1.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 20 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <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.

生物活性

製品説明 URB597 (KDS-4103) is a potent, orally bioavailable FAAH inhibitor with IC50 of 4.6 nM, with no activity on other cannabinoid-related targets. Phase 1.
in vitro URB597 binds in the hydrophobic pocket and catalytic core of FAAH that connects the active site residues to the membrane surface of FAAH. [1] URB597 inhibits FAAH activity in human liver microsomes with IC50 of 3 nM. [2] URB597 reduces the expression of the LPS-induced enzymes cyclo-oxygenase 2 (COX-2) and inducible nitric oxide synthase (iNOS; NOS2) in primary rat microglial cell, with a concomitant reduction in the release of the inflammatory mediators prostaglandin E2 (PGE2) and (NO) nitric oxide. [3] URB597 evokes Ca2+ entry in HEK293-F Cells transiently expressing human or rat TRPA1 gene. URB597 also activates Ca2+ entry in rat DRG neurons natively expressed TRPA1 channels. [4]
in vivo URB597 inhibits [3H]anandamide hydrolysis in rat brain membranes with a parallel increase in brain anandamide, OEA, and PEA content by inhibition of FAAH. URB597 enhances the hypothermia effect induced by ethanolamide by inhibiting FAAH. [5] When delivered intraperitonealy (0.3 mg/kg) URB597 reduces allodynia and hyperalgesia through cannabinoid CB1 and CB2 receptor-mediated analgesia in rats with inflammatory pain. [6] URB597 reduces the reduction in body weight gain and sucrose intake induced by the chronic mild stress in rats through inhibition of brain FAAH activity. [7] URB597 could reverse most depressive-like symptoms induced by adolescent THC exposure in femal rats. [8]

キナーゼアッセイ Pharmacology
Membrane fractions are prepared from brain homogenates, and FAAH activity is assayed using [3H]anandamide (anandamide[ethanolamine-3H], 60 Ci/mmol) as a substrate. Rat brain membranes (50 μg protein) are incubated for 30 min at 37 °C in buffer containing [3H]anandamide and varying concentrations of URB597. At the end of the incubation period, we stopp the reactions with a mixture of chloroform/methanol and measured [3H]ethanolamine in the aqueous phase by liquid scintillation counting.
動物実験 動物モデル Adult male Wistar rats (250–300 g) and C57/BL6 or FAAH-/- mice
投薬量 0.3 mg/kg
投与方法 Inject subcutaneously in a single dose 2 hours or 16 hours before killing
