Anti-Proliferative Activity and Apoptosis Induction of an Ethanolic Extract of Boesenbergia pandurata (Roxb.) Schlecht. against HeLa and Vero Cell Lines

<em>In vitro</em> study of pinostrobin propionate and pinostrobin butyrate: Cytotoxic activity against breast cancer cell T47D and its selectivity index

Backgrounds: Pinostrobin has the potential activity as an anti-cancer. However, its activity is still lower than the anticancer drugs on the market. To increase its activity, pinostrobin derivatives have been synthesized, namely pinostrobin propionate and pinostrobin butyrate, which are predicted to have better activity and lower toxicity than pinostrobin after being tested by in silico approach. So the compound deserves to be tested for its anticancer activity and selectivity on normal cells. Objective: This study aims to determine the anticancer activity of pinostrobin propionate and pinostrobin butyrate against the T47D breast cancer cell line and its selectivity against the Vero cell line. Methods: The cytotoxicity test which is anticancer activity test and its selectivity on normal cell were carried out using the MTT(3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assay. The cells used were breast cancer cell line T47D and normal Vero cells. The test results were analyzed using a microplate reader with a wavelength of 570 nm. Results: From the analysis of anticancer activity on T47D cells, the IC50 values of pinostrobin, pinostrobin propionate, and pinostrobin butyrate were 2.93, 0.57, and 0.40 mM, respectively. While the results of the cytotoxicity test on Vero cells obtained the CC50 value of pinostrobin, pinostrobin propionate, pinostrobin butyrate was 1.27, 0.94, and 0.89 mM, respectively. So the SI value of pinostrobin (SI=0.4) is smaller than its derivatives (SI=1.7 and 2.2). Meanwhile, pinostrobin butyrate is more selective than pinostrobin propionate. Conclusions: It can be concluded that pinostrobin propionate and pinostrobin butyrate compounds have greater activity and selectivity than pinostrobin so these compounds are promising to be further developed as anticancer candidates.

A Potential Anticancer Mechanism of Finger Root (Boesenbergia rotunda) Extracts against a Breast Cancer Cell Line

Breast cancer is the most common type of cancer women suffer from worldwide in 2020 and the 4th leading cause of cancer death. Boesenbergia rotunda is an herb with high potential as an anticancer agent. This study explores the potential bioactive compounds in B. rotunda as anti-breast cancer agents using in silico and in vitro approaches. The in silico study was used for active compound analysis, selection of anticancer compound candidates, prediction of target protein, functional annotation, molecular docking, and molecular dynamics simulation, respectively. The in vitro study was conducted by measurement toxicity, rhodamine 123, and apoptosis assays on T47D cells. Based on the KNApSAcK database, B. rotunda contained 20 metabolites, which are dominated by chalcone and flavonoid groups. Seven of them were predicted to have anticancer activity, namely, sakuranetin, cardamonin, alpinetin, 2S-pinocembrin, 7.4'-dihydroxy-5-methoxyflavanone, 5.6-dehydrokawain, and pinostrobin chalcone. These compounds targeted proteins related to cancer progression pathways such as the PI3K/Akt, FOXO, JAK/STAT, and estrogen signaling pathways. Therefore, these compounds are predicted to inhibit growth and induce apoptosis of cancer cells through their interactions with MMP12, MMP13, CDK4, JAK3, VEGFR1, VEGFR2, and KCNA3. Anticancer activity of B. rotunda through in vitro study confirmed that B. rotunda extract is strong cytotoxic and induces apoptosis of breast cancer cell lines. This study concludes that Boesenbergia rotunda has potency as an anticancer candidate.

Review On Documented Medicinal Plants Used For The Treatment Of Cancer

Background:

Cancer is a frightful disease and it is the second leading cause of death worldwide. Naturally derived compounds are gaining interest of research workers as they have less toxic side effects as compared to currently used treatments such as chemotherapy. Plants are the pool of chemical compounds which provides a promising future for research on cancer.

Objective:

This review paper provides updated information gathered on medicinal plants and isolated phytoconstituents used as anticancer agents and summarises the plant extracts and their isolated chemical constituents exhibiting anticancer potential on clinical trials.

Methods:

An extensive bibliographic investigation was carried out by analysing worldwide established scientific databases like SCOPUS, PUBMED, SCIELO, ScienceDirect, Springerlink, Web of Science, Wiley, SciFinder and Google Scholar etc. In next few decades, herbal medicine may become a new epoch of medical system.

Results:

Many researches are going on medicinal plants for the treatment of cancer but it is a time to increase further experimental studies on plant extracts and their chemical constituents to find out their mechanism of action at molecular level.

Conclusion:

The article may help many researchers to start off further experimentation that might lead to the drugs for the cancer treatment.

Antitumor effects of baicalin on ovarian cancer cells through induction of cell apoptosis and inhibition of cell migration in vitro

Baicalin, an active flavone isolated from Scutellaria baicalensis Georgi, has been demonstrated to induce various beneficial biochemical effects such as anti‑inflammatory, anti‑viral, and antitumor effects. However, the antitumor mechanism of baicalin is not well understood. In the present study, baicalin was demonstrated to inhibit the viability and migration of a widely used ovarian cancer cell line, A2780, in a dose‑dependent manner. MTT assays revealed that cell viability significantly decreased in ovarian cancer cells treated with baicalin compared with untreated cells, without effect on normal ovarian cells. Flow cytometric analysis indicated that baicalin suppressed cell proliferation by inducing apoptosis. The underlying mechanisms involved were indicated to be downregulation of the anti‑apoptotic protein B‑cell lymphoma 2 apoptosis regulator and activation of caspase‑3 and ‑9. In addition, wound healing and transwell assays revealed that cell migratory potential and expression of matrix metallopeptidase (MMP)‑2 and MMP‑9 were significantly inhibited when cells were exposed to baicalin, compared with untreated cells. The present study therefore suggested that baicalin has the potential to be used in novel anti‑cancer therapeutic formulations for treatment of ovarian cancer.
