Veronique Baron from BPS Bioscience discusses the tools required to research and develop new oncology therapies, such as proteins, antibodies, cell lines, assay kits and viral tools. In another presentation, Dr Hengshuo Liu from ACROBiosystems will examine the areas where proteins and innovation are advancing biomedicine.

Biochemical assays and X-ray crystallographic studies validated the ternary covalent complex formation and overall PPI stabilization via dynamic covalent crosslinking. The PPI between the hub protein 14-3-3 and estrogen-related receptor γ (ERRγ) was used as a pharmacologically relevant case study.

We often screen using a biochemical assay, but we can conduct cell-based screening as well. For fragment screening, we can screen with biophysical methods, such as thermal shift assays or, you may have heard about Surface Plasmon Resonance (SPR) which is a very sensitive biophysical technique used for fragment screening.

Biochemical assays have the highest success rate. The top 20 Pharma are moving away from proteins in biochemical assays and overexpressed targets in simple cell lines toward more physiologically relevant assays using primary cells, cocultures, 3-D cell systems, or organoids. Biologics are booming. Think again.

One point that comes out of Pat’s post is that it’s difficult to establish structure-activity relationships for low affinity ligands with a conventional biochemical assay. This is one reason that biophysical detection of binding using methods such as surface plasmon resonance (SPR) are favored in fragment-based lead discovery.

In our project, we used biochemical assays to identify which proteins interact with Rnf43.” “We wanted to know how Rnf43 works, and also what – in turn – controls Rnf43 and helps it to regulate Wnt signalling.” A crucial partner of Rnf43 turned out to be the protein Daam1.

The company has narrowed down their decision to three options: Option #1: Company Z performs the project internally and screens their in-house collection of 250,000 small molecules using a traditional fluorescence-based biochemical assay. The fluorescence method is high-throughput and kits are commercially available.

Initially, I would recommend aqueous solubility, membrane permeability, in vitro metabolic stability, and biochemical assays. Focus benchmarking efforts on simple, robust, relevant, clearly defined endpoints. These endpoints are reproducible, relatively inexpensive, and can provide reasonably large datasets.
