  摘要：

  Compound 8a (BMS-191011), an opener of the cloned large-conductance, Ca2+-activated potassium (maxi-K) channel, demonstrated efficacy in in vivo stroke models, which led to its nomination as a candidate for clinical evaluation. Its maxi-K channel opening properties were consistent with its structural topology, being derived by combining elements from other known maxi-K openers. However, 8a suffered from poor aqueous solubility, which complicated elucidation of SAR during in vitro evaluation. The activity of 8a in in vivo stroke models and studies directed toward improving its solubility are reported herein. Enhanced solubility was achieved by appending heterocycles to the 8a scaffold, and a notable observation was made that inclusion of a simple amino group (anilines 8k and 8l) yielded excellent in vitro maxi-K ion channel opening activity and enhanced brain-to-plasma partitioning compared to the appended heterocycles.

  Novel compounds of Formula 1 are useful to treat disorders responsive to openers of the large conductance calcium-activated potassium channels: wherein “Het” is one of a select group of heterocyclic moieties; Z is independently for each occurrence selected from O or S; Ra, Rb and Rc each are independently selected from hydrogen, halogen, OH, CF3, NO2, or provided Rc is not hydrogen; and when Ra and Rb are hydrogen, Rc may be a heterocyclic moiety selected from the group consisting of imidazol-1-yl, morpholinomethyl, N-methylimidazol-2-yl, and pyridin-2-yl; Rd and Re each are independently selected from hydrogen, halogen, CF3, NO2 or imidazol-1-yl; m, n and p each are independently selected from an integer of 0 or 1; and Rf and Rg each are independently hydrogen; C1-4 alkyl; or Rf and Rg, taken together with the nitrogen atom to which they are attached, is a heterocyclic moiety selected from the group consisting of N-methylpiperazine, morpholine, thiomorpholine, N-benzylpiperazine and imidazolinone.
