Identification of a novel 3,5-disubstituted pyridine as a potent, selective, and orally active inhibitor of Akt1 kinase
摘要:
Based on lead compounds 2 and 3 a series of 3,5-disubstituted pyridines have been designed and evaluated for inhibition of AKT/PKB. Modifications at the 3 position of the pyridine ring led to a number of potent compounds with improved physical properties, resulting in the identification of 11g as a promising, orally active Akt inhibitor. The synthesis, structure-activity relationship studies, and pharmacokinetic data are presented in this paper. (c) 2006 Elsevier Ltd. All rights reserved.

A pyrrolopyridinyl thiophene carboxamide 7 was discovered as a tractable starting point for a lead optimization effort in an AKT kinase inhibition program. SAR studies aided by a co-crystal structure of 7 in AKT2 led to the identification of AKT inhibitors with subnanomolar potency. Representative compounds showed antiproliferative activity as well as inhibition of phosphorylation of the downstream target GSK3 beta. (c) 2009 Elsevier Ltd. All rights reserved.
The identification of 8,9-dimethoxy-5-(2-aminoalkoxy-pyridin-3-yl)-benzo[c][2,7]naphthyridin-4-ylamines as potent inhibitors of 3-phosphoinositide-dependent kinase-1 (PDK-1)

A series of 8,9-dimethoxy-5-(2-aminoalkoxy-pyridin-3-yl)-benzo[c] [2,7]naphthyridin-4-ylamine-based inhibitors of 3-phosphoinositide-dependent kinase-1 (PDK-1) has been identified. Several examples appear to be potent and relatively selective inhibitors of PDK-1 over the related AGC kinases PKA, PKB/AKT, and p70S6K. The introduction of a stereochemical center beside the amino substituent on the aminoalkoxy-side chain had little effect upon the inhibitory activity against these enzymes, and X-ray crystallographic analyses of a representative pair of enantiomeric inhibitors bound to the active site of PDK-1 revealed comparable binding modes for each enantiomer.
