生物活性

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.

体外研究

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).

Cell Viability Assay

Cell Line: (HT-29, SK-MEL-28, COLO 205 and UACC 257 cell lines.
Concentration: 0-1 μM.
Incubation Time: 72 hours.
Result: Effectively inhibited proliferation of these CRC and melanoma cells in a concentration-dependent manner, with GI50 values ranging from 30 to 200 nM.
体内研究

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.

Animal Model: Male Swiss Albino mice.
Dosage: 50 mg/kg (Pharmacokinetic Analysis).
Administration: IP
Result: Displays good plasma exposure with the maximum plasma concentration of 1,400 nM detected at 0.5 hour post dosing and plasma concentration of 710 nM at 8 hours post dosing.
