LC-MB12

Research use only, not for human use.

LC-MB12 is an orally active, selective and potent PROTAC FGFR2 complex that degrades FGFR2.LC-MB12 has antiproliferative and antitumor activity.

LC-MB12 is an orally active PROTAC compound targets FGFR2degradation with a DC50 of 11.8 nM. LC-MB12 contains BGJ398 (a FGFR2 inhibitor), PROTAC linker and CRBN.LC-MB12 inhibits FGFR2 signaling in gastric cancer cells and has anti-tumor activity.

Cell Viability Assay Cell Line:KATO III, SNU-16, NCI-H716 Concentration:0.5 nM, 1.5 nM, 4.3 nM, 13 nM, 41 nM, 123 nM, 370 nM, 1111 nM, 3333 nM, 10000 nM Incubation Time:72 h Result:Inhibited cell growth with IC50s value of 29.1 nM (KATO III); 3.7 nM (SNU-16); 3.2 nM (NCI-H716).Cell Cycle Analysis Cell Line:KATO III Concentration:29.1 nM Incubation Time:72 h Result:Induced G0/G1 cycle arrest.ImmunofluorescenceCell Line:KATO IIIConcentration:100 nM Incubation Time:3 h, 6 h Result:Promoted FGFR2 was relocated from the cell membrane to intracellular vesicles after treated for 3 or 6 h. Induced receptor internalization and re-localization to the perinuclear section after 6 h treatment.Western Blot Analysis Cell Line:KATO III, NCI-H1581 Concentration: 0.5 nM, 1.5 nM, 4.3 nM, 13 nM, 41 nM, 123 nM, 370 nM, 1111 nM, 3333 nM, 10000 nM Incubation Time:6 h Result:Degraded FGFR2 with a DC50 of 11.8 nM and D max of ~80% after 6 h of treatment.Showed time-dependent effect on degradation,with a detectable reduction in FGFR2 levels after 3 h of treatment and ~90% degradation after 12 h.Degraded of FGFR2 in KATO by 77%, and in NCI-H1581 by 43% after 100 nM treatment for 6 h.

Animal Model:SNU-16 xenografted in BALB/c-nu mice.Dosage:20 mg/kg/day Administration:oral administration (p.o.) 15 days Result:Achieved 63.1% tumor growth inhibition innocuously. Inhibited FGFR phosphorylation and total FGFR2 protein and decreased phosphorylation levels of downstream pPLCγ and ERK1/2.
