Analgesic agent-4

Analgesic agent-4 is an adenosine A₃AR ligand with analgesic/antinociceptive activity. Analgesic agent-4 inhibits writhing responses in mice and exhibits dose-dependent activity in the acetic acid (HY-Y0319)-induced mouse writhing model. Analgesic agent-4 can be used in the research of pain-related diseases.

Description

All Adenosine Receptor Isoforms :

In Vitro

Analgesic agent‑4 (Compound 37) can bind to the human adenosine A₃ receptor, and this binding relies on conserved and enhanced hydrophobic interactions^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Analgesic agent-4 (3-300 mg/kg; subcutaneous injection; single administration) exhibits analgesic activity in the mouse writhing model induced by Acetic acid (HY-Y0319)^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
