Inspired by VUF6884 (7-Chloro-11-(4-methylpiperazin-1-yl)dibenzo[b,f][1,4]oxazepine), reported as a dual H1/H4 receptor ligand (pKi: 8.11 (human H1R (hH1R)), 7.55 (human H4R (hH4R))), four known and 28 new oxazepine and related oxepine derivatives were synthesised and pharmacologically characterized at histamine receptors and selected aminergic GPCRs. In contrast to the oxazepine series, within the oxepine series, the new compounds showed high affinity to the hH1R (pKi: 6.8–8.7), but no or moderate affinity to the hH4R (pKi: ≤ 5.3). For one oxepine derivative (1-(2-Chloro-6,11-dihydrodibenzo[b,e]oxepin-11-yl)-4-methylpiperazine), the enantiomers were separated and the R-enantiomer was identified as the eutomer at the hH1R (pKi: 8.83 (R), 7.63 (S)) and the guinea-pig H1R (gpH1R) (pKi: 8.82 (R), 7.41 (S)). Molecular dynamic studies suggest that the tricyclic core of the compounds is bound in a similar mode into the binding pocket, as described for doxepine in the hH1R crystal structure. Moreover, docking studies of all oxepine derivatives at the hH1R indicate that the oxygen and the position of the chlorine in the tricyclic core determines, if the R- or the S-enantiomer is the eutomer. For some of the oxazepines and oxepines the affinity to other aminergic GPCRs is in the same range as to hH1R or hH4R, thus, those compounds have to be classified as dirty drugs. However, one oxazepine derivative (3,7-Dichloro-11-(4-methylpiperazin-1-yl)dibenzo[b,f][1,4]oxazepine was identified as dual hH1/h5-HT2A receptor ligand (pKi: 9.23 (hH1R), 8.74 (h5-HT2AR), ≤7 at other analysed GPCRs), whereas one oxepine derivative (1-(3,8-Dichloro-6,11-dihydrodibenzo[b,e]oxepin-11-yl)-4-methylpiperazine) was identified as selective hH1R antagonist (pKi: 8.44 (hH1R), ≤6.7 at other analyzed GPCRs). Thus, the pharmacological results suggest that the oxazepine/oxepine moiety and additionally the chlorine substitution pattern toggles receptor selectivity and specificity.

Novel matrix metalloproteinase (MMP)/bacterial collagenase inhibitors are reported, considering the sulfonylated amino acid hydroxamates as lead molecules. A series of compounds was prepared by reaction of arylsulfonyl isocyanates with N-(5H-dibenzo[a,d]cyclohepten-5-yl)- and N-(10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5-yl) methyl glycocolate, respectively, followed by the conversion of the COOMe to the carboxylate/hydroxamate moieties. The corresponding derivatives with methylene and ethylene spacers between the polycyclic moiety and the amino acid functionality were also obtained by related synthetic strategies. These new compounds were assayed as inhibitors of MMP-1, MMP-2, MMP-8 and MMP-9, and of the collagenase isolated from Clostridium histolyticum (ChC). Some of the new derivatives reported here proved to be powerful inhibitors of the four MMPs mentioned above and of ChC, with activities in the low nanomolar range for some of the target enzymes, depending on the substitution pattern at the sulfonylureido moiety and on the length of the spacer through which the dibenzosuberenyl/suberyl group is connected with the rest of the molecule. Several of these inhibitors also showed selectivity for the deep pocket enzymes (MMP-2, MMP-8 and MMP-9) over the shallow pocket ones MMP-1 and ChC.

11-Chloro-6,11-dihydrodibenzothiepin and its 2-methyl derivative VI were transformed via the 11-(4-(ethoxycarbonyl)-1-piperazinyl) compounds IVc and Vc to 11-(1-piperazinyl) compounds IVb and Vb.Their reactions with 1-(3-chloropropyl)-1,3-dihydro-2H-benzimidazol-2-one (II) afforded the title compounds IVa and IVb.Similar reactions and sequences in the series of 10,11-dihydro-5H-dibenzocycloheptene, 4,9-dihydrothieno-2-benzothiepin, and 10,11-dihydrodibenzothiepin led to further oxatomide (Ia) analogues IIIa and VIIa-XIa.In the test of passivecutaneous anaphylaxis in rats, compound VIIIa was more active than Ia, and IVa had similar activity like Ia.
