Abstract

The present project aims at the discovery of proteasome inhibitors. The proteasome is the main non-lysosomal proteolytic complex, and is already a validated target for the treatment of multiple myeloma, with potential validation for other human diseases, such as in the treatment of Chagas disease, leishmaniasis and inflammatory diseases. Thus, finding substances capable of inhibiting the proteasome is a validated strategy for multiple myeloma and other neoplasms. In this context, seventeen extracts of fungal and marine origin, among hundreds of extracts tested, presented proteasome inhibitory activity. These extracts will be prioritized for HPLC-UV-MS and UPLC-QTOF analyzes and for bioguided isolation of new proteasome inhibitors. In this way, the objective is to isolate and identify proteasome inhibitors from these extracts from invertebrates and marine and endophytic microorganisms, with unprecedented structural characteristics.
