Cancer is one of the diseases that is the highest cause of death in humans. Most human cancer cells are formed as a result of over-expression of anti-apoptotic proteins. Thus, the activation of these proteins can inhibit pro-apoptotic proteins, then apoptosis will be inhibited so that other apoptotic pathways need to be activated to prevent cancer cells from developing. Current cancer treatments, such as chemotherapy using synthetic compounds, have various side effects, so research on natural based therapies can be used as an alternative in cancer treatment. Curcuma sumatrana is one of the plants of the Zingiberaceae family which is an endemic plant from Sumatra which is found along the Bukit Barisan. The research was carried out in silico by analyzing the potential bioactivity of the compounds, testing the bioavailability, toxicity, and molecular docking of the bioactive compounds from the ethanol extract of the rhizome of C. sumatrana which had been previously identified through gas chromatography-mass spectroscopy (GCMS) analysis. The results obtained that the compound 9-Acetyl-S-octahydrophenanthrene and 3-Oxoandrosta-1,4-dien-17.beta.-spiro-2'-3'-oxo-oxetanecontained in C. sumatrana has the potential to be developed as an anticancer where the compound has good bioavailability value and is not toxic and potentially can trigger apoptosis. However, the results of this study need to be analyzed further with an in vitro or in vivo approach. [ABSTRACT FROM AUTHOR]

Conventional chemotherapy substances are associated with mild to severe side effects that affect both healthy and cancer cells. It is presumed to improve therapeutic efficacy in coexistence reducing chemotherapy's side effects. Fucoidan is an anticancer bioactive compound derived from Sargassum sp. that has low cytotoxic activity. The purpose of this study was to explore the effectiveness of anticancer activities of fucoidan from Sargassum sp. against breast cancer then analyze the suitability of nano transdermal patch of fucoidan and blueprint the long-term research design of nano transdermal patch as a chemoprevention agent in the chemotherapeutic management of breast cancer. This research was performed through a literature study and in silico study by imposing carbonic anhydrase IX (CA IX) as a marker of hypoxia and metastatic state of cancer cells. The results showed that the fucoidan from Sargassum sp. effectively induced apoptosis and prevented metastasis of breast cancer cells through the Bcl-2, Bcl-w, and bad pathways. Fucoidan, in addition, was predicted to inhibit CA IX by Glu4 Glu5, Leu7, Pro8, and Asp6 residues. Therefore, the delivery of fucoidan is favored to have a local effect on the site of breast cancer cells by nano transdermal patch preparations using fucoidan nanoparticle polymer. Further nano transdermal patch development as a treatment for breast cancer is suggested through the stages of formulation optimization, optimum formula activity testing, patent filing, and distribution in health services.
