Chlorahololide D

SKU: orb1681393

Description

Chlorahololide D is a lindane-type sesquiterpene dimer and selective potassium channel blocker. It induces G2/M cell cycle arrest and apoptosis in MCF-7 breast cancer cells by elevating ROS and modulating Bcl-2/Bax/FAK pathways, demonstrating anti-proliferative, anti-migratory, and anti-angiogenic activity in vivo.

Bioactivity

• Target IC50:
  Rat dissociated hippocampal neurons:2.7±0.3μM|MCF-7 cells:6.7 μM|HepG2 cells:13.7 μM
• In Vivo:
  In MCF-7 xenograft zebrafish models, Chlorahololide D (2.5–10 μM) significantly reduced tumor fluorescence intensity and the number of metastatic foci. In transgenic zebrafish models, Chlorahololide D disrupted the formation of intersegmental vessels (ISVs) and dorsal longitudinal anastomotic vessels (DLAVs) in a dose-dependent manner (5–20 μM), indicating strong anti-angiogenic activity.
• In Vitro:
  Chlorahololides D exhibited potent and selective potassium channel blocking activity on the delayed rectifier (IK) K+ current in rat dissociated hippocampal neurons, with the IC50 values of 2.7±0.3μM. Chlorahololide D exhibited potent cytotoxicity against MCF-7 breast cancer cells with an IC₅₀ of 6.7 μM, and moderate activity against HepG2 liver cancer cells (IC₅₀ = 13.7 μM).
