Biological Activity

Description Citalopram HBr (Nitalapram HBr, Prepram HBr, Bonitrile HBr, Lu 10-171 HBr), an antidepressant, is an orally administered selective serotonin reuptake inhibitor (SSRI) with IC50 of 1.8 nM.

Citalopram (Lu 10-171), a new bicyclic phthalane derivative, is an extremely potent inhibitor of neuronal serotonin (5-HT) uptake but has no effect on the uptake of noradrenaline(NA) and dopamine (DA) and no antagonistic activity towards 5-HT, histamine, gamma aminobutyric acid (GABA) and acetylcholine. It is an extremely specific and potent inhibitor of neuronal 5-HT uptake. Uptake mechanisms for other transmitter amines are not influenced by the drug[1]. The SSRI citalopram has a greater effect on proliferation and a lesser effect on apoptotic activity. It affects cell cycle regulation by increasing proliferative potential and decreasing apoptotic activity in a site specific manner that may be indicative of hyperplasia. Citalopram alters FGF, MSX and TGFB expression in osteoblast cell culture[3].
Cell Research Cell lines MC3T3-E1 murine calvaria osteoprogenitor cells
Concentrations 0.1 nM-100 μM
Incubation Time 3 or 7 days
Method

Cells are cultured in alpha minimum Eagles medium supplemented with 1% penicillin/streptomycin, 10% fetal bovine serum and Amphotericin B. For control data, cells are cultured for 3 or 7 days with standard alpha proliferation media. For SSRI treatments, media is supplemented with citalopram eluted to serially diluted doses between 10−4 mol through 10−10 mol to achieve a dose response curve.
In Vivo
In vivo

Citalopram is devoid of cardiotoxic effects even when animals are exposed to concentrations far above the therapeutic level. In man citalopram is metabolized to compounds which are also potent 5-HT-uptake inhibitors without effect on noradrenaline(NA) uptake and which are found in lower concentrations than citalopram itself. Citalopram (1-16 mg/kg) stimulates the hind limb flexor reflex in the spinal rat. Citalopram potentiates 5-HT transmission~ possibly by producing very strong uptake inhibition without simultaneously blocking the post-synaptic 5-HT receptors[1].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
