MedKoo Cat#: 205856 | Name: ME-344

Description:

WARNING: This product is for research use only, not for human or veterinary use.

ME-344 is an active metabolite of NV-128, a novel flavonoid small molecule inhibitor of the mammalian Target of Rapamycin (mTOR), with potential antineoplastic activity. Upon administration, mTOR1/2 Kinase inhibitor ME-344 downregulates the PIK3/AKT/mTOR pathway and results in chromatin condensation in the absence of caspase activation. Consequently, this agent induces caspase-independent cell death in tumor cells with a de-regulated PIK3/AKT/mTOR pathway or chemotherapeutic resistant cells. In pre-clinical studies, ME-344 has shown tenfold more anti-tumor activity than NV-128.
