2-Pyrazinecarboxylic acid

Description:

2-Pyrazinecarboxylic acid, also known as pyridine-2-carboxylic acid, is an aromatic heterocyclic compound characterized by a pyrazine ring with a carboxylic acid functional group at the second position. Its molecular formula is C6H6N2O2, and it features a six-membered ring containing two nitrogen atoms. This compound is typically a white to light yellow crystalline solid that is soluble in water and organic solvents, reflecting its polar nature due to the carboxylic acid group. 2-Pyrazinecarboxylic acid exhibits acidic properties, allowing it to participate in various chemical reactions, including esterification and amidation. It is often used in the synthesis of pharmaceuticals, agrochemicals, and as a building block in organic chemistry. Additionally, it can act as a ligand in coordination chemistry due to the presence of nitrogen atoms, which can coordinate with metal ions. Its derivatives may exhibit biological activity, making it of interest in medicinal chemistry. Safety data should be consulted for handling and exposure guidelines, as with all chemical substances.

Pyrazine-2-carboxylic acid

CAS: 98-97-5

Pyrazine-2-carboxylic acid is a potent inhibitor of bacterial x-lactamase. It was found that the inhibition of x-lactamase by pyrazine-2-carboxylic acid could be attributed to hydrogen bonding interactions with the active site of the enzyme and a high rate constant for the reaction. The antibacterial efficacy of pyrazine-2-carboxylic acid against wild type Streptococcus pneumoniae and methicillin resistant Staphylococcus aureus (MRSA) was tested and found to be comparable to that of benzylpenicillin. Pyrazine-2-carboxylic acid also has biological properties, such as an inhibitory effect on protein synthesis in bacteria, which may be due to its ability to bind to ribosomes.
