Paris saponin VII (Chonglou Saponin VII) 是从延龄草 (Trillium tschonoskii Maxim) 的根和根茎中分离的甾体皂苷。Paris saponin VII 诱导的 K562/ADR 细胞凋亡与 Akt/p38 MAPK 和 P-gp 的抑制有关。Paris saponin VII 减弱线粒体膜电位，增加凋亡相关蛋白 (如 Bax 和细胞色素 c) 的表达，并降低 Bcl-2，caspase-9，caspase-3，PARP-1 和 p-Akt 的蛋白表达水平。Paris saponin VII 在 K562/ADR 细胞中诱导强烈的自噬，为白血病治疗提供生化基础。

Background:

Paris saponin VII (Chonglou Saponin VII) is a steroidal saponin isolated from the roots and rhizomes of Trillium tschonoskii Maxim. Paris saponin VII-induced apoptosis in K562/ADR cells is associated with Akt/MAPK and the inhibition of P-gp. Paris saponin VII attenuates mitochondrial membrane potential, increases the expression of apoptosis-related proteins, such as Bax and cytochrome c, and decreases the protein expression levels of Bcl-2, caspase-9, caspase-3, PARP-1, and p-Akt. Paris saponin VII induces a robust autophagy in K562/ADR cells and provides a biochemical basis in the treatment of leukemia[1]. Akt p38 Bcl-2 Caspase-9 Caspase-3 PARP-1

Paris saponin VII (Chonglou Saponin VII) inhibits the growth of adriamycin-resistant human leukemia cells (K562/ADR) in a dose-dependent manner. Paris saponin VII significantly suppresses cell proliferation by cell cycle arrest in the G0/G1 phase[1].

Paris saponin VII (Chonglou Saponin VII) (intravenous administration) significantly enhances anticancer efficacy of adriamycin to MCF-7/ADR xenograft model in nude mice[2].
