|Description||JTC-801 is a selective opioid receptor-like1 (ORL1) receptor antagonist with IC50 of 94 nM, weakly inhibits receptors δ, κ, and μ.|
JTC-801 displays about 12.5-, 129-, and 1055-fold selectivity for ORL1 receptor (Ki = 8.2 nM) over μ-, κ-, and δ-opioid receptors, respectively. JTC-801 does not inhibit forskolin-stimulated cyclic AMP accumulation in human ORL1 receptor-expressing HeLa cells, but it prevents nociceptin-induced inhibition of cyclic AMP accumulation, indicating that JTC-801 possesses full antagonistic activity.  In rat cerebrocortical membrane, JTC-801 inhibits ORL1 receptor with IC50 of 472 nM and μ-receptor with IC50 of 1831 nM. JTC-801 completely antagonizes the suppression of nociceptin on forskolin-induced accumulation of cyclic AMP with IC50 of 2.58 μM in HeLa cells expressing ORL1 receptor. 
|In vivo||Oral administration of JTC-801 (0.3-3 mg/kg) antagonizes nociceptin-induced allodynia in mice, and shows analgesic effect in a hot plate test using mice and in a formalin test using rats.  In mouse hot-plate test, JTC-801 prolongs escape response latency (ERL) or exposed heat stimulus with minimum effective doses (MED) of 0.01 mg/kg by i.v. or 1 mg/kg by p.o. In the rat formalin test, JTC-801 reduces both the first and second phases of the nociceptive response with MED of 0.01 mg/kg71 by i.v. or 1 mg/kg by p.o.  JTC-801 dose-dependently normalizes paw withdrawal latency (PWL). Although JTC-801 does not inhibit a chronic constriction injury (CCI)-induced decrease in bone mineral content (BMC) and bone mineral density (BMD), it inhibits an increase in the number of osteoclasts.  Tactile allodynia induced by L5/L6 spinal nerve ligation is reversed by both systemic (3-30 mg/kg) and spinal (22.5 and 45 pg) JTC-801 in a dose-dependent manner. Furthermore, systemic JTC-801 reduces Fos-like immunoreactivity in the dorsal horn of the spinal cord (laminae I/II).  JTC-801 produces dose-dependent mechanical and cold anti-allodynic effects with ED50 of 0.83 mg/kg and 1.02 mg/kg, respectively. |

* 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.
