CAS No.: 2229974-73-4

Cyclin D1 degrader MS28 (XY028-133)

货号: PC-26498Not For Human Use, Lab Use Only.

Cyclin D1 degrader MS28 (XY028-133) is a potent, selective and first-in-class PROTAC degrader of cyclin D1 through recruiting the CDK4/6-cyclin D1 complex to VHL E3 ligase, effectively degrades cyclin D1 in Calu-1 cells with DC50 of 950 nM and Dmax of 90% (8 h).

生物&药学活性

Cyclin D1 degrader MS28 (XY028-133) is a potent, selective and first-in-class PROTAC degrader of cyclin D1 through recruiting the CDK4/6-cyclin D1 complex to VHL E3 ligase, effectively degrades cyclin D1 in Calu-1 cells with DC50 of 950 nM and Dmax of 90% (8 h).
MS28 displays modest degradation effects on CDK4/6 with DC50 > 10 μM and Dmax < 50% at the 8 h time point。
MS28 at 0.3 μM reduces the CDK6 protein level close to 50%, while it has no effect on CDK4.
MS28 preferentially degrades Cyclin D1 over CDK4/6.
MS28 degrades cyclin D1 by recruiting the CDK6-cyclin D1 complex to VHL, degrades cyclin D1 in a VHL-, CDK6- and UPS-dependent manner.
MS28 does not degrade cyclin D2 or other major cyclins and CDKs, such as cyclin B1 and CDK2.
MS28 effectively suppressed the proliferation of Calu-1 cells with GI50 of 1.0 uM, significantly reduced the mRNA levels of E2F target genes at 8 h of treatment in Calu-1 cells.
MS28 phenocopied the effect of CCND1 KO in Calu-1 cells, inhibited the clonogenicity of Calu-1 cells.
