Synthesis

Furonazide was first prepared in 1955 by Miyatake from isoniazid and 2-Acetylfuran by refluxing in ethanol, followed by filtration of the crystalline product.[1][2]

Applications

Furonazide has shown bacteriostatic action and is tuberculostatic at levels of 10−8 molar.[1] The in vitro antibacterial activity of furonazide against Bacillus Calmette-Guerin was found to be essentially equal to that of isoniazid on an equimolar basis.[3] In vivo studies in the guinea pig showed furonazide slightly more active than isoniazid as a tuberculostatic agent.[4] The drug has relatively low toxicity. The median lethal dose (LD50, rat oral) was reported as 2,600 mg/kg.[5]
