VBY-825 is a novel, reversible cathepsin inhibitor with high potency against cathepsins B, L, S and V.IC50 value: Target: 130/250/250/330/2.3/4.7 nM(Ki for cathepsin S/L/ZV/Bhumanized-rabbit cathepsin K/cathepsin F) [1]VBY-825 is a potent inhibitor of the assayed cathepsins and its potency against at least one cathepsin, cathepsin S, extends across species relevant for pharmacology studies, specifically mouse. 10 mg/kg/day dose of VBY-825 achieves a trough plasma concentration >200nM, which is well above that required for full inhibition of the intracellular activity of cathepsins B, F, K, L, S and V in both mouse and human cell lines.

Discovery of SARS-CoV-2 antiviral drugs through large-scale compound repurposing
Nature 2020 Oct;586(7827):113-119.PMID:32707573DOI:10.1038/s41586-020-2577-1.
The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 2019 has triggered an ongoing global pandemic of the severe pneumonia-like disease coronavirus disease 2019 (COVID-19)1. The development of a vaccine is likely to take at least 12-18 months, and the typical timeline for approval of a new antiviral therapeutic agent can exceed 10 years. Thus, repurposing of known drugs could substantially accelerate the deployment of new therapies for COVID-19. Here we profiled a library of drugs encompassing approximately 12,000 clinical-stage or Food and Drug Administration (FDA)-approved small molecules to identify candidate therapeutic drugs for COVID-19. We report the identification of 100 molecules that inhibit viral replication of SARS-CoV-2, including 21 drugs that exhibit dose-response relationships. Of these, thirteen were found to harbour effective concentrations commensurate with probable achievable therapeutic doses in patients, including the PIKfyve kinase inhibitor apilimod2-4 and the cysteine protease inhibitors MDL-28170, Z LVG CHN2, VBY-825 and ONO 5334. Notably, MDL-28170, ONO 5334 and apilimod were found to antagonize viral replication in human pneumocyte-like cells derived from induced pluripotent stem cells, and apilimod also demonstrated antiviral efficacy in a primary human lung explant model. Since most of the molecules identified in this study have already advanced into the clinic, their known pharmacological and human safety profiles will enable accelerated preclinical and clinical evaluation of these drugs for the treatment of COVID-19.
A Large-scale Drug Repositioning Survey for SARS-CoV-2 Antivirals
bioRxiv 2020 Apr 17;2020.04.16.044016.PMID:32511357DOI:10.1101/2020.04.16.044016.
The emergence of novel SARS coronavirus 2 (SARS-CoV-2) in 2019 has triggered an ongoing global pandemic of severe pneumonia-like disease designated as coronavirus disease 2019 (COVID-19). To date, more than 2.1 million confirmed cases and 139,500 deaths have been reported worldwide, and there are currently no medical countermeasures available to prevent or treat the disease. As the development of a vaccine could require at least 12-18 months, and the typical timeline from hit finding to drug registration of an antiviral is >10 years, repositioning of known drugs can significantly accelerate the development and deployment of therapies for COVID-19. To identify therapeutics that can be repurposed as SARS-CoV-2 antivirals, we profiled a library of known drugs encompassing approximately 12,000 clinical-stage or FDA-approved small molecules. Here, we report the identification of 30 known drugs that inhibit viral replication. Of these, six were characterized for cellular dose-activity relationships, and showed effective concentrations likely to be commensurate with therapeutic doses in patients. These include the PIKfyve kinase inhibitor Apilimod, cysteine protease inhibitors MDL-28170, Z LVG CHN2, VBY-825, and ONO 5334, and the CCR1 antagonist MLN-3897. Since many of these molecules have advanced into the clinic, the known pharmacological and human safety profiles of these compounds will accelerate their preclinical and clinical evaluation for COVID-19 treatment.
Identification and pre-clinical testing of a reversible cathepsin protease inhibitor reveals anti-tumor efficacy in a pancreatic cancer model
Biochimie 2010 Nov;92(11):1618-24.PMID:20447439DOI:10.1016/j.biochi.2010.04.023.
Proteolytic activity is required for several key processes in cancer development and progression, including tumor growth, invasion and metastasis. Accordingly, high levels of protease expression and activity have been found to correlate with malignant progression and poor patient prognosis in a wide variety of human cancers. Members of the papain family of cysteine cathepsins are among the protease classes that have been functionally implicated in cancer. Therefore, the discovery of effective cathepsin inhibitors has considerable potential for anti-cancer therapy. In this study we describe the identification of a novel, reversible cathepsin inhibitor, VBY-825, which has high potency against cathepsins B, L, S and V. VBY-825 was tested in a pre-clinical model of pancreatic islet cancer and found to significantly decrease tumor burden and tumor number. Thus, the identification of VBY-825 as a new and effective anti-tumor drug encourages the therapeutic application of cathepsin inhibitors in cancer.
