sinapoyltyramine
C19H21NO5 (343.14196560000005)
Sinapoyltyramine belongs to hydroxycinnamic acids and derivatives class of compounds. Those are compounds containing an cinnamic acid (or a derivative thereof) where the benzene ring is hydroxylated. Sinapoyltyramine is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Sinapoyltyramine can be found in a number of food items such as komatsuna, common mushroom, pomes, and chickpea, which makes sinapoyltyramine a potential biomarker for the consumption of these food products.

A-841720
C17H21N5OS (343.14667360000004)
A-841720 is a potent, non-competitive and selective mGlu1 receptor antagonist with an IC50 of 10 nM for human mGlu1 receptor. A-841720 displays 34-fold selectivity over mGlu5 (IC50 of 342 nM), and no significant activity at a range of other neurotransmitter receptors, ion channels, and transporters. A-841720 has the potential for chronic pain research[1][2].
