ZoBio Introduces DNA-Encoded Library Service for Exploratory Drug Discovery Programs

Published

on

Officials at Leiden, Netherlands-based CRO ZoBio say the company has launched a DNA-Encoded Library (DEL) discovery service, which is designed to help biotech and pharmaceutical companies generate validated, progressible hits against novel and challenging drug targets.

The new offering combines structure-grade protein production, quantitative biophysics, DEL screening, off-DNA hit validation and X-ray crystallography into a single workflow, according to a company spokesperson, who explains that it enables clients to move beyond hit identification toward high-confidence starting points for drug discovery programs.

ZoBio maintains that unlike transactional DEL screening approaches that focus solely on hit generation, its platform is designed to deliver biologically relevant, structurally characterized hit matter with clear potential for progression. The service is particularly suited to exploratory and difficult-to-drug targets, including protein–protein interactions (PPIs) and targets with poorly defined binding pockets, where conventional screening approaches often fail, notes Gregg Siegal, CEO of ZoBio.

“Drug discovery teams today are increasingly focused on highly validated but technically challenging targets, where traditional screening approaches can struggle to deliver meaningful starting points,” he continues. “Our approach combines DEL technology with the structural biology, biophysics, and assay expertise needed to generate hits that clients can confidently progress.”

Siegal also points out that the DEL service is library-agnostic, enabling clients to access commercially available DEL collections or apply ZoBio’s workflow to proprietary client-owned libraries. The integrated platform reportedly includes:

  • Structure-grade protein production and characterization
  • Quantitative biophysical assay development using techniques such as SPR
  • Biophysically informed DEL selection design
  • Interactive DEL data analysis and hit prioritization
  • Off-DNA hit resynthesis and orthogonal validation
  • Structural characterization through X-ray crystallography
  • Mechanistic insight to support downstream optimization

The workflow is designed to support collaborative decision-making throughout the discovery process, helping clients rapidly establish whether difficult or exploratory targets are viable for further development, according to Siegal, who says that members of the ZoBio team will be available for meetings during the BIO International Convention in San Diego to discuss the new service.

New webinar: Tackling drug discovery challenges in cancer research

Published

on

Cancer cells

Hosted by Drug Discovery World and supported by Sartorius and BioIVT, this webinar will explore the opportunities and challenges that exist within cancer research drug discovery and development.

You will hear from Dr Sudha Rao, Chief Scientific Officer of Kazia Therapeutics, Karol Budzik, PhD, Business Development Associate at Vyriad Therapeutics and Lars van der Veen, Chief Scientific Officer at iOnctura.

Presentations will cover how cancer treatments have shifted towards reprogramming the biology driving tumour growth, immune escape and treatment resistance, the trajectory that in vivo CAR-T treatments are taking, and how challenging tumours burdened by stroma and immune-mediated resistance can be tackled.

Q&A with the speakers follows the presentations.

New Spectrometry Technique Could Aid Formulation Development

New Spectrometry Technique Could Aid Formulation Development

Published

on

A new technique combining two forms of spectrometry could help biopharmaceutical companies improve their choice of formulation buffer for antibody manufacturing by revealing how molecular forms and three-dimensional shapes of complex biologics respond to their environment. That’s the view of Christian Bleiholder, PhD, a professor at Florida State University who helped develop the technique.

According to Bleiholder, what happens structurally when a complex biological molecule, such as an antibody or viral spike protein, binds to its target is currently poorly understood.

“This is where [this approach] can help with the bioprocessing and formulation,” he says, as structural changes “can affect the lifespan [of the product] and lead to issues, such as aggregation.”

Because antibodies are complex, existing techniques tend to be powerful at different levels of complexity, he explains. Mass spectrometry is particularly powerful for distinguishing molecular composition, while structural approaches such as X-ray crystallography and cryo-electron microscopy can provide high-resolution structural information.

The challenge is understanding the link between these things within a heterogeneous sample, he says.

To overcome this, Bleiholder and his team worked with Bruker Daltonics to develop Tandem-Trapped Ion Mobility Spectrometry (Tandem-TIMS). This combines tandem ion mobility spectrometry with tandem mass spectrometry to disentangle three overlapping layers of molecular complexity: molecular form, three-dimensional shape, and binding or assembly state, he says.

He explains that, if the proteins have different structures, they can be characterized with tandem ion mobility spectrometry, and then mass spectrometry can be used to look at their molecular forms and binding states.

Going forward, Bleiholder hopes the technique can be used for formulation development but also earlier, during drug discovery of new products, such as multi-specific antibodies, to determine which molecular states are important and how those change when a biologic engages its target. He also plans to look at automating the technique.

Bleiholder spoke about using Tandem-TIMS at the Bioprocessing Summit in Boston earlier this year.
