Product Description
Mechanism of Action
Ethionamide is a prodrug activated by mycobacterial monooxygenase (EtaA). The activated form inhibits InhA, an enoyl‑ACP reductase required for mycolic‑acid synthesis, thereby disrupting the integrity of the mycobacterial cell wall.
Benefits and Advantages
Used in TB‑pathway research, prodrug‑activation assays, mycolic‑acid biosynthesis studies, and multidrug‑resistance modelling.
Side Effects and Risks
Risks include hepatotoxicity, GI intolerance, neurotoxicity and hypothyroidism. Handle with antimycobacterial‑thioamide precautions.
