Fasudil Hydrochloride Hydrate

Uses

Fasudil (HA-1077; AT877) hydrochloride semihydrate is a nonspecific RhoA/ROCK inhibitor and also has inhibitory effect on protein kinases, with an Ki of 0.33 μM for ROCK1, IC50s of 0.158 μM and 4.58 μM, 12.30 μM, 1.650 μM for ROCK2 and PKA, PKC, PKG, respectively. Fasudil hydrochloride semihydrate is also a potent Ca2+ channel antagonist and vasodilator[1][2][3].

Definition

ChEBI: Fasudil hydrochloride hydrate is a hydrate that is the hemihydrate form of fasudil hydrochloride. It is a drug indicated for the prevention of cerebral vasospasm and ensuing cerebral ischemia following surgery for subarachnoid hemorrhage. It has a role as an antihypertensive agent, a calcium channel blocker, an EC 2.7.11.1 (non-specific serine/threonine protein kinase) inhibitor, a neuroprotective agent, a nootropic agent and a vasodilator agent. It contains a fasudil hydrochloride.
