| Ajoene is a compound found in garlic, specifically in the oil extracted from crushed garlic cloves. It has been studied for its potential anti-cancer properties. Research suggests that ajoene may have several mechanisms by which it can inhibit the growth of cancer cells and induce apoptosis (cell death). Ajoene — an organosulfur secondary metabolite formed from garlic (Allium sativum) after crushing/processing (an allicin-derived transformation product; typically present as E/Z isomers). It is a thiol-reactive small molecule (vinyl-disulfide sulfoxide motif) studied mainly as a cytotoxic/anti-migratory agent in cancer models and as a topical antifungal. Classification: small-molecule natural product (garlic organosulfur compound). Abbreviation(s): none universally standard; often specified as E-ajoene / Z-ajoene. Primary mechanisms (ranked):
Bioavailability / PK relevance: Systemic human PK is poorly defined; ajoene is typically discussed as an allicin-derived downstream product and allicin itself is not detected in human serum after raw garlic ingestion in classic studies. Practical translation in oncology is therefore most credible for local/topical exposure or for optimized analogues; oral dietary exposure may not reproduce common in-vitro micromolar conditions reliably. In-vitro vs systemic exposure relevance: Many anticancer studies use ~low–tens of µM in vitro; whether these levels are achievable systemically from diet/supplements is uncertain. Topical delivery can reach higher local concentrations (e.g., skin lesions/fungal infections), and small human topical studies exist. Clinical evidence status: Predominantly preclinical (cell culture and animal models). Small human topical evidence exists for basal cell carcinoma tumor shrinkage and for fungal skin infections (e.g., tinea pedis; chromoblastomycosis). No robust systemic oncology RCT evidence. Approximate ajoene content values for different parts of the garlic plant:Garlic bulbs: 1-5 mg of ajoene per clove Garlic scapes (green shoots): 0.5-2 mg of ajoene per 100g Garlic chives (leaves): 0.5-2 mg of ajoene per 100g Garlic microgreens: 1-5 mg of ajoene per 100g μM concentrations of ajoene that have been reported to exhibit biological activity: Antimicrobial activity: 1-10 μM Antioxidant activity: 1-50 μM Anti-inflammatory activity: 5-20 μM Anticancer activity: 10-50 μM Cardiovascular health: 5-20 μM Approximate unverified μM concentrations of ajoene that can be achieved with different amounts of garlic or garlic chives: 1 clove of garlic (3g): approximately 1-5 μM of ajoene 1 tablespoon of minced garlic (15g): approximately 5-15 μM of ajoene 1 cup of chopped garlic (100g): approximately 30-60 μM of ajoene 1 tablespoon of chopped garlic chives (15g): approximately 0.5-2 μM of ajoene 1 cup of chopped garlic chives (100g): approximately 5-10 μM of ajoene 1 ounce (28g) of garlic microgreens: approximately 10-30 μM of ajoene 1 cup of garlic microgreens (100g): approximately 30-60 μM of ajoene 1 ounce (28g) of garlic chive microgreens: approximately 5-15 μM of ajoene 1 cup of garlic chive microgreens (100g): approximately 15-30 μM of ajoene Ajoene — mechanistic axes relevant to oncology translation

| H2O2 is a reactive oxygen species (ROS) that can induce oxidative stress in cells. While low levels of ROS can promote cell signaling and proliferation, high levels can lead to DNA damage, apoptosis (programmed cell death), and other cellular dysfunctions. This dual role means that H2O2 can contribute to cancer development and progression, as oxidative stress can lead to mutations and genomic instability. H2O2 can enhance the effectiveness of certain chemotherapeutic agents by increasing oxidative stress in cancer cells. Additionally, localized delivery of H2O2 has been explored as a means to selectively target and kill cancer cells while sparing normal cells. Cancer cells often exhibit altered metabolism, leading to increased production of reactive oxygen species, including H2O2. This can result from enhanced mitochondrial activity, increased glycolysis, or other metabolic adaptations that are characteristic of cancer. Reported H2O2 concentrations for representative compounds.
Note: many products at lower concentrations act as antioxidants, instead of Prooxidants. Generally, increased hydrogen peroxide and oxidative stress are associated with poor outcomes, while the specific context and cellular environment can modulate its effects. |
