SCIO-469

Research use only, not for human use.

A potent, selective p38α MAPK inhibitor with IC50 of 9 nM.

A potent, selective p38α MAPK inhibitor with IC50 of 9 nM; displays 10-fold selectivity for p38α over p38β, >2,000-fold selectivity over a panel of 20 other kinases, including other MAP kinases; decreases apoptosis in MDS CD34+ progenitors and leads to dose-dependant increases in erythroid and myeloid colony formation; enhances the ability of MG132 and bortezomib to induce the apoptosis of MM cells, and inhibits tumor growth in vivo.Rheumatoid Arthritis Phase 2 Discontinued.

Talmapimod (SCIO-469) (100-200 nM; 1 hour) inhibits phosphorylation of p38 MAPK in MM cells.Talmapimod inhibits LPS-induced TNF-a production in human whole blood.Talmapimod decreases constitutive p38alpha MAPK phosphorylation of both 5T2MM and 5T33MM cells.Western Blot Analysis Cell Line:MM.1S, U266, RPMI8226, MM.1R, and RPMI-Dox40 cell lines Concentration:100, 200 nM Incubation Time:1 hour Result:Strongly inhibits phosphorylation of p38 MAPK.

Targeting p38α MAPK with Talmapimod (SCIO-469) decreases myeloma burden in addition to preventing the development of myeloma bone disease.Talmapimod inhibits multiple myeloma growth and prevents bone disease in the 5T2MM and 5T33MM models.Talmapimod (10-90 mg/kg; p.o.; twice daily orally for 14 days) dose-dependently reduced tumor growth and also dose-dependently reduced weight of the palpable tumors at termination. Animal Model:Six-week-old male triple immune-deficient BNX mice (RPMI-8226 MM palpable tumors)Dosage:P.o.; twice daily orally for 14 days Administration:10, 30, 90 mg/kg Result:Dose-dependently reduced tumor growth.
