LPM4870108 (compound 10) inhibits the activities of TrkA, TrkB, and TRC with high selectivity at 0.5 μM (kinase activity remaining, <10%) and slightly inhibit the activities of ALK and ROS1 (kinase activity remaining, 10-30%)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
LPM4870108 (2 mg/kg; a single i.v.) exhibits terminal half-life (t1/2) (male 0.87 h, 2.21 h), the Cl (male 19.3 mL/kg/min, female 8.19 mL/kg/min), and the AUC0-t (male 4191 nM•h, female 10282 nM•h) in rats[1].
LPM4870108 (10 mg/kg; a single p.o.) exhibits oral bioavailability (male 56.0%, female 61.9%), Cmax (male 6384 nM, female 6628 nM) and Tmax (male 0.667 h, female 0.667 h) in rats[1].
