Aplysamine-1 and related analogs as histamine H3 receptor antagonists
摘要:
Aplysamine-1 (1), a marine natural product, was synthesized and screened for in vitro activity at the human and rat histamine H-3 receptors. Aplysamine-1 (1) was found to possess a high binding affinity for the human H3 receptor (K-i = 30 +/- 4nM). Synthetic analogs of 1, including des-bromoaplysamine-1 (10) and dimethyl-{2-[4-(3-piperidin-1-yl-propoxy)-phenyl]-ethyl}-amine (13), were potent H-3 antagonists. (c) 2005 Elsevier Ltd.
