Biological Activity

Description

TUG-891 is a potent and selective agonist of the long chain free fatty acid (LCFA) receptor 4 (FFA4/GPR120), which demonstrates both potential opportunity and possible challenges to therapeutic agonism.

Targets

FFA4/GPR120 ^[1]

In vitro
In vitro	TUG-891 displays similar signaling properties to the LCFA α-linolenic acid at human FFA4 across various assay end points, including stimulation of Ca_²⁺ mobilization, β-arrestin-1 and β-arrestin-2 recruitment, and extracellular signal-regulated kinase phosphorylation. Activation of human FFA4 by TUG-891 also results in rapid phosphorylation and internalization of the receptor. ^[1]
Cell Research	Cell lines	Human FFA4-eYFP Flp-In T-REx cells, HT-29 cells
	Concentrations	10 μM
	Incubation Time	1.5 min, 5 min, 45 min
	Method	Intracellular Ca₂₊ is monitored for 1.5 min after TUG-891 treatment, and the measured response is taken as the peak signal over this time course. Extracellular signal-regulated kinase 1/2 (ERK) phosphorylation is examined in Flp-In T-REx cell lines, or in HT-29 cells after 5 minutes of TUG-891 treatment. For visualization of FFA4 Internalization, human FFA4-eYFP Flp-In T-REx cells are cultured on poly-d-lysine coated glass coverslips and cultured for 24 hours before treatment with doxycycline (100 ng/ml) to induce receptor expression. Live cells are imaged after TUG-891 addition using a confocal microscopy system.

In Vivo
In vivo	TUG-891 acutely increases fat oxidation and reduces body weight and fat mass in C57Bl/6J mice by activating GPR120.^[2]
