6-Hydroxydopamine hydrobromide (6-OHDA hydrobromide) is a catecholaminergic neurotoxin that has been used to induce dopaminergic lesions and parkinsonian symptoms as a model of Parkinson's disease in rodents[1]. 

6-OHDA hydrobromide (75 μM) activates caspase-3, -8, and -9 in a time-dependent manner and increases the level of intracellular reactive oxygen species (ROS) in PC12 cells and induces apoptosis in rat substantia nigra when stereotaxically injected into the right MFB[2]. 

6-OHDA hydrobromide induces locomotor impairment in mice and loss of tyrosine hydroxylase-reactive neurons in mouse brain when administered into the substantia nigra, medial forebrain bundle (MFB), or striatum at doses of 9, 6, and 18 μg, respectively[3].
