Nociceptin/orphanin FQ (N/OFQ) and N/OFQ peptide (NOP) receptor are expressed and distributed in various regions such as central nervous system (CNS), peripheral nervous system, immune system, and peripheral tissues. N/OFQ and NOP receptor have important
New synthesis of tic-hydantoins sigma-1 ligands and pharmacological evaluation on cocaine-induced stimulant effects
Toussaint,Debreu-Fontaine,Maurice,Melnyk
experimental part, p. 355 - 373 (2011/09/13)
Activation of the newly identified σ1 chaperone protein is involved in several aspects of the psychostimulant and addictive effects of cocaine. The development of ligands that selectively target the σ1 protein may lead to putative potent anti-cocaine agen

A mild and general strategy for the synthesis of 2-substituted 4-amino-1,2,4,5-tetrahydro-2-benzazepine-3-ones is described. The seven-membered lactam is prepared by intramolecular amide bond formation from the intermediate amino acid, which is obtained e
CCK2 receptor antagonists containing the conformationally constrained phenylalanine derivatives, including the new amino acid Xic

The conformationally constrained analogues of phenylalanine, tetrahydroisoquinoline-3-carboxylic acid (Tic), Sic, Hic and Nic, and the new amino acid Xic have been incorporated into a potent and highly selective cholecystokinin-2 (CCK2) receptor antagonist (2) in place of the phenylalanine residue, producing compounds 15a-e. High selectivities for CCK2 over CCK1 were observed for compounds 15a-e. The in vitro profile of the analogue containing the Nic residue (15d) was identical to that of compound 2, whereas the alternative conformational constraints resulted in a significant loss of affinity. The apparent advantage of Nic in the context of these CCK2 ligands was subsequently demonstrated to be statistically significant.
Synthesis and structure-activity relationships of potential anticonvulsants based on 2-piperidinecarboxylic acid and related pharmacophores
Ho, Bin,Michael Crider,Stables, James P
, p. 265 - 286 (2007/10/03)
Using N-(2,6-dimethyl)phenyl-2-piperidinecarboxamide (1) and N-(α-methylbenzyl)-2-piperidinecarboxamide (2) as structural leads, a variety of analogues were synthesised and evaluated for anticonvulsant activity in the MES test in mice. In the N-benzyl series, introduction of 3-Cl, 4-Cl, 3,4-Cl2, or 3-CF3 groups on the aromatic ring led to an increase in MES activity. Replacement of the α-methyl group by either i-Pr or benzyl groups enhanced MES activity with no increase in neurotoxicity. Substitution on the piperidine ring nitrogen led to a decrease in MES activity and neurotoxicity, while reduction of the amide carbonyl led to a complete loss of activity. Movement of the carboxamide group to either the 3- or 4-positions of the piperidine ring decreased MES activity and neurotoxicity. Incorporation of the piperidine ring into a tetrahydroisoquinoline or diazahydrinone nucleus led to increased neurotoxicity. In the N-(2,6-dimethyl)phenyl series, opening of the piperidine ring between the 1- and 6-positions gave the active norleucine derivative 75 (ED50 = 5.8 mg kg-1, TD50 = 36.4 mg kg-1, PI = 6.3). Replacement of the piperidine ring of 1 by cycloalkane (cyclohexane, cyclopentane, and cyclobutane) resulted in compounds with decreased MES activity and neurotoxicity, whereas replacement of the piperidine ring by a 4-pyridyl group led to a retention of MES activity with a comparable PI. Simplification of the 2-piperidinecarboxamide nucleus of 1 into a glycinecarboxamide nucleus led to about a six-fold decrease in MES activity. The 2,6-dimethylanilides were the most potent compounds in the MES test in each group of compounds evaluated, and compounds 50 and 75 should be useful leads in the development of agents for the treatment of tonic-clonic and partial seizures in man.
