Background and Purpose : Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with no effective treatment. Fasudil hydrochloride (fasudil), a potent rho kinase (ROCK) inhibitor, is useful for the treatment of ischemic diseases. In previous reports, fasudil improved pathol. in mouse models of Alzheimer’s disease and spinal muscular atrophy, but there is no evidence in that it can affect ALS. We therefore investigated its effects on exptl. models of ALS. Exptl. Approach : In mice motor neuron (NSC34) cells, the neuroprotective effect of hydroxyfasudil (M3), an active metabolite of fasudil, and its mechanism were evaluated. Moreover, the effects of fasudil, 30 and 100 mg·kg-1, administered via drinking water to mutant superoxide dismutase 1 (SOD1G93A) mice were tested by measuring motor performance, survival time and histol. changes, and its mechanism investigated. Key Results : M3 prevented motor neuron cell death induced by SOD1G93A. Furthermore, M3 suppressed both the increase in ROCK activity and phosphorylated phosphatase and tensin homolog deleted on chromosome 10 (PTEN), and the reduction in phosphorylated Akt induced by SOD1G93A. These effects of M3 were attenuated by treatment with a PI3K inhibitor (LY294002). Moreover, fasudil slowed disease progression, increased survival time and reduced motor neuron loss, in SOD1G93A mice. Fasudil also attenuated the increase in ROCK activity and PTEN, and the reduction in Akt in SOD1G93A mice. Conclusions and Implications : These findings indicate that fasudil may be effective at suppressing motor neuron degeneration and symptom progression in ALS. Hence, fasudil may have potential as a therapeutic agent for ALS treatment. In the experiment, the researchers used many compounds, for example, 5-((1,4-Diazepan-1-yl)sulfonyl)isoquinoline hydrochloride (cas: 105628-07-7Application In Synthesis of 5-((1,4-Diazepan-1-yl)sulfonyl)isoquinoline hydrochloride).
5-((1,4-Diazepan-1-yl)sulfonyl)isoquinoline hydrochloride (cas: 105628-07-7) belongs to isoquinoline derivatives. Although isoquinoline derivatives can be synthesized by several methods, relatively few direct methods deliver the unsubstituted isoquinoline. Most traditional methods of generating isoquinoline do so via oxidative aromatization of dihydro- or tetrahydro-isoquinolines, usually offering some environmental or economic advantage.Application In Synthesis of 5-((1,4-Diazepan-1-yl)sulfonyl)isoquinoline hydrochloride
