|Description||JNJ-1661010 is a potent and selective FAAH inhibitor with IC50 of 10 nM (rat) and 12 nM (human), exhibits >100-fold selectivity for FAAH-1 when compared to FAAH-2.|
FAAH preincubated with JNJ-1661010 suggests a slow reversibility of the interaction between the JNJ-1661010 and the active site, which is accelerated at higher temperatures.  JNJ-1661010 is a covalent, mechanism-based substrate inhibitor as examined by LC-ESI-MS. JNJ-1661010 docks with the phenylthiadiazole in the hydrophobic tunnel and the phenylurea in the hydrophilic pocket of FAAH. 
|In vivo||JNJ-1661010 (20 mg/kg i.p.) inhibits FAAH by at least 85% for up to 4 h after dosing, resulting accumulation of lipid ethanolamides in rat brain. JNJ-1661010 dose-dependently reverses the tactile allodynia with a maximum efficacy of approximately 90% at 30 min postdose in both Mild Thermal Injury (MTI) mice and rat model. JNJ-1661010 (20 mg/kg) reverses tactile allodynia by 60.8% at 30 min in rat spinal nerve ligation injury model. JNJ-1661010 (50 mg/kg i.p.) shows a significant attenuation of the hyperalgesia at 30 min postdose in rat carrageenan model of inflammatory pain.  Rats dosed with JNJ-1661010 (20 mg/kg i.p.) has a plasma Cmax of 26.9 μM at the Tmax of 0.75 h and a Cmax in the brain of 6.04 μM at the Tmax of 2 h. JNJ-1661010 (20 mg/kg i.p.) inhibits brain FAAH and elevates AEA level in brain tissue in rat. |

* 1 mg/ml means slightly soluble or insoluble.
* 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.
