A1480LS
A1480LS is a peripherally restricted, orally active covalent and irreversible inhibitor of DAGLα and DAGLβ, with IC50 values of 6 nM and 4 nM against human targets, respectively, and IC50 values ≤15 nM across mouse, rat, dog, monkey and human systems. A1480LS reduces the levels of 2-arachidonoylglycerol, arachidonic acid, and cyclooxygenase- and lipoxygenase-derived eicosanoids. A1480LS inhibits injury-induced production of 2-arachidonoylglycerol and arachidonic acid in the peripheral sciatic nerve, and suppresses the responses of high-threshold and wide-dynamic-range-like dorsal horn neurons to mechanical stimulation. A1480LS alleviates pain behaviors in rat models of inflammatory pain, neuropathic pain and chemotherapy-induced peripheral neuropathy.

In Vivo
A1480LS (15, 20 mg/kg; p.o.) rapidly alleviates and continuously inhibits paclitaxel-induced mechanical hyperalgesia in rats during 5 consecutive days of administration. It also reverses and maintains CCI-induced mechanical allodynia in rats to the sham operation level, while restoring the injury-induced elevated levels of 2-AG and AA in the sciatic nerve to normal, without affecting the levels of these lipids in the brain[1].
A1480LS (1 mg/kg; i.v.) selectively inhibits the activity of HT and WDR-like dorsal horn neurons in anesthetized CCI rats without altering the activity of LTMRs, indicating that it suppresses spinal nociceptive sensory input[1].
A1480LS (8-30 mg/kg; p.o.) does not modulate PTZ-induced seizure susceptibility or brain 2-AG levels in rats, is well tolerated in rats, with only mild, transient reduction in abdominal muscle tone observed in some animals; these findings indicate that it poses no central nervous system epileptogenic risk[1].

Animal Model:Sprague Dawley (male, 176-206 g, intraplantar CFA injection)[1]
-
Dosage:1 mg/kg; 2.5 mg/kg; 5 mg/kg; 10 mg/kg; 20 mg/kg
-
Administration:p.o.; 2 doses (2 h before CFA, 24 h after CFA)
-
Result:Increased mechanical withdrawal thresholds dose-dependently 4 h after the second dose, with an ED50 of 7.7 mg/kg.
Achieved average blood concentrations of 1.1 μM (free plasma concentrations=1.5 nM) at 20 mg/kg, with an EC50 of 0.22 μM to suppress allodynia.
Inhibited kidney DAGLβ activity and reduced kidney 2-AG concentrations dose-dependently.
Caused partial brain DAGLα/β inhibition at 10 and 20 mg/kg without brain 2-AG depletion.
-
Animal Model:Sprague Dawley (male, intraperitoneal paclitaxel injection 1 mg/kg daily for 5 consecutive days)[1]

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.

Formalin-Induced Paw Inflammation/Nociceptive Inflammation
The formalin-induced paw inflammation/nociceptive test is a chemical persistent pain model in rodents in which subcutaneous injection of formalin into the hind paw produces spontaneous nocifensive behaviors such as flinching and licking. The response is classically biphasic, consisting of an early acute phase (Phase I) reflecting direct activation of peripheral nociceptors (particularly C-fiber afferents), followed by a later prolonged phase (Phase II) associated with central sensitization in the spinal dorsal horn driven by sustained afferent input and inflammatory signaling. This model is widely used to evaluate analgesic and anti-inflammatory interventions because it captures both peripheral nociception and central sensitization processes within a single assay system.
