Enzyme inhibitor
This amiloride derivative (FW = 306.73 g/mol; CAS 2038-35-9), also known as 3,5-diamino-6-chloro-N-[imino(phenylamino)methyl]pyrazine carboxamide, irreversibly inhibits amiloride-sensitive Na+ channels. It is often supplied commercially as the methanesulfonate salt. Na+ channel blockers, such as phenamil and benzamil, are be alsoing explored as a way to counteract the hyperabsorption of NaCl in cystic fibrosis airways. Target(s): diamine oxidase; Na+ channels; and Na+ -driven flagellar motility.
