My main criticism of BW2014 that is that the rhetoric is not supported by data and I’ve always seen the article as something of a propaganda piece. Interference with read-out and undesirable MoAs are very different problems in drug discovery and the failure to recognize this point is a serious deficiency that is shared by BW2014 and BH2010.
The researchers also looked at the tool’s ability to detect changes in cellular phenotypes after exposure to drugs and small molecule compounds. Typically, studying drug therapies is an expensive and time-consuming undertaking.
Another good example is really any process optimization / screening domain, whether it’s cloning screening, media formulation, drug screens, etc. At Beckman Coulter Life Sciences , he supports the applications development team in NGS, cell-basedassays, and proteomics workflows.
I’ll start the review of L2021 with annotation of the abstract: "Physicochemical descriptors commonly used to define ‘drug-likeness’ and ligand efficiency measures are assessed for their ability to differentiate marketed drugs from compounds reported to bind to their efficacious target or targets. [I
I’ll be taking a look at H2023 (Expanding Chemical Probe Space: Quality Criteria for Covalent and Degrader Probes) in this post and this article has also been discussed In The Pipeline. This Perspective is intended to jumpstart this important scientific discussion. Subscripting doesn't work well in blogger and so I'll use K.i
Different assay organism or cell types: the target protein may be recombinantly expressed in different cell types (the target ID in ChEMBL is assigned based on the original source of the target), or the assays may be run using different cell types.
Encountering words like “truth” and “beauty” (here's a good example ) in the titles of scientific articles always sets off warning bells for me and I’ll kick off blogging for 2024 with a look at FM2024 (Structure is beauty, but not always truth) that was recently published in Cell.
Janette Thomas leads a small biotech company (Five Alarm Bio) 1 on a mission to develop drugs targeting the chronic diseases associated with ageing. The company generates valuable information from imaging analyses and various biological assays, such as the scratch assay, which examines cell migration.
For example, in describing how potency should be demonstrated for CGT products, the 2011 guidance simply stated that potency for gene therapy products is derived from “at least two biological activities for its potency: the ability to transfer a genetic sequence to a cell; and the biological effect of the expressed genetic sequence.”
The authors of S2023 claim to have revealed “suboptimal use of chemical probes in cell-based biomedical research” and I’ll start by taking a look at the abstract (my annotations are italicised in red): Chemical probes have reached a prominent role in biomedical research, but their impact is governed by experimental design.
