SMI-10B13 is an inhibitor of oncostatin M (OSM) with a dissociation constant (KD) of 6.6 μM. It effectively inhibits OSM-mediated STAT3 phosphorylation in T47D and MCF-7 cell lines, with IC50 values of 136 nM and 164 nM, respectively. SMI-10B13 demonstrates antitumor activity in a human breast cancer mouse model.

| Description | SMI-10B13 is an inhibitor of oncostatin M (OSM) with a dissociation constant (KD) of 6.6 μM. It effectively inhibits OSM-mediated STAT3 phosphorylation in T47D and MCF-7 cell lines, with IC50 values of 136 nM and 164 nM, respectively. SMI-10B13 demonstrates antitumor activity in a human breast cancer mouse model. |
| In vitro | SMI-10B13 (100 μM) almost entirely inhibits the binding ability of gp130 to immobilized OSM. Additionally, SMI-10B13 (10 μM, 30 mins) reduces OSM-mediated pSTAT3 levels in T47D breast cancer cells. |
| In vivo | Twelve hours prior to tumor cell injection, SMI-10B13 (50 mg/kg, administered via intraperitoneal injection) inhibits tumor growth and prolongs survival in a human breast cancer xenograft mouse model. |
