描述

一般說明

A cell-permeable phenylsulfonylbenzimidazole compound that is shown to dock in the ligand-binding pocket of both HNF4α and HNF4γ via in silico structural analyses and antagonizes HNF4α DNA binding activity (by 93% after 10 µM overnight treatment of HepG2 cells), effectively inhibiting HNF4α-dependent cellular activities, including HNF4α mRNA transcription (by 62% in murine insulinoma MIN6 and 84% in human hepatoma HepG2 cultures after 5 h and 48 h 5 µM inhibitor treatment, respectively) and OTC (omithine transcarbamoylase) promoter transcription (by 85% & >95% in human HNF4α-transfected HepG2 & CV-1 cells, respectively; 48 hr 1 µM treatment). HNF4γ inhibition by BI6015 is also reported to indirectly lead to decreased binding of transactivators, E47 & PDX-1, to insulin promoter in T6PNE cells (48 h 5 µM treatment). Although BI6015 is found to exhibit cancer-selective cytotoxicity toward a panel of 58 human cancer cells and Hep3B-Luc (Effective conc. 1 to 10 µM), but not primary murine hepatocytes, it does cause hepatic steatosis both in vitro (primary murine hepatocytes; 5 µM for 3 days) and in mice in vivo (10 to 30 mg/kg/day for 5 days via i.p.) and is effectively metabolized by liver enzymes, limiting its in vivo efficacy in treating human Hep3B-derived liver tumor in mice. BI6015 also inhibits Human CYP450 2C19 and rat L-type calcium channel (by 94% and 83%, respectively, at 10 µM), but not PPARγ or a panel of 41 receptors/enzymes of human, mouse, and rat origin.
