We synthesized new N-phenylethyl-1H-indole-2-carboxamides as the first SAR study of allostericmodulators of the CB1receptor. The presence of the carboxamide functionality was required in order to obtain a stimulatory effect. The maximum stimulatory activity on CB1 was exerted by carboxamides 13 (EC50 = 50 nM) and 21 (EC50 = 90 nM) bearing a dimethylamino or piperidinyl group, respectively, at position
