| Uses | Dofequidar (MS-209) sesquifumarate is an orally active quinoline compoundthat blocks P-glycoprotein (P-gp) and multidrug resistance-associated protein-1 (MDR-1). Dofequidar sesquifumarate has highly potent reversing effect on multidrug-resistant tumor cells. Dofequidar sesquifumarate competitively inhibits ABCB1/P-gp, ABCC1/MRP-1, blocks the efflux of chemotherapeutic agents, increases the drug concentration in cancer cells, and enhances the chemotherapeutic effect[1][2]. | | in vivo | Dofequidar (200 mg/kg; orally administered; starting from days 10 or 14 after tumor cell inoculation, 4 doses) sesquifumarate in NK cell-depleted SCID mice inoculated with SBC-3/ADM or SBC-3 cells significantly inhibits the metastasis of SBC-3/ADM cells to multiple organs when combined with Etoposide (VP-16) (HY-13629) or Adriamycin[1].
Dofequidar (200 mg/kg; orally administered; given 30 minutes before Irinotecan (CPT-11) (HY-16562) injection, and both are administered on days 0, 4, and 8; throughout the experiment) sesquifumarate in nude mice inoculated with HeLa SP cells significantly reduces the tumor volume when combined with Irinotecan[2]. | Animal Model: | 6- to 8-week-old male severe combined immunodeficiency (SCID) mice, depleted of natural killer (NK) cells by intraperitoneal injection of TM-β1 Ab (1 mg/mouse) 2 days before tumor inoculation, and then inoculated intravenously with SBC-3 or SBC-3/ADM cells[1] | | Dosage: | 200 mg/kg | | Administration: | Orally administered; the mice inoculated with SBC-3 cells were treated on days 14, 15, 21, and 22; the mice inoculated with SBC-3/ADM cells were treated on days 10, 11, 17, and 18. | | Result: | Combined use with Etoposide (VP-16) (HY-13629) or Adriamycin can significantly inhibit metastasis formation by SBC-3/ADM cells to the liver, kidneys, and lymph nodes, and the weight of the liver of the treated mice was significantly less than that of other groups. |
| Animal Model: | 5- to 6-week-old female BALB/c-nu/nu (nude) mice, inoculated subcutaneously with HeLa SP cells[2] | | Dosage: | 200 mg/kg | | Administration: | Orally administered 30 minutes before intravenous injection of Irinotecan (67 mg/kg); on days 0, 4, and 8. | | Result: | Co-treatment with Irinotecan drastically decreased the tumor volume. |
