Discovery and optimization of a highly efficacious class of 5-aryl-2-aminopyridines as FMS-like tyrosine kinase 3 (FLT3) inhibitors
摘要:
Based on a putative binding mode of quizartinib (AC220, 1), a potent FMS-like tyrosine kinase 3 (FLT3) inhibitor in Phase III clinical development, we have designed de novo a simpler aminopyridine-based hinge binding motif. Further optimization focusing on maximizing in vivo efficacy and minimizing CYP3A4 time-dependent inhibition resulted in a highly efficacious compound (6s) in tumor xenograft model for further preclinical development.

The acid-catalyzed benzidinerearrangement of diazo compounds is known to involve several rearrangements with the major pathway being a [5,5] sigmatropic rearrangement to provide 4,4′-diaminobiaryls. A limitation of this rearrangement has been poor conversions with pyridyl systems. Herein, we address this long standing issue to furnish hetero-biaryls via a pyridinium salt in the presence of trimethylsilyl

The present invention relates to an organic semiconductor layer and an organic electronic device comprising the same, wherein the organic electronic device comprises an anode, a cathode and at least one organic semiconductor layer, wherein the at least one organic semiconductor layer comprises:
- a metal dopant, and
- a compound represented by the following formula (I):
Chemically diverse fragment hits of focal adhesion kinase (FAK) were discovered by surface plasmon resonance (SPR) screening of our in-house fragment library. Site specific binding of the primary hits was confirmed in a competition setup using a high-affinity ATP-site inhibitor of FAK. Protein crystallography revealed the binding mode of 41 out of 48 selected fragment hits within the ATP-site. Structural comparison of the fragment binding modes with a DFG-out inhibitor of FAK initiated first synthetic follow-up optimization leading to improved binding affinity. (C) 2013 Elsevier Ltd.
