FR 236924 is a PKCε activator, which may be useful as therapeutic agents for the treatment of Alzheimer disease as lowered PKCε activator levels are assocaited with Aβ degradation (a hallmark of Alzheimer’s disease). | [Biological Activity]
fr 236924 is a selective activator of pkc-ε [1].pkc is a monomeric ca2+- and phospholipid-dependent ser/thr protein kinase and plays an important role in growth factor-activated signaling and malignant transformation.fr 236924 (dcp-la) is a selective pkc-ε activator. in pc-12 cells, dcp-la (10 nm-100 μm) activated pkc in a concentration dependent way with the maximal effect at 100 nm. in the cell-free system, dcp-la (100 μm) significantly activated pkc-ε and exhibited >7-fold potency over other pkc isozymes (α,βi, βii, γ, δ, μ, η and ζ), suggesting that dcp-la was a selective pkc-ε activator. dcp-la exhibited the maximal effect on pkc-ε at 100 μm. the activation of pkc-ε induced by dcp-la (100 μm) was inhibited by dioleoyl-phosphatidylserine in a concentration dependent way, suggesting that dcp-la might bound to the phosphatidylserine binding site on pkc-ε. however, dioleoyl-phosphatidylserine increased dcp-la (100 μm)-induced pkc-ε activation in a concentration dependent way, suggesting a different activation mechanism [1]. in xenopus oocytes expressing α7 receptors, fr236924 (10 μm) induced a persistent increased α7 receptor responses to 144% via a pkc pathway. in rat hippocampal slices, fr236924 (10 nm to 10 μm) facilitated hippocampal neurotransmission [2].in the hippocampus of rats, fr236924 induced glutamate release and facilitated hippocampal synaptic transmission through pkc [3]. | [Biochem/physiol Actions]
DCP-LA is a selective PKC-epsilon (PKC-ε) activator. In the in situ PKC assay with a reversed phase high-performance liquid chromatography, DCP-LA significantly activated PKC in PC-12 cells in a concentration (10 nM-100 μM)-dependent manner, with the maximal effect at 100 nM. DCP-LA has over a 7-fold greater potency for activation of PKC-ε over other PKC isozymes. | [in vivo]
DCP-LA (1 mg/kg; p.o.; once daily; 7 d) exhibits a protective effect against ischemic brain damage, decreasing cerebral cortical defect due to middle cerebral artery (MCA) occlusion in mouse model[3].
| Animal Model: | Middle cerebral artery (MCA) occlusion in mouse model (male CB-17 mice, 5-8 weeks old)[3] | | Dosage: | 1 mg/kg | | Administration: | Oral gavage; once daily for 7 days; sacrificed mice on days 28 | | Result: | Significantly diminished degraded area due to cerebral infarction, with the rescued area reaching 82%. |
