AZD8330 is an orally active and selective MEK1/2 inhibitor with an IC50 of 7 nM. The inhibition of MEK1/2 by this component results in inhibition of growth factor-mediated cell signaling and tumor cell proliferation.

MEK, also known as MAP kinase kinase (MAP2K), is a kinase enzyme which phosphorylates mitogen-activated protein kinase (MAPK). The activation of MAPK signaling pathway was shown to be involved in regulation of various cell processes including cell proliferation, differentiation, apoptosis, metabolism and inflammation.

AZD8330 treatment was shown to cause cell apoptosis by suppressing the activation of ERK1/2 signal transduction pathway in Burkitt's lymphoma cell line Raji cells, which is in a dose and time dependent manner [1].

Recently, a large phase I trial of 82 patients with advanced tumor malignancies was conducted to define the maximum tolerated dose (MTD) and assessed the safety, tolerability, pharmacokinetics and pharmacodynamics of AZD8330. The MTD of this product was determined as 40mg/day [2].

Cell experiment [1]:

Cell lines

MOS, U2OS, KPD, ZK58, 143b and Saos-2 cells

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months.

Reacting condition

0 ~ 1 μM; 72 hrs


AZD8330 decreased viability of MOS and U2OS cells, and significantly affected 143b cells. In contrast, AZD8330 exhibited no effect on viability of KPD, ZK58 and Saos-2 cells. According to a capase3/7 activity assay, AZD8330 at the concentration of 0.5μM induced apoptosis in MOS and U2OS cells, but not in KPD and ZK58 cells.
