Solution Overview

Problem

Current S-adenosyl-L-methionine (SAMe) salts face stability issues at ambient temperature, leading to degradation and gastrointestinal discomfort, with existing stabilizing salts not effectively addressing these problems, and there is a lack of indole-3-propionic acid (IPA) salts in previous patents.

Innovation Solution

Development of stable indole-3-propionic acid (IPA) salts of S-adenosyl-L-methionine, prepared using acids like hydrochloric acid, sulfuric acid, or phosphoric acid, which provide superior stability and reduced gastrointestinal side effects, along with methods for their synthesis and therapeutic use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If existing stabilizing salts are used for SAMe, then stability is improved, but gastrointestinal discomfort occurs

Engineering Contradiction:
ImprovestabilityVSAvoidgastrointestinal discomfort
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical parameter of the stabilizing salt from conventional options to indole-3-propionic acid salt, which fundamentally alters the properties of the stabilization system. This parameter change achieves both stability improvement and elimination of gastrointestinal side effects by selecting a salt with favorable pharmacological properties.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces a new class of stabilizing salt (indole-3-propionic acid salt) that serves as a temporary but effective stabilization mechanism. The salt provides the necessary stability during storage and administration, then does not persist to cause long-term adverse effects, analogous to using a disposable solution that fulfills its purpose without lingering harm.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Ease of operation

If SAMe is stored at ambient temperature, then ease of operation is improved, but degradation occurs

Engineering Contradiction:
Improveease of operationVSAvoiddegradation
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent changes the physical parameter of storage temperature from controlled refrigeration to ambient temperature by introducing a stabilizing salt. This parameter change in the storage conditions is enabled by the chemical stabilization provided by the indole-3-propionic acid salt, allowing easier operation without special temperature control while preventing degradation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The stabilizing salt acts as an intermediary substance between SAMe and the ambient environment. It mediates the interaction by protecting SAMe from degradation factors present at ambient temperature, such as oxidation and hydrolysis, thereby enabling stable storage without refrigeration.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If conventional salts are used to stabilize SAMe, then stability is improved, but manufacturing complexity increases

Engineering Contradiction:
ImprovestabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent changes the chemical parameter of the stabilizing agent to indole-3-propionic acid salt, which simplifies the manufacturing process. This parameter change eliminates the need for complex purification steps and special handling procedures required by other stabilizing salts, thereby reducing manufacturing complexity while maintaining stability.

Inventive Principle:
Principle #35Parameter changes
