although most of ligands tested displaced [ 3h ] 5-ht in a manner suggestive of a single site , displacement curves for ( +/- ) -8-hydroxy-dipropylaminotetralin ( 8-oh-dpat ) , 5-methoxytryptamine , 5-methyltryptamine and 5-methoxy-n , n-dimethyltryptamine displayed non-unity hill plots , suggesting multiple site interactions .
