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 ...
Discovery of Potent, Selective, and Orally Bioavailable Small-Molecule Modulators of the Mediator Complex-Associated Kinases CDK8 and CDK19.
(AMER CHEMICAL SOC, 2016-02-11)
The Mediator complex-associated cyclin-dependent kinase CDK8 has been implicated in human disease, particularly in colorectal cancer where it has been reported as a putative oncogene. Here we report the discovery of 109 ...
Inhibition of mTOR-kinase destabilizes MYCN and is a potential therapy for MYCN-dependent tumors.
(IMPACT JOURNALS LLC, 2016-09-06)
MYC oncoproteins deliver a potent oncogenic stimulus in several human cancers, making them major targets for drug development, but efforts to deliver clinically practical therapeutics have not yet been realized. In childhood ...
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 ...
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 ...
MIR21 Drives Resistance to Heat Shock Protein 90 Inhibition in Cholangiocarcinoma.
(W B SAUNDERS CO-ELSEVIER INC, 2018-03-01)
BACKGROUND & AIMS: Cholangiocarcinomas (CCA) are resistant to chemotherapy, so new therapeutic agents are needed. We performed a screen to identify small-molecule compounds that are active against CCAs. Levels of microRNA ...
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 ...
Patient-derived organoids model treatment response of metastatic gastrointestinal cancers.
(AMER ASSOC ADVANCEMENT SCIENCE, 2018-02-23)
Patient-derived organoids (PDOs) have recently emerged as robust preclinical models; however, their potential to predict clinical outcomes in patients has remained unclear. We report on a living biobank of PDOs from ...
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 ...
