A Spanish-Swiss Liaison to fight COVID-19

 

Barcelona, Spain and Villigen Switzerland – 14th April, 2020

 

Today, Prof. Jana Selent from the Hospital del Mar Medical Research Institute (IMIM) in Barcelona, Spain, and InterAx Biotech in Villigen, Switzerland announce a COVID-19 collaboration, funded by the catalán life sciences and healthcare innovation institution Biocat. The goal of this collaboration is to identify antiviral drugs for the treatment of COVID-19 by combining virtual screening of a 3D-structural database and assessing the effectiveness of these compounds to block viral entry.

In December 2019, the highly contagious and pathogenic human CoVs (the SARS-CoV-2) appeared in Wuhan (China), which has led to a pandemic with high morbidity and mortality. Prof. Selent and her team have now joined forces with InterAx Biotech to screen for potential antiviral compounds in a virtual 3D-structrual database by using specific computational algorithms and to subsequently test their effectiveness in a SARS-CoV-2 pseudovirus entry blocking assay. The main goal of this project is to identify antiviral drugs for the treatment of COVID-19 by reprofiling existing drugs. Prof. Selent says: ”For this project, we focus on two strategies that interfere with the cell entry of SARS-CoV-2. One is to target the spike glycoprotein S of SARS-CoV-2 and the other one is to tackle the serine protease TMPRSS2. We are excited to team up with InterAx Biotech on testing these compounds in the wet-lab and anticipate that such a dual strategy increases the success rate of discovering effective therapeutic agents against COVID-19.”

The team of InterAx Biotech and Professor Jana Selent’s team hope to test the first antiviral compounds by May 2020.

InterAx Biotech supporting the COVID-19 initiative

SARS-CoV-2/ACE-2 pseudovirus entry blocking assay

 

The spike glypcoprotein S of SARS-CoV-2 uses the human Angiotensin Converting Enzyme 2 (ACE2) as an entry receptor and recognizes it with a similar affinity to the 2002–2003 SARS-CoV isolates, which suggests it can spread efficiently in humans, in agreement with the numerous SARS-CoV-2 human-to-human transmission events reported to date (Walls et al., 2020).

 

In collaboration with its academic partners at the PSI, InterAx Biotech is establishing a pseudovirus entry assay using murine leukemia virus based pseudotyped particles expressing the SARS-CoV-2 spike protein (and other relevant SARS-CoV-2 envelope proteins). The assay is described in detail in Walls et al. (2020) and Millet et al. (2016, 2019) and will enable a medium-throughput (96 well format) screen for blocking the interaction of the SARS-CoV-2 spike glycoprotein (and other envelope proteins) and the human ACE2 expressed in a host target cell line. This assay is suitable to be performed in the BSL-2 facilities at PSI and non-infective compounds ranging from small molecules to antibody sera can be tested. For detailed information please send an Email to contact@interaxbiotech.com with COVID-19 in the header.

InterAx Biotech and Vrije Universiteit Amsterdam enter a collaboration to unlock novel chemical space for chemokine therapeutics

 

Villigen – Switzerland, Amsterdam – The Netherlands, May 31 2018

InterAx Biotech and Vrije Universiteit Amsterdam announce that they will combine complementary technologies to design bioactive molecules – so called POLYPHARMACOLOGICALS – that simultaneously target multiple chemokine receptors.

In the collaboration, InterAx Biotech and the Vrije Universiteit Amsterdam (Prof Rob Leurs and Prof Iwan de Esch) will combine their expertise in systems biology, virtual screening and novel protein-based biosensor assays to design and synthesize new chemical modulators with well-defined polypharmacological effects that can serve as new therapeutics. This unique process will accelerate drug discovery for unmet needs in oncology.

Maria Waldhoer (CSO, InterAx Biotech) said: “We are excited to complement our capabilities on identifying and optimizing lead compounds with superior chemical and biological properties with the strength and know-how on virtual screening and medicinal chemistry of the Vrije Universiteit Amsterdam. The funding support from Eurostars significantly facilitates this collaboration, which was initiated and co-designed by Dr. Chris de Graaf, who recently joined Heptares Therapeutics as Head of Computational Chemistry.

Rob Leurs (Professor of Medicinal Chemistry of Vrije Universiteit Amsterdam) adds: “Combining our long-standing expertise in GPCR drug discovery with a new biosensor-based screening platform and systems biology approach is very appealing. Moreover, targeting more than one GPCR is a really interesting challenge, but with the increasing availability of structural information and the latest computational technologies this should be within reach”.
