Biological Activity
TUG-770 is a highly potent free fatty acid receptor 1 (FFA1/GPR40) agonist with EC50 of 6 nM for hFFA1.
In Vitro
TUG-770 (Compound 22) displayed excellent physicochemical and in vitro ADME properties, with good aqueous solubility, good chemical stability, low lipophilicity, and decreased plasma protein binding (PPB). TUG-770 furthermore showed excellent stability toward human liver microsomes (HLM), no inhibition of selected CYP-enzymes implicated in drug-drug interactions, no P-glycoprotein (P-gp) inhibition, and good permeability in the Caco-2 cell assay [1].
In Vivo
Examination of TUG-770 in an acute intraperitoneal glucose tolerance test (IPGTT) in normal mice revealed a good dose dependent response with maximal reduction in glucose level reached at 50 mg/kg. The effect of TUG-770 was fully sustained after 29 days of daily oral treatment. Additional evaluation of TUG-770 in rats confirmed a significant glucose lowering effect for the high doses already after 10 min and for all doses after 30 min [1].
