# Centaurin **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/centaurin **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-19 **Evidence Score:** 4 / 10 **Category:** Compound **Also Known As:** ADAP1, ArfGAP, ADP-ribosylation factor GTPase-activating protein, Centaurin-alpha, CENT-α1, Arf-GAP with dual PH domains ## Overview Centaurin is a flavone compound that modulates centaurin-α1 protein expression, potentially affecting neuro[inflammatory pathway](/ingredients/condition/inflammation)s. Research suggests it may influence [cognitive function](/ingredients/condition/cognitive) and autoimmune responses in the central nervous system through GTPase-activating protein regulation. ## Health Benefits • May protect against Alzheimer's disease progression - deletion of centaurin-α1 improved cognitive function in J20 transgenic mouse models (preliminary evidence only) • Could reduce neuro[inflammation](/ingredients/condition/inflammation) - centaurin-α1 deficient mice showed partial resistance to experimental autoimmune encephalomyelitis (animal studies only) • Supports healthy dendritic development - overexpression increased dendritic terminal tips and length in cultured neurons (cell culture evidence) • May regulate synaptic function - links amyloid-beta to synaptic dysfunction through Ras-Elk-1 signaling pathway (mechanistic studies only) • Potential [neuroprotective effect](/ingredients/condition/cognitive)s - modulates astrocytic activation and dendritic spine abnormalities (preclinical models only) ## Mechanism of Action Centaurin appears to work by modulating centaurin-α1 protein expression, which functions as a GTPase-activating protein in neuronal signaling pathways. The deletion or reduction of centaurin-α1 may alter Arf family GTPase activity, potentially reducing neuro[inflammatory](/ingredients/condition/inflammation) responses and improving synaptic function. This mechanism involves the regulation of vesicular trafficking and membrane dynamics in neural cells. ## Clinical Summary Current evidence for centaurin is limited to preliminary animal studies using transgenic mouse models. Research on J20 transgenic mice showed improved [cognitive function](/ingredients/condition/cognitive) when centaurin-α1 was deleted, suggesting potential benefits for Alzheimer's disease progression. Additional studies in centaurin-α1 deficient mice demonstrated partial resistance to experimental autoimmune encephalomyelitis, indicating possible neuro[inflammatory](/ingredients/condition/inflammation) protection. No human clinical trials or safety data are currently available for centaurin supplementation. ## Nutritional Profile Centaurin is not a nutrient, food, or dietary supplement — it is a family of intracellular signaling proteins (also known as centaurin-alpha, ADAP1/centaurin-α1, and related isoforms) that function as ArfGAPs (ADP-ribosylation factor GTPase-activating proteins) and phosphatidylinositol 3,4,5-trisphosphate (PIP3) binding proteins endogenously expressed in mammalian tissues, particularly enriched in brain neurons. As an endogenous protein, it has no conventional nutritional profile — no macronutrient, micronutrient, vitamin, mineral, or fiber content applies. It is not consumed as a food or supplement. Bioactive context: Centaurin-α1 (ADAP1) contains a zinc-finger ArfGAP domain and a pleckstrin homology (PH) domain with high-affinity binding for PIP3 (Kd ~50 nM). It modulates Arf6-dependent membrane trafficking, dendritic branching, and synaptic plasticity. Centaurin-α2 (CENTG1/AGAP1) and centaurin-γ (AGAP2/PIKE) are related family members with distinct domain architectures. These proteins are not bioavailable via oral ingestion and cannot be obtained through diet. No known food source, dietary precursor, or supplemental form exists. Any referenced biological effects (neuroprotection, [anti-inflammatory](/ingredients/condition/inflammation) activity) derive from genetic modulation studies in animal models, not from exogenous administration or nutritional intake. ## Dosage & Preparation No clinically studied dosage ranges exist as centaurin has never been tested in humans as a therapeutic or supplement. Current research uses genetic knockout models or cellular overexpression rather than administered doses. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Safety data for centaurin supplementation is not available due to lack of human studies. The compound's effects on GTPase signaling pathways suggest potential interactions with medications affecting neurological function or immune responses. Given the preliminary nature of research and unknown effects on human physiology, centaurin should be avoided during pregnancy and breastfeeding. Individuals with neurological conditions or those taking immunosuppressive medications should consult healthcare providers before considering use. ## Scientific Research No human clinical trials, RCTs, or meta-analyses exist for centaurin as a therapeutic agent or supplement. All available evidence comes from preclinical research using animal models (J20 transgenic mice) and cell culture systems, with no PubMed PMIDs for human trials available. ## Historical & Cultural Context Centaurins have no documented history in traditional medicine systems as they are endogenous mammalian proteins only recently identified through modern molecular biology techniques. They are not plant-derived substances and have never been used traditionally. ## Synergistic Combinations Not applicable - centaurin is not a supplement ingredient ## Frequently Asked Questions ### What is centaurin and how does it work? Centaurin is a flavone that modulates centaurin-α1 protein expression, affecting GTPase-activating pathways in neurons. It may reduce neuroinflammation and improve cognitive function by altering vesicular trafficking and membrane dynamics in neural cells. ### Can centaurin help with Alzheimer's disease? Preliminary mouse studies suggest centaurin may benefit Alzheimer's disease by improving cognitive function in J20 transgenic models. However, this evidence is extremely limited and no human trials have been conducted to confirm these effects. ### What are the side effects of centaurin? Side effects of centaurin are unknown as no human safety studies exist. Given its effects on neurological pathways, potential risks may include interactions with brain function and immune responses, requiring medical supervision. ### Is centaurin available as a supplement? Centaurin is not widely available as a commercial supplement due to limited research and lack of safety data. Most available information comes from laboratory studies rather than supplement formulations. ### How much centaurin should I take daily? No established dosage exists for centaurin as human clinical trials have not been conducted. Without safety and efficacy data, dosing recommendations cannot be made and medical consultation is essential before use. ### What does current clinical research show about centaurin's effectiveness in humans? Most evidence for centaurin comes from animal studies, particularly mouse models of Alzheimer's disease and neuroinflammation, where centaurin-α1 deletion showed cognitive benefits. Clinical trials in humans are limited, and robust peer-reviewed human data is not yet widely available. This means centaurin remains largely in the research phase, and health claims should be treated as preliminary until larger human studies are completed. ### Is centaurin safe for children or elderly individuals? Safety data specific to children and elderly populations is not well-established, as most research has focused on animal models rather than human trials across different age groups. Elderly individuals with neurodegenerative conditions and children should consult a healthcare provider before use, as age-related differences in metabolism and medication interactions are not fully characterized. Without clinical safety studies, supplementation in these vulnerable groups should only proceed under medical supervision. ### How does centaurin compare to other neuroprotective supplements like NAD+ boosters or curcumin? Centaurin targets neuroinflammation and dendritic development through distinct mechanisms, whereas NAD+ boosters work on cellular energy metabolism and curcumin functions as an antioxidant with broader anti-inflammatory effects. Direct comparative studies between centaurin and these alternatives in humans do not yet exist. Choosing between them depends on individual health goals and the strength of evidence, with centaurin currently having the weakest human clinical data of the three. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
