Dual 5-HT1A agonists and 5-HT re-uptake inhibitors by combination of indole-butyl-amine and chromenonyl-piperazine structural elements in a single molecular entity
摘要:
The dual serotonin (5-HT) re-uptake inhibitor and 5-HT1A receptor agonist vilazodone was found to increase central serotonin levels in rat brain. In the course of structural modifications of vilazodone 3-{4-[4-(2-oxo-2H-1-benzopyran-6-yl)-1-piperazinyl]-butyl}-1H-indole-5-carbonitrile 8i and its fluorine analogue 6-{4-[4-(5-fluor-3-indolyl)-butyl]-1-piperazinyl}-2H-1-benzopyran-2-one have been identified. These unsubstituted chromenones are equally potent at the 5-HT1A receptor and 5-HT transporter. The implementation of nitrogen functionalities in position 3 of the chromenones resulted in compounds acting as agonists at the 5-HT1A receptor and as 5-HT re-uptake inhibitors like vilazodone. Ex vivo 5-HT re-uptake inhibition and in vitro 5-HT agonism were determined in the PCA- and GTRgammaS-assay, respectively. The potential of these chromenones to increase central 5-HT levels was measured in microdialysis studies and especially the derivatives 3-{4-[4-(3-amino-2-oxo-2H-chromen-6-yl)-piperazin-1-yl]-butyl-1H-indole-5-carbonitrile 8f, ethyl (6-{4-[4-(5-cyano-1H-indol-3-yl)-butyl]-piperazin-1-yl}-2-oxo-2H-chromen-3-yl)-carbamate 8h and N-(6-{4-[4-(5-cyano-1H-indol-3-yl)-butyl]-piperazin-1-yl}-2-oxo-2H-chromen-3-yl)-acetamide 8k give rise to rapid development of increased serotonin levels in rat brain cortex, lasting longer than 3h.

The invention relates to a compound of general formula I, II, III, IV, V, VI, VII, VIII, IX, X or a tautomer and the stereochemically isomeric forms thereof or pharmaceutically acceptable salts thereof, a N-oxide form thereof or a pro-drug thereof. The compound is usable as a medicament for the treatment of mycobacterial disease.
our molecular modelling and dockingstudies on well-known diarylquinoline antitubercular drug R207910, the presence of phenyl, naphthyl and halogen moieties seem critical. Comparison of dockingstudies on different stereoisomers of R207910 as well as compounds from our data set, suggests importance of electrostatic interactions. Further structural analysis of dockingstudies on our compounds suggests

We report the synthesis and X-ray crystalstructures of three acyclic CB[n]-type molecular containers (2a, 2h, 2f) that differ in the charge on their solubilizing groups (SO3−, OH, NH3+). The X-ray crystalstructures of compounds2h and 2f reveal a self-folding of the ArOCH2CH2X wall into the cavity driven by π–π interactions, H-bonds and ion–dipole interactions. The need to reverse this self-folding
