Descripción

General description

A cell-permeable, nontoxic benzylstyrylsulfone based compound with anti-tumor and radiosensitizing properties. Potently suppresses PI 3-K/Akt/mTOR signaling pathway and activates Cdc25C phosphatases. Acts as an allosteric, substrate-competitive, and reversible inhibitor of multiple protein kinases (IC₅₀ = 32, 42, 182, 18 and 155 nM against Bcr-Abl, Flt1, Fyn, PDGFR, and Src, respectively). Induces DNA damage and blocks microtubule formation. Also shown to cause mitotic arrest and apoptosis in multiple types of cancer cells (GI₅₀ = 30 - 200 nM) and blocks cell cycle at G2/M phase. Effective against several multi-drug resistance tumor cells (IC₅₀ = 50-100 nM). Suppresses the growth of BT20 tumor xenografts in mice and improves their survival rate (200 mg/kg, i.v. Q2D X 20 schedule). However, it displays limited oral bioavailability.
