Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current materials that promote the secretion of antimicrobial peptides often have unfavorable effects or induce the simultaneous secretion of inflammatory cytokines, limiting their effectiveness in treating infections and maintaining skin health.
Innovation Solution
A new compound, represented by Chemical Formula (Ia), is synthesized by dissolving a compound of Chemical Formula (II) or its hydrochloride in an organic solvent with an organic base and adding a compound of Chemical Formula (III) at a specific temperature, which effectively promotes the secretion of human β-defensin and LL-37 without inducing inflammatory cytokines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing materials (organic acids, amino acids) are used to promote antimicrobial peptide secretion, then antimicrobial peptide secretion is enhanced, but inflammatory cytokine secretion is simultaneously induced or unfavorable effects occur
Solution Approach 1:
The patent changes the chemical structure parameters of the secretagogue compound by introducing a specific five-membered ring containing nitrogen (pyrrolidine, pyrroline, or pyridine ring) combined with specific side chains. This structural parameter change enables selective activation of antimicrobial peptide production without triggering inflammatory cytokine release, resolving the contradiction between enhancing peptide secretion and avoiding harmful inflammatory effects.
Solution Approach 2:
The invention creates a composite molecular structure combining a nitrogen-containing five-membered ring core with specific side chains (such as aromatic rings, heteroaromatic rings, or carbonyl groups). This composite molecular design allows the compound to interact selectively with antimicrobial peptide production pathways while avoiding activation of inflammatory pathways, thus resolving the technical contradiction.
2Reliability
If conventional secretagogues are used to increase antimicrobial peptide expression, then infection defense is enhanced, but skin barrier recovery is impaired due to unfavorable effects
Solution Approach 1:
The patent modifies the chemical parameters of the secretagogue by incorporating specific nitrogen-containing five-membered ring structures with controlled side chains. This parameter change enables the compound to selectively stimulate antimicrobial peptide production without the harmful effects that damage skin barriers, thereby enhancing infection defense while preserving skin health.
Solution Approach 2:
The invention converts the potential harm of conventional secretagogues (which cause skin barrier damage) into a benefit by designing molecules that selectively activate antimicrobial peptide production without triggering harmful skin effects. The nitrogen-containing ring structure acts as a selective switch that enables beneficial peptide secretion while blocking harmful inflammatory pathways.
