LMP517
Based on 1 Customer Validation
LMP517 (NSC 781517) is a potent and non-camptothecin Topoisomerase I and II (TOP1 and TOP2) dual inhibitor. LMP517 can induce TOP1 and TOP2 cleavage complexes (TOP1ccs and TOP2ccs). LMP517 can induce cancer cells DNA damage and γH2AX production. LMP517 can be used for the research of cancer, such as small cell lung cancer.
