    Enamine and Endogena Therapeutics – a Successful, Multi-Year Drug ...

    Kyiv, Ukraine, April 19, 2023 - Enamine Ltd., a provider of drug discovery services empowered with the world’s largest collections of building blocks, fragments, and screening compounds, gave an update of its long-standing research collaboration with Endogena Therapeutics AG, a clinicalstage biotech company focused on the development of endogenous regenerative medicines.

    Enamine provides Endogena with its integrated capability in medicinal chemistry to support Endogena’s small molecule drug discovery programs in the fields of hit finding, hit-to-lead and lead optimization.

    The companies have been collaborating under a Full Time Equivalent (FTE) model since 2019. The two discovery partners have been continuing their research collaboration to date, their research relationship not being impacted by the war in Ukraine. This collaboration extension, along with many others and new ones established by Enamine since February 24, 2022, already under the conflict, is a systematic positive trend experienced by the company, that demonstrates the support of its customers and the trust they have in receiving high-quality service backed up by the unparalleled number of diverse building blocks available at Enamine.

    Sven Weiler, Vice President of Medicinal Chemistry at Endogena, commented: “The interaction with colleagues from Enamine has been a smooth one from the start. In addition to the FTE model, it is great to have access to their huge compound collection and be able to flexibly use Enamine’s capacity to its full potential. We value the output and responsiveness of the Enamine team, helping us to achieve our demanding milestones. It is stunning to see how well Enamine has been able to keep pace after February 2022.”

    Michael Bossert, Head of Strategic Alliances at Enamine, added: “After 13 months of the war in the country, we are especially pleased to announce our collaboration with Endogena, a longlasting partner we have been serving during those several years with extensive medicinal chemistry and SAR efforts”.

Computational Chemistry

To effectively speed up your discovery process

Computational chemistry along with virtual screening plays an essential role in early Drug Discovery. Molecular modeling methods and screening technics become more and more sophisticated and together with machine learning are powerful tools for initial hit finding. The latest advances resulted in the drastic rise of Artificial Intelligence (AI) models, which now play a major role in every sector of pharmaceutical industry from early discovery to manufacturing and patient use.

Request

Application of CADD (computer-aided drug design) in early stages allows significant savings on cost and time needed for data analysis after a large HTS campaign. Deep learning of protein structure and application of the latest calculation algorithms can enrich your hit rate up to 10-15%.

Being the largest supplier of Screening compounds and Fragments we extensively use all available computational chemistry tools and develop our own algorithms and approaches in hit finding. Using our experience we designed over 70 Targeted and Diversity libraries. Our experts participate in collaborations with leading scientific groups in computational chemistry field, confirmed by number of papers.

We will be happy to help you with in silico screening of our 3M Screening Collection or selected part from our REAL Database, as well as provide all the following CADD services:

  • Virtual screening, Structure or Ligand-based. Docking calculation and 3D Pharmacophore search.
  • Compound Library design considering all sensitive aspects of your project.
  • Homology modeling of protein structures using AlpfaFold and search of potential binding sites.
  • Molecular Dynamics (MD) simulations, protein structure and ligand interaction optimization.
  • Activity analysis and QSAR modeling
  • Design of hit follow-up libraries. Hit expansion and hit exploration.

Request

Our proven high potential to accelerate and enhance drug discovery projects has been recognized by a recently drastically growing number of clients – from academic labs to big pharma companies viaSME’s. The number of chemical FTE’s outsourced to Enamine has doubled since 2019. Currently only 1/3 of our chemists are engaged in FTE collaborations and we can easily expand our service branch by relocating additional chemists from non-exclusive synthesis for our public catalogs.

FTE chemistry support

Skillful chemists

Enamine is a global leader in synthetic innovation in medicinal chemistry. We have over 650 skillful chemists with scientific expertise in various fields of chemistry widely documented in the peer-reviewed scientific journals. Our chemists have in-depth experience in a wide number of unique chemical techniques such as fluorination with SF4, photochemistry in flow, electrochemistry, high-pressure hydrogenation etc., which are well validated at Enamine and are scarcely available at other CRO’s.

Building Blocks

Our FTE rate includes free-of-charge access to most of our building blocks and the rest is offered with a sizeable discount. Our clients benefit from our enormous experience in building block synthesis. Enamine’s collection of make-on-demand “MADE” building blocks provides an important source of ideas and inspiration.
