Exploiting Protein Conformational Change to Optimize Adenosine-Derived Inhibitors of HSP70.
(AMER CHEMICAL SOC, 2016-05-26)
HSP70 is a molecular chaperone and a key component of the heat-shock response. Because of its proposed importance in oncology, this protein has become a popular target for drug discovery, efforts which have as yet brought ...
Structural and functional characterisation of human RNA helicase DHX8 provides insights into the mechanism of RNA-stimulated ADP release.
(PORTLAND PRESS LTD, 2019-09-13)
DHX8 is a crucial DEAH-box RNA helicase involved in splicing and required for the release of mature mRNA from the spliceosome. Here, we report the biochemical characterisation of full-length human DHX8 and the catalytically ...
Privileged Structures and Polypharmacology within and between Protein Families.
(AMER CHEMICAL SOC, 2018-12-13)
Polypharmacology is often a key contributor to the efficacy of a drug, but is also a potential risk. We investigated two hits discovered via a cell-based phenotypic screen, the CDK9 inhibitor CCT250006 (1) and the pirin ...
Discovery of a Chemical Probe Bisamide (CCT251236): An Orally Bioavailable Efficacious Pirin Ligand from a Heat Shock Transcription Factor 1 (HSF1) Phenotypic Screen.
(AMER CHEMICAL SOC, 2017-01-12)
Phenotypic screens, which focus on measuring and quantifying discrete cellular changes rather than affinity for individual recombinant proteins, have recently attracted renewed interest as an efficient strategy for drug ...
Structure-based drug design: aiming for a perfect fit.
(PORTLAND PRESS LTD, 2017-11-08)
Knowledge of the three-dimensional structure of therapeutically relevant targets has informed drug discovery since the first protein structures were determined using X-ray crystallography in the 1950s and 1960s. In this ...
The discovery of potent ribosomal S6 kinase inhibitors by high-throughput screening and structure-guided drug design.
(IMPACT JOURNALS LLC, 2013-08-25)
The ribosomal P70 S6 kinases play a crucial role in PI3K/mTOR regulated signalling pathways and are therefore potential targets for the treatment of a variety of diseases including diabetes and cancer. In this study we ...
Dissecting mechanisms of resistance to targeted drug combination therapy in human colorectal cancer.
(NATURE PUBLISHING GROUP, 2019-06-20)
Genomic alterations in cancer cells result in vulnerabilities that clinicians can exploit using molecularly targeted drugs, guided by knowledge of the tumour genotype. However, the selective activity of these drugs exerts ...
A fragment-based approach applied to a highly flexible target: Insights and challenges towards the inhibition of HSP70 isoforms.
(NATURE PORTFOLIO, 2016-10-06)
The heat shock protein 70s (HSP70s) are molecular chaperones implicated in many cancers and of significant interest as targets for novel cancer therapies. Several HSP70 inhibitors have been reported, but because the majority ...
