CHO	EC₅₀	13 nM Compound: Cabergoline	Agonist activity at human 5-HT2B receptor transfected in CHO cell assessed as IP1 production incubated for 30 mins measured by HTRF detection method Agonist activity at human 5-HT2B receptor transfected in CHO cell assessed as IP1 production incubated for 30 mins measured by HTRF detection method	[PMID: 23606928]

In Vitro

Cabergoline acts as a potent agonist of D₂, D₃ and 5-HT_2B receptors. Pretreatment with Cabergoline inhibits H₂O₂-induced neuronal cell death in a dose-dependent manner. In the following experiments, 10 μM of Cabergoline is used to investigate its neuroprotective effects. MAP2 staining reveals that Cabergoline significantly suppresses the loss of neurons caused by H₂O₂ incubation. The detection of apoptotic nuclear condensation suggested that Cabergoline prevents apoptotic cell death following H₂O₂ exposure^[1].

In Vivo

The most significant reduction in rapid eye movement (REM) sleep bout number occurred during the light phase, in which Cabergoline-injected female handled mice has 67.3% less REM sleep bouts (F_(1,11)=12.892, P=0.004), although the greatest number in reduction of REM sleep bouts occurr during the dark phase (82.3% fewer REM sleep bouts; F_(1,11)=3.667, P=0.082). In male mice, Cabergoline reduces baseline Prolactin (PRL) levels (98.5%; F_(1,6)=13.192, P=0.011) from 5.8±1.3 to 0.08 ng/mL within 2 hours of injection. After a 7-day recovery period, PRL levels return to values that are not different from baseline (5.0±0.60 ng/mL; F_(1,6)=0.715, P=0.43)^[2].

Protocol

Cell Assay^[1]

Primary cortical neurons are prepared. Cabergoline (10 µM; except for experiments of dose-dependency) is applied to cortical cells at DIV 6-7. After 24-hour Cabergoline treatment (except for examination of pretreatment time-dependency of Cabergoline), H₂O₂ (50 µM; except for the dose-dependency of H₂O₂) is added. All inhibitors and antagonists, including spiperone, U0126, SB203580, SP600125, AP5, and nifedipine are applied 20 min before Cabergoline or H₂O₂ addition. L-glutamate is added at DIV 7-8 for cell death induction. Cell survival rate is measured by MTT assay. After the indicated treatment with drugs is completed, culture medium is replaced with 200 µL fresh medium containing 40 µl MTT solution (2.5 mg/mL, diluted in PBS) and cells are incubated at 37°C for 1.5-2.5 hours. Then, 200 µL lysis buffer containing isopropyl alcohol is applied to each well and mixed by pipetting. Each sample is moved to a 96-well plate and its absorbance at 570 nm is measured using an iMark Micro plate leader. Cell survival rate is quantitated by absorbance measurement, because MTT (yellow) is deoxidized to formazan (violet) in proportion to mitochondrial activity^[1].

Animal Administration^[2]

Mice^[2]
Female and male C57BL/6J mice are used.Cabergoline is dissolved in 100% pharmasolve and then diluted with 20% β-cyclodextrin in water to yield a final concentration of 0.15-0.5 mg/mL Cabergoline. Mice received a 0.3-mg/kg ip injection of Cabergoline or vehicle. All drugs are prepared within 48 hours of experiment and stored at 4°C. Solutions are allowed to reach at room temperature before injection.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
