Hit Discovery
The goal of hit discovery is to identify suitable chemical starting points to modulate a drug target. A hit can be, a.o., a small molecule, a protein or mRNA. Hit identification is performed via rational design, genome mining, (targeted) library screening, or in silico approaches.

Luis Salome Abarca about plant chemicals and the Hortus botanicus
What chemicals do plants have available, and what happens if they use them when faced with bacteria or fungi? That is what PhD candidate Luis Salomé Abarca is keen to learn. He studies plants’ survival and their use of chemical components in communication and defence. Salomé Abarca works at the Natural…
