Product details
- Chemical name: 1-(5-Isoquinolinesulfonyl) homopiperazine, dihydrochloride salt.
- Also known as: Fasudil, Eril, AT-877
- CAS number: 103745-39-7
- Molecular formula: C14H17N3O2S•2HCl.
- Purity: >99%
- Concentration: >1 µM.
- Form: Lyophilized powder.
- Solubility: Water, DMSO. Centrifuge all product preparations before use (10000 x g 5 min).
- Reconstitution: Centrifuge the vial before adding solvent (10,000 x g for 5 minutes) to spin down all the powder to the bottom of the vial. The lyophilized product may be difficult to visualize. Add solvent directly to the centrifuged vial. Tap the vial to aid in dissolving the lyophilized product. Tilt and gently roll the liquid over the walls of the vial. Avoid vigorous vortexing. Light vortexing for up to 3 seconds is acceptable if needed. For long-term storage in solution, we recommend preparing a stock solution by dissolving the product in sterile water at a concentration of at least 0.1 mg/mL. Divide the stock solution into small aliquots and store at -20°C. Before use, thaw the relevant vial(s) and dilute to the desired working concentration in your working buffer. It is recommended to prepare fresh solutions in working buffers just before use. For long-term storage of diluted solutions, we recommend adding 0.1% BSA. Repeat freeze-thawing may result in loss of activity.
- Shipping: Shipped at room temperature. Product as supplied can be stored intact at room temperature for several weeks. For longer periods, it should be stored at -20°C.
- Target: Rho/Rok
- Source: Synthetic
- Activity: HA-1077 specifically inhibits the small GTPase - Rho through its associated kinase-Rho dependent kinase (ROK), thereby inhibiting myosin llight chain (MLC) phosphorylation1-3. It also acts as an intracellular Ca2+ antagonist4.
- Alternative names: Fasudil, Eril, AT-877
Scientific background
HA-1077 is a small, cell permeable derivative of isoquinoline which specifically inhibits the small GTPase - Rho by inhibition of its associated kinase-Rho dependent kinase (ROK). This signaling pathway acts as a molecular switch to control cytoskeleton organization in many cell types including smooth muscle.1-3 By inhibition of ROK, HA-1077 decreases the myosin light chain (MLC) phosphorylation induced by Ca2+ due to abrogating Rho-mediated inhibition of MLC dephosphorylation. HA-1077 also inhibits fetal calf serum-induced proliferation and [3H]thymidine incorporation into DNA of growth-arrested VSMC in a dose-dependent manner.4-6At concentrations higher than 5 µM, it induces disorganization of actin filament structure. This compound was also found to act as a vasodilator and antivasospasm drug which antagonizes the verapamil-insensitive voltage dependent Ca2+ channel and is used clinically for treatment of the cerebral vasospasm after subarachnoid hemorrhage.7-9
