pharmacodynamic properties of drugs in current use. Nitricoxide (NO) is a molecular messenger involved in a number of physiological processes in mammals. It is synthesised by nitricoxide synthase (NOS) from L-arginine and its overproduction could lead to a number of neurological disorders. The aim of this study was to synthesise a series of novel indazole, indole and other fluorescent derivatives conjugated

A series of fluorescent heterocyclic adamantane amines were synthesised with the goal to develop novel fluorescent ligands for neurological assay development. These derivatives demonstrated multifunctional neuroprotective activity through inhibition of the N-methyl-D-aspartate receptor/ion channel, calcium channels and the enzyme nitric oxide synthase. It also exhibited a high degree of free radical scavenging potential. N-(1-adamantyl)-2-oxo-chromene-3-carboxamide (8), N-adamantan-1-yl-5-dimethyl-amino-1-naphthalenesulfonic acid (11) and N-(1-cyano-2H-isoindol-2-yl) adamantan-1-amine (12) were found to possess a high degree of multifunctionality with favourable physical-chemical properties for bioavailability and blood-brain barrier permeability. The ability of these heterocyclic adamantane amine derivatives as nitric oxide synthase inhibitors, calcium channel modulators, NMDAR inhibitors and effective antioxidants, indicate that they may find application as multifunctional drugs in neuroprotection.
