CX-5461

SKU: orb1306482

Description

CX5461 is an orally bioavailable small molecule that selectively inhibits RNA polymerase I, suppressing ribosomal RNA synthesis. This activity triggers a DNA damage response and demonstrates antitumor efficacy in preclinical models, including in vivo studies of ovarian cancer.

Bioactivity

• Target IC50:
  Pol I-driven transcription of rRNA:142 nM
• In Vivo:
  In a mouse model of xenograft human solid tumors, oral administration of CX-5461 (50 mg/kg) demonstrated antitumor activity against solid tumors.
• In Vitro:
  METHODS: The phytopathogenic fungi A. tubingensis, Nigrospora oryzae and Phoma herbarum were treated with Carviolin (1-512 µg/mL) for 18 h and subjected to Antifungal Assay. RESULTS: Carviolin showed antifungal activity with MIC less than 200 µg/mL against all three fungi.
• Cell Research:
  Cells are plated on 96-well plates and treated the next day with dose response of CX-5461 for 96 hours. Cell viability is determined using Alamar Blue and CyQUANT assays(Only for Reference)
