CH091138

CH091138 is a potent and selective KRASG12D PROTAC degrader, exhibiting a DC50 value of 148.3 nM in HeLa cells and 469.8 nM in AsPC-1 cells. It selectively targets both exogenous and endogenous KRASG12D through the VHL-mediated ubiquitin-proteasome system, without affecting KRASWT or other KRAS mutants (G12C/G12S/G12V) . CH091138 demonstrates significant antitumor activity by inducing apoptosis (apoptosis) in tumor cells and is applicable for research in pancreatic and colon cancers.
