Thiram has been reported to inhibit dopamine-beta-hydroxylase (D beta H), thereby affecting norepinephrine (NE) synthesis.

Inhibition experiments with dopamine beta-hydroxylase purified from chicken adrenals indicated that thiram, ziram, and ferbam are potent competitive inhibitors with the substrate the substrate ascorbate.

As one biochemical indicator of the toxicity, dopamine-beta-hydroxylase is inhibited in the brain.
It appeared that ferbam, maneb, nabam, zineb, disulfiram, thiram and ethylene thiourea did not change significantly D2-receptor binding at doses which were already overtly toxic.
