Nitromethaqualone[1] is an analogue of methaqualone that has similar sedative and hypnotic properties.[2] It is significantly more potent (10x) compared to the parent compound; the typical dose is approximately 25 mg.[3] However, the aromatic nitro group is metabolised to the corresponding aniline, which proved to be a mutagen.[3] As a consequence, nitromethaqualone was not developed further due to toxicity concerns.
