Biological Activity

In Vitro:

Cell Line
Concentration Treated Time Description References
786-0 human renal adenocarcinoma cells 25 μM IMR-1 treatment decreased the occupancy of Maml1 on the HES1 promoter but did not affect the occupancy of Notch1, indicating that IMR-1 specifically disrupts the recruitment of Maml1 to chromatin. Cancer Res. 2016 Jun 15;76(12):3593-603
OE33 human esophageal adenocarcinoma cells 25 μM IMR-1 treatment decreased the occupancy of Maml1 on the HES1 promoter but did not affect the occupancy of Notch1, indicating that IMR-1 specifically disrupts the recruitment of Maml1 to chromatin. Cancer Res. 2016 Jun 15;76(12):3593-603
RL952 cells 10 mg Inhibited Notch signaling pathway, reduced expression of MSH2 and MSH6 Clinics (Sao Paulo). 2021 Nov 19;76:e3318
