Design, synthesis, and pharmacological characterization of N- and O-substituted 5,6,7,8-tetrahydro-4H-isoxazolo[4,5-d]azepin-3-ol analogues: novel 5-HT(2A)/5-HT(2C) receptor agonists with pro-cognitive properties.[Pubmed:23301527]
J Med Chem. 2013 Feb 14;56(3):1211-27.
The isoxazol-3-one tautomer of the bicyclic isoxazole, 5,6,7,8-tetrahydro-4H-isoxazolo[4,5-d]azepin-3-ol (THAZ), has previously been shown to be a weak GABA(A) and glycine receptor antagonist. In the present study, the potential in this scaffold has been explored through the synthesis and pharmacological characterization of a series of N- and O-substituted THAZ analogues. The analogues N-Bn-THAZ (3d) and O-Bn-THAZ (4d) were found to be potent agonists of the human 5-HT(2A) and 5-HT(2C) receptors. Judging from an elaborate pharmacological profiling at numerous other CNS targets, the 3d analogue appears to be selective for the two receptors. Administration of 3d substantially improved the cognitive performance of mice in a place recognition Y-maze model, an effect fully reversible by coadministration of the selective 5-HT(2C) antagonist SB242084. In conclusion, as novel bioavailable cognitive enhancers that most likely mediate their effects through 5-HT(2A) and/or 5-HT(2C) receptors, the isoxazoles 3d and 4d constitute interesting leads for further medicinal chemistry development.
Involvement of 5-HT2A receptors in the elevation of rat serum corticosterone concentrations by quipazine and MK-212.[Pubmed:8891601]
Eur J Pharmacol. 1996 Sep 12;311(2-3):207-11.
The possible involvement of 5-HT2A or 5-HT2C receptors in the elevation of serum corticosterone in rats by quipazine (2-(1-piperazinyl)quinoline maleate) and MK-212 (6-chloro-(1-piperazinyl)pyrazine), direct-acting 5-HT receptor agonists, was investigated by the use of two newly available receptor antagonists, SB 200646A (N-(1-methyl-5-indolyl)-N'-(3-pyridyl)urea) and MDL 100,907 (R-(+)-alpha-(2,3-dimethoxyphenyl)-1-[2-(4-fluorophenylethyl)]- 4-piperidinemethanol). MDL 100,907 blocked the increase in serum corticosterone elicited by quipazine and MK-212 with ED50 values of 0.0028 and 0.0027 mg/kg, s.c., respectively. In contrast, SB 200646A only partially antagonized the serum corticosterone concentration increases by quipazine and MK-212 even at the highest dose tested, 40 mg/kg, i.p. Because published data show the affinities of MDL 100,907 and SB 200646A for 5-HT2C receptors to be nearly identical, whereas the affinity of MDL 100,907 for 5-HT2A receptors is 17500-fold higher than that of SB 200646A, our findings suggest that 5-HT2A receptors rather than 5-HT2C receptors mediate the serum corticosterone increases by both quipazine and MK-212.
Relative efficacies of piperazines at the phosphoinositide hydrolysis-linked serotonergic (5-HT-2 and 5-HT-1c) receptors.[Pubmed:3039120]
J Pharmacol Exp Ther. 1987 Aug;242(2):552-7.
Serotonin (5-HT)-stimulated phosphoinositide hydrolysis is mediated by the 5-HT-2 receptor in rat cerebral cortex and by the 5-HT-1c receptor in rat choroid plexus. These systems were used to determine relative efficacies of piperazine derivatives at the 5-HT-2 and 5-HT-1c receptors. Both quipazine and 6-chloro-2-[1-piperazinyl]-pyrazine (MK-212) stimulated phosphoinositide hydrolysis in cerebral cortex, and these effects were blocked by ketanserin. The maximum responses to these agonists were 80% of the maximum response to 5-HT. m-Trifluoromethylphenylpiperazine (TFMPP), m-chlorophenylpiperazine (MCPP) and 1-(1-naphthyl)-piperazine (1-NP) did not stimulate phosphoinositide hydrolysis in cerebral cortex at concentrations that blocked the effect of 5-HT. In the choroid plexus, TFMPP and MCPP, as well as MK-212 and quipazine, increased phosphoinositide hydrolysis and mianserin blocked these effects. MK-212 had an efficacy which was equal to that of 5-HT, whereas quipazine, MCPP and TFMPP were partial agonists in the choroid plexus. 1-NP did not stimulate phosphoinositide hydrolysis in choroid plexus but completely blocked the effect 5-HT. On the basis of these data, we conclude that quipazine and MK-212 are partial agonists at 5-HT-2 receptors in cerebral cortex, whereas 1-NP, TFMPP and MCPP are pure antagonists of the cortical 5-HT-2 receptor. However, TFMPP and MCPP as well as quipazine and MK-212 are agonists at the 5-HT-1c receptor, while 1-NP is a pure antagonist of the 5-HT-1c receptor in choroid plexus.
