The optimization of aminooxadiazoles as orally active inhibitors of Cdc7
摘要:
A series of aminooxadiazoles was optimized for inhibition of Cdc7. Early lead isoquinoline 1 suffered from modest cell potency (cellular IC50 = 0.71 mu M measuring pMCM2), low selectivity against structurally related kinases, and high IV clearance in rats (CL = 18 L/h/kg). Extensive optimization resulted in azaindole 26 (Cdc7 IC50 = 1.1 nM, pMCM2 IC50 = 32 nM) that demonstrated robust lowering of pMCM2 in a mouse pharmacodynamic (PD) model when dosed orally. Modifications to improve the pharmacokinetic profile of this series were guided by trapping experiments with glutathione in rat hepatocytes. (C) 2013 Elsevier Ltd. All rights reserved.
Azole-based inhibitors of AKT/PKB for the treatment of cancer
摘要:
Through a combination of screening and structure-based rational design, we have discovered a series of N-1-(5-(heterocyclyl)-thiazol-2-yl)-3-(4-trifluoromethylphenyl)-1,2-propanediamines that were developed into potent ATP competitive inhibitors of AKT. Studies of linker strand-binding adenine isosteres identified SAR trends in potency and selectivity that were consistent with binding interactions observed in structures of the inhibitors bound to AKT1 and to the counter-screening target PKA. One compound was shown to have acceptable pharmacokinetic properties and to be a potent inhibitor of AKT signaling and of in vivo xenograft tumor growth in a preclinical model of glioblastoma.

We report here the discovery and structure-guided optimization of a novelseries of AKT kinase inhibitors. Based on docking studies for the predicted active bound-conformation of 2, a potent series of N-substituted-5-(isoquinolin-6-yl)-1,3,4-thiadiazol-2-amines was developed. Compounds in the series achieve AKT pathway inhibition in cancer cells, as measured by inhibition of pathway proteins pGSK and
