| Description | Ro24-7429 is an effective and orally active antagonist of HIV-1 transactivator protein Tat and an inhibitor of a runt-related transcription factor 1. Ro24-7429 has anti-HIV, antifibrotic, and anti-inflammatory effects. |
| In vitro | Ro24-7429 (50-200 μM; 24-72 hours) strongly inhibits the proliferation of A549 and HLF cells in a dose-dependent manner. Ro24-7429 treatment (75 μM) significantly reduces TNF-α-induced up-regulation of RUNX1 mRNA by 50% at 48 hours[1]. Ro 24-7429 (1-25 μM) induces apoptosis and inhibits antigen-induced lymphocyte proliferation. Ro 24-7429 (0.1 μM, 1 μM, 5 μM; 3 days) induces apoptosis of cultured PBMCs in a dose-dependent manner[2]. |
| In vivo | Ro24-7429 (17.5-70 mg/kg; i.p.) curbs expression of fibrosis markers in injured mouse lungs. Ro24-7429 robustly ameliorates lung fibrosis and inflammation in the Bleomycin-induced pulmonary fibrosis mouse model[1]. |
