Uses
Lycoperodine-1 (Cyclomethyltryptophan) is an active product that can be isolated from tomato fruits (Lycopersicon sculentum). Lycoperodine-1 act as an agonist of Ca2+ sensing receptors (CaSR)[1].
Biochem/physiol Actions
TNCA is a tryptophan derivative that binds the parathyroid Ca2+-sensing receptor (CaSR) extracellular domain (ECD) hinge region between two globular subdomains and acts as a high-affinity CaSR ligand (CaSRL) with co-agonist activity. TNCA is shown to potentiate both Mg++- and Ca++-evoked cellular calcium response (0.1-0.5 mM), as well as Mg++-evoked cellular ERK1/2 phosphorylation in CaSR-expressing HEK293 cells (0.5 mM). AC-265347 (Cat. No. SML0129), on the other hand, is a calcimimetic that functions as a CaSR agonist.
