Summary
Nitrite, once viewed negatively, is now recognized as a vital molecule. It acts as a life-saving drug, releasing nitric oxide (NO) to aid circulation and potentially treat cardiovascular disease.
Area of Science:
- Biochemistry
- Physiology
- Pharmacology
Background:
- Nitrite is a naturally occurring nitrogen compound essential for life.
- Historically, nitrite was considered harmful due to nitrosamine formation.
- Recent research reveals nitrite's critical role in nitric oxide (NO) biology.
Purpose of the Study:
- To review the historical and recent evolution of nitrite's role in biology.
- To explore nitrite's metabolism and its function as a biomarker.
- To discuss nitrite's potential as a therapeutic agent for cardiovascular diseases.
Main Methods:
- Literature review encompassing historical perspectives and recent scientific findings.
- Analysis of nitrite's compartment-specific metabolism.
- Evaluation of nitrite's role in NO homeostasis and gene expression regulation.
Main Results:
- Nitrite's pharmacological perception has shifted from harmful to beneficial.
- Nitrite is a key player in NO homeostasis, particularly during hypoxia.
- Nitrite functions as an endogenous signaling molecule and regulator of gene expression.
Conclusions:
- Nitrite is a fundamental molecule with significant biological and therapeutic implications.
- Reevaluation of nitrite's metabolism and function is warranted.
- Nitrite holds promise as a diagnostic marker and therapeutic agent for cardiovascular disease.

01:28Nitric Oxide Signaling Pathway
Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure to...
01:202° Amines to N-Nitrosamines: Reaction with NaNO2
Secondary amines react with nitrous acid to form N-nitrosamines, as depicted in Figure 1. Nitrous acid, a weak and unstable acid, is formed in situ from an aqueous solution of sodium nitrite and strong acids, such as hydrochloric acid or sulfuric acid, in cold conditions. In the presence of an acid, the nitrous acid gets protonated. The subsequent loss of water results in the formation of the electrophile known as nitrosonium ion.
01:22Inorganic Nitrogen Assimilation
Nitrogen is an essential element in biological systems, forming a crucial component of proteins, nucleic acids, and other cellular constituents. Many bacteria and archaea acquire nitrogen in the form of nitrate (NO₃⁻) or ammonia (NH₃), which are then assimilated into biomolecules through specific enzymatic pathways.Assimilatory Nitrate ReductionWhen nitrate enters the cell, it undergoes a two-step reduction process known as assimilatory nitrate reduction. Initially, the enzyme nitrate reductase...
01:16Antianginal Drugs: Nitrates and β-Blockers
In cardiovascular health, antianginal drugs combat angina pectoris — a condition marked by chest pain owing to diminished blood flow to the heart.
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...

01:23Antihypertensive Drugs: Vasodilators
Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...
01:20Overview of Nitrogen Metabolism
Nitrogen is a very important element for life because it is a major constituent of proteins and nucleic acids. It is a macronutrient, and in nature, it is recycled from organic compounds and stored in the form of ammonia, ammonium ions, nitrate, nitrite, or nitrogen gas by many metabolic processes. Many of these metabolic processes are carried out only by prokaryotes.
