Top2a inhibitor
Web1. feb 2024 · TOP2 inhibitors are classified into two types: TOP2 poisons and catalytic inhibitors ( 1, 4, 14 ). Poisons ( e.g., etoposide) stabilize the covalent TOP2–DNA cleavage complex, resulting in DNA damage that can cause cell death ( 4, 15 ). Currently, topoisomerase inhibitors hold a prominent place among antibiotics and anticancer drugs in active medical use, as inhibitors like doxorubicin (anthracycline, TopII inhibitor), etoposide (TopII inhibitor), ciprofloxaxin (fluoroquinolone, TopII inhibitor), and irinotecan (camptothecin derivative, TopI … Zobraziť viac Topoisomerase inhibitors are chemical compounds that block the action of topoisomerases, which are broken into two broad subtypes: type I topoisomerases (TopI) and type II topoisomerases (TopII).
