KT109 is a potent and selective inhibitor of?DAGLβ. | [Biochem/physiol Actions]
KT109 is a potent and selective inhibitor of Diacylglycerol lipase DAGLβ. Diacylglycerol lipases DAGLα and DAGLβ are serine hydrolases that biosynthesize the endocannabinoid 2-arachidonoylglycerol (2-AG). A lack of selective inhibitors has hampered study of these lipases. KT109 is a potent and selective DAGLβ inhibitor with an IC50 of 42 nM, ~60-fold selectivity for DAGLβ over DAGLα, and negligible activity against FAAH, MGLL and ABHD11, other key enzymes involved in endocannabinoid signaling. KT109 shows some inhibitory activity against PLA2G7 (IC50 = 1 μM) but no inhibitory activity against cytosolic phospholipase A2 (cPLA2 or PLA2G4A). The main off target inhibition against ABHD6 (IC50 = 16 nM) can be controlled for by use of the related compound, KT195, a potent (IC50 = 10 nM) and selective ABHD6 inhibitor with negligible activity against DAGLβ. KT109 disrupts the lipid network involved in macrophage inflammatory responses, lowering 2-AG, as well as arachidonic acid and eicosanoids, in mouse peritoneal macrophages. | [in vivo]
KT109 (0.1-10 mg/kg; i.p.; 4 h) inhibits DAGLβ in mice with good potency and selectivity, exhibiting cross-reactivity with only a handful of additional serine hydrolases in macrophages[1].
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. |
