In silico prediction and in vitro assessment of novel heterocyclics with antimalarial activity.

The development of new antimalarials is paramount to keep the goals on reduction of malaria cases in endemic regions. The search for quality hits has been challenging as many inhibitory molecules may not progress to the next development stage. The aim of this work was to screen an in-house library of heterocyclic compounds (HCUV) for antimalarial activity combining computational predictions and phenotypic techniques to find quality hits.

Pathogenesis and in vivo interactions of human Streptococcus agalactiae isolates in the Galleria mellonella invertebrate model.

Group B Streptococcus (GBS) is a gram positive bacterium colonizing the gastrointestinal and urogenital tracts in humans. However under certain conditions GBS invades leading to severe infections in neonates, pregnant women, immunocompromised patients and the elderly people. The precise mechanisms involved in the transition from colonizer to pathogen remain to be elucidated, however it has been suggested that environmental determinants may regulate gene expression resulting in GBS invasion.
