We previously reported a novel series of 1H-pyrazolo[3,4-c]pyridinederivatives and the identification of compound 4b as a highly potent GPR119 agonist. However, the advancement of preclinical evaluations of compound 4b is expected to be difficult because of the compound’s significantly poor aqueous solubility (0.71 μM at pH6.8). In this article, we describe the further optimization of compound 4b
我们先前报道了一系列新型的1 H-吡唑并[3,4- c ]吡啶衍生物,并将化合物4b鉴定为高效GPR119激动剂。但是,由于该化合物的水溶性差(在pH6.8下为0.71μM),因此很难进行化合物4b的临床前评估。在本文中,我们描述了化合物4b的进一步优化,重点是提高其水溶性。优化中央间隔基,左手的芳基和右手的哌啶N-封端基团导致鉴定出强效的GPR119激动剂3 H- [1,2,3]三唑[4,5- c ]]吡啶衍生物32o,具有改善的溶解度(在pH6.8下为15.9μM)。
Importance of Binding Site Hydration and Flexibility Revealed When Optimizing a Macrocyclic Inhibitor of the Keap1–Nrf2 Protein–Protein Interaction
Upregulation of the transcription factor Nrf2 by inhibition of the interaction with its negative regulator Keap1 constitutes an opportunity for the treatment of disease caused by oxidative stress. We report a structurally unique series of nanomolar Keap1inhibitors obtained from a natural product-derived macrocyclic lead. Initial exploration of the structure-activity relationship of the lead, followed
