  • Publication number: 20220226393
    Abstract: Use of parasites and extracellular vesicles obtained from the parasites for a cancer treatment is provided. The use of parasites and extracellular vesicles obtained from parasites is for using in a treatment of a cancer, and loading an active substance on exosomes by using a drug loading capacity of exosomes, and thus, by carrying a specific drug directly to target cancer cells without causing any side effect on healthy cells and to enhance a bioavailability of the specific drug, achieving a desired effect in a tumor specific target region. Particularly Leishmania infantum parasite is used as a source for the extracellular vesicles.

  • Publication number: 20210015854
    Abstract: The present invention relates to a chemotherapeutic agent comprising a combination of alexidine dihydrochloride and sodium pentaborate pentahydrate. The chemotherapeutic agent includes 2.9 mg alexidine dihydrochloride compound and 2.5 mg sodium pentaborate pentahydrate compound, and is obtained by adding 0.5 ml dimethylsulfoxide compound into the alexidine dihydrochloride compound. Upon injecting them to the media containing healthy cells and cancer cells, their effects on cell viability were observed. In accordance with the obtained results; it was observed that when alexidine dihydrochloride solution at concentrations not harming healthy cells is combined with sodium pentaborate pentahydrate, pancreatic cancer cell viability decreased 10% more compared to use of alexidine dihydrochloride alone, and it was realized that this combination can be used as a chemotherapeutic agent for treatment of pancreatic cancer.
