S-777,469 is a drug developed by Shionogi which is a cannabinoid receptor agonist, with 128x selectivity for the CB₂ subtype, having a CB₂ affinity of 36nM, and a CB₁ affinity over 4600nM.

In animal studies it showed antipruritic effects, and passed Phase II human trials for the treatment of atopic dermatitis, but development was ultimately not continued further.^[1]^[2]^[3]^[4]
