Nitric oxide (NO) is a powerful and ubiquitous molecule, being produced by several cell types throughout our bodies and is an important signaling molecule as well as a key component of the innate and adaptive immune systems.  Studies have demonstrated that NO acts as an antiviral, antimicrobial, anti-thrombotic, and vasodilatory agent.  

NOTA is focused on developing novel NO delivery systems and applications that mimic our own body's NO uses for treating and preventing a wide variety of life-threatening illnesses and conditions.

 

What nitric oxide (NO) does

Nitric Oxide is widely found throughout nature in both the plant and animal kingdoms.  Human evolution has resulted in our body’s production of nitric oxide (NO) as a major component of our immune systems and as a messaging molecule throughout the body. Previously known by scientists as an air pollutant, NO’s production by a wide variety of cells in our bodies was only discovered in the early 1990’s with the discovery in human physiology leading to a Nobel Prize in 1998.

Why does this small molecule play such a big and diverse role? NO’s broad range of applications can be attributed to the molecule’s high reactivity and transient nature which causes its direct action to be highly localized and yet can be stabilized as a nitrosothiol and thus able to be transported throughout the body.   As part of the immune systems it’s able to treat viral infection by inhibiting viral replication, attack microbes, affect vasodilation to decrease hypertension, and treat viral infection by inhibiting viral replication. 

Nitric oxide is a potent vasodilator, making it ideal for the treatment of hypertension.  iNO is FDA approved for treatment of neonates with pulmonary hypertension. Studies have shown that the administration of iNO during lung transplantation can prevent primary graft failure (PGF), improve oxygenation, and reduce pulmonary hypertension. Due to its antiseptic properties, iNO has been proposed as a treatment for chronic airway infections, especially in diseases like CF, sinusitis, tuberculosis, and COPD where airway infections are common. When added to the sweep gas during open heart surgery and other extracorporeal circulation [ECC] applications, as it has been shown to prevent both thrombosis and systemic inflammatory response syndrome by preventing platelet and white blood cell activation. iNO is a promising candidate for treatment across a variety of applications.
