CAS 133343-34-7: Lactacistina
Descrição:Lactacistina é um composto que ocorre naturalmente e é conhecido principalmente por seu papel como inibidor do proteassoma. É derivado da bactéria *Streptomyces* e tem despertado interesse no campo da bioquímica e farmacologia devido à sua capacidade de inibir seletivamente o proteassoma, um complexo celular responsável pela degradação de proteínas ubiquitinadas. Essa inibição pode levar ao acúmulo de proteínas reguladoras, afetando assim vários processos celulares, incluindo a regulação do ciclo celular e a apoptose. Lactacistina é frequentemente utilizado em pesquisas para estudar o papel do proteassoma nas funções celulares e suas implicações em doenças como câncer e distúrbios neurodegenerativos. O composto é caracterizado por sua estrutura específica, que inclui um anel de lactona, contribuindo para sua atividade biológica. Embora tenha aplicações terapêuticas potenciais, o uso de Lactacistina em ambientes clínicos é limitado devido à sua toxicidade e à necessidade de mais pesquisas para entender completamente seus efeitos e mecanismos.
