Gallein（Cat No.:I010697） is a compound that functions as an inhibitor of G protein βγ (Gβγ) subunit signaling. It disrupts the interaction between Gβγ subunits and PI3Kγ, a signaling protein involved in cell growth and survival. Due to its ability to inhibit Gβγ signaling, gallein exhibits antitumor activity, making it a potential candidate for cancer treatment. Interestingly, gallein also finds application as a red dye, an acid-base indicator, and a detection reagent for phosphate in various laboratory settings.
