[more ▼] The title compound, C19H16N2O, is a Reissert compound. The heterocyclic fragment of the molecule exhibits a 1,3-diplanar conformation. The phenyl ring is connected to the isoquinoline ring system via an amide bond that adopts an anti conformation with respect to the adjacent C-N bond in the adjacent heterocyclic ring. Intra-and intermolecular C-H center dot center dot center dot O hydrogen bonds are present in the crystal structure.

[more ▼] The crystal structure of cyproterone (systematic name: 6-chloro-1,2-dihydro-17-hydroxy-30H-cyclopropa[a]pregna-1,4,6- triene-3,20-dione), C22H27ClO3, is compared with cyproterone acetate, a potent anti-androgen steroid. The two compounds adopt a similar conformation, except for the cyclopropyl ring attached to the cyclohexenone ring (ring A). Cyproterone further adopts a crystal packing distinct from that of the acetate form. These differences result from hydrogen bonding between the free hydroxy group and the carbonyl group of ring A.

[more ▼] The crystal structure of the title compound, C17H17ClN4O, has been undertaken as part of our studies of dopamine receptors. The oxazepine ring has a boat conformation, while the piperazine ring is in a normal chair conformation. The dihedral angle between the two aromatic rings that lie on the same side of the oxazepine moiety is 113.99 (7)degrees. There is no hydrogen bonding.

[more ▼] The conformation of the title compound, C18H21N5, is very similar to that observed in other diaryldiazepine structures such as clozapine and clozapine dihydrobromide. N-H...H hydrogen-bond interactions result in the formation of a dimer.

[more ▼] The crystal structure determination of the title compound, C17H20ClN5, has been undertaken as part of studies on antipsychotic drugs. Its structure is compared with that of clozapine (C18H19ClN4), a well known atypical antipsychotic drug. The side chain is more flexible than in the N-methylpiperazine analogues, but its folding is influenced by an intramolecular N-H . . .N hydrogen bond. The distances between the N-distal atom, a possible pharmacophore, and the centres of the two aromatic rings are significantly shorter than in clozapine. The crystal packing involves one N-H . . .N intermolecular hydrogen bond. The title compound showed no affinity for the receptors tested. [less ▲] Detailed reference viewed: 25 (0 ULg) |
