Fasudil (HA-1077; AT877) dihydrochloride 是一种非特异性RhoA/ROCK抑制剂，并抑制蛋白激酶。Fasudil dihydrochloride 抑制ROCK1的Ki为 0.33 μM，抑制ROCK2，PKA，PKC，PKG的IC50分别为 0.158 μM 和 4.58 μM，12.30 μM，1.650 μM。Fasudil dihydrochloride 也是一种有效的 Ca2+通道拮抗剂和血管扩张剂。

Fasudil (HA-1077; AT877) dihydrochloride is a nonspecific RhoA/ROCK inhibitor and also has inhibitory effect on protein kinases, with an K i of 0.33 μM for ROCK1, IC 50 s of 0.158 μM and 4.58 μM, 12.30 μM, 1.650 μM for ROCK2 and PKA, PKC, PKG, respectively. Fasudil dihydrochloride is also a potent Ca 2+ channel antagonist and vasodilator [1] [2] [3].

Fasudil dihydrochloride (100 μM) inhibits cell spreading, the formation of stress fibers, and expression of α-SMA with concomitant suppression of cell growth in rat HSCs (hepatic stellate cells) and human HSC-derived TWNT-4 cells [4]. Fasudil dihydrochloride (50-100 μM; 24 hours) inhibits the LPA (lysophoaphatidic acid)-induced phosphorylation of ERK1/2, JNK, and p38 detected by western blotting in rat HSCs and human HSC-derived TWNT-4 cells [4]. Fasudil dihydrochloride (25-100 μM; 24 hours) suppresses transcription of collagen and TIMP, stimulates transcription of MMP-1 in human HSC-derived TWNT-4 cells [4]. Western Blot Analysis [4] Cell Line: Rat HSCs and human HSC-derived TWNT-4 cells Concentration: 50 μM; 100 μM Incubation Time: 24 hours Result: Suppressed the LPA-induced phosphorylation of ERK1/2, JNK and p38 MAPK by 60%, 70%,and 90%, respectively. RT-PCR [4] Cell Line: Rat HSCs and human HSC-derived TWNT-4 cells Concentration: 25 μM; 50 μM; 100 μM Incubation Time: 24 hours Result: Reduced the expression of type I collagen, a-SMA, and TIMP-1.

Fasudil dihydrochloride (10 mg/kg; i.v.; 1 h before operation) exhibits protectable effects on cardiovascular disease and reduces the activation of JNK and attenuates mitochondrial-nuclear translocation of AIF under ischemic injury [5]. Fasudil dihydrochloride (50 mg/kg/d; i.p.) inhibits acute and relapsing EAE (experimental autoimmune encephalomyelitis) induced by proteolipid protein PLP p139-151, reduces lymphocytes proliferation, results downregulation of interleukin (IL)-17 and a marked decrease of the IFN-γ/IL-4 ratio [6]. Fasudil dihydrochloride (100 mg/kg/d; p.o.) significantly reduces incidence and pathological examination score of EAE (experimental autoimmune encephalomyelitis) in SJL/J mice, decreases inflammation, demyelination, axonal loss and APP positivein spinal cord in mice [6]. Animal Model: Myocardial ischemia and reperfusion in rat (250-300 g) [5] Dosage: 10 mg/kg Administration: Intravenous injection; 1 h before operation Result: Activated the Rho-kinase, JNK, and resulted AIF translocated to the nucleus. Inhibited Rho-kinase activity, and reduced myocardial infarct size and heart cell apoptosis.
