“…Plants have the capability to overcome extreme environmental conditions by synthesizing a category of metabolites often referred to as secondary metabolites [5]. These herbal metabolites have been used to treat human disease since the 19 th century [6]. Diseases such as malaria and cancer are being treated with bioactive molecules derived from plants, which have the advantage of less toxicity, and herbal medicine can be safer for human consumption [7].…”

Background Worldwide, ovarian cancer has a high mortality rate due to the difficulty in diagnosing early-stage disease and resistance to chemotherapy agents. Costunolide is a plant-derived sesquiterpene lactone with anti-oxidant properties. This study aimed to investigate the effects of costunolide on cell growth, apoptosis, autophagy, the production of reactive oxygen species (ROS), cleaved caspase-3, and cleaved caspase-9 on the multidrug-resistant ovarian cancer cell line, OAW42-A. Material/Methods The MTT assay determined the proliferation rate of OAW42-A multidrug-resistant ovarian cancer cells and the apoptosis rate was determined using propidium iodide (PI) staining. Autophagy was detected by measuring the expression of LC3 II. Fluorescence flow cytometry was used to measure the levels of reactive oxygen species (ROS) and the mitochondrial membrane potential. Protein expression of LC3 II, beclin 1, cleaved caspase-3, and cleaved caspase-9 were measured by Western blot. Results Costunolide treatment inhibited the growth of OAW42-A cells with an IC 50 of 25 μM, resulted in apoptotic cell death, increased the expression of Bax, and decreased the expression of Bcl-2. Confocal electron microscopy showed that costunolide induced autophagy in the OAW42-A cells. Western blot showed that costunolide treatment of OAW42-A cells increased the expression of the LC3 II, beclin 1, cleaved caspase-3, and cleaved caspase-9. Costunolide treatment significantly increased the levels of ROS and reduced the OAW42-A cell mitochondrial membrane potential. Conclusions Costunolide inhibited growth, apoptosis, ROS generation, and was associated with loss of mitochondrial membrane potential of OAW42-A multidrug-resistant ovarian cancer cells.

“…Based on the structure of these chemical entities, they have been classified into different groups. Sesquiterpene is one such group of metabolites that is ubiquitously found across the plant kingdom and have been shown to exhibit promising bioactivities [5]. Sesquiterpenes from several plants have shown the capacity to inhibit the proliferation of cancers such as lung cancer, breast cancer, and gastric cancer [6].…”

Antiproliferative Effects of Matricine in Gemcitabine-Resistant Human Pancreatic Carcinoma Cells Are Mediated via Mitochondrial-Mediated Apoptosis, Inhibition of Cell Migration, Invasion Suppression, and Mammalian Target of Rapamycin (mTOR)-TOR/PI3K/AKT Signalling Pathway

Background Pancreatic cancer is a major cause of mortality worldwide. Inefficient drugs, their adverse effects, and the development of drug resistance make it difficult to curb the growing incidence of pancreatic cancer. Against this backdrop, the development new drug regimens with no or negligible adverse effects is imperative. We assessed the anticancer effects of a plant-derived sesquiterpene – matricine – against capan-2 pancreatic cancer cells. Material/Methods Cell viability was determined by MTT assay. AO/EB, DAPI, and annexin V/PI staining were used to detect apoptosis. Transwell assays were used for monitoring of cell migration and invasion. Immunoblotting was used to examine the expression of proteins. Results The results showed that matricine halted the proliferation of capan-2 cells, with minimal toxic effects on normal pancreatic cells. The anticancer effects were due to the induction of apoptotic cell death, which was allied with activation of caspases 3 and 9, upregulation of Bax, and downregulation of Bcl-2. Moreover, matricine suppressed the migration and invasive abilities of pancreatic cancer cells at IC50. We also assessed the effects of matricine on the mTOR/PI3K/AKT signalling pathway. We found that matricine efficiently blocked this pathway, suggesting the anticancer potential of matricine. Conclusions Matricine induced antiproliferative effects in capan-2 human pancreatic cancer cells through inducing apoptosis, caspase activation, inhibition of cell migration and invasion, and blocking the mTOR/PI3K/AKT signalling pathway.

“…Herbs are the main sources for drugs. Many herbs are used in traditional medicine and have been developed to become therapeutic drugs [34]. B. ovata, C. oblongifolius, and E. succirubrum are Thai herbs in the plant genetic conservation project under the Royal Initiative of Her Royal Highness Princess Maha Chakri Sirindhorn (RSPG).…”

The incidence of lung cancer has increased while the mortality rate has continued to remain high. Effective treatment of this disease is the key to survival. Therefore, this study is a necessity in continuing research into new effective treatments. In this study we determined the effects of three different Thai herbs on lung cancer. Bridelia ovata, Croton oblongifolius, and Erythrophleum succirubrum were extracted by ethyl acetate and 50% ethanol. The cytotoxicity was tested with A549 lung cancer cell line. We found four effective extracts that exhibited toxic effects on A549 cells. These extracts included ethyl acetate extracts of B. ovata (BEA), C. oblongifolius (CEA), and E. succirubrum (EEA), and an ethanolic extract of E. succirubrum (EE). Moreover, these effective extracts were tested in combination with chemotherapeutic drugs. An effective synergism of these treatments was found specifically through a combination of BEA with methotrexate, EE with methotrexate, and EE with etoposide. Apoptotic cell death was induced in A549 cells by these effective extracts via the mitochondria-mediated pathway. Additionally, we established primary lung cancer and normal epithelial cells from lung tissue of lung cancer patients. The cytotoxicity results showed that EE had significant potential to be used for lung cancer treatment. In conclusion, the four effective extracts possessed anticancer effects on lung cancer. The most effective extract was found to be E. succirubrum (EE).
