Citicoline
Based on 4 publication(s) in Google Scholar
Citicoline is an endogenous intermediate in the synthesis of phosphatidylcholine which is a component of cell membranes. Citicoline inhibits reactive oxygen species (ROS) and apoptosis. Citicoline can be used for neurological disease and hearing loss study.

Citicoline (1-100 μM, 24 h or 24 h before glutamate treatment) increases rats retinal cells viability after glutamate-induced excitotoxicity, and has synergistic effects with Tramiprosate (Homotaurine) (HY-14602)[1].
Citicoline (100 μM, 24 h before glutamate treatment and 30 min before HG treatment) decreases proapoptotic effects associated with neuroretinal degeneration such as glutamate-induced excitotoxicity and high glucose (HG)-induced neurotoxicity, and has synergistic effects with Tramiprosate in rats retinal cells[1].
Citicoline (100 μM, 36-48 h) reduces apoptosis in mice cochlear hair cells (HCs) and HEI-OC-1 cells after Neomycin (HY-150520) exposure, decreases the mRNA level of pro-apoptotic factor and increases anti-apoptotic factor, suppresses proapoptotic protein expression[2][3].
Citicoline (100 μM, 36-48 h) attenuates oxidative stress in mice cochlear HCs and HEI-OC-1 cells after Neomycin injury[3].

Cell Line:Rat retinal cells
-
Concentration:1, 10, 100 μM
-
Incubation Time:24 h or 24 h before glutamate treatment (100 μM)
-
Result:Did not affect viability of primary retinal cultures.
Significantly increased cell viability after glutamate-induced excitotoxicity, and had synergistic effects with homotaurine
-
Cell Line:Rat retinal cells
-
Concentration:100 μM
-
Incubation Time:24 h before glutamate treatment and 30 min before HG treatment
-
Result:Reduced apoptosis induced by administration of glutamate and HG, and had synergistic effects with homotaurine.
-
Cell Line:HEI-OC-1, mice cochlear tissue
-
Concentration:10 μM
-
Incubation Time:36 or 48 h (pretreatment for 12 h and then treated with 10 mM neomycin together for 12 and 24 h in cochlear tissue and HEI-OC-1, respectively, then allowed to recover in culture medium for another 12
-
Result:Showed significantly lower numbers of cleaved caspase 3-positive cells and TUNEL-positive cells than the neomycin-only group.
Significantly reduced the percentage of apoptosis.
The protein levels of cleaved caspase 3 were decreased compared with the Neomycin-only group.
Decreased the pro-apoptotic factor Bax, Casp3, Casp8, and Casp9, and increased anti-apoptotic factor Bcl-2 by qPT-PCR analysis.

Animal Model:Male C57Bl/6 mice (23-27 g) (The solution of convulsant pentylenetetrazole (1%) was infused intravenously at a flow rate of 0.01 ml/sec.)[2]
-
Dosage:500, 1000 mg/kg
-
Administration:Intraperitoneal injection (i.p.); 1 h before test
-
Result:Increased the threshold of clonic seizures and tonic phase of seizures with lethal outcome in a dose of 500 mg/kg.
The anticonvulsant effect was most pronounced in a dose of 1000 mg/kg.
