  Discovery of the 1,7-diazacarbazole class of inhibitors of checkpoint kinase 1

  摘要：

  Checkpoint kinase 1 (ChK1) is activated in response to DNA damage, acting to temporarily block cell cycle progression and allow for DNA repair. It is envisaged that inhibition of ChK1 will sensitize tumor cells to treatment with DNA-damaging therapies, and may enhance the therapeutic window. High throughput screening identified carboxylate-containing diarylpyrazines as a prominent hit series, but with limited biochemical potency and no cellular activity. Through a series of SAR investigations and X-ray crystallographic analysis the critical role of polar contacts with conserved waters in the kinase back pocket was established. Structure-based design, guided by in silico modeling, transformed the series to better satisfy these contacts and the novel 1,7-diazacarbazole class of inhibitors was discovered. Here we present the genesis of this novel series and the identification of GNE-783, a potent, selective and orally bioavailable inhibitor of ChK1. (C) 2014 Elsevier Ltd. All rights reserved.

  Chemoenzymatic synthesis of the two enantiomers of 7-azatryptophan

  摘要：

  7-Azatryptophan is an unnatural alpha-amino acid with a very potent fluorescent activity. It is used as a vehicle for probing the structure and dynamics of proteins and peptides. Diastereoselective alkylation, diastereoselective protonation and enzymatic resolution have been tested for preparing enantiomerically pure 7-azatryptophan. (C) 1998 Elsevier Science Ltd.

  Thioesters, thiocarbamates, thiocarbazates, semithiocarbazates, peptides, aza-amino acid conjugates, and azapeptides; and a chemoselective and site-specific functionalization protocol of protected thiocarbazates and semithiocarbazates are described. The protocol features the use of Mitsunobu reaction to alkylate specifically the nitrogen atom close to the acylthiol moiety with alcohols to produce protected mono-substituted thiocarbazates that can be stored for months, activated under mild conditions at low temperature using halonium reagents and integrated orthogonally to make substituted semicarbazides that can be used, e.g., as synthons in synthesis of aza-amino acid conjugates, azapeptides and other peptidomimetics. Methods for preparing and using ureases, carbazides, semicarbazides, beta-peptides, azapeptides, and other peptidomimetics and azapeptide conjugates, and uses of ureases, carbazides, semicarbazides, beta-peptides, azapeptides in drug discovery, diagnosis, inhibition, prevention and treatment of diseases are also described.
