EZM 2302 Biological Activity
| Description | EZM 2302 is an inhibitor of coactivator-associated arginine methyltransferase 1 (CARM1) with an IC50 of 6 nM. |

| Target | IC50: 6 nM (CARM1)[1] |

| In Vitro | EZM 2302 binds to CARM1 and is a selective inhibitor of CARM1 activity (IC50=6 nM) with broad selectivity against other histone methyltransferases. Treatment of MM cell lines with EZM 2302 leads to inhibition of PABP1 and SMB methylation and cell stasis with IC50 values in the nanomolar range (9, 31 nM, respectively). EZM 2302 inhibits the in vitro proliferation of multiple hematopoietic cell lines, with day 14 IC50 values of less than 100 nM in 9 of 15 cell lines[1]. |
|---|
| In Vivo | EZM 2302 is stable in human hepatocytes (CL<3 mL/min/kg), and moderately binds to human, mouse and rat plasma proteins with a mean fraction unbound of 0.66, 0.46 and 0.74, respectively. In mouse and rat, the plasma clearance (CL) is 43 and 91 mL/min/kg, respectively. EZM 2302 shows dose-dependent exposure and tumor growth inhibition (TGI) after 21 days in the RPMI-8226 xenograft model. Tumors in all EZM 2302 dose groups measured on day 21 show significant decreases in tumor growth compared to vehicle[1]. |
|---|
| Cell Assay | Cultured cells in linear/log phase growth are split to a seeding density of 2e5 cells/mL in 2–20mLs of media, depending on the yield required at the end of the growth period. EZM 2302 is diluted in DMSO and added to each culture vessel with a final DMSO concentration of 0.2%. Cells are allowed to grow for 96 hours. At the conclusion of each treatment period, cells are harvested by centrifugation (5 minutes, 1200 rpm), and cell pellets are rinsed once with PBS before being frozen on dry ice pending further processing[1]. |
|---|
| Animal Admin | Rats[1] Male Sprague-Dawley rats (n=3) are treated with a single dose of EZM2302 at 2 mg/kg by intravenous (i.v.) injection and 10 mg/kg by oral gavage administration (p.o.; mouse only), formulated in 5% dextrose in water, pH 3.5. An additional group of rats, cannulated in both the jugular and portal veins are dosed by oral gavage (10 mg/kg, in 0.5% methylcellulose in water). Approximately 110 μL of blood is taken from the animals by retro-orbital bleeding (mouse), tail vein (rat i.v.) or both jugular and portal vein sampling (rat p.o.) at pre-specified time intervals. The 2 h samples are split for parallel determination of blood and plasma concentration[1]. Mice[1] RPMI-8226 cells are inoculated at 5×106 cells/mouse and treatment began when the mean tumor sizes reach 120 mm3 (28 days post-inoculation). CB-17 SCID Mice are assigned into groups using a randomized block design. EZM2302 or vehicle (0.5% methylcellulose in water) is administered orally BID at a dose volume of 37.5, 75, 150, or 300 mg/kg for 21 days. Body weights are measured twice a week for the duration of the study. Tumor size is measured twice weekly in two dimensions using a caliper, and the volume is expressed in cubic millimeters. Animals are euthanized 3 hours post-final dose, with blood and tissues collected for analysis[1]. |
