Description | VS-5584 (SB2343) is a potent and selective dual PI3K/mTOR inhibitor for mTOR, PI3Kα/β/δ/γ with IC50 of 3.4 nM and 2.6-21 nM, respectively. Phase 1. | ||||||||||

In vitro | VS-5584 is an ATP-competitive inhibitor which selectively inhibits PI3K/mTOR signaling with equivalent low nanomolar potency against all human Class I PI3K isoforms and mTOR kinase. VS-5584 is approximately 10-fold selective for cancer stem cells with an EC50 of 15 nM in HMLE breast cancer cells. VS-5584 preferentially decreases CD44Hi/CD24Lo cells in an HMLER immortalized mammary cancer cell line. In SUM159 cells, VS-5584 effectively eliminates the cancer stem cell side population. [1] A large human cancer cell line panel screen (436 lines) reveals broad antiproliferative sensitivity and that cells harboring mutations in PI3KCA are generally more sensitive toward VS-5584 treatment. In the FLT3-ITD harboring MV4-11 cells, VS-5584 blocks pAkt (S473) and pAkt (T308) with IC50 of 12 and 13 nM, respectively. The IC50 of VS-5584 for pS6 (S240/244), pAkt (S473), and pAkt (T308) are 20, 23, and 15 nM, respectively. [2] | ||||||||||
In vivo | In mice bearing triple negative breast cancer tumors, oral dosing of VS-5584 decreases tumor cancer stem cells and induces tumor regression in taxane-resistant models. [1] In a PTENnull human prostate PC3 xenograft model, treatment with VS-5584 leads to significant tumor growth inhibition (TGI) of 79% and 113% for 11 and 25 mg/kg, respectively. In a FLT3-ITD AML xenograft model, VS-5584 treatment induces dose-dependent inhibition of tumor growth (28% for 3.7 mg/kg and 76% for 11 mg/kg). [2] |
