Small-molecule targeting of brachyury transcription factor addiction in chordoma.
(2019-02)
Chordoma is a primary bone cancer with no approved therapy 1 . The identification of therapeutic targets in this disease has been challenging due to the infrequent occurrence of clinically actionable somatic mutations in ...
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 ...
Structure-Based Optimization of Potent, Selective, and Orally Bioavailable CDK8 Inhibitors Discovered by High-Throughput Screening.
(AMER CHEMICAL SOC, 2016-10-27)
The mediator complex-associated cyclin dependent kinase CDK8 regulates β-catenin-dependent transcription following activation of WNT signaling. Multiple lines of evidence suggest CDK8 may act as an oncogene in the development ...
Discovery of potent, orally bioavailable, small-molecule inhibitors of WNT signaling from a cell-based pathway screen.
(AMER CHEMICAL SOC, 2015-02-26)
WNT signaling is frequently deregulated in malignancy, particularly in colon cancer, and plays a key role in the generation and maintenance of cancer stem cells. We report the discovery and optimization of a 3,4,5-trisubstituted ...
Assessing the mechanism and therapeutic potential of modulators of the human Mediator complex-associated protein kinases.
(ELIFE SCIENCES PUBLICATIONS LTD, 2016-12-09)
Mediator-associated kinases CDK8/19 are context-dependent drivers or suppressors of tumorigenesis. Their inhibition is predicted to have pleiotropic effects, but it is unclear whether this will impact on the clinical utility ...
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 ...
A selective chemical probe for exploring the role of CDK8 and CDK19 in human disease.
(NATURE PUBLISHING GROUP, 2015-12-01)
There is unmet need for chemical tools to explore the role of the Mediator complex in human pathologies ranging from cancer to cardiovascular disease. Here we determine that CCT251545, a small-molecule inhibitor of the WNT ...
Demonstrating In-Cell Target Engagement Using a Pirin Protein Degradation Probe (CCT367766).
(AMER CHEMICAL SOC, 2018-02-08)
Demonstrating intracellular protein target engagement is an essential step in the development and progression of new chemical probes and potential small molecule therapeutics. However, this can be particularly challenging ...
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 ...
