TOP1/TDP1-IN-1 is a DNA topoisomerase 1B (TOP1) and tyrosyl-DNA phosphodiesterase 1 (TDP1) inhibitor with a TDP1 IC50 of 17.8 μM. TOP1/TDP1-IN-1directly suppresses TOP1 catalytic activity without forming a DNA-TOP1 ternary complex, inhibits TDP1-mediated repair of TOP1-induced DNA damage, and exhibits low acute toxicity. TOP1/TDP1-IN-1 disrupts DNA repair pathways, induces apoptosis, suppresses clonogenic growth, and elicits antiproliferative effects in cancer cells. TOP1/TDP1-IN-1 can be used for the research of non-small cell lung cancer, cervical cancer, colon cancer.
