Inverse Virtual Screening
One of the main challenges in pharmaceutical research is to identify the target(s) of a specific molecule with the purpose of elucidating the mechanism of action or understand side effects that may not be connected to the primary action of the compound. This is particularly important when studying natural products that, sometimes, are available in an amount not sufficient for extended biological tests. To facilitate this procedure, our group developed an innovative approach called Inverse Virtual Screening (more info here and here) that, using an automatic protocol, predicts the binding affinity of a single compound against a panel of selected targets.
2D Target Identification
Our group developed an innovative integrated approach for the identification of specific interactome and main macromolecular targets of a small pool of molecule (either natural or synthetic) to disclose their potential biological effect. The results obtained by Inverse Virtual Screening and chemical proteomics (i.e., DARTS) will be processed using a mathematical model to establish a quantitative affinity parameter, weighted on both methods, to detect the most promising interaction targets in the proteome of a specific cell (e.g., solid tumors) and/or organism (e.g., human, bacteria).
