Alpha-Mangostin | STING agonist (human)

α-Mangostin (6147-11-1) is a xanthone natural product that has historically been used in traditional folk medicine.1 It is a potent agonist of human STING (Stimulator of Interferon Genes) and also weakly activates mouse STING.2 Induces IFN-β production and repolarizes human monocyte-derived M2 macrophages to M1. Improves insulin secretion and protects INS-1 cells from streptozotocin-induced damage.3 Suppresses the metastasis of human renal carcinoma cells.4 Synergizes with kinase inhibitors in suppression of proliferation of SK-MEL-2 malignant melanoma cells.5
