Nitric Oxide (NO) is a molecule of extreme interest to biologists, pharmacologists, physiologists,
and biochemists, characterized as a mediator in the cardiovascular system. It has been found
to be implicated in various pathological processes. NO is synthesized enzymatically by Nitric Oxide
Synthases (NOSs) from L-arginine, and therefore NOSs have emerged as very crucial therapeutic targets.
Herein, a series of extracts from plants as well as a number of isolated compounds acting as NOS
inhibitors are presented.
Keywords: Nitric oxide synthase inhibitors, naturally occurring NOS inhibitors, NOS inhibitors from plants, isolated natural
compounds, extracts from plants.
