Biological Activity
Neuronal nicotinic receptor[1]
Nelonicline is an agonist that binds with high affinity to α7 nAChRs in human brain (Ki= 12.3 nM) and activates currents in Xenopus oocytes expressing recombinant human α7 nAChRs (EC50=2 μM; intrinsic activity of 74% relative to acetylcholine). Nelonicline does bind to α3β4* nAChRs in human IMR-32 neuroblastoma cells (Ki=60 nM), but has only 12% efficacy at 100,000 nM in a calcium flux assay in these cell. Like some other α7 nAChR agonists, Nelonicline is also a 5-HT3 receptor antagonist, but it has >10-fold lower affinity for this receptor than for α7 nAChRs (Ki of 140 nM)[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1.25 mg/mL (3.99 mM); Clear solution
This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1.25 mg/mL (3.99 mM); Clear solution
This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Monkeys[1]
MPTP-lesioned monkeys are used. All monkeys have been administered MPTP and exhibited mild to moderate parkinsonism. All monkeys are orally gavaged with L-dopa/carbidopa twice daily, which lead to the development of stable abnormal involuntary movements or dyskinesias. The treatment groups are as follows: vehicle-treated (n=6), nicotine-treated (n=5), Nelonicline treated (set 1, n=5) and Nelonicline-treated (set 2, n=5). These latter two sets of monkeys have previously been given ABT-894 and ABT-107 but using somewhat different treatment regimens. The present study is done after a 7 wk washout period, when LIDs are similar in all groups. Nelonicline is administered orally in a small cracker 30 min before L-dopa (10 mg/kg) and carbidopa (2.5 mg/kg). Nicotine, a positive control, is provided in the drinking water. Nelonicline is tested at 0.03, 0.10, 0.30 and 1.0 mg/kg, with each dose of Nelonicline tested for 1 or 2 wk[1].
