Sanguiin H-6

Sanguiin H-6 is an ellagitannin compound that inhibits osteoclast formation by blocking nuclear translocation of NFATc1, c-Fos, and NF-κB transcription factors. This polyphenolic compound demonstrates anti-resorptive effects in bone metabolism studies.

Origin & History

Sanguiin H-6 is a hydrolyzable tannin, naturally occurring in plants like Rubus idaeus (raspberry) and Rubus medius. It is a complex polyphenol with a molecular formula of C₈₂H₅₄O₅₂, isolated from plant sources.

Historical & Cultural Context

No specific historical or traditional medicinal uses for Sanguiin H-6 are documented in the research. It remains primarily studied in modern scientific contexts.

Health Benefits

• Inhibits osteoclastogenesis by blocking nuclear translocation of NFATc1, c-Fos, and NF-κB, as shown in in-vitro studies [4]. • Reduces multinucleated osteoclast formation in bone marrow macrophages and RAW-D cells [4]. • Decreases TRAP-positive osteoclasts in cell assays [4]. • Demonstrates potential cytotoxicity above certain concentrations, indicating a need for careful dosage [4]. • Lacks comprehensive human clinical evidence, indicating preliminary findings [4].

How It Works

Sanguiin H-6 blocks nuclear translocation of key osteoclastogenic transcription factors including NFATc1, c-Fos, and NF-κB. This inhibition prevents the differentiation of bone marrow macrophages and RAW-D cells into multinucleated osteoclasts. The compound specifically reduces TRAP-positive osteoclast formation, disrupting the bone resorption cascade at the cellular level.

Scientific Research

No human clinical trials or meta-analyses are available for Sanguiin H-6. Current research is limited to in-vitro studies focusing on its effects on osteoclastogenesis in cell models [4].

Clinical Summary

Current evidence for sanguiin H-6 comes exclusively from in-vitro studies examining osteoclast formation. Research has focused on bone marrow macrophages and RAW-D cell cultures, demonstrating significant reduction in multinucleated osteoclast formation and TRAP-positive cell counts. No human clinical trials or animal studies have been published to date. The evidence base remains limited to cellular mechanisms without dosage recommendations or bioavailability data.

Nutritional Profile

Sanguiin H-6 is not a nutrient but a high-molecular-weight ellagitannin (a type of hydrolyzable polyphenolic tannin) with a molecular formula of C82H54O52 and a molecular weight of approximately 1871 g/mol. It is one of the principal bioactive polyphenolic compounds found in raspberries (Rubus idaeus), strawberries (Fragaria × ananassa), and other Rubus species. Key details: • Classification: Dimeric ellagitannin, formed from two units of casuarictin linked via a dehydrodigalloyl (valoneoyl) group. • Concentration in food sources: Found at concentrations of approximately 172–805 mg/100 g dry weight in red raspberry fruit, making it the dominant ellagitannin in raspberries; also present in strawberry fruit at lower concentrations (roughly 15–80 mg/100 g dry weight depending on cultivar and extraction method). • Bioactive properties: Polyphenolic compound with documented antioxidant, anti-inflammatory, and anti-osteoclastogenic activities; it is not a source of macronutrients (protein, fat, carbohydrate), vitamins, or minerals. • Bioavailability: Oral bioavailability is considered very low due to its large molecular size and susceptibility to hydrolysis in the gastrointestinal tract. In the gut, sanguiin H-6 is partially hydrolyzed to release ellagic acid, which is further metabolized by colonic microbiota into urolithins (primarily urolithin A and urolithin B), the forms that are actually absorbed systemically. Intact sanguiin H-6 is largely undetectable in plasma after oral consumption. Therefore, its systemic biological effects are believed to be mediated primarily through its gut-derived metabolites (urolithins) rather than the parent compound. • No appreciable caloric, vitamin, mineral, or fiber contribution as an isolated compound. • Solubility: Soluble in aqueous-organic solvent mixtures (e.g., methanol-water, acetone-water); limited solubility in pure water at physiological pH.

Preparation & Dosage

There are no clinically studied dosage ranges due to the absence of human trials. In vitro studies used 5 μM to 50 μM concentrations, noting cytotoxicity above 25-50 μM. Consult a healthcare provider before starting any new supplement.

Synergy & Pairings

Curcumin, Resveratrol, Quercetin, Omega-3 fatty acids, Vitamin D

Safety & Interactions

No safety data exists for sanguiin H-6 as human studies have not been conducted. As an ellagitannin, it may theoretically interact with iron absorption and certain medications metabolized by cytochrome P450 enzymes. Pregnancy and lactation safety is unknown due to lack of research. Individuals with bleeding disorders should exercise caution as tannins may affect platelet function.
