[Safety Profile]

Poison by intraperitoneal and intravenous routes. Experimental teratogenic and reproductive effects. Human systemic effects by ingestion: ddation of the arteries or veins. Many lysergic acid derivatives have central nervous system effects. When heated to decomposition it emits very toxic fumes such as Brand NOx. See other lysergic acid derivatives.

[Uses]

2-Bromo-LSD (BOL-148; Bromolysergide) is a Dopamine Receptor antagonist that directly affects dopamine neurons in the substantia nigra neostriatum. 2-Bromo-LSD increases the hydroxylation of tyrosine in striatum and antagonizes the decrease of Apomorphine-induced DOPA accumulation. 2-Bromo-LSD also blocks the 5-HT Receptor mediated DOPA formation[1].
[in vivo]

2-Bromo-LSD (0.125-5.5mg/kg; i.p.; single dose) increases the in vivo tyrosine hydroxylation in the striatum of Male Sprague-Dawley rats, and increase the accumulation of DOPA with minimum effect dose of 0.125 mg/kg[1].
