Subtilisin-like Serine Protease Targeted Library

As one of the most important representatives of serine proteases, subtilisin-like serine proteases are widely present in a diversity of organisms, but mainly in plants. Subtilases have a wide range of biological functions, from protein turnover and plant development to interactions with the environment, and they have been gaining increasing attention with regard to their involvement in plant defence responses against the most diverse pathogens. As a result, there has been an increasing number of studies on subtilases and serine protease inhibitors secreted by pathogens. These extracellular proteases secreted by fungi may act as virulence factors. Such secreted enzymes may play a central role in the establishment of pathogens. Although subtilisin-like serine proteases are expanded among pathogenic fungi, this group of proteases is also ubiquitous among eukaryotes and presents a new and interesting target for drug development.

BOC Sciences is focused on offering 1,000 drug-like screening compounds that are small-molecule analogs of known subtilisin-like serine proteinase inhibitors with experimentally determined activity.

Library Design

BOC Sciences has designed a receptor-based library of potential subtilisin-like serine protease inhibitors by employing docking approach and molecular fitting method.

1. A receptor-based virtual screening process is developed based on X-ray data for the complexes: 1WVM, 4LVN
2. The compounds in the HTS compound collection have been pre-filtered using BOC Sciences' internal filters and then docked at the active site
3. Finally, 1,000 potential subtilisin-like serine protease inhibitors can be selected with computational chemistry and virtual screening techniques are generated successfully
