General description

A cell-permeable and orally active isothiouronium compound that potently and selectively disrupts the Rb/Raf-1 interaction (IC₅₀ = 77 nM in cell-free binding assays), while exhibiting no effect against Rb/B-Raf, Rb/E2F1, Rb/prohibitin, Rb/cyclin E, Rb/HDAC1, Raf-1/MEK1, or Raf-1/MEK2 interaction. Suppresses cellular E2F transcription activity and reduces serum-induced Rb phosphorylation. Shown to display Rb-dependent antitumor activity both in cultures in vitro and in mice in vivo.

Packaging

Packaged under inert gas

Preparation Note

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 1 month at -20°C. However, it is strongly recommended that stock solutions be prepared fresh just prior to each use.
