Background:

MS432 is a first-in-class and highly selective PD0325901-based von Hippel-Lindau-recruiting PROTAC degrader for MEK1 and MEK2. MS432 displays good plasma exposure in mice, exhibiting DC50 values of 31 nM and 17 nM for MEK1, MEK2 in HT29 cells respectively[1].

MS432 (compound 23) is potent in reducing MEK1/2 protein levels in COLO 205 cells (DC50 (MEK1) = 18 ± 7 nM, DC50 (MEK2) = 11 ± 2 nM) and UACC257 cells (DC50 (MEK1) = 56 ± 25 nM, DC50 (MEK2) = 27 ± 19 nM).

MS432 (compound 23) displays good plasma exposure, which is approximately 3 to 20-fold higher than the GI50 values of compound 23 in the tested cancer cell lines[1].
