Background

PQR620 is a novel brain penetrant dual TORC1/2 inhibitor with anti-tumor activity across 56 lymphoma cell lines with a median IC50 value of 250 nM after 72 h of exposure.[1]

PQR620 has in vivo anti-lymphoma activity and in vivo synergism with the BCL2 inhibitor venetoclax. The combination of PQR620 and venetoclax have stronger in vivo anti-tumor activity than the single agents in a xenograft model of GCB-DLBCL.[1]

Protocol

Cell experiment:

The drug concentration causing 50% inhibition of cell proliferation (IC50) is obtained in lymphoma cell lines [diffuse large B cell lymphoma (DLBCL); mantle cell lymphoma (MCL); anaplastic large T-cell lymphoma; and others] exposed to increasing doses of PQR620 for 72 h using a Tecan D300e Digital Dispenser on 384 well plates[2].

Animal experiment:

Mice[2]For in vivo experiments, NOD-Scid (NOD.CB17-Prkdcscid/J) mice are subcutaneously inoculated with 10×106 (RIVA) or with 5×106(SU-DHL-6) cells. Treatments with PQR620 (100mg/kg dose per day, Qdx7/w) started with 100-150 mm3 tumors and are carried for 14 (SU-DHL-6) or 21 days (RIVA).
