General description

A cell-permeable isoquinolinesulfonamide compound that acts as a highly specific, potent, and ATP-competitive inhibitor of G-protein Rho-associated kinase (ROCK; Ki = 1.6 nM). Inhibits other serine/threonine kinases only at higher concentrations (Ki = 630 nM for PKA, 9.27 µM for PKC, and 10.1 µM for MLCK). Shown to selectively block lysophosphatidic acid-induced, but not PDBu-induced, phosphorylation of myristoylated alanine-rich C kinase substrate (MARCKS) in NT-2 cells (IC50 = 2.5 µM). Reported to be a more potent and selective inhibitor than Y-27632 (Cat. No. 688000 & 688001).
The InSolution Rho Kinase Inhibitor controls the biological activity of Rho Kinase. This small molecule/inhibitor is primarily used for Phosphorylation & Dephosphorylation applications.

TNBC represents the most aggressive breast cancer subtype. Although cancer stem cells (CSCs) are a minor fraction of all cancer cells, they are highly cancerous when compared to their non-stem counterparts, playing a major role in tumor recurrence and metastasis.

There are no targeted therapies for patients with triple-negative breast cancer (TNBC). TNBC is enriched in breast cancer stem cells (BCSC), which play a key role in metastasis, chemoresistance, relapse, and mortality. γδ T cells hold great potential in immunotherapy

Cancer cells, including melanoma cells, often metastasize regionally through the lymphatic system before metastasizing systemically through the blood1-4; however, the reason for this is unclear. Here we show that melanoma cells in lymph experience less oxidative stress and form more

Triple-negative breast cancer (TNBC) is a subtype of breast cancer characterized by the absence of estrogen and progesterone receptors (ER, PR) and lacking an overexpression of human epidermal growth factor receptor 2 (HER2). Apart from this lack of therapeutic targets
