Key Takeaway
Note that natural bioactive compounds in sepsis require SAR-guided optimization due to poor druggability and narrow therapeutic windows.
This narrative review evaluates the potential of natural bioactive compounds, specifically flavonoids, terpenoids, alkaloids, and quinones, in the context of sepsis. The scope encompasses a broad range of biological mechanisms rather than a specific clinical trial population or intervention dose. The authors discuss how pharmacokinetic stability, blood-brain barrier penetrability, and intracellular target affinity are dictated by specific structural features such as functional group substitutions, spatial ring conformations, and quaternary ammonium charge states.
The review outlines potential multi-organ protective effects spanning the lungs, kidneys, heart, liver, intestines, and brain. These effects are described as occurring through modulation of the NF-κB/NLRP3 inflammatory axis, the Nrf2/HO-1 antioxidant system, and the AMPK/mTOR immunometabolic circuit. Additionally, the authors note that natural products have demonstrated the ability to inhibit macrophage M1 polarization, block neutrophil extracellular trap formation, ameliorate mitochondrial bioenergetic crises, and alleviate sepsis-associated encephalopathy.
Despite these mechanistic arguments, the authors explicitly identify critical limitations including poor druggability, unstable pharmacokinetics, and narrow therapeutic windows. No adverse events or serious adverse events were reported in this narrative synthesis. The authors conclude that future research must transition from empirical screening to SAR-guided lead optimization, integrating advanced nano-delivery systems and biomarker-driven precision clinical trials to address these gaps.

BackgroundSepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Despite significant advancements in modern life-support technologies, the mortality rate of sepsis and its associated complications in the intensive care unit (ICU) remains unacceptably high.ProblemThe repeated clinical failure of traditional single-target therapies (e.g., anti-endotoxin agents) underscores an urgent need for systemic therapeutic strategies capable of simultaneously restoring the immune, metabolic, and coagulation networks.MethodsThis comprehensive narrative review evaluates the pharmacological mechanisms of natural bioactive compounds in mitigating sepsis-associated organ dysfunction. Unlike previous descriptive reviews, we categorize active compounds based on their core chemical scaffolds (flavonoids, terpenoids, alkaloids, and quinones) and provide a rigorous comparative analysis of their structure-activity relationships (SAR).ResultsEvidence reveals that specific structural features—such as functional group substitutions, spatial ring conformations, and quaternary ammonium charge states—directly dictate the pharmacokinetic stability, blood-brain barrier (BBB) penetrability, and intracellular target affinity of these natural products. By leveraging these structural advantages, natural products exert multi-organ protective effects (spanning the lungs, kidneys, heart, liver, intestines, and brain) through the synergistic modulation of three converging hubs: the NF-κB/NLRP3 inflammatory axis, the Nrf2/HO-1 antioxidant system, and the AMPK/mTOR immunometabolic circuit. Specifically, they demonstrate profound efficacy in inhibiting macrophage M1 polarization, blocking neutrophil extracellular trap (NET) formation, ameliorating mitochondrial bioenergetic crises, and alleviating sepsis-associated encephalopathy (SAE).ConclusionAlthough natural products offer profound multi-target advantages, their clinical translation is frequently hindered by poor druggability, unstable pharmacokinetics, and narrow therapeutic windows. Future research must decisively transition from empirical screening to SAR-guided lead optimization, integrating advanced nano-delivery systems and biomarker-driven precision clinical trials to successfully advance these natural scaffolds into clinical applications.
