MS1129
MS1129 is a DNMT degrader that induces proteasomal degradation of DNMT1, DNMT3A and DNMT3B proteins. MS1129 upregulates TRAIL, DR4 and DR5 proteins, downregulates the decoy receptor DcR2, and activates TRAIL-dependent apoptosis via the HIF-1/2 and Caspase-10 pathways. MS1129 is applicable to the research of VHL-deficient clear cell renal cell carcinoma.

MS1129 (2 μM; 3 days) induces robust apoptosis in parental VHL-deficient RCC10 clear cell renal cell carcinoma cells, and this effect is dependent on the expression of HIF-1α/2α[1].
MS1129 inhibits the viability of parental VHL-deficient RCC10 clear cell renal cell carcinoma (ccRCC) cells with an IC50 of 1.3 μM, while its potency decreases in HIF-1α/2α double knockout (DKO) RCC10 cells (IC50 = 3.2 μM)[1].
MS1129 (2 μM; 0-48 h) induces time-dependent proteasomal degradation of DNMT1, DNMT3A and DNMT3B proteins in RCC10 clear cell renal cell carcinoma cells, with the maximum degradation level reached at 48 h[1].
MS1129 (1-3 μM; 2 days) induces apoptosis in RCC10 clear cell renal cell carcinoma (ccRCC) cells by activating caspase-3, caspase-7 and PARP1, while the pan-caspase inhibitor Z-VAD-FMK (HY-16658B) partially inhibits this effect[1].
MS1129 (2 μM; 2 days) activates the TRAIL death receptor signaling pathway in RCC10 ccRCC cells by upregulating TRAIL, DR4 and DR5, downregulating DcR2, and inducing caspase-10 cleavage[1].
