Bilaid A1 is a tetrapeptide agonist of the μ-opioid receptor (Ki = 750 nM in HEK293 cell membranes expressing the human receptor) and a derivative of bilaid A .1 It inhibits forskolin-induced cAMP accumulation by 47% in HEK293 cells expressing the human μ-opioid receptor when used at a concentration of 10 μM.
