1 Low doses (50 and 80 mg/kg) of benserazide (Ro4-4602), an aromatic amino acid decarboxylase inhibitor, markedly reduced 5-hydroxytryptamine and melatonin in the rat pineal gland without affecting hypothalamic 5-hydroxytryptamine. 2 This differential effect shows that inhibition of the pineal gland decarboxylase activity is possible, and confirms that the rat pineal gland is accessible to peripherally acting agents.
