In this study, a series of trans-4-(2-(1,2,4,5-tetrahydro-3H-benzo[d]azepin-3-yl)ethyl)cyclohexan-1-amine derivatives as potential antipsychotics were synthesized and biologically evaluated to discover potential antipsychotics with good drug target selectivity. The preliminary structure-activity relationship was discussed, and optimal compound 12a showed both nanomolar affinity for D2/D3/5-HT1A/5-HT2A receptors and weak α1 and H1 receptor binding affinity. In addition, 12a was metabolically stable in vitro, displayed micromolar affinity for the hERG channel, and exhibited antipsychotic efficacy in the animal model of locomotor-stimulating effects of phencyclidine.

A series of novel benzisothiazolylpiperazine derivatives combining potent dopamine D2and D3, and serotonin 5-HT1Aand 5-HT2Areceptor properties were synthesized and evaluated for their potential antipsychotic properties. The most-promising derivative was 9j. The unique pharmacological features of 9j were a high affinity for D2, D3, 5-HT1A, and 5-HT2Areceptors, together with a 20-fold selectivity for the D3versus D2subtype, and a low affinity for muscarinic M1(reducing the risk of anticholinergic side effects), and for hERG channels (reducing incidence of QT interval prolongation). In animal behavioral models, 9j inhibited the locomotor-stimulating effects of phencyclidine, blocked conditioned avoidance response, and improved the cognitive deficit in the novel object recognition tests in rats. 9j exhibited a low potential for catalepsy, consistent with results with risperidone. In addition, favorable brain penetration of 9j in rats was detected. These studies have demonstrated that 9j is a potential atypical antipsychotic candidate.

The superior activity of N (2 chloroethyl) N' (trans 4 methylcyclohexyl) N nitrosourea (MeCCNU) against advanced murine Lewis lung carcinoma in comparisons with the cis form and other nitrosoureas prompted the synthesis of a number of MeCCNU analogues, including several cis trans pairs. The methyl group was replaced by a variety of substituents (CO2H, CH2CO2H, CO2Me, CH2OAc, CH2Cl, OMe); the trans 3 methylcyclohexyl, cis 2 methyl 1,3 dithian 5 yl, cis and trans 2 methyl 1,3 dithian 5 yl tetraoxide, and 1 methylhexyl (open chain) analogues were also prepared. Preliminary tests against murine leukemia L1210 revealed therapeutic indices (ED50/LD10) ranging from 0.26 to 0.79; all but 3 analogues effected 50% cure rates at nontoxic doses, the open chain analogue being one of the least active. In terms of therapeutic index, diequatorial (trans 4) isomers were, with one exception, as active as or, in 4 of the 8 examples, somewhat more active than the corresponding axial equatorial (cis 4) isomers. In this series, 4 of the 5 2-fluoroethyl analogues prepared were clearly inferior to the corresponding 2 chloroethyl analogues.
