The transient receptor potential (TRP) plays many physiological and pathological roles
in response to extracellular and intracellular stimulation. In this family, there is a group
that responds to temperature changes, the thermoTRP group, where the TRPM8 channel
is located, which is the subject of this study. The TRPM8 channel is a non-selective
cationic polymodal calcium-permeable channel, proposed as the main receptor of
harmless cold, sensitive to soft temperatures and to natural and synthetic cooling
compounds. It is expressed in several tissues of the human body and is involved in a wide
variety of physiological processes and, therefore, an alteration of its expression or
dysfunction causes multiple diseases. Specific modulators of this channel remain a
clinical necessity today, therefore, the global aim of this work was to characterise TRPM8
modulators by screening, potency, cytotoxicity and specificity assays in vitro models. A
family of 8 compounds was used, all of them showed antagonistic activity against
TRPM8, with potency in the micromolar range. The compound 1 being the most potent
of all with an IC50 of 0.07 ± 0.03 μM and the one with the lowest toxicity, thus being the
compound with the best pharmacological profile. In addition, these compounds also
modulate TRPV1 channels. Finally, full characterisation by electrophysiology of the
antagonists with the best properties will allow further development in future preclinical
and clinical trials.
