SPR519

SPR519 is a selective, orally active dual PI3Kα/mTOR kinase inhibitor, with an IC₅₀ of 0.03 μM against PI3Kα and an IC₅₀ of 0.01 μM against mTOR. SPR519 exhibits anticancer effects in ovarian cancer and colon cancer xenograft models. SPR519 can be used for the research of solid tumors (ovarian cancer, colon cancer).

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
