MS5128
MS5128 is an OTUB1-based deubiquitinase-targeting chimera (DUBTAC) targeting CFTR. MS5128 recruits OTUB1 to CFTR to induce deubiquitination and stabilization of CFTR. MS5128 can be used for the research of cystic fibrosis. (Blue: CFTR Ligand (HY-183724); Pink: OTUB1 Ligand (HY-13262); Black: Linker)

MS5128 (Compound 43) (0.5-10 μM; 3-24 h) increases ΔF508-CFTR protein levels in a concentration- and time-dependent manner in CFBE41o-4.7 ΔF508-CFTR cells, with maximal stabilization observed at 10 μM for 18 h, and this effect depends on engagement of both CFTR and OTUB1[1].
MS5128 (10 μM; 24 h) does not change CFTR mRNA levels in CFBE41o-4.7 ΔF508-CFTR cells after 24 h of treatment at 10 μM, indicating its CFTR-stabilizing effect is post-transcriptional[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Result:Significantly increased the CFTR protein level compared to vehicle control after 24 h of treatment with 10 μM MS5128.
Increased the CFTR protein level in a time-dependent manner, with detectable elevation at 6 h and maximal stabilization at 18 h of treatment with 10 μM MS5128.
Abolished its CFTR-stabilizing effect when cotreated with either 25 μM Lumacaftor (HY-13262) or 25 μM compound 34 at 10 μM for 24 h.
Drastically reduced MS5128-induced CFTR stabilization when OTUB1 was depleted via lentiviral sgRNA transduction with 10 μM MS5128 for 24 h.
