Description

Bimiralisib (PQR309) is a novel brain-penetrant dual inhibitor with in vitro and in vivo antilymphoma activity. It displays excellent selectivity versus PI3K-related lipid kinases, protein kinases and unrelated targets.

mTOR [2]
(Cell-free assay)

In vitro

PQR309 shows in vitro activity with a median IC50 value of 233 nmol/L (95% CI, 174-324 nmol/L) in most of the tesed lymphoma cell lines (increasing doses, 72 hours). The arrest in proliferation is mainly due to cell cycle arrest with a block in G1 rather than to apoptosis, limited to only 2/7 cell lines. PQR309 is more active in B-cell lymphoma cell lines (DLBCL, MCL, CLL, and SMZL) than in the T-cell derived ALCL. PQR309 inhibits PI3K/mTOR signaling in lymphoma cell lines. It has in vitro and in vivo antilymphoma activity as single agent and in combination.
