CRM1 inhibitors are a class of compounds designed to disrupt the function of Chromosome Region Maintenance 1 (CRM1) protein. This protein plays a crucial role in regulating the movement of proteins and RNAs between the cell nucleus and cytoplasm. Inhibiting CRM1 can halt the inappropriate export of tumor suppressor proteins, contributing to the development of potential cancer therapies. These inhibitors have garnered significant interest in cancer research as they hold promise for blocking this uncontrolled cellular transport and inhibiting cancer growth.
