Structural basis for translocation by AddAB helicase-nuclease and its arrest at χ sites.
(NATURE PUBLISHING GROUP, 2014-04-17)
In bacterial cells, processing of double-stranded DNA breaks for repair by homologous recombination is dependent upon the recombination hotspot sequence χ (Chi) and is catalysed by either an AddAB- or RecBCD-type ...
Redox Signaling by the RNA Polymerase III TFIIB-Related Factor Brf2.
(CELL PRESS, 2015-12-03)
TFIIB-related factor 2 (Brf2) is a member of the family of TFIIB-like core transcription factors. Brf2 recruits RNA polymerase (Pol) III to type III gene-external promoters, including the U6 spliceosomal RNA and selenocysteine ...
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 ...
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 ...
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 ...
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 ...
High-resolution cryo-EM proteasome structures in drug development.
(INT UNION CRYSTALLOGRAPHY, 2017-06-01)
With the recent advances in biological structural electron microscopy (EM), protein structures can now be obtained by cryo-EM and single-particle analysis at resolutions that used to be achievable only by crystallographic ...
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 ...
Synthesis and profiling of a 3-aminopyridin-2-one-based kinase targeted fragment library: Identification of 3-amino-5-(pyridin-4-yl)pyridin-2(1H)-one scaffold for monopolar spindle 1 (MPS1) and Aurora kinases inhibition.
(PERGAMON-ELSEVIER SCIENCE LTD, 2018-07-15)
Screening a 3-aminopyridin-2-one based fragment library against a 26-kinase panel representative of the human kinome identified 3-amino-5-(1-methyl-1H-pyrazol-4-yl)pyridin-2(1H)-one (2) and 3-amino-5-(pyridin-4-yl)pyridi ...
Structural Basis for Auto-Inhibition of the NDR1 Kinase Domain by an Atypically Long Activation Segment.
(CELL PRESS, 2018-08-07)
The human NDR family kinases control diverse aspects of cell growth, and are regulated through phosphorylation and association with scaffolds such as MOB1. Here, we report the crystal structure of the human NDR1 kinase ...
