ABC34 is an inactive control probe for JJH260 , the inhibitor of androgen-induced gene 1 (AIG1), an enzyme that hydrolyzes fatty acid esters of hydroxy fatty acids (FAHFAs). ABC34 demonstrates an IC50 value greater than 25 μM for the inhibition of 9-PAHSA but is more potent in blocking the serine hydrolase ABHD6 and the palmitoyl-protein hydrolase PPT1, which are both off-targets of JJH260.
