YL246
YL246 is a selective, CRBN-recruiting HDAC8 PROTAC degrader, DC50 = 3.75 nM. YL246 induces CRBN- and proteasome-dependent degradation of zinc-dependent HDAC8 through CRBN ligand-mediated ubiquitination. YL246 has poor metabolic stability. YL246 can be used for HDAC8-mediated cancer-related research, such as breast cancer.

In Vitro
YL246 (compound A10) (1-16000 nM; 8 h) induces >95% HDAC8 degradation at 16 nM, with a DC50 of 3.75 nM in MDA-MB-231 cells, whereas no HDAC1/2/3 degradation is detected at concentrations up to 16 μM[1].
YL246 is metabolically unstable in CD-1 mouse liver microsomes, and its half-life is significantly shorter than that of the shorter ZBG analog[1].
