Transient potential receptors (TRPs) are a group of eight ion channel subfamilies based on sequence homology and cation permeability, which play critical roles in the responses of external stimuli. This study is focused on TRPM8, a well-known thermoregulator channel involved in sensory transduction of different stimuli. Several studies have found that the TRPM8 dysregulation is associated with diverse pathologies development. Although all the research advances, TRPM8 specific modulators still are a clinical need. Therefore, the objective of this study was to characterize eight compounds derived from tryptamines, chemically synthesized, as modulators of TRPM8, through screening, potency, cytotoxicity, and specificity tests by in vitro techniques. Compounds with the best pharmacological properties were C5 (IC50= 0.4 ± 1.5 μM) and C8 (IC50 = 0.4 ± 1.1 μM). All tryptamine derivatives tested induced specific antagonism in TRPM8, which highlight the relevance of this configuration in future modulators development. Finally, the complete characterization of best antagonists by electrophysiological characterization it´s the key for further development into preclinical and clinical studies.
