Methylene Blue trihydrate

SKU: orb1224147

Description

A compound consisting of dark green crystals or crystalline powder, having a bronze-like luster. Solutions in water or alcohol have a deep blue color. Methylene blue is used as a bacteriologic stain and as an indicator. It inhibits GUANYLATE CYCLASE, and has been used to treat cyanide poisoning and to lower levels of methemoglobin.

Bioactivity

• In Vivo:
  Methylene Blue (1, 5, and 25 μg/rat) significantly decreases sevoflurane minimum alveolar anesthetic concentration (MAC) and brain cyclic guanosine monophosphate (cGMP) content in a dose-dependent manner in male Sprague-Dawley rats (7-week-old, 200-250 g). Methylene blue is used as a dye in chromoendoscopy, and is sprayed onto the mucosa of the gastrointestinal tract in order to identify dysplasia, or pre-cancerous lesions. Methylene blue is able to restore vascular tone, normalize mean arterial pressures (MAP), and reduce vasopressor usage.
• In Vitro:
  By acting as an alternative electron acceptor/donor Methylene blue restores mitochondrial function, improves neuronal energy production and inhibits the formation of superoxide. Methylene blue inhibits cytochrome P450 (CYP) isozymes. Methylene blue is an odorless, water soluble, dark blue-green crystalline powder, which turns blue whenever mixed in solution. Methylene blue is a vasopressor that impacts the NO synthetic pathway by inhibiting inducible NOS and inhibiting the subsequent activation of sGC. In addition, by binding to the iron heme moiety of sGC and causing enzyme inhibition, Methylene blue blocks accumulation of cyclic GMP (cGMP), competing directly with NO in its ability to activate soluble guanylyl cyclase.
