Background: Rosuvastatine, doxazosin, repaglinide and oxcarbazepin are therapeutic drugs available in the market for the treatment of different diseases. Potential to display antitumor activities has also been suggested. The aim of the current study was to evaluate their in vitro effects on some human transformed cell lines. Materials and Methods: Cytotoxicity of the four drugs was tested in MCF-7, HeLa and HepG2 cells by the neutral red assay method and also the effect of rosuvastatine and doxazosin against Ehrlich Ascities Carcinoma Cells (EACC) by trypan blue assay. Results: Rosuvastatine exerted the greatest cytotoxic effect against HepG2 cells with an $IC_{50}$ value of $58.7{\pm}69.3$; in contrast doxazosin showed least activity with $IC_{50}=104.4{\pm}115.7$. Repaglinide inhibited the growth of both HepG2 and HeLa cells with $IC_{50}$ values of $87.6{\pm}117.5$ and $89.3{\pm}119.5$, respectively. Oxcarbazepine showed a potent cytotoxicity against both HeLa ($IC_{50}=19.4{\pm}43.9$) and MCF7 cancer cells (($IC_{50}=22{\pm}35.7$).On the other hand the growth of EACC was completely inhibited by doxazosine (100% inhibition) while rosuvastatine had weak inhibitory activity (11.6%). Conclusions: The four tested drugs may have cytotoxic effects against hepatic, breast and cervical carcinoma cells; also doxazosine may inhibit the growth of endometrial cancer cells. Further investigations in animals are needed to confirm these results.

노화억제, 항균, cholesterol 저하작용 등 다양한 생리활성을 가지고, 기관지염, 천식 등 호흡기 질환에도 옛부터 효과가 있는 것으로 알려져 있으며 식품으로 애용되고 있는 적채를 metanol (BOM)로 먼저 추출하고 이를 hexane 분획물(BOMH), ethyl ether 분획물(BOMEE), ethyl acetate 분획물(BOMEA), butanol 분획물(BOMB) 및 물 분획물(BOMA) 등 다섯가지의 각 용매별로 분획하여 적채의 항균, 암세포 증식 억제 및 QR유도 효과를 연구하였다. 먼저 적채의 각 분획물을 Streptococcus mutans, Bacillus subtilis, Escherichia coli. Pseudomonas aeruginosa 및 Aspergil-lus oryzae의 5가지 균주에 첨가시료농도를 증가시키면서 첨가하였다. 즉, 각 분획 별 시료를 500, 1000, 1500 및 2000 $\mu{g}$/ml의 농도로 사용균주에 각각 처리하였을때 BOMEA에서 비교적 높은 항균 활성 효과를 나타내었고, 그 다음으로는 BOMEE이었다. 적채의 암세포 증식억제 효과(cytotoxicity)를 MTT assay 로 실험한 결과, 3종의 암세포주 HepG2, HeLa 및 MCF-7은 모두 BOMEE에서 높은 암세포 증식억제 효과를 보였으며, HepG2 세포주를 이용한 암예방 QR 유도 활성은 다른 분획층에 비해 비극성 용매층인 BOMH과 BOMEE에서 유의적으로 QR유도 활성을 증가시키는 것으로 나타났다. 이 결과를 기초로 독특한 보라색을 띄며 식탁에서 널리 애용되고 있는 자주색 대표식품인 적채의 항균 및 암세포 성장저지 및 QR 유도 효과를 일으키는 생리활성 물질의 존재와 기전 규명에 유익한 자료가 될 것으로 사료된다.

Adverse side-effects and lack of scientific validation of some chemotherapeutic agents prevent the use of many traditional medicines claimed to have anti-cancer effects. Ethanolic extract of Conium maculatum has long been used in traditional and alternative systems of medicine including homeopathy for the treatment of glandular enlargements, cancerous tumours or hard lumps of testicles, prostate, ovaries, breasts and/ or uterus, particularly in the breast. However, if and how it acts still remains scientifically unknown. This study aims to test if Conium extract (CE), used as mother tincture of Conium in homeopathy, has demonstrable anti-cancer potentials without having much cytotoxicity in normal cells. Cytotoxicity of the drug was tested by conducting MTT assay on both normal (peripheral blood mononuclear cells) and HeLa cells. We also evaluated DNA fragmentation and DNA damage by DAPI and diphenylamine assay. The LDH activity assay was done to evaluate the percentages of apoptosis and necrosis. ROS accumulation also was evaluated to pin-point the actual events of apoptosis. Administration of drug clearly demonstrated its anti-cancer potentials as evidenced by the DNA damage analysis. The ROS activity also increased in case of the CE treated cells. LDH data revealed that the mode of cell death was mainly apoptotic and not necrotic. CE appears to induce apoptosis of cancer cells through ROS mediated pathway, and has negligible cytotoxicity against normal cells.

In this study, phytochemicals present in Propolis Extract (PE) were employed as reducing and stabilizing reagents to synthesize silver nanoparticles. Three propolis-reduced silver nanoparticles (P-AgNPs1-3) were synthesized using increasing amounts of PE. P-AgNPs were treated with different cancer cells-lung (A549), cervix (HeLa) and colon (WiDr) - for 24, 48 and 72 h to evaluate their anti-proliferative activities. A non-cancerous cell type (L929) was also used to test whether suppressive effects of P-AgNPs on cancer cell proliferation were due to a general cytotoxic effect. The characterization results showed that the bioactive contents in propolis successfully induced particle formation. As the amount of PE increased, the particle size decreased; however, the size distribution range expanded. The antioxidant capacity of the particles increased with increased propolis amounts. P-AgNP1 exhibited almost equal inhibitory effects across all cancer cell types; however, P-AgNP2 was more effective on HeLa cells. P-AgNPs3 showed greater inhibitory effects in almost all cancer cells compared to other NPs and pure propolis. Consequently, the biological effects of P-AgNPs were highly dependent on PE amount, NP concentration, and cell type. These results suggest that AgNPs synthesized utilizing propolis phytochemicals might serve as anti-cancer agents, providing greater efficacy against cancer cells.

이 연구에서는 살아있는 질편모충의 단백질녈해효소가 인체 면역글로불린을 분해하는지 알아보고 질편모충에 의한 조직세포 독성에 있어서 단백질분해효소의 역할을 시험관내에서 관찰하였다 실험에 사용한 질편모충은 질염환자로년터 분리한 KT9 분리주이었으며 세포독성을 알아보기 위한 표적세포로는 HeLa 세포를 사용하였다 질편모충 단백질분해효소가 인체 면역글로불린을 분해하는지 관찰하고자 인체의 분비 IP. 혈청 IgA 및 IgG를 살아있는 원충. 원충의 용출액 및 분비-배설 액과 DTT를 넣어 반응시켰다. 여러 계열의 단백질분해효소 저해제(aminopeptidase, serine, metallo, cystelrle계열)를 살아있는 질편모충과 미리 반응시킨 후 세척하고 면역글로불린의 분해 단백질분해효소 활성 및 조직세포독성에 미치는 영향을 관찰하였다 살아있는 질편모충은 인체의 분비 IgA. 혈청 IgA 및 IgG를 분해하였는데 질편모충 수가 증가할수록 반응시간이 길수록 분해가 더 잘 이루어졌다 질푄모충의 용출액과 분비-배설액도 분비 IgA. 혈청 IgA 및 IgG를 분해하였다. Cysteine, serine계 열의 단백질분해효소 저해제 (I-64 antipain, iodoacetic acid, iodoacetamide, TLCK)를 처리한 질편닐충은 분비 IgA의 분해를 저해하였으며. 단백질분해효소저해제로 처리한 경우 질편모충의 단백질븐해효소 활성은 감소하였고 HeLa세포에 대한 독성이 감소하였다. 이상의 성적을 종합하면 질편모충에서 분비되는 단백질분해효소는 시험관내에서 조직세포에 세포독성을 나타내며 또한 인체면역글로불린을 분해하여 숙주의 방어기전에 대한 도피물질로 작용하는 것으로 생각된다.

Bioactive compounds extracted from leaves and twigs of Goniothalamus griffithii include pinocembrin (PCN) and goniothalamin (GTN). The objectives of this study were to investigate the cytotoxic activities of PCN and GTN and their influence on molecular signaling for cell death in several human cancer cell lines compared to normal murine fibroblast NIH3T3 cells. GTN exhibited the most potent cytotoxicity against MCF-7 > HeLa > HepG2 > NIH3T3 cells with $IC_{50}$ values of 7.33, 14.8, 37.1 and $65.4{\mu}M$, respectively, whereas PCN was cytotoxic only to HepG2 cells with $IC_{50}$ values of ${\sim}80{\mu}M$. Apoptotic cell death was confirmed by staining the cells with annexin V-FITC and propidium iodide (PI) employing flow cytometry. Apoptosis was shown by externalization of phosphatidylserine in goniothalamin-treated MCF-7 cells in a dose response manner. Positive PI-stained cells with the typical morphology of apoptotic cells were increased dose-dependently. Furthermore, reduction of mitochondrial transmembrane potential was found in goniothalamin-treated MCF-7, HepG2 and HeLa cells. GTN treatment in MCF-7 increased caspase-3, -8 and -9 activities while GTN-induced HeLa cells showed an increase of both caspase-3 and -9 activities. But an increased caspase-8 activity was demonstrated in GTN- and PCN-treated MCF-7 and HepG2 cells, respectively. Taken together, GTN- and PCN-induced human cancer cell apoptosis was through different molecular mechanisms or signaling pathways, which might be due to different machineries in different types of cancer cells, as evidenced by the compound-modulated caspase activities in both intrinsic and/or extrinsic pathways.
