Description: Sapanisertib, also known as TAK-228, MLN0128 and INK128, is a TORC1/2 inhibitor, is also an orally bioavailable inhibitor of raptor-mTOR (TOR complex 1 or TORC1) and rictor-mTOR (TOR complex 2 or TORC2) with potential antineoplastic activity. TORC1/2 inhibitor INK128 binds to and inhibits both TORC1 and TORC2 complexes of mTOR, which may result in tumor cell apoptosis and a decrease in tumor cell proliferation. TORC1 and 2 are upregulated in some tumors and play an important role in the PI3K/Akt/mTOR signaling pathway, which is frequently dysregulated in human cancers.

Additional Information

NK128 is an orally-available, potent and selective TORC1/2 inhibitor. INK128 has demonstrated broad preclinical anti-tumor activity against a range of solid tumor types. Potent inhibition was observed in cell lines resistant to rapamycin and pan-PI3K inhibitors.  Unlike other drugs targeting this pathway, INK128 inhibits the kinase activity associated with both the TORC1 and TORC2 complexes of the mTOR kinase. This dual TORC1 and TORC2 activity differentiates INK128 from rapamycin and various related analogs, or rapalogs, which only interfere with TORC1 activity, allowing for feedback loops that may actually augment tumor growth. In contrast, inhibition of both TORC1 and TORC2 may allow for improved efficacy and ultimately greater therapeutic potential for patient benefit.
