Mechanism of Action

Targets/IC₅₀/Ki	ROCK (Cell-free assay) ~0.5 μM
In vitro	Although displaying little impact on cell proliferation, Thiazovivin treatment significantly enhances the survival of human embryonic stem cells (hESCs) after enzymatic dissociation more than 30-fold, while homogenously maintaining pluripotency with the characteristic colony morphology, expression of typical pluripotency markers such as alkaline phosphatase (ALP), and normal karyotype. Dissociated hESCs treated with this compound display dramatically increased adhesion to matrigel- or laminin-coated plates but not to gelatin-coated plates within a few hours. This chemical treatment increases cell-ECM adhesion-mediated β1 integrin activity, which synergizes with growth factors to promote cell survival. In addition to activating integrin, this compound but not Tyrintegin (Ptn) protects hESCs from death in the absence of ECM in suspension through E-cadherin-mediated cell-cell interaction. It potently inhibits endocytosis of E-cadherin, consequently stabilizing E-cadherin on the cell surface and leading to reestablishment of cell-cell interaction, which is essential for hESC survival in ECM-free conditions. This inhibitor but not Tyrintegin (Ptn) at 2 μM inhibits Rho-associated kinase (ROCK) activity and protects hESCs at a similar level as the widely used selective ROCK inhibitor Y-27632 at 10 μM, suggesting that Rho-ROCK signaling regulates cell-ECM and cell-cell adhesion. It at 1 μM increases the reprogramming efficiency of CB mononuclear cells to induced pluripotent stem cells (iPSCs) by more than 10 times.
