BDP5290 is a potent inhibitor of ROCK and MRCK with IC50 values of 17nM, 230nM, 123nM and 100nM for MRCKβ, ROCK1, ROCK2, respectively .
BDP5290 is a potent inhibitor of ROCK and MRCK with IC50 values of 17nM, 230nM, 123nM and 100nM for MRCKβ, ROCK1, ROCK2, respectively [1].
BDP5290 (2 μM, 24h) treated ATII cells decreased baseline TEER, and prevented the β1 subunit-induced increase of barrier integrity [2]. 3 μM BDP5290 completely inhibited MLC phosphorylation induced by MRCKβ, but not by ROCK1 or ROCK2 [1]. BDP5290 treated parental MDA-MB-231 breast cancer cells at varying concentrations, and showed endogenous MRCK and ROCK inhibition effect of pMLC with EC50 of 316 nM [1]. application of 0.5 μM BDP5290 lessened both cytoplasmic and cortical pMLC levels in MDA-MB-231 cells [1]. BDP5290 reduced MDA-MB-231 invasion at concentrations starting from 0.1 μM, with virtually complete inhibition at 10 μM [1]. 2-μM BDP5290 strongly inhibited the ability of human SCC12 squamous cell carcinoma cells to invade a 3D collagen matrix [1].

| Cell experiment [1]: | |
|
Cell lines |
Alveolar epithelial type II cells (ATII) |
|
Preparation Method |
ATII cells were cotransfected with plasmids (CMV-tet and Tet-β1) 24 hours after isolation and treated immediately with 2 μM MRCKα inhibitor BDP5290. transepithelial electrical resistance (TEER) was measured 24 hours later. |
|
Reaction Conditions |
2 μM for 24 hours |
|
Applications |
Consistent with siRNA silencing, baseline TEER was decreased upon MRCKα inhibition. BDP5290 treatment prevented the β1 subunit-induced increase of barrier integrity |
