MS910
MS910 is a CRBN-recruiting MEK1/2 PROTAC degrader, with a DC50 of 94 nM against MEK1 and 38 nM against MEK2 in SK-MEL-28 cells. MS910 induces the degradation of GSPT1, IKZF1/3 and ZFP91, thereby inhibiting the downstream ERK signaling pathway and cancer cell growth. MS910 is applicable to research related to colorectal cancer and melanoma.

MS910 (compound 50) (3 days) inhibits the proliferation of SK-MEL-28 melanoma cells, with a GI50 of 780 nM[1].
MS910 (3 days) potently inhibits the proliferation of HT-29 colorectal cancer cells, with a GI50 of 0.3 μM[1].
MS910 (0-10 μM; 24 h) potently and selectively degrades MEK1 (DC50 = 118 nM) and MEK2 (DC50 = 55 nM) in HT-29 cells, while inhibiting the phosphorylation of downstream MEK and ERK[1].
MS910 (0-10 μM; 24 h) efficiently and selectively degrades MEK1 (DC50 = 94 nM) and MEK2 (DC50 = 38 nM) in SK-MEL-28 cells, while inhibiting the phosphorylation of downstream MEK and ERK[1].
MS910 (0.3 μM; 2-24 h) induces time-dependent degradation of MEK1 and MEK2 in HT-29 cells, with significant degradation observed at 4 h, maximal degradation achieved at 8-10 h, followed by inhibition of ERK phosphorylation[1].
MS910 (0.3 μM; 8 h) induces the degradation of MEK1/2 in HT-29 cells via the ubiquitin-proteasome system in a CRBN-dependent manner, a process that requires binding to MEK1/2[1].
MS910 (0-300 nM; 10 days) effectively inhibits colony formation of HT-29 colorectal cancer cells, and exhibits stronger activity than its non-degradative control[1].
Treatment of HT-29 and SK-MEL-28 cells with MS910 (0.1 nM-10 μM) for 24 h induces concentration-dependent degradation of MEK1 and MEK2 proteins[1].
MS910 (1 nM-100 μM) binds to MEK1 and MEK2 proteins in a concentration-dependent manner[1].
Treatment of HT-29 cells with MS910 (0.3 μM; 8 h) reduces the protein levels of MEK1 and MEK2[1].
MS910 (0.0001-10 μM; 24 h) induces concentration-dependent degradation of MEK1, MEK2, GSPT1, IKZF1 and IKZF3, but does not induce ZFP91 degradation, following 24-hour treatment of HT-29 cells[1].
MS910 (0.3 μM; 8 h) exhibits high selectivity for MEK1 and MEK2 in HT-29 cells[1].
MS910 (0.0001-10 μM; 24 h) does not degrade most CRBN neo-substrates (GSPT1, IKZF1, ZFP91) in HT-29 cells, but degrades IKZF3 at concentrations above 1 μM, and exhibits higher potency in degrading MEK1/2 than IKZF3[1].
