2-methyl-4-aminobenzoic acid

Description:

2-Methyl-4-aminobenzoic acid, also known as p-aminobenzoic acid (PABA) derivative, is an aromatic carboxylic acid characterized by the presence of both an amino group (-NH2) and a carboxylic acid group (-COOH) on a benzene ring. The molecular structure features a methyl group (-CH3) attached to the benzene ring at the second position and an amino group at the fourth position, contributing to its unique properties. This compound is typically a white to off-white crystalline solid, soluble in water and organic solvents, which makes it useful in various applications. It is known for its role in the synthesis of folic acid and as a potential UV filter in sunscreens due to its ability to absorb ultraviolet light. Additionally, 2-methyl-4-aminobenzoic acid exhibits mild antibacterial properties and is sometimes used in pharmaceuticals and cosmetics. Its chemical behavior is influenced by the functional groups present, allowing it to participate in various chemical reactions, including acylation and amidation.

4-Amino-2-methylbenzoic acid

CAS: 2486-75-1

4-Amino-2-methylbenzoic acid is a low molecular weight compound that has been shown to inhibit the neuraminidase enzyme. It interacts with the imine group of the enzyme and forms a covalent bond, which prevents the release of sialic acid from the terminal sugar residue of glycoproteins. The inhibition of this enzyme leads to decreased bacterial growth. 4-Amino-2-methylbenzoic acid has been shown to be active against Gram positive bacteria such as Staphylococcus aureus and Streptococcus pneumoniae, but not against Gram negative bacteria such as Escherichia coli or Pseudomonas aeruginosa. This compound is also able to inhibit the synthesis of c-reactive protein (CRP) in human erythrocytes.
