KT109
Based on 1 publication(s) in Google Scholar
KT109 is a potent and an isoform-selective inhibitor of diacylglycerol lipase-β (DAGLβ) with an IC50 of 42 nM. KT109 has ~60-fold selectivity for DAGLβ over DAGLα. KT109 shows inhibitory activity against PLA2G7 (IC50=1 µM). KT109 shows negligible activity against FAAH, MGLL, ABHD11, and cytosolic phospholipase A2 (cPLA2 or PLA2G4A). KT109 perturbs a lipid network involved in macrophage inflammatory responses and lowers 2-Arachidonoylglycerol (HY-W011051), Arachidonic acid (HY-109590) and eicosanoids in mouse peritoneal macrophages.

KT109 (0.1-100 nM in Neuro 2A, 0.001-10 μM in PC3; 4 h) inactivates DAGLβ in Neuro2A and PC3 cells with IC50 values of 14 nM and 0.58 μM, respectively[1].
KT109 (50 nM in Neuro 2A, 100 nM in PC3, 4 h) shows a marked reduction in cellular 2-AG (~90%), and arachidonic acid (AA), and increases SAG in Neuro2A and PC3 cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
KT109 (5 mg/kg; i.p.; 4 h) lowers 2-AG, as well as Arachidonic acid (HY-109590) and eicosanoids, in mice peritoneal macrophages. KT109 reduces secreted TNF-α levels in lipopolysaccharide-stimulated macrophages[1].
KT109 (1.6-40 mg/kg; i.p.) reverses the allodynic responses of Lipopolysaccharides (HY-D1056) (LPS)-treated paw, but i.c.v. or i.t. administration of KT109 do not alter LPS-induced allodynia in C57BL/6J mice[2].
Repeated KT109 (40 mg/kg; i.p.; once daily for 6 days) administration prevents the expression of LPS-induced allodynia, without evidence of tolerance in C57BL/6J mice[2].
KT109 reverses allodynia in the chronic constrictive injury (CCI) (40 mg/kg) and chemotherapy-induced neuropathic pain (CINP) (1.6-40 mg/kg) models and lacks discernible side effects in C57BL/6J mice[2].

Animal Model:DAGL-β (-/-) and (+/+) on C57BL/6J mice (23-40 g) (injected with 2.5 μg LPS into the plantar surface of the right hind paw after the 5th dose.)[2]
-
Dosage:40 mg/kg
-
Administration:Intraperitoneal injection (i.p.). once daily for 6 days
-
Result:Repeated administration prevented the expression of LPS-induced allodynia, without evidence of tolerance.
-
Animal Model:Daglb+/+, Daglb+/- and Daglb-/- mice on C57BI/6 and 129/SvEv mixture background were first treated intraperitoneally (i.p.) with 4% (w/v) thioglycollate 4 d before to induce recruitment of macrophages to the peritoneal cavity[1]
-
Dosage:0.1, 0.5, 1, 5, 10 mg/kg
-
Administration:Intraperitoneal injection (i.p.). 4 h
-
Result:Completely inactivated DAGLβ at doses as low as 0.5 mg/kg body weight. Also inhibited ABHD6.
Time-course studies revealed that produced complete inhibition of macrophage DAGLβ by 1 h after in vivo treatment, and this inhibition was maintained for > 16 h.

Animal Model:Pla2g4a+/+ and Pla2g4a-/- mice on a BALB/c background and Daglb+/+, Daglb+/- and Daglb-/- mice on C57BI/6 and 129/SvEv mixture background were first treated intraperitoneally (i.p.) with 4% (w/v) thioglycollate 4 d before to induce recruitment of macrophages to the peritoneal cavity[1]
-
Dosage:5 mg/kg
-
Administration:Intraperitoneal injection (i.p.). 4 h
-
Result:Marked decreases in 2-AG content in macrophages.
Significant increases in the DAGLβ substrate SAG, and reductions in arachidonic acid and in the arachidonic acid-derived prostaglandins PGE2 and PGD2.
Significantly reduced secreted TNF-α levels in lipopolysaccharide-stimulated macrophages, and this suppressive effect was also observed in macrophages from Daglb−/− mice.
-
Animal Model:DAGL-β (-/-) and (+/+) on C57BL/6J mice (23-40 g)[2]
-
Dosage:1.6, 2.5, 5, 20, 40 mg/kg
-
Administration:Intraperitoneal injection (i.p.).
-
Result:Reversed LPS-induced allodynia in wild-type mice in a dose-dependent manner, but does not further alter the anti-allodynic phenotype in DAGL-β (-/-) mice.
