N-etilmaleimida

Descripción:

N-etilmaleimida es un compuesto orgánico caracterizado por su estructura de maleimida, que presenta un anillo de cinco miembros que contiene un grupo carbonilo y un átomo de nitrógeno. Es un líquido incoloro a amarillo pálido a temperatura ambiente, exhibiendo un olor distintivo. Este compuesto es conocido por su reactividad, particularmente en la formación de enlaces covalentes con nucleófilos, lo que lo convierte en un reactivo valioso en la síntesis orgánica y la bioquímica. N-etilmaleimida se utiliza a menudo en la modificación de proteínas y péptidos, ya que puede reaccionar selectivamente con grupos tiol, facilitando el estudio de la estructura y función de las proteínas. Además, se utiliza en la producción de polímeros y como agente de entrecruzamiento en varios procesos químicos. El compuesto es soluble en disolventes orgánicos como acetona y etanol, pero tiene una solubilidad limitada en agua. Se deben tomar precauciones de seguridad al manipular N-etilmaleimida, ya que puede ser irritante para la piel y los ojos, y son necesarias condiciones de almacenamiento adecuadas para mantener su estabilidad.

N-Ethyl maleimide

CAS: 128-53-0

N-Ethyl maleimide is a cytosolic calcium chelator that binds to the calcium ions in the cells. It has been shown to inhibit the enzymes of fatty acid synthesis and phospholipase A2, which are involved in lipid metabolism. N-Ethyl maleimide is an irreversible enzyme inhibitor and can be used as a chemical tool for cell sample preparation. The reaction with N-ethyl maleimide leads to a decrease in water permeability of the cell membrane. This chemical also has a high affinity for sulfhydryl groups and can therefore be used as an anti-oxidant or free radical scavenger.
