L-690330 hydrate is a competitive inhibitor of inositol monophosphatase (IMPase) with Kis of 0.27 and 0.19 μM for recombinant human and bovine IMPase, 0.30 and 0.42 μM for human and bovine frontal cortex IMPase, respectively. L-690330 hydrate exhibits 10-fold more sensitive than mouse and rat IMPase[1].
L-690330 hydrate (50 μM; 1 hour) induces P-AMPK and autophagy and increases LC3-I/II and p-AMPK expression in HEK293 cells[2].
L-690330 hydrate (intracerebroventricular injection; 0.1 μmol) has no effects on their motor activity and coordination in the beam walking, except a reduction in time spent in light in the dark/light test[3]. Animal Model: Eight-week-old male ICR mice[3]
