Antiapoptotic Activity Of Methyl (3r,4e,6z,15e)-3-Hydroxyoctadecatrienoate In Human Cervical Carcinoma Hela Cells

Inhibitors of thapsigargin-induced cell death in human cervical carcinoma HeLa cells were screened among the metabolites of marine organisms. The MeOH extract of the cyanobacterium Rivularia sp. was found to exhibit inhibitory activity. Column chromatography purification was used to isolate methyl (3R,4E,6Z,15E)-3-hydroxyoctadecatrienoate (MHO) as the active compound. MHO was determined to inhibit apoptotic stimuli-induced cell death in HeLa cells.
