1 Customer Review
ADL-5859 respectively ADL-5747 were dopioid agonists (DORs) which were developed as analgesics for post-operative, neuropathic or musculoskeletal pain. They were expected to have superior analgesic potency over the existing ones, due to the different receptor targeted. However their development was stopped due to unconvincing efficacy.

|Description||ADL5859 HCl is a δ-opioid receptor agonist with Ki of 0.8 nM, selectivity against opioid receptor κ, μ, and weak inhibitory activity at the hERG channel. Phase 2.|
ADL5859 agonizes δ-opioid receptor with a 1000-fold selectivity than µ- or κ-opioid receptor with Ki of 32 nM and 37 nM, respectively.ADL5859 displays weak inhibitory activity at the hERG channel with an IC50 of 78 μM. The EC50 of ADL5859 against δ opioid receptor is 20 nM.
|In vivo||At the screening dose of 3 mg/kg p.o., ADL5859 produces 100% reversal of hyperalgesia in the inflamed paw. The oral ED50 of ADL5859 in the FCA mechanical hyperalgesia assay is 1.4 mg/kg. The antihyperalgesia produced by ADL5859 (3 mg/kg, p.o.) is reversed by pretreatment with the δ opioid antagonist naltrindole (0.3 mg/kg s.c.), thus demonstrating a δ receptor mediated effect.In the rat forced swim assay, ADL5859 (3 mg/kg p.o.) produces robust antidepressant-like activity, as evidenced by a significant decrease in the time spent immobile and a significant increase in the time spent swimming. The bioavailability of ADL5859 (3 mg/kg p.o.) in rats and dogs is 33% and 66%, respectively.ADL5859 efficiently reduces inflammatory and neuropathic pain mainly by recruiting δ-opioid receptors expressed by peripheral Nav1.8-expressing neurons.|

For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
