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, 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 ...
Binding to an Unusual Inactive Kinase Conformation by Highly Selective Inhibitors of Inositol-Requiring Enzyme 1α Kinase-Endoribonuclease.
(AMER CHEMICAL SOC, 2019-02-19)
A series of imidazo[1,2- b]pyridazin-8-amine kinase inhibitors were discovered to allosterically inhibit the endoribonuclease function of the dual kinase-endoribonuclease inositol-requiring enzyme 1α (IRE1α), a key component ...
Near-infrared dual bioluminescence imaging in mouse models of cancer using infraluciferin.
(eLIFE SCIENCES PUBL LTD, 2019-10-15)
Bioluminescence imaging (BLI) is ubiquitous in scientific research for the sensitive tracking of biological processes in small animal models. However, due to the attenuation of visible light by tissue, and the limited set ...
C8-substituted pyrido[3,4-d]pyrimidin-4(3H)-ones: Studies towards the identification of potent, cell penetrant Jumonji C domain containing histone lysine demethylase 4 subfamily (KDM4) inhibitors, compound profiling in cell-based target engagement assays.
(ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2019-09-01)
Residues in the histone substrate binding sites that differ between the KDM4 and KDM5 subfamilies were identified. Subsequently, a C8-substituted pyrido[3,4-d]pyrimidin-4(3H)-one series was designed to rationally exploit ...
Small molecule inhibitors of RAS-effector protein interactions derived using an intracellular antibody fragment.
(NATURE PORTFOLIO, 2018-08-09)
Targeting specific protein-protein interactions (PPIs) is an attractive concept for drug development, but hard to implement since intracellular antibodies do not penetrate cells and most small-molecule drugs are considered ...
Structure-based development of new RAS-effector inhibitors from a combination of active and inactive RAS-binding compounds.
(NATL ACAD SCIENCES, 2019-02-12)
The RAS gene family is frequently mutated in human cancers, and the quest for compounds that bind to mutant RAS remains a major goal, as it also does for inhibitors of protein-protein interactions. We have refined ...
Cloning, purification and structure determination of the HIV integrase-binding domain of lens epithelium-derived growth factor.
(INT UNION CRYSTALLOGRAPHY, 2018-03-01)
Lens epithelium-derived growth factor (LEDGF)/p75 is the dominant binding partner of HIV-1 integrase in human cells. The crystal structure of the HIV integrase-binding domain (IBD) of LEDGF has been determined in the absence ...
Into Deep Water: Optimizing BCL6 Inhibitors by Growing into a Solvated Pocket.
(AMER CHEMICAL SOC, 2021-12-09)
We describe the optimization of modestly active starting points to potent inhibitors of BCL6 by growing into a subpocket, which was occupied by a network of five stably bound water molecules. Identifying potent inhibitors ...
Structural basis of N-Myc binding by Aurora-A and its destabilization by kinase inhibitors.
(NATL ACAD SCIENCES, 2016-11-29)
Myc family proteins promote cancer by inducing widespread changes in gene expression. Their rapid turnover by the ubiquitin-proteasome pathway is regulated through phosphorylation of Myc Box I and ubiquitination by the E3 ...
