SERP Comments:

Cytotoxicity was observed at 17 nM and 45 nM at different timepoints. Cell EC50s for TRPC4 and TRPC5 are 11 nM and 8 nM, respectively; therefore, there is an insufficient window between on-target activity and cytotoxicity to interpret cellular effects of the compound as target-based.

SERP Comments:

There have been several papers showing that this compound activates TRPC4/5 including doi: 10.1002/anie.201411511. The data in those papers is quite convincing that the compound at low nM concentrations activates these channels and that it may mediate some of its anti-tumor activity via this effect. However, there is no convincing dataset regarding potential off-targets, as it has not yet been broadly screened against kinases, GPCRs, ion channels, and so on. Thus, provided the user does the appropriate controls (e.g., TRPC4/5 KO cells as a control), the compound will likely be useful.
