  <class>SmallMolecule</class>
  <description>Ethionamide belongs to the pyridines and derivatives, a class of organoheterocyclic compounds within the organic compounds. This compound has the chemical formula C8H10N2S and an average molecular weight of 166.24 g/mol.

Ethionamide is found in or released from ten recorded sources. Within healthcare, pharmaceuticals, and veterinary products, it is utilized as a drug for the treatment of tuberculosis. Other recorded sources include indoor air via air, dust, and atmospheric transport; the preparation of malt within food, food processing, and cookware; household cleaning and consumer products such as pipe accessories, ash trays, and other smoking requisites; and electrical and electronic equipment, specifically communication cables or conductors, power cables, antennas, and video games. Exposure to the compound occurs through oral and inhalation routes.

At the molecular level, ethionamide interacts with three recorded protein targets. It acts as an inhibitor or otherwise affects catalase-peroxidase (katG), enoyl-[acyl-carrier-protein] reductase [NADH] (inhA), and nuclear factor erythroid 2-related factor 2 (NFE2L2).</description>
