  Discovery of novel VX-809 hybrid derivatives as F508del-CFTR correctors by molecular modeling, chemical synthesis and biological assays

  摘要：

  Cystic fibrosis (CF) is the autosomal recessive disorder most recurrent in Caucasian populations. It is caused by different mutations in the cystic fibrosis transmembrane regulator protein (CFTR) gene, with F508del being the most common. During the last years, small-molecule therapy chosen to contrast CF relied on compounds that correct CFTR misfolding and ER retention (correctors such as VX-809), or defective channel gating (potentiators such as VX-770). Combination therapy with the two series of drugs has been applied, leading to the approval of several multi-drugs such as Orkambi. Despite this, this treatment proved to be only partially effective making the search for novel modulators an urgent need to contrast CF. Recently, we reported compound 2a as reference compound of a series of aminoarylthiazole-VX-809 hybrid derivatives exhibiting promising F508del-CFTR corrector ability. Herein, we report exploring the docking mode of the prototype VX-809 and of 2a in order to derive useful guidelines for the rational design of novel optimized analogues. To demonstrate experimentally their effective F508del-CFTR-binding and rescuing potential, the most promising derivatives had been synthesized and evaluated in biological assays including YFP functional assay on F508del-CFTR CFBE41o-cells, trans epithelial electrical resistance (TEER) and surface plasmon resonance (SPR). This multidisciplinary strategy led to the discovery of a second series of hybrids including 7j and 7m endowed with higher potency than the prototype.

  日期：——

  A novel and efficient visible-light-induced method is developed for the one-pot synthesis of functionalized 2-aminothiazoles from easily accessible active methylene ketone derivatives and different thioureas at room temperature. The mild reaction conditions, green chemistry, straightforward work-up, and high yields of the products make this procedure useful for the construction of 2-aminothiazole derivatives.
