MS170 is a highly effective and specific PROTAC AKT degrader compound that exhibits potent activity. It efficiently reduces the levels of total AKT (T-AKT) within cells, with a DC 50 value of 32 nM. Furthermore, MS170 demonstrates strong binding affinity towards AKT isoforms, specifically AKT1, AKT2, and AKT3, with respective dissociation constants (Kd) of 1.3 nM, 77 nM, and 6.5 nM.This compound is unstable in powder form and other related salt forms are recommended.

Akt2:77 nM (Kd), Akt1:1.3 nM (Kd), Akt3:6.5 nM (Kd)

Cereblon (CRBN)-recruiting degrader MS170 is an effective AKT degrader without a ″hook effect″. MS170 selectively induces robust AKT protein degradation, inhibits downstream signaling, and suppresses cancer cell proliferation. MS170 concentration- and time-dependently induces AKT degradation through the ubiquitin-proteasome system (UPS)[1]. MS170 (10 nM-10 μM) effectively inhibits the proliferation in multiple cancer cell lines[1]. MS170 (1 nM-10 μM) concentration-dependently depletes cellular total AKT (T-AKT) with the DC 50 value of 32±18 nM[1]. Cell Proliferation Assay[1]Cell Line: BT474, PC3, and MDA-MB-468 cells Concentration: 10 nM, 100 nM, 1 μM, 10 μM Incubation Time: 5 days Result: Inhibited the cell growth with GI 50 s of 0.7±0.2 μM, 7.4±2.2 μM, and 5.7±2.4 μM for BT474 cells, PC3 cells, and MDA-MB-468 cells, respectively. Western Blot Analysis[1]Cell Line: BT474 cells Concentration: 1 nM, 3 nM, 10 nM, 30 nM, 100 nM, 300 nM, 1 μM , 3 μM, and 10 μM Incubation Time: 24 hours Result: Potently induced AKT degradation.

MS170 (a single intraperitoneal injection at a dose of 50 mg/kg) is bioavailable in mice via IP injection[1]. Animal Model: Male Swiss albino mice[1]Dosage: Single 50 mg/kg(Pharmacokinetic Analysis) Administration: IP injection over 8 h Result: Bioavailable in mouse PK studies. The C max is1.4 μM at 2 h.
