Indimitecan, also known as LMP776, is a novel topoisomerase I inhibitor. A substance being studied in the treatment of cancer. It blocks certain enzymes that break and rejoin DNA strands. These enzymes are needed for cells to divide and grow. Blocking them may cause cancer cells to die. Indimitecan (LMP776) also helps anticancer drugs kill cancers that are resistant to some other drugs. LMP776 is a type of indenoisoquinoline and a type of topoisomerase inhibitor. In vitro, LMP776 induces TOP 1 cleavage at unique genomic positions and causes cell cycle arrest in both S and G (2)-M phases. Protein linked DNA breaks were observed in cells treated with nanomolar concentrations of LMP776.

Sample Use Guides

In Vivo Use Guide

Indimitecan (LMP 776) administered IV daily x 5 d. Dose level (DL) in mg/m2/day for LMP 776: 1, 2, 3, 4.5 mg

Route of Administration: Intravenous

In Vitro Use Guide

Exponentially growing CEM cells were treated for 1 h with 1 umol/L of Indimitecan (NSC 725776) and processed in the ICE bioassay. NSC 725776 was cytotoxic to the wild-type P388 (IC50 25 nmol/L), MCF-7 (IC50 93 nmol/L), and HCT-116 (IC50 125 nmol/L) cells. Human colon carcinoma HT29 cells were treated with varying doses of NSC 725776 for 6 h. At the lowest concentration used (0.01 umol/L), drug-treated cells accumulated in the G2-phase of the cell cycle. With increasing drug concentrations (>/=0.05 umol/L), the cells also showed an S-phase accumulation.
