Glioblastoma multiforme (GBM) is an aggressive form of primary brain neoplasm that has a poor prognosis and is resistant to conventional treatment. There is a great need to develop new strategies to improve the outcome of this disease. PBI-05204, a supercritical CO2 Nerium oleander extract containing cardiac glycosides, such as oleandrin, has been tested in Phase I and II clinical trials for treatment of solid tumors.
This article encourages future studies to verify the applicability of oleandrin in antineoplastic therapeutic protocols, human and veterinary medicine, the investigation of antimetastatic properties, as well as the potential increase in patient survival and the decrease of tumor markers.
Bovine viral diarrhea virus (BVDV), bovine respiratory syncytial virus (BRSV), and bovine coronavirus (BCV) threaten the productivity of cattle worldwide. Development of therapeutics that can control the spread of these viruses is an unmet need. The present research was designed to explore the in vitro antiviral activity of the Nerium oleander derived cardiac glycoside oleandrin and a defined N. oleander plant extract (PBI-05204) containing oleandrin.
