Safingol hydrochloride (L-threo-dihydrosphingosine hydrochloride) is a specific inhibitor of protein kinase C. It induces autophagy in solid tumor cells and cancer cell death by inhibiting the PKC and PI3-kinase pathways.BIIB 722 Mesylate is a selective sodium-hydrogen exchange inhibitor. Safingol hydrochloride inhibits PKC and PI3k.

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.
