Abstract:
Natural flavonoids may be utilized as an important therapy for cardiovascular diseases (CVDs) caused by intestinal barrier damage. More research is being conducted on the protective properties of natural flavonoids against intestinal barrier injury, although the underlying processes remain unknown. Thus, the purpose of this article is to present current research on natural flavonoids to reduce the incidence of CVDs by protecting intestinal barrier injury, with a particular emphasis on intestinal epithelial barrier integrity (inhibiting oxidative stress, regulating inflammatory cytokine expression, and increasing tight junction protein expression). Furthermore, the mechanisms driving intestinal barrier injury development are briefly explored, as well as natural flavonoids having CVD-protective actions on the intestinal barrier. In addition, natural flavonoids with myocardial protective effects were docked with ZO-1 targets to find natural products with higher activity. These natural flavonoids can improve intestinal mechanical barrier function through anti-oxidant or anti-inflammatory mechanism, and then prevent the occurrence and development of CVDs.
Insights
Natural flavonoids protect against cardiovascular diseases (CVDs) by strengthening the intestinal barrier. They reduce oxidative stress and inflammation, improving gut health to prevent CVDs.
Area of Science:
- Pharmacology
- Cardiovascular Medicine
- Gastroenterology
Background:
- Cardiovascular diseases (CVDs) are often linked to intestinal barrier damage.
- The protective mechanisms of natural flavonoids against this damage are not fully understood.
Purpose of the Study:
- To review current research on natural flavonoids in mitigating CVDs via intestinal barrier protection.
- To emphasize their role in maintaining intestinal epithelial barrier integrity.
Main Methods:
- Review of studies on natural flavonoids and intestinal barrier function.
- Analysis of mechanisms including oxidative stress, inflammatory cytokines, and tight junction proteins.
- Molecular docking of flavonoids with ZO-1 targets to identify potent compounds.
Main Results:
- Natural flavonoids inhibit oxidative stress and regulate inflammatory cytokine expression.
- They enhance the expression of tight junction proteins, improving intestinal barrier integrity.
