Jimscaline (C-(4,5,6-trimethoxyindan-1-yl)methanamine) is a conformationally-restricted derivative of the cactus-derived hallucinogen mescaline, which was reported in 2006 by a team at Purdue University led by David E. Nichols. It acts as a potent agonist for the 5-HT2A and 5-HT2C receptors with the more active (R)-enantiomer having a Ki of 69 nM at the human 5-HT2A receptor, and around three times the potency of mescaline in drug-substitution experiments in animals.[1] This discovery that the side chain of the phenethylamine hallucinogens could be constrained to give chiral ligands with increased activity then led to the later development of the super-potent benzocyclobutene derivative TCB-2.[2][3]
