FAAH and prostate carcinoma: 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.
