  N-Alkenyl and cycloalkyl carbamates as dual acting histamine H3 and H4 receptor ligands

  摘要：

  Previous studies have shown that several imidazole derivatives posses affinity to histamine H-3 and H-4 receptors. Continuing our study on structural requirements responsible for affinity and selectivity for H-3/H-4 receptor subtypes, two series of 3-(1H-imidazol-4-yl) propyl carbamates were prepared: a series of unsaturated alkyl derivatives (1-9) and a series possessing a cycloalkyl group different distances to the carbamate moiety (10-13). The compounds were tested for their affinities at the human histamine H3 receptor, stably expressed in CHO-K1 cells. Compounds 1, 2, 5-7, 10-13 were investigated for their affinities at the human histamine H-4 receptor co-expressed with G alpha(i2) and G beta(1)gamma(2) subunits in Sf9 cells. To expand the pharmacological profile, compounds were further tested for their H3 receptor antagonist activity on guinea pig ileum and in vivo after oral administration to mice. All tested compounds exhibited good affinity for the human histamine H-3 receptor with K-i values in the range from 14 to 194 nM. All compounds were active in vivo after peroral administration (p.o.) to Swiss mice, thus demonstrating their ability to cross the blood-brain barrier. The most potent H-3 receptor ligand of these series was compound 5, 3-(1H-imidazol-4-yl) propyl pent-4-enylcarbamate with the highest affinity (K-i = 14 nM). Additionally, compound 3 showed remarkable central nervous system (CNS) H3R activity, increasing the N-tau-methylhistamine levels in mice with an ED50 value of 0.55 mg/kg, p.o. evidencing therefore, a twofold increase of inverse agonist/antagonist potency compared to the reference inverse agonist/antagonist thioperamide. In this study, the imidazole propyloxy carbamate moiety was kept constant. The different lipophilic moieties connected to the carbamate functionality in the eastern part of the molecule had a range of influences on the human H-4 receptor affinity (154-1326 nM).

  Ligands targeting central histamine H-3 receptors (H(3)Rs) for epilepsy might be a promising therapeutic approach. Therefore, the previously described and structurally strongly related imidazole-based derivatives belonging to carbamate class with high H3R in vitro affinity, in-vivo antagonist potency, and H3R selectivity profile were investigated on their anticonvulsant activity in maximal electroshock (MES)-induced and pentylenetetrazole (PTZ)-kindled seizure models in Wistar rats. The effects of systemic injection of H3R ligands 1-13 on MES-induced and PTZ-kindled seizures were screened and evaluated against the reference antiepileptic drug (AED) Phenytoin (PHT) and the standard histamine H3R inverse agonist/antagonist Thioperamide (THP) to determine their potential as new antiepileptic drugs. Following administration of the H3R ligands 1-13 (5, 10 and 15 mg/kg, ip) there was a significant dose dependent reduction in MES-induced seizure duration. The protective action observed for the pentenyl carbamate derivative 4, the most protective H3R ligand among 1-13, was significantly higher (P<0.05) than that of standard H3R antagonist THP, and was reversed when rats were pretreated with the selective H3R agonist R-(alpha)-methyl-histamine (RAMH) (10 mg/kg), or with the CNS penetrant H1R antagonist Pyrilamine (PYR) (10 mg/kg). In addition, subeffective dose of H3R ligand 4 (5 mg/kg, ip) significantly potentiated the protective action in rats pretreated with PHT (5 mg/kg, ip), a dose without appreciable protective effect when given alone. In contrast, pretreatment with H3R ligand 4 (10 mg/kg ip) failed to modify PTZ-kindled convulsion, whereas the reference drug PHT was found to fully protect PTZ-induced seizure. These results indicate that some of the investigated imidazole-based H3R ligands 1-13 may be of future therapeutic value in epilepsy. (C) 2013 Elsevier Ltd. All rights reserved.
