Z-VRPR-FMK (TFA) (VRPR) is a tetrapeptide and a selective and irreversible inhibitor of lymphoma translocation protein 1 (MALT1) in mucosa-associated lymphoid tissue.
Irreversible MALT1 inhibitor. Suppresses T cell activation-induced cleavage of Bcl-10 in a dose-dependent manor. Reduces Jurkat cell adhesion to fibronectin. Cell permeable.
Geranylgeranoic acid (GGA) is an isoprenoid that has been found inS. chinensisand has anticancer activity.1It induces apoptosis in Huh7 and PLC/PRF/5 human hepatoma cells and MLE-10 transformed mouse hepatocytes, but not primary mouse hepatocytes, when used at concentrations ranging from 1 to 20 μM. GGA (10 μM) induces apoptosis in Huh7 cellsvialoss of the mitochondrial membrane potential and activation of interleukin-1β-converting enzyme (ICE) and cysteine protease precursor 32 (CPP32).2It also inhibits lysine-specific demethylase 1 (LSD1; IC50= 46.97 μM).3 1.Shidoji, Y., and Ogawa, H.Natural occurrence of cancer-preventive geranylgeranoic acid in medicinal herbsJ.
