Novel, cell-permeable inhibitor of protein kinase Mζ (PKMζ), a constitutively active, atypical PKC isozyme involved in LTP maintenance. Selectively blocks PKMζ-induced synaptic potentiation in hippocampal slices in vitro. Reverses late-phase LTP (IC50 = 1 - 2.5 μM) and produces persistent loss of 1-day-old spatial memory following central administration in vivo.

Solamargine is a major steroidal alkaloid glycoside extracted from a traditional Chinese medicine herb, Solanum nigrum L. (SNL); has been shown to inhibit growth and induce apoptosis of various cancer cells.

PKC-IN-7 is a potent, selective, reversible, ATP-competitive PKCα/β inhibitor with IC50 of 4.7/3.3 nM.
