H-Tyr(3-I)-OH (3-Iodo-L-tyrosine) is an inhibitor of tyrosine hydroxylase (Ki = 0.39 M) and an intermediate in the synthesis of thyroid hormones

Twenty mice were infused with H-Tyr(3-I)-OH into the dorsal striata.?Mice were anesthetized with ketamine (50 mg/kg IP) and xylazine (5mg/kg IP,) and placed in a David Kopf stereotaxic apparatus.?Vehicle and H-Tyr(3-I)-OH solution (0, 1 and 10μM H-Tyr(3-I)-OH dissolved in 0.9% NaCl with 0.001% acetic acid) was slowly injected (5 μl volume) with a blunted 30-gauge cannula at the following coordinates of the left dorsal striata with respect to bregma: AP= +0.86, L= +1.6, and V= -3.5 mm.
