Top1

In Vitro Indimitecan (LMP776) (0-100 μM) shows antiproliferative potencies against various human cancer cell lines, with mean-graph midpoint (MGM) of 0.079 ± 0.023 μM[1]. Indimitecan shows potent DNA cleavage due to Top1 inhibition[1]. Indimitecan can be substrates for metabolic ketone reductases[1]. Cell Proliferation Assay[1] Cell Line: HOP-62, HCT-116, SF-539, UACC-62, OVCAR-3, SN12C, DU-145, MCF-7 Concentration: 0-100 μM Incubation Time: Result: Showed growth inhibition with GI50s of <0.01, <0.01, 0.04, <0.01, 0.08, <0.01, <0.01 and 0.01 μM against HOP-62, HCT-116, SF-539, UACC-62, OVCAR-3, SN12C, DU-145 and MCF-7 cells, respectively. And the mean-graph midpoint (MGM) for growth inhibition of all human cancer cell lines successfully tested (the National Cancer Institute’s developmental therapeutics assay (the “NCI60”)) was 0.079 ± 0.023 μM.
