Sakuranetin

Sakuranetin is a flavanone compound primarily found in cherry fruits that exhibits antimicrobial and antifungal properties. This flavonoid works by disrupting fungal cell wall synthesis and inhibiting microbial enzyme systems in preliminary laboratory studies.

Origin & History

Sakuranetin is a flavanone phytoalexin (C₁₆H₁₄O₅) naturally occurring in cherry trees (Prunus serrulata) and rice plants (Oryza sativa), where it functions as an antifungal and antimicrobial defense compound. It is extracted from plant sources using organic solvents like methanol or ethanol, yielding a yellow crystalline powder.

Historical & Cultural Context

No historical or traditional medicinal uses are documented for sakuranetin. It is primarily recognized as a plant defense compound rather than a traditional remedy for human use.

Health Benefits

• Antifungal activity demonstrated in plant studies (preliminary evidence only)
• Antimicrobial properties against plant pathogens (in vitro evidence)
• Potential anti-inflammatory effects noted in cherry flavonoid contexts (preliminary evidence)
• Possible antioxidative properties as part of flavonoid class (theoretical based on structure)
• May interact with Helicobacter pylori adenosine receptor A3 (computational modeling only)

How It Works

Sakuranetin disrupts fungal cell wall synthesis by inhibiting chitin synthase and β-1,3-glucan synthase enzymes. The compound also interferes with microbial cytoplasmic membrane integrity and inhibits key metabolic enzymes in pathogenic organisms. Its antioxidant activity stems from its ability to scavenge free radicals and chelate metal ions through its hydroxyl groups.

Scientific Research

No human clinical trials, randomized controlled trials, or meta-analyses have been conducted on sakuranetin. Current research is limited to in vitro and plant-based studies focusing on its antifungal activity as a phytoalexin, with no PubMed PMIDs available for human trials.

Clinical Summary

Current research on sakuranetin is limited to in vitro laboratory studies and plant pathology research. Studies have demonstrated antifungal efficacy against Candida species and plant pathogens like Botrytis cinerea at concentrations of 50-200 μg/mL. No human clinical trials have been conducted to establish therapeutic dosages or clinical benefits. Evidence for anti-inflammatory and antioxidant effects remains preliminary and derived from general flavonoid research rather than sakuranetin-specific studies.

Nutritional Profile

Sakuranetin is a pure flavonoid compound (specifically a flavanone/methoxyflavonoid), not a whole food, so it contains no macronutrients (0g protein, 0g fat, 0g carbohydrates), no dietary fiber, no vitamins, and no minerals in isolation. Molecular formula: C16H14O5, molecular weight: 286.28 g/mol. It is the 7-O-methyl ether derivative of naringenin, distinguished by a methoxy group at the 7-position and a hydroxyl group at the 4'-position of the B-ring. Found naturally in black cherry (Prunus serotina), rice (Oryza sativa) as a phytoalexin, and Baccharis species at trace concentrations typically in the microgram-per-gram range in plant tissue (approximately 0.1–50 µg/g dry weight depending on species and stress conditions). As a lipophilic flavanone due to its methyl ether group, bioavailability is theoretically higher than its parent compound naringenin in terms of membrane permeability, though intestinal absorption data in humans is essentially absent. It is not metabolically classified as a nutrient; its relevance is pharmacological rather than nutritional. No established dietary reference intake, no caloric contribution, and no known essential physiological role in human nutrition has been documented.

Preparation & Dosage

No clinically studied dosage ranges are available as human trials have not been conducted. Sakuranetin remains an experimental compound without established dosing protocols. Consult a healthcare provider before starting any new supplement.

Safety & Interactions

Safety data for sakuranetin supplementation in humans is not available due to lack of clinical studies. As a flavonoid compound, it may theoretically interact with medications metabolized by cytochrome P450 enzymes, though specific interactions have not been documented. Pregnant and breastfeeding women should avoid supplementation due to insufficient safety data. Individuals with known allergies to cherry products or flavonoids should exercise caution.
