Isogarcinol is a natural polyisoprenylated benzophenone first isolated from plant species in the genus Garcinia. It has immunosuppressant actions, inhibiting the protein phosphatase calcineurin (IC50 = 36 μM) and suppressing the proliferation of T cells. Oral administration of isogarcinol in mice decreases delayed type hypersensitivity, prolongs graft survival in allogeneic skin transplants, suppresses inflammation in collagen-induced arthritis, and reduces clinical symptoms in experimental autoimmune encephalomyelitis. Isogarcinol inhibits the proliferation of HL-60 and PC-3 cancer cells (IC50s = 4 and 8 μg/ml, respectively) through cell cycle arrest and apoptosis.
2-hydroxy-4-methoxybenzophenone-D5是2-hydroxy-4-methoxybenzophenone (T0499)的氘代化合物。2-hydroxy-4-methoxybenzophenone的CAS号为131-57-7。Oxybenzone是晒黑和皮肤保护剂中常用的紫外线过滤剂。它是二苯甲酮的衍生物,用作破坏内分泌的化学物质,可穿透胎盘和血脑屏障。它损害自噬,改变表观遗传状态并破坏凋亡神经元细胞中的类维生素 X 受体信号传导。
