Ro 5-3335, 7-chloro-5-(2-pyrryl)-3H-1,4-benzo-diazepin-2-(H)-one, is a benzodiazepine compound. Originally Ro 5-3335 was shown to inhibit gene expression controlled by the human immunodeficiency virus-1 (HIV-1) LTR promoter. The inhibition was specific for the viral transcriptional transactivator Tat. The compound did not inhibit the basal activity of the HIV-1 LTR or the activity of promoters not responsive to Tat. In addition Ro 5-3335 was able to interact with RUNX1 and CBFβ directly, repress RUNX1/CBFB-dependent transactivation in reporter assays, and repress runx1-dependent hematopoiesis in zebrafish embryos. Ro5-3335 preferentially killed human CBF leukemia cell lines, rescued preleukemic phenotype in a RUNX1-ETO transgenic zebrafish, and reduced leukemia burden in a mouse CBFB-MYH11 leukemia model.

Sample Use Guides

In Vivo Use Guide

Male C57BL/6 mice (8–10 weeks old) received an intraperitoneal injection of the RUNX1 inhibitor, Ro 5-3335 (5 mg/kg), with 5% DMSO in PBS or 5% DMSO in PBS for 3 h, following by an intraperitoneal injection with a lethal (20 mg/kg) or sublethal dose (10 mg/kg) of LPS to induce LPS shock as described previously. Treatment with the RUNX1 inhibitor, Ro 5-3335, protected mice from LPS-induced endotoxic shock and substantially reduced the IL-6 levels.

Route of Administration: Intraperitoneal

In Vitro Use Guide

Ro 5-3335 inhibited HIV-1 replication (IC50 = 0.1-1 microM) by reducing viral RNA synthesis in acutely, as well as chronically, infected cells in vitro. Ro 5-3335 selectively reduces viability of human CBF leukemia cells in culture with IC50 values in micromolar range.
