General description

A cell-permeable powerful DNA topoisomerase I inhibitor. Reduces DNA synthesis in vitro in murine hepatoma cells. Has selective inhibitory effect on the phosphorylation of histone H1 and H3, but less effect on other histones.
A cell-permeable, powerful DNA topoisomerase I inhibitor. Reduces DNA synthesis in vitro in murine hepatoma cells. Inhibits the proliferation of hepatoma HepG2, Bcl-7402 and Bcl-7404 cells in a dose-dependent manner. Has selective inhibitory effect on the phosphorylation of histones H1 and H3, but is less effective on other histones.

Poly (ADP-ribose) polymerase inhibitor (PARPi)-based therapies initially reduce tumor burden but eventually lead to acquired resistance in cancer patients with BRCA1 or BRCA2 mutation. To understand the potential PARPi resistance mechanisms, we performed whole-genome CRISPR screens to discover genetic alterations

Nuclear factor erythroid-2 related factor-2 (Nrf2) is an oxidative stress-response transcriptional activator that promotes carcinogenesis through metabolic reprogramming, tumor promoting inflammation, and therapeutic resistance. However, the extension of Nrf2 expression and its involvement in regulation of breast cancer (BC) responses
