New 5-hydroxyadamantan-2-one derivatives with heteroaromatic, aromatic, and aliphatic acids (nicotinic, succinic, p-chlorophenoxyacetic, 3,4,5-trimethoxybenzoic, and anisic) were synthesized. Their pharmacological properties were studied to discover compounds with cerebrovascular anti-ischemic activity and without hypotensive activity. Esters of succinic acid and 5-hydroxyadamantan-2-one (diester Ia and monoester Ib, 100 mg/kg, i.v.) exhibited the most potent effect on cerebral circulation under ischemic conditions. They did not lower arterial blood pressure. The monoester was less toxic with LD50 740.0 (676.0 – 804.0) mg/kg. Analysis of the cerebrovascular effects of the succinate esters of 5-hydroxyadamantan-2-one using bicuculline revealed a GABA-ergic mechanism of action on cerebral vessels. However, radioligand analysis in vitro using the specific ligand [3H]-SR 95531 found that these esters did not compete for rat-brain membrane GABAA-receptors. Thus, the monoester of succinic acid and 5-hydroxyadamantan-2-one possessed pronounced cerebrovascular anti-ischemic activity and did not produce hypotensive effects. The latter circumstance differentiated it from well-known drugs used in neurology (picamilon, Mexidol, nimodipine, cinnarizine, and Cavinton).
