Novel 2-methyl-5-quinolinyl-1-piperazinylalkyl-3,4-dihydro-2H-1,4-benzoxazin-3-ones showing high affinities for the 5-HT(1A/1B/1D) receptors coupled with potent 5-HT reuptake inhibitory activity have been discovered. This is the first report describing docking of the lead compound 6-{2-[4-(2-methyl-5-quinolinyl)-1-piperazinyl]ethyl}-2H-1,4-benzoxazin-3(4H)-one 1, into a model of the 5-HT transporter and the 5-HT(1A) receptor model.

Antinociceptive effect of (-)-epicatechin in inflammatory and neuropathic pain in rats.
Behav Pharmacol
April 2018
Section of Postgraduate Studies and Research, Escuela Superior de Medicina, Instituto Politecnico Nacional.
The aim of this study was to investigate the antinociceptive potential of (-)-epicatechin and the possible mechanisms of action involved in its antinociceptive effect. The carrageenan and formalin tests were used as inflammatory pain models. A plethysmometer was used to measure inflammation and L5/L6 spinal nerve ligation as a neuropathic pain model.

Hence, in this work, the aim is to provide an appropriate conceptual framework of serotonergic markers associated with neural activity and memory. Serotonin (5-hydroxytryptamine [5-HT]) has multiple pharmacological tools, well-characterized downstream signaling in mammals' species, and established 5-HT neural markers showing new insights about memory functions and dysfunctions, including receptors (5-HT1A/1B/1D, 5-HT2A/2B/2C, and 5-HT3-7), transporter (serotonin transporter [SERT]) and volume transmission present in brain areas involved in memory.

Serotonin (5-HT) participates in pain modulation by interacting with different 5-HT receptors. The role of 5-HT5A receptor in neuropathic pain has not previously studied. The purpose of this study was to investigate: A) the role of 5-HT5A receptors in rats subjected to spinal nerve injury; B) the expression of 5-HT5A receptors in dorsal spinal cord and dorsal root ganglia (DRG).

5-hydroxytryptamine 1 (5-HT1) receptor blockade in combination with serotonin reuptake inhibition may provide a more rapid elevation of synaptic 5-HT compared to serotonin reuptake alone, by blocking the inhibitory effect of 5-HT1 receptor activation on serotonin release. GSK588045 is a novel compound with antagonist activity at 5-HT1A/1B/1D receptors and nanomolar affinity for the serotonin transporter, which was in development for the treatment of depression and anxiety. Here we present the results of an in vivo assessment of the relationship between plasma exposure and 5-HT1A receptor occupancy.

The serotonergic system is involved in pathomechanisms of both epilepsy and neuropathic pain. So far, participation in the epileptogenesis and maintenance of epilepsy was proved for 5-HT1A, 5-HT2C, 5-HT3, 5-HT4 and 5-HT7 receptors as well as 5-HTT serotonin transporter. Depending on the receptor type or its localization, its stimulation may increase or decrease neuronal excitability.
