AM281 (0.01-10 μM) promotes a concentration dependent increase in 10 μM Aβ 25-35 induced neurotoxicity in SH-SY5Y cells in the presence of 10 μM KSO 1-6[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Chronic administration of AM281 at 2.5 mg/kg improves recognition index to the 22.1±4.8 and single dose of AM281 at 5 mg/kg improves the memory impairment to the 8.5±4, as compared with vehicle-treated which is 4.8±2.5. Administration of AM281 at a dose of 2.5 mg/kg in chronic form and 5 mg/kg in acute dose improve memory[3].

Animal Model:Male NMRI mice with the weight of 25-30 g[3]
-
Dosage:0.62, 1.25 and 2.5 mg/kg (chronic administration); 2.5, 5 and 10 mg/kg (acute administration)
-
Administration:Administrated i.p. every day concurrently with morphine except the day of experiment (chronic administration); Singly injected 40 min before second trial (acute administration)
-
Result:The simultaneous daily administration of AM281 with morphine significantly shortened the exploration time, as compared with morphine-dependent mice receiving vehicle.
Acute administration at a dose of 5 mg/kg, significantly augmented recognition index.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
