GPR55 (EC50 = 250 nM)
|
---|---|
ln Vitro |
Activation of GPR55 significantly increased proliferation rates of hNSCs in vitro. These effects were attenuated by ML193, a selective GPR55 antagonist. ML184 significantly promoted neuronal differentiation in vitro while ML193 reduced differentiation rates as compared to vehicle treatment. Continuous administration of O-1602 into the hippocampus via a cannula connected to an osmotic pump resulted in increased Ki67+ cells within the dentate gyrus. O-1602 increased immature neuron generation, as assessed by DCX+ and BrdU+ cells, as compared to vehicle-treated animals. GPR55-/- animals displayed reduced rates of proliferation and neurogenesis within the hippocampus while O-1602 had no effect as compared to vehicle controls.[2]

Chemical Library Screening[1]
A β-arrestin (see methods below), high-throughput, high-content screen (HCS) of 300,000 compounds was used here to identify potent GPR55 selective antagonists. This work was performed in collaboration with the Molecular Libraries Probe Production Centers Network program. For more details about this library of compounds, see http://mli.nih.gov/mli/compound-repository/mlsmr-compounds/. Compounds were screened for antagonism (PubChem AID 2026) at GPR55 (using LPI as the agonist), as well as for both agonism and antagonism at GPR35 (PubChem AIDs 2809, 2815), CB1 (PubChem AIDs 2814, 2835) and CB2 (PubChem AIDs 2822, 2836). A cell line permanently expressing a β-arrestin GFP biosensor and an enhanced receptor of interest (i.e., GPR55, GPR35, CB1 or CB2) were employed in the high content imaging assay. Assay protocol descriptions (according to AID number) are accessible at the PubChem website (http://pubchem.ncbi.nlm.nih.gov/). Potent GPR55 antagonist compounds that lacked agonism or antagonism at GPR35, CB1 or CB2, were further evaluated for inhibition of pERK activation and PKCβII translocation produced by the GPR55 agonists, LPI or ML186 (see methods below). A set of novel GPR55 antagonist molecular scaffolds were selected from the screen ML191 (CID23612552), ML192 (CID1434953) and M193(CID1261822), and the binding of each compound was explored using a computer model of the GPR55 inactive state. |
Cell Assay |
To investigate the effects of GPR55 activation on hNSC proliferation, cells were plated on laminin‐coated 6‐well plates. Cells were allowed to adhere overnight and then treated with LPI (1 μM), the endogenous ligand for GPR55, or synthetic agonists, O‐1602 (1 μM) or ML184 (1 μM), in a reduced growth factor media (5% growth factor). Reduced growth factor medium was utilized to better mimic a less proliferative phenotype while still maintaining a ‘stemness’ state. Analysis by flow cytometry showed no significant reduction of nestin+ or Sox2+ populations after 48 h (data not shown). Cells treated with the selective GPR55 antagonist ML193 (5 μM) were pretreated for 30 min prior to addition of agonist. Vehicle‐treated cells received 0.1% DMSO in 5% growth factor media. For differentiation studies, cells were treated with either vehicle, ML184 (1 μM), ML193 (5 μM), or a combination of ML184 (1 μM) and ML193 (5 μM) in ReNcell medium that did not contain growth factors.[2]

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
