In vitro study | VS-5584 is an ATP-competitive inhibitor that selectively inhibits the PI3K/mTOR signaling pathway with comparable effects and inhibition of all human PI3K subtypes and mTOR kinases. VS-5584 was about 10-fold more selective for HMLE breast cancer cells than for cancer stem cells, with an EC50 value of 15 nM. VS-5584 preferentially reduced CD44 in HMLER immortalized breast cancer cell lines a large number of human cancer cell lines (436 strains) showed extensive anti-proliferative sensitivity, and cells containing the PI3KCA mutation were generally more sensitive to VS-5584 treatment. In FLT3-ITD cells mutated in MV4-11, VS-5584 inhibited pAkt(S473) and pAKT(T308) with IC50 of 12 nM and 13 nM, respectively. VS-5584 inhibited pS6 (S240/244), pAkt (S473) and pAkt (T308) with IC50 of 20 nM,23 nM, and 15 nM, respectively. |
In vivo study | In mice with triple-negative breast cancer, oral doses of VS-5584 reduced tumor stem cells and induced tumor regression in a taxane-resistant model. PTEN |

in vitro study | VS-5584 is a competitive inhibitor of ATP, selectively inhibiting PI3K/mTOR signaling pathway, and its effect is equivalent to inhibiting all PI3K subtypes and mTOR kinase. The selectivity of VS-5584 for HMLE breast cancer cells is about 10 times higher than that of cancer stem cells, and the EC50 value is 15 nM. VS-5584 preferentially reduces CD44 in HMLER immortalized breast cancer cell lines. A large number of human cancer cell lines (436 strains) show extensive antiproliferative sensitivity. Cells containing PI3KCA mutations are usually more sensitive to VS-5584 therapy. In FLT3-ITD mutated MV4-11 cells, VS-5584 inhibited pAkt(S473) and pAKT(T308) with IC50 of 12 nM and 13 nM, respectively. VS-5584 inhibits pS6 (S240/244), pAkt (S473) and pAkt (T308),IC50 is 20 nM,23 nM, and 15 nM respectively. |
