Naphthoquinones eleutherin and isoeleutherin have demonstrated promising antibacterial activity, probably due to their quinone structure, which can generate reactive oxygen species. The study examines the activities of pathogens, such as and , associated with antimicrobial resistance and explores their potential mechanisms of action. The MIC, IC, and MBC were determined.

Article Synopsis
  • Ololygon skuki is a newly studied species found only in a specific area of the Atlantic Forest in Alagoas, Brazil, with limited prior research on its adults and larvae.
  • Current research reveals that O. skuki is closely related to other species in the O. argyreornata group and includes new findings such as its unique nuptial pad and vocalization characteristics.
  • The geographic range of O. skuki has been expanded significantly, with a new discovery placing it about 425 km southwest of its original location, and its call consists of distinctive pulsed notes with a certain frequency range.

The search for bioactive compounds for the treatment of several diseases has led to the study of endophytic fungi. Neoplastic diseases are among the most significant health concerns due to their high mortality rate, and there is a dearth of efficacious pharmaceutical agents for the treatment of cancer. Gastric cancer is one of the most aggressive forms of cancer and is among those with the highest mortality rates in Brazil.
