Binding to an Unusual Inactive Kinase Conformation by Highly Selective Inhibitors of Inositol-Requiring Enzyme 1α Kinase-Endoribonuclease.
Colombano, G; Caldwell, JJ; Matthews, TP; Bhatia, C; Joshi, A; et al. (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 ... -
Molecular mechanisms of human IRE1 activation through dimerization and ligand binding.
Joshi, A; Newbatt, Y; McAndrew, PC; Stubbs, M; Burke, R; et al. (IMPACT JOURNALS LLC, 2015-05-30)IRE1 transduces the unfolded protein response by splicing XBP1 through its C-terminal cytoplasmic kinase-RNase region. IRE1 autophosphorylation is coupled to RNase activity through formation of a back-to-back dimer, although ... -
Multiparameter Lead Optimization to Give an Oral Checkpoint Kinase 1 (CHK1) Inhibitor Clinical Candidate: (R)-5-((4-((Morpholin-2-ylmethyl)amino)-5-(trifluoromethyl)pyridin-2-yl)amino)pyrazine-2-carbonitrile (CCT245737).
Osborne, JD; Matthews, TP; McHardy, T; Proisy, N; Cheung, K-MJ; et al. (AMER CHEMICAL SOC, 2016-06-09)Multiparameter optimization of a series of 5-((4-aminopyridin-2-yl)amino)pyrazine-2-carbonitriles resulted in the identification of a potent and selective oral CHK1 preclinical development candidate with in vivo efficacy ... -
The clinical development candidate CCT245737 is an orally active CHK1 inhibitor with preclinical activity in RAS mutant NSCLC and Eµ-MYC driven B-cell lymphoma.
Walton, MI; Eve, PD; Hayes, A; Henley, AT; Valenti, MR; et al. (IMPACT JOURNALS LLC, 2016-01-19)CCT245737 is the first orally active, clinical development candidate CHK1 inhibitor to be described. The IC50 was 1.4 nM against CHK1 enzyme and it exhibited>1,000-fold selectivity against CHK2 and CDK1. CCT245737 potently ...
