Chemical structure of URB754

URB754 was originally reported to be a potent, noncompetitive inhibitor of monoacylglycerol lipase.[1] However, recent studies have shown that URB754 failed to inhibit recombinant MGL, and brain FAAH activity was also resistant to URB754.[2] Some controversy in the field remains regarding the use of this compound.
