About Antineoplastic-Selective Inhibitors of Nuclear Export(SINE).

Antineoplastic selective inhibitors of nuclear export (SINE) are a targeted class of anticancer agents that block nucleocytoplasmic transport in malignant cells.

They function primarily by binding to exportin 1 (XPO1, also known as CRM1), preventing the export of tumor suppressor proteins and growth regulatory factors out of the nucleus.

This targeted nuclear retention restores natural tumor-suppressive pathways, resulting in cell cycle arrest and selective apoptosis of neoplastic cells.

Clinically, representative agents such as selinexor are primarily indicated for hematologic malignancies, most notably relapsed or refractory multiple myeloma and diffuse large B-cell lymphoma.
