Biological Activity

[Description]:

7ACC1(DEAC; Coumarin D 1421; D 1421) selectively interfere with lactate fluxes in the lactate-rich tumor microenvironment; inhibits lactate influx but not efflux in tumor cells expressing MCT1 and MCT4 transporters.IC50 value: 0.86 uM(Lactate uptake inhibition) [1]Target: MCT inhibitor; lactate transport inhibitorContrary to the reference MCT1 inhibitor AR-C155858, 7ACC unexpectedly inhibited lactate influx but not efflux in tumor cells expressing MCT1 and MCT4 transporters. 7ACC delayed the growth of cervix SiHa tumors, colorectal HCT116 tumors, and orthoptopic MCF-7 breast tumors. MCT target engagement was confirmed by the lack of activity of 7ACC on bladder UM-UC-3 carcinoma that does not express functional MCT. 7ACC also inhibited SiHa tumor relapse after treatment with cisplatin. Finally, we found that contrary to AR-C155858, 7ACC did not prevent the cell entry of the substrate-mimetic drug 3-bromopyruvate (3BP) through MCT1, and contributed to the inhibition of tumor relapse after 3BP treatment.
