to restore normal glucose-induced insulin secretion and preserve beta cell mass effectively.

Innovation Solution

Development of specific pyridopyrazinone derivatives that stimulate insulin secretion in response to glucose levels, addressing the defects in insulin secretion and beta cell function in type 2 diabetes without causing hyperinsulinemia or requiring parenteral administration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If sulfonylureas are used to induce insulin secretion, then insulin release is increased, but sustained hyperinsulinemia and side effects occur

Engineering Contradiction:
Improveinsulin secretionVSAvoidhyperinsulinemia and side effects
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The pyridopyrazinone derivatives act as glucose-dependent insulin secretagogues, meaning they stimulate insulin secretion only in the presence of elevated glucose levels. This glucose-dependent mechanism provides physiological feedback control, preventing sustained hyperinsulinemia and associated side effects while maintaining effective insulin secretion when needed.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The invention changes the key parameter of insulin secretion from being drug-driven (sulfonylureas) to being glucose-driven (physiological response). This parameter change transforms the secretion profile from sustained and non-selective to pulsatile and glucose-responsive, eliminating hyperinsulinemia while preserving beneficial insulin release.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If GLP-1 analogs are used to restore normal insulin release profile, then beta cell function is preserved, but parenteral administration is required

Engineering Contradiction:
Improvebeta cell function preservationVSAvoidadministration route
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention substitutes the peptide-based GLP-1 mechanism with a small molecule compound that achieves similar physiological effects through oral administration. This replaces the parenteral delivery system with an oral tablet, eliminating injection requirements while maintaining glucose-dependent insulin secretion and beta cell protective effects.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention changes the molecular class from peptide (GLP-1 analog) to small molecule (pyridopyrazinone derivative), which fundamentally alters the administration route parameter from parenteral to oral, improving patient compliance and ease of use while preserving the therapeutic effect.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If sulfonylureas are used to stimulate insulin secretion, then blood glucose is lowered, but beta cell exhaustion and secondary failure occur

Engineering Contradiction:
Improveblood glucose controlVSAvoidbeta cell mass preservation
Core Design Contradiction:
ProductivityVSDuration of action of stationary object

Solution Approach 1:

The glucose-dependent mechanism of pyridopyrazinone derivatives provides physiological feedback that limits insulin secretion to periods of hyperglycemia. This prevents prolonged and excessive insulin release that causes beta cell exhaustion, thereby preserving beta cell mass and function over the long term while maintaining effective blood glucose control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The invention transforms insulin secretion from continuous (sulfonylurea-induced) to periodic and pulsatile (glucose-dependent). This periodic action allows beta cells to rest during euglycemic periods, preventing exhaustion and maintaining long-term secretory capacity while achieving effective glucose control during hyperglycemic episodes.

Inventive Principle:
Principle #19Periodic action
