Org 27569 is a drug that is a used in biological studies for structure-activity relationships of indole-carboxamides as CB1 receptor allosteric modulators.

Potent CB 1 receptor allosteric modulator (pEC 50 = 8.24). Significantly increases binding of the CB 1 agonist [ 3 H]CP 55.940 (pK b = 5.67) and decreases binding of the CB 1 inverse agonist [ 3 H]SR 141716A (pK b = 5.95). Inhibits CB 1 receptor antagonist efficacy in vitro (pK b = 7.57).
