FX-11
Based on 28 publication(s) in Google Scholar
FX-11 is a potent, selective, reversible and competitive lactate dehydrogenase A (LDHA) inhibitor, with a Ki of 8 μM. FX-11 reduces ATP levels and induces oxidative stress, ROS production and cell death. FX-11 shows antitumor activity in lymphoma and pancreatic cancer xenografts.
