Research use only, not for human use.

MK-8353 (SCH-900353) is a?highly potent, orally bioavailable, dual-specificity ERK1/2 inhibitor with IC50 of 23.0/8.8 nM, respectively.

MK-8353 (SCH-900353) is a?highly potent, orally bioavailable, dual-specificity ERK1/2 inhibitor with IC50 of 23.0/8.8 nM, respectively; inhibits nonactivated ERK2 with IC50 of 0.5 nM, demonstrates excellent kinase selectivity over a 227-human kinase panel; decreases pERK1, pERK2, and ribosomal S6 kinase (pRSK) proteins, with complete suppression of pERK1 and pERK2 observed at 30 nM in A2058 cells, inhibits the in vitro proliferation of a panel of BRAFV600-mutant and RAS-mutant cancer cell lines; exhibits in vivo antitumor activity against BRAFV600 mutant Colo-205 colon cancer model and the BRAFV600 mutant SK-MEL-28 melanoma model.

MK-8353 is a potent, selective and orally available ERK1/2 inhibitor, with IC50s of 23.0 nM and 8.8 nM, respectively; MK-8353 has antitumor activity. MK-8353 only at 1 μM shows >50% inhibition on 3 kinases (CLK2, FLT4, and Aurora B), and no other kinases tested are inhibited by >35% at 0.1 μM. MK-8353 also shows potent antitumor activity against various cancer cell lines, such Malme-3M cells (Melanoma), Colo-205 cells (Colon), NCI-H292 cells (Lung), A-549 cells (NSCLC), 8505C cells (Thyroid), SW-626 cells (Ovarian), with EC50s of 21 nM, 19 nM, 130 nM, 230 nM, 210 nM, 108 nM.

MK-8353 (60 mg/kg, p.o., bid (twice daily)) causes at least 50% tumor growth inhibition or regression in 83% of the animal models bearing different tumor cells, including LOX, Colo-205, MIA PaCa-2, and Calu-6 cells.
