Lycopodium clavatumspores に由来する薬理学的に重要な生物活性成分であるリコポジンは、p53 活性を調節することなく、5-リポキシゲナーゼを調節し、難治性前立腺癌細胞のミトコンドリア膜電位を脱分極することによってアポトーシスを引き起こします。リコポジンは、カスパーゼ 3 活性化によるアポトーシスの誘導により、HeLa 細胞の増殖を阻害します。

Lycopodine, a pharmacologically important bioactive component derived from Lycopodium clavatumspores, triggers apoptosis by modulating 5-lipoxygenase, and depolarizing mitochondrial membrane potential in refractory prostate cancer cells without modulating p53 activity[1]. Lycopodine inhibits proliferation of HeLa cells through induction of apoptosis via caspase-3 activation[2]. Caspase-3
Lycopodine (5.22-78.3 μg/mL; 12 hours) has 50% viability at 57.62±0.086 μg/mL and 51.46±1.43 μg/mL for PC3 and LnCaP, respectively[1].Treated with Lycopodine (74-222 mM; 12 hours), the apoptotic index is with respect to the gradual increase in doses for the PC3 and LnCaP cells[1].Lycopodine (74-222 mM; 12 hours) induces cell cycle arrest at G0/G1 phase in PC3 and LnCaP cells[1].Lycopodine (0-200 µg/mL; 48 hours) shows cytotoxicity to HeLa cells in a dose and time dependent manner. However, Lycopodine shows minimal cytotoxic effects in normal peripheral blood mononuclear cells (PBMC) even at the highest dose (200 µg/mL)[2].Lycopodine (100, 200 µg/mL; 24 hours) increases level of Bax and decreases the mitochondrial cytochrome c. This is followed by an increase in expression of cytochrome c in cytosolic fraction. Lycopodine also cleaves the caspase-3 in the total cell lysate, while the expression of Bcl-2 is down regulated[2]. Cell Viability Assay[1] Cell Line: PC3 and LnCaP cells
