Summary
Researchers explored N-substituted tryptamines for modulating the transient receptor potential melastatin type 8 (TRPM8) channel. They discovered an activator (compound 21) and an inhibitor (compound 12), offering new therapeutic strategies for TRPM8-related conditions.
Area of Science:
- Pharmacology
- Neuroscience
- Molecular Biology
Background:
- The transient receptor potential melastatin type 8 (TRPM8) channel is a target for pain and disease treatment.
- Understanding TRPM8 modulation is crucial for developing novel therapeutics.
Purpose of the Study:
- To investigate the structural requirements for TRPM8 channel modulation.
- To identify novel TRPM8 activators and inhibitors using N-substituted tryptamines.
Main Methods:
- Synthesis of N-substituted tryptamines.
- Fluorescence-based screening assay to identify modulators.
- Patch-clamp electrophysiology to characterize compound activity.
- Molecular modeling studies to predict binding sites and modes.
Main Results:
- Compound 21 (2-(1H-indol-3-yl)-N-(4-phenoxybenzyl)ethanamine) acts as a TRPM8 activator with high potency.
- Compound 12 (N,N-dibenzyl-2-(1H-indol-3-yl)ethanamine) functions as a TRPM8 inhibitor.
- Molecular modeling revealed distinct binding modes for the agonist and antagonist within the TRPM8 channel.
Conclusions:
- N-substituted tryptamines represent a promising class of TRPM8 modulators.
- The identified compounds provide valuable tools for studying TRPM8 channel function.
- This research offers potential new avenues for treating pain and other diseases by targeting TRPM8.

01:30Ligand-Gated Ion Channel Receptor: Gating Mechanism
4.7K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

809
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

01:43Thermosensation
35.1K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...

59.4K
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.
