  Discovery of Spirofused Piperazine and Diazepane Amides as Selective Histamine-3 Antagonists with in Vivo Efficacy in a Mouse Model of Cognition

  摘要：

  A new series of potent and selective histamine-3 receptor (H3R) antagonists was identified on the basis of an azaspiro[2.5]octane carboxamide scaffold. Many scaffold modifications were largely tolerated, resulting in nanomolar-potent compounds in the H3R functional assay. Exemplar compound 6s demonstrated a selective profile against a panel of 144 secondary pharmacological receptors, with activity at only sigma 2 (62% at 10 mu M). Compound 6s demonstrated free-plasma exposures above the IC50 (similar to 50x) with a brain-to-plasma ratio of similar to 3 following intravenous dosing in mice. At three doses tested in the mouse novel object recognition model (1, 3, and 10 mg/kg s.c.), 6s demonstrated a statistically significant response compared with the control group. This series represents a new scaffold of H-3 receptor antagonists that demonstrates in vivo exposure and efficacy in an animal model of cognition.
