WWL 154 is an serine hydrolase (SH) and fatty acid amide hydrolase FAAH-4 inhibitor.

Beta-Sitosterol (SKF 14463) has recently been shown to induce G2/M arrest, endoreduplication, and apoptosis through the Bcl-2 and PI3K/Akt signaling pathways. Beta-Sitosterol (SKF 14463) , a main dietary phytosterol found in plants, may have the potential for prevention and therapy for human cancer. Although the exact mechanism of action of Beta-Sitosterol (SKF 14463) is unknown, it may be related to cholesterol metabolism or anti-inflammatory effects (via interference with prostaglandin metabolism). Beta-Sitosterol (SKF 14463) induces apoptosis and activates key caspases in MDA-MB-231 human breast cancer cells.

Endothelial lipase inhibitor-1 is a potent inhibitor of endothelial lipase with an IC50 of 49 nM.

JJKK 048 is a potent and selective MAGL inhibitor.

Dual FAAH/sEH-IN-1 is a dual inhibitor of sEH (soluble epoxide hydrolase) (IC50: 9.6 nM) and FAAH (fatty acid amide hydrolase) (IC50: 7 nM) with high affinity and anti-inflammatory activity.

KT182 is a selective and  potent inhibitor of α/β-hydrolase domain containing 6 (ABHD6), with an IC50 of 0.24 nM in Neuro2A cells.

KML29 is highly selective and effective monoacylglycerol lipase (MAGL) inhibitor. It has effective inhibition of human/mouse/rat MAGL (IC50: 5.9/15/43 nM). It has not inhibitory for FAAH (IC50 > 50 μM). It also effectively and selectively blocks hydrolysis of 2-arachidonoylglycerol (2-AG) in mice (IC50: 2.5 nM, 2-AG; >50 μM, AEA).

Atglistatin is a highly effective, specific and competitive ATGL inhibitor with an IC50 of ~0.7 μM for inhibition of lipolysis in vitro, and no toxicity when the concentration up to 50 μM.
