Next generation antiviral screening
NeoVirTech has developed a breakthrough technology to directly visualize and quantify in real time virus infection and replication in living cells. NeoVirTech possesses the exclusive worldwide license for the ANCHORTM technology, a new generation of autofluorescent system allowing the visualization of DNA in living cells.
The ANCHOR system is composed of two parts:
- The ANCH sequence: short (from 200NT to 1kb) and unique (non repetitive), it contains sequence that contains nucleation seeds for the binding of OR proteins. Insertion of the sequence does not perturb chromatin assembly or create fragile sites in the target DNA.
- The OR-fluorescent protein expressing gene which specifically recognizes and spreads on the ANCH sequence, triggering the formation of a fluorescent focus easily detectable and quantifiable by microscopy (either classical or High content).
The ANCH sequence is cloned upstream of the Or-FP expressing gene, therefore, this ANCHOR cassette will convert the target DNA into an autofluorescent molecule (plasmid, gene, transposon, virus). For small viruses, ANCH and OR sequences are used separately.
NeoVirTech uses four different ANCHOR systems with different length and fused to their corresponding fluorescent proteins that can be used in combinations to detect several class of DNA simultaneously. Using the ANCHORTM technology, fitness studies visualizing co-infection of several viruses in real time are now possible.
High content Screening
Our models are conceived specifically for high content screening campaign. We offer several screening models for antiviral discovery in human and animal health and propose screening services using customer models (viral or not) and our internal compound libraries.
- Library collection and formatting
- Screening of antiviral activities on one or several viral models and on one or several cell lines (Viral inactivation, attachment, penetration, replication, cell to cell spread).
- IC50/90 calculation
- Toxicity testing
- Hit sorting
- Hit optimization
NeoVirTech develops custom autofluorescent viruses or viral vectors for a specific application such as antiviral discovery, gene transfer studies, viral based vaccine development, oncolytic vectors and other broad applications, depending on customer’s interest.
- Viral vector collection and amplification
- ANCHORTM tagged version of the virus of interest and validation
- Production of the autofluorescent vector
- Determination of antiviral activities on this specific construct
NeoVirTech offers the ANCHORTM technology for internal use by licensing.
- Access to the ANCHORTM technology and generation of specific construct if needed
- Transfer of the ANCHORTM technology to the customer's R&D laboratory
- Technical support and troubleshooting
What our clients say
Neovirtech’s technology platform uniquely allows rapid and accurate screening of compounds against a range of clinically relevant viral pathogens. Dr. Franck Gallardo and his team provide an in-depth knowledge base and an interactive environment for study design, planning and execution. I would highly recommend Neovirtech for antiviral drug screening

Advances in immune suppression allows the grafting of life saving cells and organs between patients. Immune suppression unfortunately also promotes viral infections normally controlled by the immune system making the development of novel antivirals that work under immune suppression an imperative task. The underlying mechanisms causing reactivation or promoting viral replication are often related to dynamic changes in the chromatin status of the viral genome. Working with NeoVirtech gives us the unique opportunity to label viral genomes with the ANCHOR technology and study the dynamic behaviour of individual viral genomes in living cells under different environmental conditions. Understanding how viral genomes respond in living cells is key to understanding and developing novel drug concepts and mechanistic understanding of existing antivirals. Setting up the technology with NeoVirtech was simple, professional and driven by scientific understanding … the start of a great ongoing relationship!

Viral diseases cause significant financial loss in animal production systems. Despite the importance of viral pathogens as primary and secondary etiologic agents in cattle, pigs and poultry, no antiviral products are commercially licensed for use in veterinary medicine. Collaboration with NeoVirTech give us unique opportunity to explore the potential of antiviral therapy in the veterinary virology domain. Among viral animal diseases, we are particularly interested in poxviruses induced diseases of rabbit and poultry (myxomatosis, fowlpox), and labelling of DNA viral genomes with the ANCHOR technology will allow us to rapidly screen available compounds for antiviral significative effects.

Expertise and outstanding skills that rely on R&D of high scientific level.
This company, a true example of dynamism and inventiveness, is a pride for our institute.
Dr. Bernard DucommunHead of ITAV lab
Based on 25 years of research in the macrocyclic chemistry field, we had accumulated several hundreds of compounds in the lab that were developed for human health. We were interested in testing the activity of these compounds in the anti-infectious domain. NeoVirTech was immediately responsive for this project, and with high professionalism, completely met our needs. Their expertise in screening and the speed and quality of the generated data led us to rapidly identify 3 hit compounds in our library as new inhibitors of hCMV. These results have been recently published and highlighted by the cover of ACS infectious disease in august 2015. Without the expert assistance of NeoVirTech, it would have been impossible to rapidly test and value our library, opening new perspectives for our research activities. Thank you NeoVirTech for this beautiful and precious collaboration.
