2-bromolysergic acid diethylamide

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].

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.
