Description: Sapanisertib, also known as TAK-228, MLN0128 and INK128, is a TORC1/2 inhibitor, is an orally bioavailable inhibitor of raptor-mTOR (TOR complex 1 or TORC1) and rictor-mTOR (TOR complex 2 or TORC2) with potential antineoplastic activity. Sapanisertib binds to and inhibits both TORC1 and TORC2 complexes, which may result in tumor cell apoptosis and a decrease in tumor cell proliferation.

More Info: 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.

Biological target: Sapanisertib is an ATP-dependent mTOR1/2 inhibitor with an IC50 of 1 nM for mTOR kinase.
In vitro activity: Sapanisertib alleviates pulmonary fibrosis by targeting Wnt5a/mTOR/HIF-1α/p70S6K. In TGF-β1-treated A549 cells, sapanisertib suppresses epithelial-mesenchymal transition, increasing E-cadherin and reducing vimentin expression. In L929 cells exposed to TGF-β1, sapanisertib inhibits cell proliferation, decreases collagens I and III, smooth muscle actin, and key proteins like hypoxia-inducing factor, mTOR, p70S6K, and Wnt5a.

In vivo activity: Sapanisertib has potential to be developed as a clinical strategy to promote wound healing of diabetic patients. Sapanisertib could promote wound healing through reducing the myeloid-derived suppressor cells (MDSCs). MDSC function was disordered in diabetic mice and high-glucose environments, while sapanisertib could help retrieve their function.
