Inhibitor 51 was further investigated in competitive ABPP: at 0.1 μM, 51 inhibited ABHD11 in all tested proteomes (mouse whole brainmembranes, prostate cancer cell lysates, and mitochondrial fractionof brown fat and testicle), but at higher concentrations (1–10μM) it also inhibited FAAH. This evidence concerns the gene FAAH and Familial prostate cancer.
