生物活性

Licarin B, a nitric oxide production inhibitor extracted from the component of the seeds of Myristica fragrans, improves insulin sensitivity via PPARγ and activation of GLUT4 in the IRS-1/PI3K/AKT pathway[1][2][3].

IC50 & Target

PPARγ

 

GLUT4

 

体外研究
(In Vitro)

Licarin B (5 μM, 10 μM, 15 μM. 8 days) moderately increases TG accumulation during adipogenic differentiation and showed partial PPARg agonist activity in 3T3-L1 preadipocytes[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[1]

Cell Line: 3T3-L1 cell.
Concentration: 1-500 μM.
Incubation Time: 48 h.
Result: Did not cause significant cell death up to 500 μM concentration.

Cell Viability Assay[1]

Cell Line: 3T3-L1 cell.
Concentration: 5 μM, 10 μM, 15 μM.
Incubation Time: 8 days (replaced every 2 days).
Result: LB at 15 μM concentration significantly promoted adipocyte differentiation and caused intracellular TG accumulation.
