In order to understand more about the mode-of-action(s) of these drugs the metabolome of HPV16 E6 expressing cervical carcinoma cell lines was investigated using mass spectrometry (MS)-based metabolic profiling.

Abstract: Numerous studies have led to a better understanding of the mechanisms of action of viruses in systemic infections for the development of prevention strategies and very promising antiviral therapies. Viruses still remain one of the main causes of human diseases, mainly because the development of new vaccines is usually challenging and drug resistance has become an increasing concern in recent decades. Therefore, the development of potential antiviral agents remains crucial Citation: Mammari, N.; Krier, Y.; and is an unmet clinical need. One abundant source of potential therapeutic molecules are plants: Albert, Q.; Devocelle, M.; Varbanov, M.; on behalf of the OEMONOM.
