PLX647 dihydrochloride 

Cat. No.: HY-13838A
Handling Instructions

PLX647 dihydrochloride is an orally active, highly specific dual FMS and KIT kinase inhibitor, with IC50s of 28 and 16 nM, reapectively. PLX647 dihydrochloride shows selectivity for FMS and KIT over a panel of 400 kinases at a concentration of 1 μM except FLT3 and KDR (IC50s=91 and 130 nM, respectively).

Description

PLX647 dihydrochloride is an orally active, highly specific dual FMS and KIT kinase inhibitor, with IC50s of 28 and 16 nM, reapectively. PLX647 dihydrochloride shows selectivity for FMS and KIT over a panel of 400 kinases at a concentration of 1 μM except FLT3 and KDR (IC50s=91 and 130 nM, respectively)[1].

In Vitro

In vitro, PLX647 dihydrochloride potently inhibits proliferation of BCR-FMS cells, with an IC50 of 92 nM. A corresponding Ba/F3 cell line expressing BCR-KIT is also quite sensitive to PLX647 dihydrochloride, with an IC50 of 180 nM. PLX647 dihydrochloride also inhibits endogenous FMS and KIT, as demonstrated by inhibition of the ligand-dependent cell lines M-NFS-60 (IC50=380 nM) and M-07e (IC50=230 nM), which express FMS and KIT, respectively[1].
PLX647 dihydrochloride potently inhibits the growth of FLT3-ITD-expressing MV4-11 cells (IC50=110 nM). PLX647 dihydrochloride displays minimal inhibition of the proliferation of Ba/F3 cells expressing BCR-KDR (IC50=5 μM). PLX647 dihydrochloride inhibits osteoclast differentiation with an IC50 of 0.17 μM[1].

In Vivo

PLX647 dihydrochloride (40 mg/kg; p.o.; twice daily for 7 days) reduces macrophage accumulation in UUO kidney and blood monocytes[1].
PLX647 dihydrochloride (40 mg/kg; p.o.; male Swiss Webster mice) reduces LPS-induced TNF-α and IL-6 release[1].
PLX647 dihydrochloride (20-80 mg/kg; p.o.; daily or twice daily from 27-41 days) shows effects on collagen-induced arthritis[1].
PLX647 dihydrochloride (30 mg/kg) results in significant inhibition of TRAP5b immunostaining and bone osteolysis. PLX647 dihydrochloride (30 mg/kg BID) is able to prevent bone damage by the tumor cells[1].

Animal Model: Male C57BL/6 mice (mouse unilateral ureter obstruction model)[1]
Dosage: 40 mg/kg
Administration: P.o.; twice daily for 7 days
Result: Resulted in reduction in the levels of F4/80+ macrophages by 77%.
Animal Model: 7-9 wk old Male DBA/1J mice (Mouse collagen-induced arthritis model)[1]
Dosage: 20 mg/kg, 80 mg/kg
Administration: P.o.; daily (20 mg/kg) from 27-41 days, twice daily (80 mg/kg) from 27-41 days
Result: 20 mg/kg PLX647 had no initial effect on the development of severe arthritis. However, starting on day 33, no further development of disease severity was recorded, and a 30% inhibition of the macroscopic signs of arthritis was evident in clinical score on day 41. Mice treated with 80 mg/kg BID PLX647 initially shows delayed development of severe arthritic signs. Starting on day 33, the signs of arthritis began to decrease in this treatment group, reaching a maximum reversal of 76% on day 41.
