Binding of serotonin and N1-benzenesulfonyltryptamine-related analogs at human 5-HT6 serotonin receptors: receptor modeling studies.[Pubmed:18201064]

J Med Chem. 2008 Feb 14;51(3):603-11.

A population of 100 graphics models of the human 5-HT6 serotonin receptor was constructed based on the structure of bovine rhodopsin. The endogenous tryptamine-based agonist serotonin (5-HT; 1) and the benzenesulfonyl-containing tryptamine-derived 5-HT6 receptor antagonist MS-245 (4a) were automatically docked with each of the 100 receptor models using a genetic algorithm approach. Similar studies were conducted with the more selective 5-HT6 receptor agonist EMDT (5) and optical isomers of EMDT-related analog 8, as well as with optical isomers of MS-245 (4a)-related and benzenesulfonyl-containing pyrrolidine 6 and aminotetralin 7. Although associated with the same general aromatic/hydrophobic binding cluster, 5-HT (1) and MS-245 (4a) were found to preferentially bind with distinct receptor conformations, and did so with different binding orientations (i.e., poses). A 5-HT pose/model was found to be common to EMDT (5) and its analogs, whereas that identified for MS-245 (4a) was found common to benzenesulfonyl-containing compounds. Specific amino acid residues were identified that can participate in binding, and evaluation of a sulfenamide analog of MS-245 indicates for the first time that the presence of the sulfonyl oxygen atoms enhances receptor affinity. The results indicate that the presence or absence of an N1-benzenesulfonyl group is a major determinant of the manner in which tryptamine-related agents bind at 5-HT6 serotonin receptors.

Effect of the 5-HT(6) serotonin antagonist MS-245 on the actions of (-)nicotine.[Pubmed:16950502]

Pharmacol Biochem Behav. 2006 Sep;85(1):170-7.

The 5-HT(6) serotonin receptor antagonist MS-245 neither substitutes for nor antagonizes the discriminative stimulus effects of (-)nicotine. However, MS-245 was shown to enhance the potency of (-)nicotine in Sprague-Dawley rats trained to discriminate 0.6 mg/kg of (-)nicotine from saline vehicle in a typical two-lever drug discrimination paradigm such that a combination of MS-245 (5.0 mg/kg) plus the ED(50) dose of (-)nicotine caused the animals to respond as if they had received the training dose of (-)nicotine. MS-245 also potentiated the hypolocomotor actions, but not the antinociceptive effects, of (-)nicotine in mice. The results suggest possible involvement of serotonin-regulated signaling mechanisms in certain behavioral effects of nicotine.

2-Substituted tryptamines: agents with selectivity for 5-HT(6) serotonin receptors.[Pubmed:10715164]

J Med Chem. 2000 Mar 9;43(5):1011-8.

Several 2-alkyl-5-methoxytryptamine analogues were designed and prepared as potential 5-HT(6) serotonin agonists. It was found that 5-HT(6) receptors accommodate small alkyl substituents at the indole 2-position and that the resulting compounds can bind with affinities comparable to that of serotonin. In particular, 2-ethyl-5-methoxy-N, N-dimethyltryptamine (8) binds with high affinity at human 5-HT(6) receptors (K(i) = 16 nM) relative to 5-HT (K(i) = 75 nM) and was a full agonist, at least as potent (8: K(act) = 3.6 nM) as serotonin (K(act) = 5.0 nM), in activating adenylate cyclase. Compound 8 displays modest affinity for several other populations of 5-HT receptors, notably h5-HT(1A) (K(i) = 170 nM), h5-HT(1D) (K(i) = 290 nM), and h5-HT(7) (K(i) = 300 nM) receptors, but is otherwise quite selective. Compound 8 represents the first and most selective 5-HT(6) agonist reported to date. Replacing the 2-ethyl substituent with a phenyl group results in a compound that retains 5-HT(6) receptor affinity (i.e., 10: K(i) = 20 nM) but lacks agonist character. 2-Substituted tryptamines, then, might allow entry to a novel class of 5-HT(6) agonists and antagonists.
