garcinol

Garcinol 是一种从印度藤黄提取的聚异戊二烯基二苯甲酮，对乙酰胆碱酯酶和丁酰胆碱酯酶具有抗胆碱酯酶的特性，IC50分别为 0.66 µM 和 7.39 µM。它还抑制组蛋白乙酰转移酶和 p300 CPB 相关因子，具有抗炎和抗癌活性。

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.

7-epi-Isogarcinol 是一种PPAP（多环聚异戊二烯酰基间苯三酚），显示出适度的抗增殖活性。它通过阻断STAT3信号通路，诱导apoptosis（细胞凋亡）并抑制细胞迁移作用。
