Chemical structures of TDIQ, and conformationally constrained forms of amphetamine (AMPH-CR), methamphetamine (METH-CR), and the hallucinogens DOM (DOM-CR) and DOB (DOB-CR). [...] Conformationally constrained analogs of the hallucinogens DOM and DOB (i.e., DOM-CR and DOB-CR) were not recognized by rats trained to discriminate 1.0 mg/kg of DOM from saline vehicle, but substituted in rats trained to discriminate TDIQ from vehicle (ED50 = 4.2 and 3.4 mg/kg, respectively) [15]. Interestingly, the TDIQ stimulus did not generalize to the N-methyl analog of DOM-CR [15]. Taken together with the findings obtained for METH-CR, it would appear that N-methylation is not tolerated with regard to producing TDIQ-like discriminative stimulus effects [15]. But, more importantly, and to reiterate what was stated above, it should not be assumed that "inactive" conformationally constrained rotamers are necessarily pharmacologically inactive; results depend on the similarity in the stimulus properties of the training drug and test agent.

"1,2,3,4-Tetrahydroisoquinoline analogs of phenylalkylamine stimulants and hallucinogens".Medicinal Chemistry Research.6 (6):400–411.Conformationally constrained, 1,2,3,4-tetrahydroisoquinoline (TIQ) analogs of central stimulant (e.g. amphetamine) and hallucinogenic (e.g. DOM) phenylalkylamines were prepared and evaluated to determine the contribution to activity of this conformational restriction. The amphetamine-related TIQs failed to produce locomotor stimulation in mice and did not produce amphetamine-appropriate responding in tests of stimulus generalization in (+)amphetamine-trained rats. Hallucinogen-related TIQs lacked appreciable affinity for 5-HT2A serotonin receptors and did not produce DOM-like effects in tests of stimulus generalization in DOM-trained rats. It is concluded that the phenylalkylamine conformation represented by the TIQs is not a major contributor to these actions.
