  Design, Synthesis, and Structure−Activity Relationships of Novel 2-Substituted Pyrazinoylguanidine Epithelial Sodium Channel Blockers:  Drugs for Cystic Fibrosis and Chronic Bronchitis

  摘要：

  Amiloride (1), the prototypical epithelial sodium channel (ENaC) blocker, has been administered with limited success as aerosol therapy for improving pulmonary function in patients with the genetic disorder cystic fibrosis. This study was conducted to synthesize and identify more potent, less reversible ENaC blockers, targeted for aerosol therapy and possessing minimal systemic renal activity. A series of novel 2-substituted acylguanidine analogues of amiloride were synthesized and evaluated for potency and reversibility on bronchial ENaC. All compounds tested were more potent and less reversible at blocking sodium-dependent shortcircuit current than amiloride. Compounds 30-34 showed the greatest potency on ENaC with IC50 values below 10 nM. A regioselective difference in potency was found (compounds 30, 39, and 40), whereas no stereospecific (compounds 33, 34) difference in potency on ENaC was displayed. Lead compound 32 was 102-fold more potent and 5-fold less reversible than amiloride and displayed the lowest IC50 value ever reported for an ENaC blocker.

  A new catalytic reaction for the synthesis of pyrrolidine derivatives is presented. The method implies the coupling of N‐Boc‐protected alkynamine derivatives and appropriate alkenes or alkynes in a process catalysed by a platinum/triflic acid catalytic binary system. This reaction is believed to proceed through a cascade process implying an initial platinum‐catalysed cycloisomerization of the alkynamine

  A gold/BF3 catalytic system promotes the transformation of simple 3‐butynamines and 2‐(hydroxymethyl)phenol derivatives into cyclic enamines and ortho‐quinone methide derivatives. The subsequent formal [4+2]‐cyclization reaction between these two intermediates gives rise to hexahydrochromeno[2,3‐b]pyrrole derivatives.

  diene derivatives for reactions with different dienophiles. Herein, we describe the behavior of ortho‐alkynylsalicylaldehydes, a particular case of ortho‐alkynylbenzaldehydes. The gold‐catalyzed cycloisomerization of ortho‐alkynylsalicylaldehydes delivers an unusual heterodiene derivative that reacts with electron‐rich alkenes through a formal [4+2] cycloaddition. In this reaction, both the diene and
