2-Aminoquinoline (2-Quinolinamine) is a promising compound as bioavailable nNOS inhibitor but suffers from low human nNOS inhibition, low selectivity versus human eNOS, and significant binding to other CNS targets. 2-Aminoquinoline exhibits antiviral activity against the vaccinia virus. 2-Aminoquinoline has the potential for the research of antineurodegenerative agents.
