44およびその中の参照文献参照、に若干類似している。Although the psychotropic compounds listed above are generally related to the compounds of the present invention, they can be distinguished based on the B moiety of Structural Formula 1. In essence in the prior art compounds B is usually a monocyclic heteroaryl ring and the only examples of bicyclic systems are fused benzo ring heterocycles, ie benzisothiazole or benzisoxazole ring systems. These distinguish these compounds from the compounds of the invention in which B consists of different types of fused heterocycles, ie flow, pyrrolo, cyclopentadieno, or thienopyridine ring systems. The compounds are also pharmacologically distinguishable from prior art compounds on the basis of their psychotropic and side-effect profiles. In this regard, the compounds of the invention have selective antipsychotic (neuroleptic) activity with serotonin antagonism and, surprisingly, have a low affinity for dopamine receptors, which is described in the prior art antipsychotic ( In contrast to the above). In this regard, the compound is an atypical standard neuroleptic drug, clozapine (2), The Merck Index, 10th Edition (1983) p.3.

力を示した。 As can be seen, clozapine belongs to the dibenzodiazepine class of psychotropic drugs, which have few structural relationships with compounds of this series. Furthermore, the compound is unlikely to produce adverse extrapyramidal symptoms associated with chronic administration of currently used antipsychotics. Furthermore, compounds selected from this series have demonstrated the ability to reverse the catalepsy resulting from the administration of the standard neuroleptic drug, trifluoperazine, in animal models.

Certain compounds (commonly designated as ligands) have been identified that bind preferentially to specific high affinity sites in brain cells that address the potential for psychoactive or side effects. Inhibition of binding of radiolabeled ligands to such specific high affinity sites appears to be a measure of the ability of the compound to use for corresponding central nervous system function or cause side effects in vivo. This principle is used, for example, in tests such as measuring the inhibition of [ 3 H] spiperone binding, which shows marked dopamine receptor binding activity [Burt et al., Molecular Pharmacolog.

関連すると思われる。The data obtained from the above binding studies show that the compounds of the present invention have moderate to low affinity for dopaminergic receptors, but very high affinity for serotonin S 1 and S 2 sites. These binding properties distinguish the compounds of the present invention from the prior art compounds and most of the clinically useful antipsychotic agents currently in use. In this regard, the compound possesses some of the pharmacological properties similar to the atypical standard neuroleptics, clozapine, a dibenzodiazepine compound. The lack of dopaminergic binding affinity of the subject compounds appears to be associated with reduced propensity to develop unfavorable extrapyramidal side effects common to commonly used antipsychotics.

物学的データは表6(後記)に示される。According to the pharmacological profiles confirmed by these in vivo tests, these compounds of formula I show that they are relatively effective in the CAR test and have an oral ED 50 value of <100 mg / kg-body weight. , Has potential antipsychotic potential in that they effectively block apomorphine-induced stereotypy. This blockade of apomorphine-induced stereotypy represents dopamine antagonist activity and is accepted as a totally specific screen for neuroleptic activity. This group of compounds can be considered to have selective antipsychotic activity as long as the antipsychotic activity is observed at doses that do not cause catalepsy. Not only are these compounds relatively inactive in the formation of catalepsy, but more importantly, they reverse neuroleptic-induced catalepsy with ED 50 values <20 mg / kg given by the preferred compounds of the invention orally. Represents ability. The importance of the effects of these compounds of the present invention on catalepsy induction and reversal is even better understood when considering that antipsychotics are known to be the class that produce the extrapyramidal response. These unfavorable extrapyramidal reactions are serious therapeutic side effects and include acute torsion dystonia, akathisia, Parkinsonism and tardive dyskinesia. Some in vivo biological data are shown in Table 6 (below).
