| Auranofin — an orally administered gold(I) coordination complex (gold–phosphine–thiolate “thiosugar” drug) originally approved as a disease-modifying antirheumatic drug (DMARD) for rheumatoid arthritis and widely studied for repurposing as a redox-targeted anticancer and anti-infective agent. It is a small-molecule metallodrug whose pharmacology is typically tracked via blood/plasma gold concentrations because intact auranofin is rapidly transformed and not reliably detected in blood. Standard abbreviation(s): AF (auranofin); primary target shorthand: TrxR/TxNRD (thioredoxin reductase). Primary mechanisms (ranked):
Bioavailability / PK relevance: Oral absorption is incomplete; clinical PK is commonly described as ~25% of the gold content absorbed. Gold is highly protein-bound and exhibits prolonged retention/long terminal half-life, so effective exposure depends strongly on dose and dosing duration. Because “gold levels” are the main measurable surrogate, cross-study comparisons should specify matrix (whole blood vs plasma) and timing (steady-state vs short course). In-vitro vs systemic exposure relevance: Many oncology cell studies use ~0.5–5 µM AF. Human short-course data at 6 mg/day for 7 days report plasma gold on the order of ~0.1–0.3 µg/mL (roughly sub-µM to ~1–1.5 µM range when expressed as gold equivalents), meaning lower in-vitro ranges can overlap clinically observed exposure surrogates, while higher µM regimens may exceed typical oral exposures unless higher doses/longer courses or formulation changes are used. Clinical evidence status: Approved for rheumatoid arthritis (historical DMARD use) but oncology use remains investigational. Multiple early-phase repurposing trials exist across hematologic and solid tumors; several completed studies have limited publicly posted outcomes, and there is no established standard-of-care anticancer indication. Pathways: 1.Thioredoxin Reductase (TrxR) Inhibition. - Most widely recognized for potently inhibiting TrxR. 2.Induction of Reactive Oxygen Species (ROS) and Oxidative Stress. 3.MMP depolarization, release of cytochrome c 4.Endoplasmic Reticulum (ER) Stress and Unfolded Protein Response (UPR) 5.Inhibition of Pro-survival Pathways (e.g., NF-κB Signaling) -ic50 for cancer typically 1-3uM, normal cell 5-10uM or higher. -Several studies animal testing antitumor efficacy have used doses in the region of 5–8 mg/kg via intraperitoneal injection or oral administration. -Auranofin’s anticancer activity is often linked to its inhibition of thioredoxin reductase, leading to increased oxidative stress.

| Normal cells grow and divide in a regulated manner through the cell cycle, which consists of phases (G1, S, G2, and M). Cancer cells often bypass these regulatory mechanisms, leading to uncontrolled proliferation. This can result from mutations in genes that control the cell cycle, such as oncogenes (which promote cell division) and tumor suppressor genes (which inhibit cell division). |
