What is Non steroidal aromatase inhibitors?

Non-Steroidal Aromatase Inhibitors are one of two categories of aromatase inhibitors. AIs are divided into two categories, steroidal aromatase inhibitors and non-steroidal aromatase inhibitors that is based on their mechanism of action and structure. NSAIs are mainly used to treat breast cancer in women. NSAIs binding is a reversible process where NSAIs binds to the aromatase enzyme through non-covalent interactions. When aromatase inhibitors are used to treat breast cancer the main target is the aromatase enzyme which is responsible for the high estrogen level.
