Norcantharidin is a potent and selective inhibitor of protein phosphatase 2A (PP2A). PP2A is a ubiquitous serine/threonine phosphatase that plays a crucial role in regulating a wide range of cellular processes, including cell growth, proliferation, and differentiation. Norcantharidin has been shown to have anti-cancer activity in vitro and in vivo, and is currently being investigated as a potential cancer therapeutic. Norcantharidin is synthesized through a multi-step process involving the extraction and modification of cantharidin, a naturally occurring compound found in blister beetles. The molecule's unique structure allows it to bind to and inhibit PP2A, thus disrupting the normal function of this essential enzyme. Researchers are studying norcantharidin to understand its potential therapeutic applications in cancer treatment and to further elucidate the role of PP2A in various cellular processes.'

Treatment by norcantharidin induced significant mitophagy and autophagy, as demonstrated by a decrease in Translocase Of Outer Mitochondrial Membrane 20 (TOM20), increased beclin1 and LC3-II protein expression, reduced protein SQSTM1/p62 expression, and accumulation of punctate LC3 in the cytoplasm of SK-N-SH cells. Treatment with norcanthan at 3mg/ml or higher significantly increased oligonucleosomal formation with concomitant appearance of PARP cleavage, implicating the induction of apoptosis.
