Mining biologically-active molecules for inhibitors of fatty acid amide hydrolase (FAAH): identification of phenmedipham and amperozide as FAAH inhibitors.

摘要

The screening of known medicinal agents against new biological targets has been shown to be a valuable approach for revealing new pharmacology of marketed compounds. Recently, carbamate, urea and ketone inhibitors of fatty acid amide hydrolase (FAAH) have been described as promising treatments for pain, anxiety, depression and other CNS-related conditions. In order to find novel FAAH inhibitors, a focused screen of molecules containing potentially reactive moieties or having in vivo effects that are possibly relevant to the biology of FAAH was conducted. These studies revealed phenmedipham 13 and amperozide 14 to be inhibitors of human FAAH, with an IC(50) of 377 nM and 1.34 microM, respectively.
