The present study was carried out to investigate the possibility that bispidinone derivative makes anticancer drug availability to human cervical carcinoma cell. The B8 has the lowest IC50 value among B8, B9 and B10 which are bispidinone analogue with bromide. According to cytotoxic test through WST-8 assay, B8 shows the most magnificent cytotoxicity effectiveness with 76 μM of IC50 value. In human cervical carcinoma cell treated with B8, it noticeably controlled cellular multiplication by increase of concentration and time. Furthermore, morphological changes like cellular shrink, disruption and nuclear condensation, feature of apoptosis, are observed. Annexin V-FITC/PI double staining assay test proved that B8 can cause apoptosis. Moreover, after treatment with 76 μM of B8, flow cytometry analysis shows that increase of active oxygen species are induced and membrane potential in mitochondria is decreased. Manifestation of Bcl-2 family and caspase cascades protein provides evidence that B8 induces apoptosis through mitochondria and caspase-related pathway. Taken together, we suggested that B8 reduced membrane potential in mitochondria and induce apoptosis through the pathway depended on mitochondria and caspase.
