TAK-243 (MLN7243) is a small molecule inhibitor of ubiquitin-activating enzyme (UAE), with potential antineoplastic activity, which was developed by Takeda Oncology, Millennium. MLN7243 binds to and inhibits UAE, which prevents both protein ubiquitination and subsequent protein degradation by the proteasome. This inhibits tumor cell proliferation and survival. UAE, also called ubiquitin E1 enzyme (UBA1; E1), is more active in cancer cells than in normal, healthy cells. Currently, TAK-243 is in phase I clinical trial evaluating safety, tolerability, pharmacokinetics, pharmacodynamics against advanced malignant solid tumors phase.
