Chlorahololide D is a natural lindane-type sesquiterpene dimer and selective potassium channel blocker that stimulates reactive oxygen species ROS levels to cause cell cycle arrest in the G2 phase, modulates Bcl-2 and Bax and FAK, thereby inhibiting MCF-7 cell growth and triggering apoptosis. Chlorahololide D inhibits tumor proliferation, migration and angiogenesis in in vivo experiments and has anti-breast cancer potential.

| 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.[1] 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).[2] |
| 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.[2] 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.[2] |
