Adamantane and protoadamantanealkanamines as potential anti-Parkinson agents.

The synthesis of 2-halo-1-adamantanemethanamines, 4-protoadamantanemethanamines, and 4-protoadamantaneamines is described. The anti-Parkinson activity of these amines in terms of reversal of reserpine-induced catalepsy in rats has been evaluated and compared with amantadine. 2-Bromo- and 2-chloro-1-adamantanemethanamines are shown to be twice as active as amantadine.
