  摘要：

  The FK506 binding protein 51 (FKBP51) is an appealing drug target due to its role in several diseases such as depression, anxiety, chronic pain and obesity. Towards this, selectivity versus the close homolog FKBP52 is essential. However, currently available FKBP51‐selective ligands such as SAFit2 are too large and lack drug‐like properties. Here, we present a structure activity relationship (SAR) analysis of the pipecolic ester moiety of SAFit1 and SAFit2, which culminated in the discovery of the 1,4‐pyrazolyl derivative 23d, displaying a binding affinity of 0.077 µM for FKBP51, reduced molecular weight (541.7 g/mol), lower hydrophobicity (cLogP = 3.72) and higher ligand efficiency (LE = 0.25). Cocrystal structures revealed the importance of the 1,4‐ and 1,3,4‐ substitution patterns of the pyrazole ring versus the 1,4,5 arrangement.

  The discovery and optimization of a new class of bacterial topoisomerase (DNA gyrase and topoisomerase IV) inhibitors binding in the ATP domain are described. A fragment molecule, 1-ethyl-3-(2-pyridyl)urea, provided sufficiently potent enzyme inhibition (32 μM) to prompt further analogue work. Acids and acid isosteres were incorporated at the 5-pyridyl position of this fragment, bridging to a key asparagine

  node for oncogenic cell-signaling cascades including the PD-L1/PD-1 pathway. Consequently, SHP2 has emerged as a compelling target for novel anti-cancer agents. Replacing one of phenyl ring in PTP1B inhibitor 1 with heterocyclic ring led to a series of heterocyclic bis-aryl amide derivatives. The representative compound 7b displayed SHP2 inhibitory activity with IC50 of 2.63 ± 0.08 μM, exhibited about
