Thiocarlide
（重定向自Isoxyl）
Thiocarlide (or tiocarlide or isoxyl) is a thiourea drug used in the treatment of tuberculosis, inhibiting synthesis of oleic acid and tuberculostearic acid.
Thiocarlide has considerable antimycobacterial activity in vitro and is effective against multi-drug resistant strains of Mycobacterium tuberculosis. Isoxyl inhibits M. bovis with six hours of exposure, which is similar to isoniazid and ethionamide, two other prominent anti-TB drugs. Unlike these two drugs, however, isoxyl also partially inhibits the synthesis of fatty acids.
