Topoisomerase

Topoisomerase

Topoisomerases are enzymes that regulate the topology of DNA during processes such as replication, transcription, and chromosome segregation by introducing transient breaks into the DNA strands to relieve torsional stress. Topoisomerase inhibitors interfere with this process, leading to the accumulation of DNA breaks and the induction of cell death, particularly in rapidly dividing cells. These inhibitors are widely used as chemotherapeutic agents in cancer treatment. At CymitQuimica, we offer a broad range of high-quality topoisomerase inhibitors to support your research in DNA replication, cancer therapy, and cell cycle regulation.
