Spinamide has a poor affinity for the dopamine D1 site (Ki=2530 nM), but it maintains affinity for the 5-HT1A site (Ki=50 nM) and binds to the dopamine D2 site (Ki=3 nM) [1].

| ln Vivo |
In monkeys following a fixed interval (FI) stimulus termination regimen, AMI-193 (0.003-0.01 mg/kg; im) dose-dependently lowers response rates [2]. In drug discrimination studies, the discriminative stimulus effect of cocaine is attenuated by AMI-193 (0.003-0.01 mg/kg; im) [2]. When administered intramuscularly, AMI-193 (0.003-0.01 mg/kg) lowers the rate of remission when combined with an intravenous cocaine regimen (0.1 mg/infusion) [2].

| Animal Protocol |
Animal/Disease Models: Adult male squirrel monkey (850-1300 g) [2]
Doses: 0.003, 0.01 mg/kg Route of Administration: intramuscularinjection on Tuesday, Wednesday and Thursday next week Experimental Results: diminished response rate. Cocaine reversed the heart-rate-lowering effects. |

| Additional Infomation |
Spinorphin is an azaspirocyclic compound composed of 1,3,8-triazaspiro[4.5]decane-4-one, with a phenyl group at the N-1 position and a 3-(4-fluorophenoxy)propyl group at the N-8 position. It is a selective 5-HT receptor antagonist, binding effectively to 5-HT2 receptors like spiroperon, but with lower affinity for 5-HT2C receptors. It is also a high-affinity D2 receptor antagonist (Ki = 3 nM). Unlike spiroperon, Spinorphin does not interfere with animal behavior. It functions as both a dopaminergic and serotonergic antagonist. It is an azaspirocyclic compound, an organofluorine compound, an aromatic ether, a tertiary amine compound, and a piperidine compound. Spinorphin has been reported to be found in Spiraea japonica, and relevant data exist.

| Solubility (In Vitro) |
DMSO : ~20 mg/mL (~52.16 mM)

|---|---|
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2 mg/mL (5.22 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 2 mg/mL (5.22 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

| 10 mM | 0.2608 mL | 1.3039 mL | 2.6078 mL |
*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
