N-(2-Phenethyl)benzamide
CAS:N-(2-Phenethyl)benzamide (NPEB) is a molecule that belongs to the group of reactive molecules. It has been shown to be toxic to gram-positive bacteria, such as Staphylococcus aureus and Bacillus subtilis, but not gram-negative bacteria such as Escherichia coli. NPEB also has been shown to have locomotor activity in animals, which may be due to its ability to inhibit the mitochondrial electron transport chain and inhibit ATP production. NPEB's biological properties are well characterized. FTIR spectroscopy showed that this molecule has an amide functional group and is a small molecule with a molecular weight of 176.4 g/mol.
