Methylene Blue 10+ Cited Publications Basic Blue 9; CI-52015; Methylthioninium chloride	Classification of Application Fields Disease Research Fields Cancer	Guanylate Cyclase Monoamine Oxidase NO Synthase Microtubule/Tubulin
Methylene blue (Basic Blue 9) is a guanylyl cyclase (sGC), monoamine oxidase A (MAO-A) and NO synthase (NOS) inhibitor. Methylene blue is a vasopressor and is often used as a dye in several medical procedures. Methylene blue through the nitric oxide syntase/guanylate cyclase signalling pathway to reduce prepulse inhibition. Methylene blue is a REDOX cycling compound and able to cross the blood-brain barrier. Methylene blue is a Tau aggregation inhibitor. Methylene blue reduces cerebral edema, attenuated microglial activation and reduced neuroinflammation .

D-Luciferin Maximum Cited Publications 43 Publications Verification D-(-)-Luciferin; Firefly luciferin; Beetle Luciferin	Natural Products Animals Source classification Other Diseases Disease Research Fields	Fluorescent Dye
D-luciferin is the natural substrate of the enzyme luciferase (Luc) that catalyzes the production of the typical yellowgreen light of fireflies. The 560 nm chemiluminescence from this reaction peaks within seconds, with light output that is proportional to luciferase concentration when the substrate luciferin is present in excess. The luciferase (luc) gene is a popular reporter gene for research and agent screening. Chemiluminescent techniques are virtually background-free, making the luc reporter gene ideal for detecting low-level gene expression. As little as 0.02 pg of luciferase can be reliably measured in a standard scintillation counter. In addition to its role as a reporter of gene expression, luciferase is commonly used in an extremely sensitive assay for ATP . We of er the firefly luciferase (HY-P1004), luciferin free acid (HY-12591A), as well as its water-soluble sodium salts (HY-12591) and potassium salts (HY-12591B) .
