MK-4409
MK-4409 is an orally active and blood-brain barrier-penetrant fatty acid amide hydrolase (FAAH) inhibitor (human IC50 = 11 nM; rat IC50 = 11 nM) that reversibly and non-covalently inhibits this serine hydrolase, elevating endogenous fatty acid ethanolamides. MK-4409 alleviates inflammatory and neuropathic pain, with a long duration of action, and reduces edema. MK-4409 can be used for research on inflammatory and neuropathic pain.

Parmacokinetics
| Species | Dose | Route | T1/2 | CL | Vd | F |
|---|---|---|---|---|---|---|
| Rat[3] | 1 mg/kg | i.v. | 4.3 h | 20 mL/min/kg | 6.2 L/kg | 120 % |
In Vivo
MK-4409 (3 mg/kg; oral) alleviates neuropathic pain in the rat spinal nerve ligation (SNL) model, with a duration of action lasting up to 24 h[2].
MK-4409 (30 mg/kg; oral; single administration) demonstrated excellent efficacy in the rat CFA inflammatory pain model, reversing 70-71% of tactile allodynia at 30 mg/kg and maintaining efficacy for more than 10 days without tachyphylaxis[3].
MK-4409 (3-100 mg/kg) produced approximately 50% analgesic effects at doses of 3, 30, and 100 mg/kg in the rat SNL neuropathic pain model, and did not cause motor skill impairment at doses up to 100 mg/kg[3].

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.
