the 3‐amino‐1‐propanol moiety common to the many previously described non‐imidazole H3 ligands. Detailed structure‐activity studies revealed that 1‐(2‐benzofuranylmethyl)‐ 5c (pA2 = 8.47 ± 0.05) and 1‐(3‐benzofuranylmethyl)‐4‐[5‐(N‐methyl‐N‐propyl)pentyloxy]piperidine 5d (pA2 = 8.15 ± 0.07) exhibit high potency for the H3 histamine receptor. In addition, the potency of selected 1‐[(N‐substituted‐N‐
4-Hydroxypiperidines and Their Flexible 3-(Amino)propyloxy Analogues as Non-Imidazole Histamine H3 Receptor Antagonist: Further Structure–Activity Relationship Exploration and In Vitro and In Vivo Pharmacological Evaluation
Additionally, the most active compound in this series of non-imidazole H3 receptor antagonists/inverse agonists, i.e., ADS-003, was evaluated for its affinity to the recombinant rat and human histamine H3 receptors transiently expressed in HEK-293T cells. It was shown that ADS-003, given parenterally for 5 days, reduced the food intake of rats, as well as changed histamine and noradrenaline concentrations in
