Heterocyclic replacement of the central phenyl core of diamine-based histamine H3 receptor antagonists
摘要:
A series of small molecules consisting of a heterocyclic core flanked by two basic functionalities were synthesized and screened for in vitro affinity at the human histamine H-3 receptor (hH(3)R). Nine of the twenty-eight compounds tested were found to possess a hH(3)R K-i of less than 5 nM and consisted of a diverse range of central hetero-aromatic linkers (pyridine, pyrazine, oxazole, isoxazole, thiazole, furan, thiophene, and pyrrole). One member of this series, (4-isopropyl-piperazin-1-yl)-(6-piperidin-1-ylmethyl-pyridin-3-yl)-methanone (37), was found to be a high affinity, selective antagonist that crosses the blood-brain barrier and occupies H-3 receptors after oral administration in the rat.

A flow‐based synthesis of diversely functionalized indolizines and their aza‐analogues is described. These drug‐like heterocycles were generated via a tandem Sonogashira/cycloisomerization sequence, starting from widely available 2‐bromopyridines and alkynes, employing a simple catalyst system together with 1,8‐diazabicyclo[5.4.0]undec‐7‐ene (DBU) as base. The use of flow technology allows a straightforward
