  Design, Synthesis, and Structure−Activity Relationships of Acetylene-Based Histamine H₃ Receptor Antagonists

  摘要：

  New, potent, and selective histamine H-3 receptor antagonists have been synthesized by employing the use of (1) an appropriately positioned nonpolar acetylene spacer group, (2) either a two-carbon straight chain linker or a conformationally restricting trans-cyclopropane ring between the C-4 position of an imidazole headgroup and the acetylene spacer, and (3) a Topliss operational scheme for side-chain substitution for optimizing the hydrophobic domain. Compounds 9-18 are examples synthesized with the two-carbon straight chain linker, whereas 26-31 are analogues prepared by incorporation of the trans-(+/-)-cyclopropane at the C-4 position of an imidazole headgroup. Synthesis of both the (1R,2R)- and (1S,2S)-cyclopropyl enantiomers of the most potent racemic compound 31 (K-i = 0.33 +/- 0.13 nM) demonstrated a stereopreference in H-3 receptor binding affinity for the (1R,2R) enantiomer 32 (K-i = 0.18 +/- 0.04 nM) versus the (1S,2S) enantiomer 33 (K-i = 5.3 +/- 0.5 nM). (1R,2R)-4-(2-(5,5-Dimethylhex-1-ynyl)cyclopropyl)- imidazole (32) is one of the most potent histamine H-3 receptor antagonists reported to date.
