Description: Ulixertinib, also known as BVD-523 and VRT752271, is an inhibitors of ERK protein kinase. Downmodulation of ERK protein kinase activity inhibits VEGF secretion by human myeloma cells and myeloma-induced angiogenesis. Upon oral administration, BVD-523 inhibits both ERK 1 and 2, thereby preventing the activation of ERK-mediated signal transduction pathways. This results in the inhibition of ERK-dependent tumor cell proliferation and survival. The mitogen-activated protein kinase (MAPK)/ERK pathway is often upregulated in a variety of tumor cell types and plays a key role in tumor cell proliferation, differentiation and survival.

Biological target: Ulixertinib (BVD-523; VRT752271) is an inhibitor of ERK1/2 kinases with an IC50 of <0.3 nM against ERK2.
In vitro activity: Whether ulixertinib could antagonize multidrug resistance (MDR) mediated by ATP-binding cassette (ABC) transporters was investigated. The results showed that ulixertinib, at non-toxic concentrations, significantly reversed ATP-binding cassette subfamily B member 1 (ABCB1)- and ATP-binding cassette subfamily G member 2 (ABCG2)-mediated MDR. In ABCB1-overexpressing cells, ulixertinib antagonized MDR by attenuating the efflux function of ABCB1. Similarly, in ABCG2-overexpressing cells, ulixertinib inhibited the efflux activity of ABCG2 and reversed resistance to substrate anticancer drugs. The reversal effects of ulixertinib were not related to the down-regulation or change of subcellular localization of ABCB1 or ABCG2. Mechanistic investigations revealed that ulixertinib stimulated the ATPase activity of both ABCB1 and ABCG2 in a concentration-dependent manner, and the in silico docking study predicted that ulixertinib could interact with the substrate-binding sites of both ABCB1 and ABCG2.

In vivo activity: In in vivo xenograft studies, BVD-523 showed dose-dependent growth inhibition and tumor regression. BVD-523 yielded synergistic antiproliferative effects in a BRAFV600E-mutant melanoma cell line xenograft model when used in combination with BRAF inhibition. Antitumor activity was also demonstrated in in vitro and in vivo models of acquired resistance to single-agent and combination BRAF/MEK-targeted therapy.
