Abstract

Temu kunci (Boesenbergia pandurata) rhizome showed cytotoxic effect against T47D breast cancer cell line. It contains Panduratin, a chalcone compund, that has been investigated as chemopreventive agent. The exploration of extract of temu kuci as chemopreventive agent was expected to be an alternative for cancer therapy. The aim of this research was to determine the cytotoxic activities of ethanolic extract of temu kunci against HeLa cervix cancer and WiDr colon cancer cell line. The cytotoxic activities of ethanolic extract of temu kunci were tested using MTT assay against HeLa and WiDr cells. The IC50 values were obtained using linier regression equation. The ethanolic extract of temu kunci showed cytotoxic activities on HeLa cervix cancer and WiDr colon cancer cell lines with IC50 at 87 µg/mL and 76 µg/mL, respectively. Low IC50 values (<100 µg/mL) showed that ethanolic extract of temu kunci is potential to be developed as chemoprevention agent on cervix cancer and colon cancer. However, its molecular mecahanism need to be explored.

Abstract

Eugenia uniflora Lam. is one of herbal products developed for anticancer. The aim of the present study was to identify the antiproliferative effect of ethanolic extract of Eugenia Uniflora Lam. leaves (EEU) on breast cancer cell line T47D. This Research was initiated by extracting the active contents of Eugenia uniflora Lam. leaves by maceration with ethanol 96%. The extract was then analyzed by thin layer chromatography (TLC). Cytotoxic assay of EEU was carried out by using MTT assay. Apoptosis phenomenon was observed with double staining using acridine orange-ethidium bromide. EEU showed cytotoxic effct on T47D cells with IC50 value of 65 μg/ml. Moreover, EEU 50 μg/ml and 100 μg/ml induced apoptosis. TLC examination showed that EEU used in this study contain phenolic, flavonoid, and saponin compounds which were suggested to be responsible for antiproliferative effect. Further molecular mechanism underlying EEU antiproliferative effect needs to be done.Keywords : Eugenia uniflora Lam., T47D cells, antiproliferative, apoptosis

Abstract

Doxorubicin, primary chemoteurapeutic agent used for breast cancer treatment, is known to have various side effects included multi drug resistance 9MDR) phenomenon. Therefore, exploration of co-chemotherapeutic agent is important to be conducted in order to prevent MDR. Secang (Caesalpinia sappan L.) which contains active compounds brazilin and brazilein, is proven to have activity as anticancer. The aim of this study is to determine the potency of Caesalpinia sappan L.ethanolic extract (CEE) as co-chemotherapeutic agent of doxorubicin and its mechanism through apoptosis induction on T47D breast cancer cells. Caesalpinia sappan L. heartwood powder was macerated with ethanol 70%. The cytotoxic effect of CEE alone and its combination with doxorubicin was analyzed using MTT assay. Apoptosis assay was done by flowcytometry-annexin V method. CEE showed cytotoxic activity on T47D cells with IC50 value of 35 μg/ml, while combinatorial test showed that all of combination doses of CEE and doxorubicin gave synergistic effect. Flowcytometry-annexin V assay proved that treatment of CEE induced apoptosis of doxorubicin. Based on these results, we conclude that Caesalpinia sappan L. heartwood ethanolic extract is potential to be developed as co-chemotherapeutic agent of doxorubicin.Keywords : Caesalpinia sappan L., doxorubicib, apoptosis, T47D cells.

Abstract

Resistance  to  chemotherapy  is  believed  to  cause  treatment  failure  of  the  patient cancer. Secang (Caesalpinia sappan L.) has been proven to possess anticancer activity on some cancer cell lines. The aimed of this study to develop ethanolic extract of secang wood (EES) as  chemosensitizing  agent  through  apoptotic  induction  on  breast  cancer  MCF-7  cells. Extraction  of  secang  was  done  by  using  maceration  with  70  %  ethanol.  Single  and combinatorial treatment of EES and doxorubicin on MCF-7 breast cancer cells were analyzed by using MTT assay to determine the IC50 value and combination index (CI) to evaluate the combinatorial effect. Apoptosis was analyzed with flowcytometry (annexin V).  EES showed a dose-dependent cytotoxicity (IC50 value of 37 µg/ml), while combinatorial treatment showed that  7  concentrations  was  found  to  be  synergist  with  doxorubicin  on  MCF-7  cells. Combinatorial treatment also triggered apoptotic instead of single treatment. Based on this result,  we  conclude  that  ethanolic  extract  of  secang  wood  is  potential  as  chemosensitizing agent in breast cancer.Keyword: Caesalpinia sappan L, MCF-7 cells, doxorubicin, apoptosis.
