The compounds according to the invention can therefore be used as dopaminergic agents, e.g. in the treatment of Parkinson's disease.
Furthermore, the compounds according to the invention effect a decrease on the intra-ocular pressure in rabbits, at concentrations of 10 to 100 ~M. Hale rabbits of ca. 2'k kg are fixed in cages leaving their heads free. The solutions with the compound to be tested are applied to the right eye and the placebo solutions to the left eye (2 drops each, i.e. ca. 40 ~l). The eyes are firstly anaesthetized with a solution containing Novesine (0.4 %) and Fluorescein (0.05 %) and the ocular pressure is determined at various intervals after administration tlO, 20, 30, 60, 90, 120, 180 and 240 minutes), whereby an applanation tonometer according to Goldberg is used.

The compounds according to the invention are therefore useful in the treatment of glaucoma.
The ccmpounds according to the invention also show activity in the behavioural despair test [R.D. Porsolt et al., Arch. Int. Pharmaco-dyn., 229, 327 - 336 (1977)] upon administering doses of 10 to 100 mg/kg p.o.

The compounds according to the invention may therefore be used in the prevention, reduction or treatment of dependency (or for treatment after deprivation to avoid renewed dependency) arising from the abuse of cocaine.
For these therapeutical activities, an indicated daily dosage lies in the range ca. 1 to 100 mg, especially ca. 10 to 80 mg, of the compound according to the invention, which is conveniently administered e.g. in part doses up to 4 times daily.
The compounds according to the invention may be administered in any usual manner, e.g. orally, for example in the form of tablets or capsules, or parenterally, for example in the form of injection solutions or suspensions.
For the treatment of glaucoma, the compounds according to the invention are preferably applied topically to the eye in ca. 0.002 to ca. 0.02 % ophthalmological solutions.
