IC50: 3.1 nM (NAMPT), 0.84 μM (CSF1R)

To assess its selectivity, specificity, and effects on cellular NAD levels, LSN3154567 is characterized in various biochemical and cellular assays. LSN3154567 inhibits purified NAMPT with an IC50 of 3.1 nM. When tested against a panel of human kinases (>100; CEREP Kinase panel), it does not exhibit any significant activity (i.e.: IC50≥1 μM) against the kinases tested except CSF1R (IC50≈0.84 μM). LSN3154567 exhibits a broad spectrum of anticancer activity. To assess its anticancer activity, LSN3154567 is tested against a number of different types of cancer cell lines cultured in the absence or presence of nicotinic acid (NA) (10 μM). LSN3154567 exhibits a potent antiproliferative activity against many cell lines in the absence of NA. has not independently confirmed the accuracy of thes

Nampt-IN-1 (LSN3154567) exhibits good physical chemical properties that allow oral dosing. When dosed orally with 2 mg/kg in mice, it has an exposure of 195 nM*hour in the plasma with a peak concentration of 57 nM (at 0.25 hour) and an oral bioavailability of 39%. When dosed intravenously with 2 mg/kg, it has a hepatic clearance of 158.73 mL/min/kg and a volume of distribution at 7.1 L/kg. The half-life of terminal elimination is estimated to be 2.76 hours. LSN3154567 exhibits a dose-dependent inhibition of NAD formation with estimated TED 50 value of 2.0 mg/kg. To assess whether LSN3154567 causes retinopathy, rats are treated with LSN3154567 at 20, 40, and 80 mg/kg for 4 days. No apparent retinopathy is observed. The hematological toxicities are observed. When LSN3154567 is dosed at 20, 40, and 80 mg/kg, the plasma exposures obtained are 8,974, 18,061, and 38,327 M*
