Methylene blue is a synthetic basic dye used in chromoendoscopy to identify dysplasia, or pre-cancerous lesions. It also can stain cells and tissues in research.It also works as a soluble guanylyl cyclase inhibitor.

描述 | Methylene blue (Basic Blue 9) inhibits guanylyl cyclase (sGC), monoamine oxidase A (MAO-A), and NO synthase (NOS). It acts as a vasopressor and is commonly used as a medical dye. Methylene blue impacts the nitric oxide synthase/guanylate cyclase signaling pathway to modulate prepulse inhibition and is a REDOX cycling compound that can cross the blood-brain barrier. Additionally, it inhibits Tau aggregation and is known to reduce cerebral edema, attenuate microglial activation, and lessen neuroinflammation[1][2][3]. |
体内研究 | Methylene blue (Basic Blue 9), administered at 50 and 100 mg/kg intraperitoneally once for 25 minutes in male NMRI mice, reduces the absence of prepulse inhibition[1]. Methylene blue (Basic Blue 9) administered at doses of 20 and 40 mg/kg orally each day for six months to CaMKIIα-tTA transactivator mice helps preserve cognitive function in mice that express full-length pro-aggregant human Tau[2]. Methylene blue (Basic Blue 9), administered intravenously at a dose of 2 mg/kg for one day to TBI-treated male BALB/c mice, decreases the levels of inflammatory factors[3]. |
体外研究 | Methylene blue (Basic Blue 9) at a concentration of 4.5 μM in BV2 microglia alters the immune profile of LPS-activated BV2 microglia, reducing levels of CD14, IL-1β, TNF-α, and CCL2 mRNA[3]. |
