Certain novel compounds having the structural formulan where R₂, R₃ and R₄ are each selected from the group consisting of H and OA; A is H or is selected from the group consisting of hydrocarbyl radicals, e.g. lower alkyl radicals, i.e. methyl, ethyl, propyl, etc., orn wherein R₅ is selected from the group consisting of hydrocarbyl radicals, e.g. alkyl and aromatic residues; n is 2 or 3; and R₁ is selected from the group consisting of organic radicals having fused aromatic rings, that is, radicals comprising at least two rings that share a pair of carbon atoms or share a carbon and nitrogen atom are useful for inducing a dopaminergic response and reducing the intraocular pressure in a mammal. |
