Nitrogen source

A nitrogen source refers to any chemical compound or element that an organism utilizes to obtain the nitrogen necessary for the synthesis of essential biological molecules, including amino acids, proteins, and nucleic acids (1). In human physiology, the primary nitrogen sources are dietary proteins and amino acids, while microorganisms and plants may utilize inorganic forms such as ammonia, nitrates, or atmospheric nitrogen (2). In the context of drug discovery, 'Nitrogen source' is considered a general nutritional category rather than a specific therapeutic target like a receptor or enzyme (3). While specific pathways involving nitrogen metabolism—such as glutaminolysis in cancer cells—are frequently targeted by drugs like glutaminase inhibitors, the broad term 'Nitrogen source' is too non-specific to be classified as a singular molecular target (4,5).
