生物活性:
LPM4870108 is a potent and orally active pan-Trk (WT and MT) inhibitor, with IC50s of 0.2 nM, 2.4 nM, 3.5 nM and 2.3 nM for TrkC, TrkA, TrkAG595R and TrkAG667C, respectively. LPM4870108 shows selectivity for Trk over ALK (IC50=182 nM). LPM4870108 exhibits anti-tumor activity.

体内研究:
LPM4870108 (compound 10) (5-20 mg/kg; p.o. once daily for 21 days) inhibits tumor growth in BaF3-NTRK xenograft tumor models.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.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.Animal Model:Mice bearing 100-200 mm3 BaF3-NTRK tumors
