| 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

| LDH is a general term that refers to the enzyme that catalyzes the interconversion of lactate and pyruvate. LDH is a tetrameric enzyme, meaning it is composed of four subunits. LDH refers to the enzyme as a whole, while LDHA specifically refers to the M subunit. Elevated LDHA levels are often associated with poor prognosis and aggressive tumor behavior, similar to elevated LDH levels. leakage of LDH is a well-known indicator of cell membrane integrity and cell viability [35]. LDH leakage results from the breakdown of the plasma membrane and alterations in membrane permeability, and is widely used as a cytotoxicity endpoint. However, it's worth noting that some studies have shown that LDHA is a more specific and sensitive biomarker for cancer than total LDH, as it is more closely associated with the Warburg effect and cancer metabolism. Dysregulated LDH activity contributes significantly to cancer development, promoting the Warburg effect (Chen et al., 2007), which involves increased glucose uptake and lactate production, even in the presence of oxygen, to meet the energy demands of rapidly proliferating cancer cells (Warburg and Minami, 1923; Dai et al., 2016b). LDHA overexpression favors pyruvate to lactate conversion, leading to tumor microenvironment acidification and aiding cancer progression and metastasis. Inhibitors: Flavonoids, a group of polyphenols abundant in fruit, vegetables, and medicinal plants, function as LDH inhibitors.
