Ro24-7429 is a potent and orally active HIV-1 transactivator protein Tat antagonist. Ro24-7429 is also a runt-related transcription factor 1 (RUNX1) inhibitor. Ro24-7429 has anti-HIV, antifibrotic and anti-inflammatory effects[2].In Vitro: Ro 24-7429 (0.1-5 μM; 3 days) induces apoptosis of cultured PBMCs in a dose-dependent manner.
Ro 24-7429 (1-25 μM) also induces apoptosis and inhibits antigen-induced lymphocyte proliferation.
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[2].In Vivo: Ro24-7429 (17.5-70 mg/kg; i.p.; daily; for 14 or 21 days) treatment robustly ameliorates lung fibrosis and inflammation in the Bleomycin-induced pulmonary fibrosis (PF) mouse model. Ro24-7429 curbs expression of fibrosis markers in injured mouse lungs[2].
