Interfering with Host Proteases in SARS-CoV-2 Entry as a Promising Therapeutic Strategy
2020
Abstract: Due to its fast international spread and substantial mortality, the coronavirus disease COVID-19 evolved to a global threat. Since there is currently no causative drug against this viral infection available, science is striving for new drugs and other approaches to treat the new disease. Studies have shown that the cell entry of coronaviruses into host cells takes place through the binding of the viral spike (S) protein to cell receptors. Priming of the S protein occurs via hydrolysis by different host proteases. The inhibition of these proteases could impair the processing of the S protein, thereby affecting the interaction with the host-cell receptors and preventing virus cell …
From In Silico to Experimental Validation: Tailoring Peptide Substrates for a Serine Protease.
2020
Smart nanocarriers for the transport of drugs to tumor cells are nowadays of great interest for treating cancer. The use of enzymatic stimuli to cleave peptide-based drug nanocapsules for the selective release of nanocapsule cargo in close proximity to tumor cells opens new possibilities in cancer research. In the present work, we demonstrate a methodology for finding and optimizing cleavable substrate sequences by the type II transmembrane serine protease hepsin, which is highly overexpressed in prostate cancer. The design and screening of combinatorial libraries in silico against the binding cavity of hepsin allow the identification of a panel of promising substrates with high-calculated …
