UR778Br is a small-molecule inhibitor targeting the GTPase-activating protein–related (GRD) domain of IQGAP1, with demonstrated anti-leukemia activity in both in vitro and in vivo preclinical models. In human AML cell lines (e.g., MOLM13, MV4-11, THP-1, U937) and primary AML blasts, UR778Br shows dose-dependent suppression of proliferation (effective low-µM range), induces G2/M cell-cycle arrest, and triggers apoptosis.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
