Abstract:

A series of new 5H-pyridobenzazepine and pyridobenzothiepine derivatives was synthesized by Pd-catalyzed formation of C-N and C-S bonds. All synthesized compounds were tested for their in vitro antimicrobial activity. The 5H-pyridobenzazepine derivatives showed better antibacterial and antifungal activity than corresponding 5H-dipyridoazepine analogs. Among the synthesized azepines, derivative 8 displayed potent activity against tested bacteria (MIC = 39-78 ?g/mL), while azepine 12 showed promising antifungal activity (MIC = 156-313 ?g/mL). The synthesized thiepine derivatives exhibited weak antibacterial activity, but showed pronounced antifungal activity.

Abstract:

The homologous series of three-atom bridged biaryls comprising 5,7-dihydro-1,2,3,9,10,11-hexamethoxydibenzo[c,e]oxepine, 6,7-dihydro-1,2,3,9,10,11-hexamethoxy-6-methyl-5H-dibenzo[c,e]azepinium chloride, 5,7-dihydro-1,2,3,9,10,11-hexamethoxydibenzo[c,e]thiepine, and the 6-oxide and 6,6-dioxide derivatives of the latter have been characterized by X-ray crystal structure analysis. Within this series the endocyclic and exocyclic biaryl dihedral angles vary over 10° ranges, reflecting the changing balance of intramolecular (steric, geometric) and intermolecular (crystal packing) forces, the former being potential control elements for fine-tuning the helicity of the biaryl system.

Abstract:

The validity of a new dopamine D-2 receptor interaction model based on conformational analysis and least-squares superimposition studies of the indan derivative tefludazine and the thiepin derivative octoclothepin was further tested by comparison of the effect of aromatic substitution on D-2 antagonistic activity in two series of indan and thiepin derivatives. The indan series include new derivatives substituted in the 4-, 7-, 2’- and 3’-position. The substitution effects were largely parallel with one important exception: Only 6-substituted indans have significant neuroleptic activity while both 8- and 7-substituted thiepin derivatives have neuroleptic activity. In indans additional fluorination in the 2’- or 4’-position is demanded to give potent neuroleptic activity, while a 3’-fluoro-substituted derivative was inactive. Fluorination is not necessary in thiepins although 3-fluoro derivatives have a significant prolonged duration of action. Considering the differences in physico-chemical properties, metabolism and pharmacokinetics between the two series, the largely parallel substitution effects support the new D-2 receptor model.

Abstract:

Reaction of nitrile IVa with the Grignard’s reagent 1-methyl-4-piperidylmagnesium chloride gave carbinol XIb as product. Carbinols XIa and XIb were dehydrated and hydrolysed with dilute hydrochloric acid to give hydrochlorides of the tricyclic amino acids Vb and Vc. Isomeric compounds with a carboxyl group in position 9 of the tricyclic skeleton were obtained either by hydrolysis of the formely prepared nitrile VIIb (compound VIIIb) or on reaction of bromoketone VIa with 1-methyl-4-piperidylmagnesium chloride, nucleophilic substitution of the bromine atom by the cyano group at the stage of carbinol XIIIb, and subsequent dehydration and hydrolysis of the cyano group, to give amino acid VIIIc. In the first case the synthesis of thiophene analogues XVIIIb and XVIIIc started from ketone XVa, which was brominated with bromine in acetic acid into position 2 of the tricyclic skeleton, followed by Grignard’s reaction with 3-dimethylaminopropylmagnesium chloride in tetrahydrofuran and hydrolysis to bromo derivative XVIb. In the second case derivative XVIc was obtained directly by bromination of hydrochloride XVc. Basic bromo derivatives XVIb and XVIc were reacted with butyllithium in tetrahydrofuran at –60°C to afford corresponding organometallic reagents which, when reacted with solid carbon dioxide, afforded the required amino acids XVIIIb and XVIIIc. Further, some other tricyclic nitriles were synthesized as potential intermediates. The prepared tricyclic amino acids Vb, Vc, VIIIb, VIIIc, XVIIIb and XVIIIc were tested both on animals and in assays of biochemical pharmacology. Some of them displayed considerable antihistaminic activity. The most interesting compound of this series, hydrochloride Vc (VUFB-17689) is a strong antihistaminic with distinctly suppressed sedative effects and it was therefore selected for a more detailed pharmacological testing.

Abstract:

The acid VI, prepared by reaction of potassium salts of (2-iodo-5-methoxyphenyl)acetic acid and 4-(methylthio)thiophenol in the presence of copper, was transformed via intermediates VII-IX to 2-methoxy-8-methylthio-10-piperazino-10,11-dihydrodibenzo[b,f]thiepins X and XI. Their demethylation with boron tribromide afforded 2-hydroxy derivatives of the neuroleptic agents methiothepin and oxyprothepin I and II. 11-Chloro-7-methoxy-2-methylthio-10,11-dihydrodibenzo[b,f]thiepin was subjected to substitution reactions with 1-methylpiperazine and 1-(ethoxycarbonyl)piperazine and gave piperazine derivatives XIII and XIV, out of which the latter gave the secondary amine XV by alkaline hydrolysis. The ethers XIII and XV were also cleaved with boron tribromide and gave 3-hydroxy derivatives of methiothepin (III) and its demethyl derivative IV. The phenols I, II, and IV are potential metabolites of the mentioned neuroleptic agents; compound III, which already was identified as a metabolite, disclosed properties of a strong and cataleptic neuroleptic agent with prolonged duration of the effects. The methoxy compounds X, XI, and XIII are practically devoid of the neuroleptic activity.

Abstract:

Reactions of N-(6,11-dihydrodibenzo[b,e]thiepin-11-yl)chloroacetamide (II) with dimethylamine, morpholine, and 2-(1-piperazinyl)ethanol afforded the amino amides III-V. Substitution reactions of 11-chloro-6,11-dihydrodibenzo[b,e]thiepin with ethylenediamine and N,N-dimethylethylenediamine gave the diamines VI and VII. 6,11-Dihydrodibenzo[b,e]thiepin-11-amine (I) was treated with ethyl chloroacetate and ethyl 2-bromopropionate to give the amino esters X and XI which were transformed on the one hand to the acids VIII and IX, and to the amides XII and XIII on the other. (6,11-Dihydrodibenzo[b,e]thiepin -11-yl)methylamine (XVIa) and (10,11-dihydro-5H-dibenzo[a,d]cycloheptene-5-yl)methylamine (XVIb) were transformed via the chloroacetamides XVIIa and XVIIb to the (4-methyl-1-piperazinyl)acetamides XVa and XVb. Compound V showed local anaesthetic and antiarrhythmic activity, the diamine VII had antihistamine and antireserpine effects, the amide XII was found to be an anticonvulsant, and the piperazines XVa and XVb inhibited effectively the formation of the indomethacin-induced gastric ulcers in rats.

Abstract:

Reinvestigation of the minor product of reaction of 6,11-dihydrodibenzo[b,e]thiepin-11-carbonitrile (I) with 1,2-dibromoethane in the presence of tetrabutylammonium bromide or benzyltriethylammonium chloride and 50% sodium hydroxide by means of 1H and 13C NMR spectroscopy led to the formula XI named in the title, which was confirmed by X-ray crystallographic analysis. The product of a similar reaction, carried out in dimethyl sulfoxide in the presence of potassium carbonate at 100 °C was identified as the stereoisomeric mixture of 11,11'-ethylenebis(6,11-dihydrodibenzo[b,e]thiepin-11-carbonitriles) (XII) which was separated to the components by preparative HPLC. The title compound XI was oxidized to the sulfoxide XIII and the sulfone XIV, and was transformed by reduction and the following methylation to amines XV and XVI. The reduction of the vinyl nitrile III with lithium aluminium hydride is complicated on the one hand by allylic rearrangement, and with cyanide anion abstraction on the other, the products being (E,Z)-mixture of 3-(6,11-dihydrodibenzo[b,e]thiepin-11-ylidene)propylamines (XVII) and 11-vinyl-6,11-dihydrodibenzo[b,e]thiepin (X).

Abstract:

The isofloxythepin (I) metabolite IV was synthesized via the acids IX and XI and the esters X and XII. The enamine VIII was prepared from 3-fluoro-8-(2-propyl)dibenzo[b,f]thiepin-10(11H)-one by two methods and was reduced to I. Cloflumide (II) was obtained by reaction of 2,10-dichloro-7-fluoro-10,11-dihydrodibenzo[b,f]thiepin with 3-(1-piperazinyl)propionamide and was oxidized to the sulfoxide XVI. The unsaturated analogue XVII of clopithepin (III) was prepared from 2-chlorodibenzo[b,f]thiepin-10(11H)-one by reaction with 2-bromoethanol in the presence of 4-toluenesulfonic acid in boiling benzene and by the following substitution reaction with 2-(1-piperazinyl)ethanol. An improved synthesis of 6-methyldibenzo[b,f]thiepin-10(11H)-one (XIX) was elaborated. The acid XXVII was synthesized and cyclized with polyphosphate ester. A mixture of compounds was formed from which the ketone XXXVI was isolated and processed by reaction with formamide and formic acid at 200 °C. One of the products was characterized as the formamide XXXIII and was reduced with lithium aluminium hydride to a basic product supposed to be XXXIV. A series of by-products was isolated and characterized. The enamine VIII (V⁄FB-17 156) was found to be a strong neuroleptic agent, similar to isofloxythepin (I). The enol ether XVII (V⁄FB-17 733) was characterized as a mild, practically noncataleptic neuroleptic agent.

Abstract:

The alcohol XIa, obtained by reaction of dibenzo[b,e]thiepin-11(6H)-one with vinylmagnesium bromide, was transformed by treatment with hydrogen bromide in acetic acid to the bromo compound XIIa which was converted via the nitrile XIIIa to the title acid VIIIa. The pure (E)-isomer was prepared and correlated via the dimethylamide XVIIIa with (E)-prothiadene (Ia). Similar procedures in the 2-methyl-6,11-dihydrodibenzo[b,e]thiepin and 10,11-dihydrodibenzo[a,d]cycloheptene series afforded the acids VIIIb and IV. The acids VIIIab were oxidized with hydrogen peroxide to the sulfoxides IXab and to the sulfones Xab. The acid IV is the suggested metabolite of the antidepressant amitriptyline (II) and the acids VIIIab-Xab are potential metabolites of the antidepressant prothiadene (Ia) and the antihistamine agent methiadene (Ib). The amides VII and XVIab were prepared from the acids via the acid chlorides. The (Z)-isomer of prothiadene (XXII) was prepared from dibenzo[b,e]thiepin-11(6H)-one by the Wittig reaction. The acids IV, VIIIab and IXab showed some antiinflammatory activity.

Thioxanthone, 10,11-dihydrodibenzo[a,d]cyclohepten-5-one, dibenzo[b,e]thiepin-11(6H)-one, its 2-methyl derivative, and thieno[2,3-c]-2-benzothiepin-4(9H)-one were reacted with 4-tetrahydrothiopyranylmagnesium bromide and the obtained tertiary alcohols IVabc, VIc, and XIX were dehydrated to the olefinic sulfides IXabc, Xc, and XXI. Addition of methyl iodide afforded the title compounds XIabc, XIIc, and XXII. The Grignard reactions were accompanied by the 1,6-addition giving the ketones XVI-XVIII as by-products. The reductive properties of tetrahydrothiopyranylmagnesium bromide were most striking in the case of reaction with 2-chlorothioxanthone; the isolation of thioxanthene and thioxanthone showed that nuclear dehalogenation took also place. Reactions of 11-chloro-6,11-dihydrodibenzo[b,e]thiepin and benzhydryl chloride with tetrahydrothiopyran-4-ol gave the sulfides XXV and XXVIII; whereas the latter reacted with methyl iodide under the formation of sulfonium salt XXIX, the former was cleaved and gave 4-hydroxyl-1-methyltetrahydrothiopyranium iodide (XXVI). The sulfonium salts are free of the central effects but their antihistamine activity is rather low.

Abstract:

2-Chloro-10,11-dihydrodibenzo[b,f]thiepin-10-thiol (VII) was synthesized from 2,10-dichloro-10,11-dihydrodibenzo[b,f]thiepin (IV) and was alkylated with a series of aminoalkyl chlorides which led to amino sulfides IX, XII, XIII, and XVI-XX. The primary amine IXa was transformed by treatment with ethyl chloroformate to the carbamate Xa which was reduced to the methylamino compound XIa. The carbamate XX was similarly reduced to compound XXI. Alkylation of VII with 2-bromoethanol gave the alcohol XIVa which was transformed to the crude tosylate XVa. Its reactions with the corresponding piperazines gave compounds XXII to XXIV. The alcohol XXII was esterified to the decanoate XXV. Reactions of the sodium salt of VII with ethyl chloroacetate, ethyl 2-chloropropionate and ethyl 4-chlorobutyrate gave the corresponding esters which were saponified to acids XXVIb-XXVIIIb. Their amides XXVId to XXVIIId and XXVIe were prepared either via the acid chlorides or via the esters. Out of the compounds prepared only XIa showed a clear profile of a potential antidepressant. The other compounds showed indications of thymoleptic, antiinflammatory and antimicrobial activities.

Abstract:

The epidermal growth factor receptors (EGFRs), in which overexpression (known as upregulation) or overactivity have been associated with a number of cancers, has become an attractive molecular target for the treatment of selective cancers. We report here the design and synthesis of a novel series of 4,5-dihydro-1H-thieno [2′,3′:2,3]thiepino[4,5-c]pyrazole-3-carboxamide derivatives and the screening for their inhibitory activity on the EGFR high-expressing human A549 cell line using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). A Docking simulation was performed to fit compound 6g and gifitinib into the EGFR to determine the probable binding models, and the binding sites and modes conformation of 6g and gifitinib were exactly similar, the two compounds were stabilized by hydrogen bond interactions with MET769. Combining with the biological activity evaluation, compound 6g demonstrated the most potent inhibitory activity (IC50 = 9.68 ± 1.95 μmol·L–1 for A549). Conclusively, 4,5-dihydro-1H-thieno[2′,3′:2,3]thiepino[4,5-c]pyrazole-3-carboxamide derivatives as the EGFR tyrosine kinase inhibitors were discovered, and could be used as potential lead compounds against cancer cells.

Abstract:

Reaction of 5,7-dihydrodibenzo[c,e]thiepin (I) with n-butyllithium resulted in the partial sulfur extrusion and in the formation of the 9,10-dihydrophenanthrene-9-thiolate anion (B). Its further transformations (by hydrolysis, aminoalkylation and spontaneous dehydrogenation) led to phenanthrene-9-thiol (IX), the corresponding disulfide X, and the S-(2-dimethylaminoethyl) derivatives XI and XIV. Reactions of 5-chloro-5,7-dihydrodibenzo[c,e]thiepin (II) with the corresponding Grignard reagents were only a poor source of the amines III and IV. Reaction of the sulfoxide XVIII with n-butyllithium or with sodium hydride and the following treatment with 2-dimethylaminoethyl chloride gave the amine XIX in a low yield. Only the sulfone X was found more useful for preparing the 5- and 5,7-substituted derivatives. Treatment with n-butyllithium and following carbonation afforded mixtures of the monocarboxylic acid XXI and dicarboxylic acid XXVIII. Via acid chlorides they were transformed to the methylamides XXII and XXIX, and to the dimethylamides XXIII and XXX. The amide XXIII was reduced to the 5-(dimethylaminomethyl) compound XXV. Lithiation of the sulfone XX or treatment with sodium hydride, and the following action of 2-dimethylaminoethyl chloride and 3-dimethylaminopropyl chloride gave the amines XXVI, XXVII, and XXXI. Only the phenanthrene derivatives XI and XIV, and the amino sulfone XXVII showed clear indications of thymoleptic activity as potential antidepressants.
