| Description | MSC-4381 (MCT4-IN-1) is an orally available and selectively modeled highly potent inhibitor of monocarboxylic acid transporter protein 4 (MCT4/SLC16A3) with potential anticancer and antitumor activity for the study of osteosarcoma. |
| In vitro | MCT4-IN-1 (compound 18n) inhibits lactate efflux in the MDA-MB-231 cell line with an IC50 of 1 nM. On-target activity was confirmed by fluorescence cross correlation spectroscopy (FCCS)[1] with a Ki of 11 nM[1]. |
| In vivo | When MCT4-IN-1 (30 mg/kg; oral; single dose) was used only in combination with MCT1/2 inhibitors, lactic acid accumulation in tumor cells was significant; MCT4-IN-1 (30 mg/kg/day; for 15 consecutive days) had no significant antitumor activity; MCT4-IN-1 (0.2 mg/kg; intravenous injection) had a T1/2 of 1 hour, a CL of 0.33 L/hkg, a Cmax of 489 ng/mL, and a Vss of 0.4 L/kg in mice[1]. |
