The utilization of natural compounds as therapeutic agents to treat pancreatic cancer has recently focused on natural drug research. Calotropis gigantea has long been believed to be a medicinal plant that helps in treating various diseases. The bioactive compounds 9-metoxipinoresinol and isoliquiritigenin isolated from C. gigantea leaves are proven to act as therapeutic agents by inhibiting the cancer cell growth of Panc-1 cells. This study aimed to screen the potential molecular inhibition mechanisms of 9-metoxipinoresinol and isoliquiritigenin against pancreatic cancer development in-silico. We analyzed the activity of the aforementioned two compounds as inhibitors of several proteins that play a role in the growth of pancreatic cancer cells, such as GCNT3, GOT1, c-Met, PPARγ, BUB1, and NF-κβ, through molecular docking investigation. Our data suggested that 9-metoxipinoresinol and isoliquiritigenin were able to have well interaction with the target proteins, in which the predicted affinity energy ranged between -6.8 and 8.7 kcal/mol. The docking scores of 9-metoxipinoresinol and isoliquiritigenin were higher than the standard drug used (gemcitabine). Based on the binding affinity energy, GCNT3 and BUB1 are potentially to be used as target molecules for cancer therapy using 9-metoxipinoresinol and isoliquiritigenin, respectively.
Hazardous metal pollution has raised a global concern to its increasing trend in response to industrial growth. As an emerging economy, Indonesia starts to receive a backlash of increasing anthropogenic activities resulting in higher emission of heavy metal pollutants. Heavy metals are non-biodegradable pollutants and toxic to humans and other living organisms. Herein, we have reviewed published investigations on the contamination of heavy metals (Pb, Cu, Hg, Ni, Cd, Zn and As) in aquatic and terrestrial animals, attributed to anthropogenic activities in Indonesia. Some reports found the contamination levels have surpassed the tolerable limits of international standards. Most of the research was conducted in the industrial area, indicating that the heavy metal released into the environment can reach the human body through the food chain. A report in a non-industrial area suspected the contamination to be originated from the chain of anthropogenic activities (fertiliser industry—agriculture—livestock industry).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
