Isovaleramide is an organic compound with the formula (CH3)2CHCH2C(O)NH2. The amide derived from isovaleric acid, it is a colourless solid.

Occurrence and biological activity

Isovaleramide is a constituent of valerian root.

In humans, it acts as a mild anxiolytic at lower doses and as a mild sedative at higher dosages.[1] Isovaleramide has been shown to be non-cytotoxic and does not act as a CNS stimulant. It inhibits the liver alcohol dehydrogenases and has a reported LD50 of greater than 400 mg/kg when administered intraperitoneally in mice.[2]

It is a positive allosteric modulator of the GABAA receptor, similarly to isovaleric acid. [3]
