Solution Overview

Problem

Current TRPM8 modulators face deficiencies in strength of effect, duration of effect, skin/mucosa irritation, odor, taste, solubility, and volatility, limiting their application in cosmetics, nutrition, textiles, OTC products, and pharmaceuticals.

Innovation Solution

Development of novel TRPM8 receptor modulators, including specific compounds and methods for their use, which can act as agonists or antagonists to induce a sensation of coldness, suitable for various applications such as cosmetics, pharmaceuticals, and textiles, with improved properties over existing modulators.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If menthol is used as a TRPM8 modulator, then the cooling effect is achieved, but skin/mucosa irritation and anesthetic effect occur at elevated concentrations

Engineering Contradiction:
Improvecooling effectVSAvoidskin/mucosa irritation
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent develops novel TRPM8 modulators that act as short-acting alternatives to menthol, providing the desired cooling effect without the prolonged irritation and anesthetic effects associated with elevated menthol concentrations. These compounds are designed to be metabolized or eliminated more quickly, reducing cumulative harmful effects on skin and mucosa.

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

Solution Approach 2:

The invention changes the chemical parameters of the TRPM8 modulator by developing structurally unrelated compounds with different physicochemical properties compared to menthol. These novel modulators maintain TRPM8 activation capability while having reduced affinity for irritant receptors and different volatility profiles, thereby reducing irritation and anesthetic side effects.

Inventive Principle:
Principle #35Parameter changes

2Temperature

If high concentrations of TRPM8 modulators are used to enhance cooling effect, then the sensation of coldness is intensified, but irritation and anesthetic effect increase

Engineering Contradiction:
Improvesensation of coldnessVSAvoidanesthetic effect
Core Design Contradiction:
TemperatureVSObject-generated harmful factors

Solution Approach 1:

The novel modulators are designed with shorter duration of action, allowing for more frequent application at lower concentrations to achieve cumulative cooling effects without building up anesthetic side effects. This enables sustained use without the progressive numbness associated with high-concentration menthol.

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

Solution Approach 2:

The patent modifies the concentration-response relationship by introducing compounds with higher potency at lower concentrations, allowing effective cooling sensation to be achieved at concentrations that do not trigger anesthetic effects. The novel modulators have optimized affinity for TRPM8 compared to their affinity for other receptors that mediate anesthetic effects.

Inventive Principle:
Principle #35Parameter changes

3Temperature

If existing TRPM8 modulators are used, then cooling effect is produced, but deficiencies in strength of effect, duration of effect, solubility, and volatility remain

Engineering Contradiction:
Improvecooling effectVSAvoidstrength of effect
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The patent systematically varies chemical parameters of the modulator molecules to optimize multiple properties simultaneously. The novel compounds feature modified molecular weight, hydrophobicity, and functional groups that improve solubility in cosmetic and pharmaceutical formulations while maintaining or enhancing TRPM8 activation potency and extending duration of effect through optimized metabolic stability.

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The novel modulators provide enhanced efficacy and reduced side effects, extending the cooling effect on skin or mucosa compared to traditional menthanecarboxylic acid N-ethylamide, and are suitable for diverse applications including skincare, haircare, pharmaceuticals, and textiles.

Implementation Method 1

in the cell membrane, forms pores (in each case 4 units combine to give a tetramer), which selectively allow Ca2+ ions to pass

Methodology Applied
Scientific EffectIon channel permeation: Permeation

Implementation Method 2

it has been shown that it acts as a natural modulator of the receptor TRPM8. By applying menthol, TRPM8 is activated, which brings about a Ca2+ influx into the cold-sensitive neurons

Methodology Applied
Scientific EffectReceptor modulation:

Implementation Method 3

Low temperatures (preferably 10-25° C.) stimulate this receptor, resulting in a signal transduction which is interpreted by the nervous system as a sensation of coldness

Methodology Applied
Scientific EffectThermosensation:
