Summary
MSC-4381 (MCT4-IN-1) is an orally active and selective monocarboxylate transporter 4 (MCT4/SLC16A3) inhibitor with an IC 50 of 77 nM and a K i of 11 nM. MSC-4381 targets to the cytosolic domain of MCT4 . MSC-4381 results in lactate efflux inhibition and reduction of cellular viability in MCT4 high expressing cells. MSC-4381 has the potential for MCT4 transporter inhibition research [1] .
IC50 & Target
|
MCT4 77 nM (IC 50 ) |
MCT4 11 nM (Ki) |
In Vitro
MSC-4381 (compound 18n) inhibits lactate efflux in the MDA-MB-231 cell line with an IC
50
of 1 nM. The on-target activity is confirmed with a K
i
of 11 nM by fluorescence cross-correlation spectroscopy (FCCS)
[1]
.
MSC-4381 does not inhibit lactate efflux to a similar extent in SNU-398 and MiaPaca2, and only 600-fold less in RT-4 cell lines
[1]
.
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
MSC-4381 (compound 18n; 30 mg/kg; PO; single dose) only combined with MCT1/2 inhibitor exhibits a significant tumoral intracellular lactate accumulation
[1]
.
MSC-4381 (30 mg/kg/day; for 15 days) shows no significant antitumor activity
[1]
.
MSC-4381 (0.2 mg/kg; iv) has a T
1/2
of 1 hours, a CL of 0.33 L/h•kg, a C
max
of 489 ng/mL and a V
ss
of 0.4 L/kg for mice
