Histamine H3 and H4 receptor affinity of branched 3-(1H-imidazol-4-yl)propyl N-alkylcarbamates
摘要:
A series of imidazole-containing (non-)chiral carbamates were tested at human histamine H-3 receptor (H3R). All compounds displayed K-i values below 100 nM. A trend for a stereoselectivity at human H3R was observed for the chiral alpha-branched ligands. Selected compounds were also tested at human histamine H-4 receptor and showed moderate to weak affinities (118-1460 nM). (C) 2009 Elsevier Ltd. All rights reserved.

converted into dihydroconiferyl amine (1G amine) in high selectivity using ammonia gas, by applying our selective amination protocol. Notably also, the crude RCF-oil directly afforded 1G amine in a high 4.6 wt% isolated yield (based on lignin content). Finally it was also shown that the here developed Ni-catalysed heterogeneous catalytic procedure was equally capable of transforming a range of aliphatic linear/cyclic
