YX-2-107 — Datasheet

Biological Activity

YX-2-107 is a CRBN-recruiting and specific CDK6-degrading PROTAC with IC50 of 0.69 and 4.4 nM for CDK4 and CDK6 in vitro, selectively degardes CDK6 in Ph+ BV173 ALL cells with a degradation constant of 4 nM. YX-2-107 does not affect expression of IKZF1 and IKZF3, and does not degarde CDK4 protein. YX-2-107 inhibits S-phase entry, cell proliferation, RB phosphorylation, and FOXM1 expression and induces the selective degradation of CDK6 in Ph+ BV173 and SUP-B15 cells.| PROTAC YX-2-107 is bioavailable in mice and pharmacologically active in suppressing Ph+ ALL proliferation in a mouse xenograft of Ph+ ALL, comparable or superior to that of the CDK4/6 enzymatic inhibitor palbociclib.
