Small-Molecule SRC-3 Stimulators for Post-Infarction Cardiac Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The adult heart's limited regenerative potential poses a barrier to therapies designed to promote tissue reprogramming and repair after myocardial infarction, leading to progressive cardiac tissue remodeling, loss of myocytes, inflammation, and fibrosis.
Innovation Solution
Small molecule stimulators of steroid receptor coactivator-3 (SRC-3) are administered to promote cardiac protection and vascular regeneration, reducing myocardial infarct size, preventing cardiomyocyte loss, and improving cardiac function by enhancing angiogenesis and vascular perfusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If small molecule SRC-3 stimulators are administered to promote tissue reprogramming and repair, then cardiac protection and vascular regeneration are improved, but the adult heart's limited regenerative potential remains a barrier
Solution Approach 1:
The patent employs small molecule compounds that chemically modulate SRC-3 coactivator activity, changing the biochemical parameters of cardiac cell behavior. These compounds alter gene expression patterns and cellular differentiation states, enabling adult cardiac cells to exhibit regenerative capabilities despite the heart's inherent limited regenerative potential. The chemical intervention transforms the biological parameters of tissue repair and regeneration.
2Reliability
If therapies promote tissue reprogramming and repair after myocardial infarction, then cardiac function is improved, but progressive remodeling, inflammation, and fibrosis worsen
Solution Approach 1:
The patent converts the harmful effects of inflammation and fibrosis into beneficial outcomes by using SRC-3 stimulators to redirect these processes. Instead of allowing uncontrolled inflammation and fibrosis to cause tissue damage, the compounds harness these responses to promote organized tissue repair, angiogenesis, and functional recovery. The harmful inflammatory and fibrotic processes are transformed into constructive regenerative mechanisms through pharmacological modulation of SRC-3 activity.
