URML-3881 (URML3881) is a potent, specific MEK1/2 inhibitor IC50 of 30 nM in a cell-free kinase inhibition assay.URML-3881 shows no inhibition among a panel of other kinases including MEK 3 and MEK5, which are activated in alternative MAPK signaling pathways.URML-3881 reduces MAPK pathway activity in clear cell ovarian cancer (CCOC).URML-3881 causes reduced CCOC viability due to induction of tumor cell apoptosis and inhibition of proliferation.URML-3881 abrogates cisplatin-induced prosurvival MAPK signaling in CCOC, resulting in durable and dramatic tumor regression in vivo.

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.
