Using fungal tyrosinase-based in vitro biochemical assay, we obtained one compound ( 3k ) which could inhibit tyrosinase activity, and the other compound ( 4f ) that stimulated tyrosinase activity. In the present study, we investigated these compounds for their potential as antagonists or agonists of tyrosinase.

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.

In the Compatibility Issues section the authors state: Looking beyond laboratory-to-laboratory variability of assays that are nominally the same, there are numerous reasons why literature results for different assays measured against the same “target” may not be comparable.

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.

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.

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.

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.
