PNU-142586
Based on 1 Customer Validation
PNU-142586 is the major metabolite of Linezolid (HY-10394). PNU-142586 can inhibit the activity of DNA topoisomerase 2-α (TOP2A) and DNA topoisomerase 2-β (TOP2B). PNU-142586 interferes with DNA replication and transcription by blocking the binding of DNA to TOP2 and inhibiting ATP hydrolysis, ultimately leading to antiproliferative and cytotoxic effects, including mitochondrial dysfunction. PNU-142586 can be used to study Linezolid-induced hematotoxicity and its molecular mechanism.
