|S1130||YM155 (Sepantronium Bromide)||89 mg/mL||55 mg/mL||6 mg/mL|
YM155 (Sepantronium Bromide) is a potent survivin suppressant by inhibiting Survivin promoter activity with IC50 of 0.54 nM in HeLa-SURP-luc and CHO-SV40-luc cells; does not significantly inhibit SV40 promoter activity, but is observed to slightly inhibit the interaction of Survivin with XIAP. Phase 2.
MM cell lines UM9 (left panel) or U266 (right panel) were cultured in presence or absence of accessory cells prior to incubation with CTLs alone, YM155 alone or the combination. Survival of UM9 and U266 MM cells was assessed by CS-BLI. Results show % lysis of MM cells after 24 hour incubation and are depicted for three doses.
