CAS 771-81-3: 5-Pyrimidinecarboxylic acid, 4-amino-2-(methylthio)-

4-Amino-2-(methylthio)pyrimidine-5-carboxylic acid (4AMP) is a molecule that inhibits protein kinase. It does this by binding to the ATP site of the enzyme, preventing ATP from binding and thus inhibiting the phosphorylation of proteins. 4AMP has been shown to inhibit the activity of various protein kinases including cAMP-dependent protein kinase, tyrosine kinase, and serine/threonine kinases. 4AMP is also an acidic functional group that can be used in organic chemistry as a nucleophile or electrophile. This compound can be dissolved in vacuo or in solvents such as methanol, acetone, dichloromethane, and ethanol.
