A flexible, multistep parallel synthesis of spiperone analogues is described. A library of 4-substituted piperidines, assembled utilizing reductive amination and acylation protocols, was alkylated either homogeneously or heterogeneously, exploiting a product release only concept, to afford an oxa-series of spiperone analogues. Screening of the products at 5-HT2 and D2 receptors revealed 5-HT(2A) antagonists with improved selectivity compared to spiperone and AMI-193. (C) 2000 Published by Elsevier Science Ltd.

The present research work involved the reaction of 2,3-dihydro-1,4-benzodioxin-6-amine (1) and benzenesulfonyl chloride (2) under dynamic pH control at 10 using aqueous Na2CO3. This reaction yielded 2,3-dihydro-1,4-benzodioxin-6-yl)benzenesulfonamide (3), which was further substituted at N-position with various alkyl/aryl halides (4a ? 4m) in N,N-dimethylformamide and catalytic amount of lithium hydride to obtain N-substituted (2,3-dihydro-1,4-benzodioxin-6-yl)benzenesulfonamides (5a ? 5m). The projected structures of the synthesized derivatives were confirmed using various spectral techniques (IR, 1H NMR and EIMS). The synthesized derivatives were screened for antibacterial potential and inhibitory activity against lipoxygenase enzyme.

The prevalence of solvent effects has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates.

The O-heterocycles, benzo-1,4-dioxane, phthalan, isochroman, 2,3-dihydrobenzofuran, benzofuran, and dibenzofuran are important building blocks with considerable medical application for the production of pharmaceuticals. Cytochrome P450 monooxygenase (P450) Bacillus megaterium 3 (BM3) wild type (WT) from Bacillus megaterium has low to no conversion of the six O-heterocycles. Screening of in-house libraries for active variants yielded P450 BM3 CM1 (R255P/P329H), which was subjected to directed evolution and site saturation mutagenesis of four positions. The latter led to the identification of position R255, which when introduced in the P450 BM3 WT, outperformed all other variants. The initial oxidation rate of nicotinamide adenine dinucleotide phosphate (NADPH) consumption increased ?140-fold (WT: 8.3 ± 1.3 min-1; R255L: 1168 ± 163 min-1), total turnover number (TTN) increased ?21-fold (WT: 40 ± 3; R255L: 860 ± 15), and coupling efficiency, ?2.9-fold (WT: 8.8 ± 0.1%; R255L: 25.7 ± 1.0%). Computational analysis showed that substitution R255L (distant from the heme-cofactor) does not have the salt bridge formed with D217 in WT, which introduces flexibility into the I-helix and leads to a heme rearrangement allowing for efficient hydroxylation.

The D4 receptor is of high interest for research and clinical application but puts high demands on appropriate radioligands to be useful tools for investigation. Search for adequate radioligands suitable for in vivo imaging is therefore still in progress. The potential neuroleptic drug 6-(4-[4-fluorobenzyl]piperazin-1-yl)benzodioxin shows high affinity and selectivity to the D4 receptor. Derivatization of this lead structure by adding hydrophilic moieties was carried out in order to lower its lipophilicity what led to three new putative dopamine receptor D4 ligands. A comprehensive description of the syntheses of standard compounds and corresponding labeling precursors is given which were obtained in satisfactory yields. Furthermore, the radiosyntheses by direct 18F-labeling and build-up synthesis were compared. All derivatives of 6-(4-[4-fluorobenzyl]- piperazin-1-yl)benzodioxin were successfully synthesized in 18F- labeled form with radiochemical yields of 9-35% and molar activities of 30-60 GBq/mumol using one-pot procedures. 2013 John Wiley & Sons, Ltd. Derivatives of the lead structure 6-(4-[4-fluorobenzyl]-piperazine-1-yl) benzodioxin were successfully synthesized, labeled via direct 18F-substitution or build-up synthesis leading to new putative radioligands for imaging of the dopamine D4 receptor. Reductive amination proved as the method of choice for preparation of substituted benzyl-derivatives of piperazine as precursors and standards, and also superior for build-up radiofluorination (RCY = 9 – 35;%) in comparison to direct 18F- labeling (RCY = 1 – 5;%).
