Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 1-(Bis(4-chlorophenyl)methyl)piperazine, is researched, Molecular C17H18Cl2N2, CAS is 27469-61-0, about Development and validation of an in silico P450 profiler based on pharmacophore models. Author is Schuster, Daniela; Laggner, Christian; Steindl, Theodora M.; Langer, Thierry.

In today’s drug discovery process, the very early consideration of ADME properties is aimed at a reduction of drug candidate drop out rate in later development stages. A part from in vitro testing, in silico methods are evaluated as complementary screening tools for compounds with unfavorable ADME attributes. Especially members of the cytochrome P 450 (P 450) enzyme superfamily. e.g. P 450 1A2, P 450 2C9, P 450 2C19, P 450 2D6, and P 450 3A4, contribute to xenobiotic metabolism, and compound interaction with one of these enzymes is therefore critically evaluated. Pharmacophore models are widely used to identify common features amongst ligands for any target. In this study, both structure-based and ligand-based models for prominent drug-metabolizing members of the P 450 family were generated employing the software packages LigandScout and Catalyst. Essential chem. ligand features for substrate and inhibitor activity for all five P 450 enzymes investigated were determined and analyzed. Finally, a collection of 11 pharmacophores for substrates and inhibitors was evaluated as an in silico P 450 profiling tool that could be used for early ADME estimation of new chem. entities.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions.

Keywords: medicinal chem drug discovery high throughput synthesis. Let’s learn more about this compound (cas:97739-46-3).

At the forefront of new synthetic endeavors, such as drug discovery or natural product synthesis, large quantities of material are rarely available and timelines are tight. A miniaturized automation platform enabling high-throughput experimentation for synthetic route scouting to identify conditions for preparative reaction scale-up would be a transformative advance. Because automated, miniaturized chem. is difficult to carry out in the presence of solids or volatile organic solvents, most of the synthetic toolkit cannot be readily miniaturized. Using palladium-catalyzed cross-coupling reactions as a test case, we developed automation-friendly reactions to run in DMSO at room temperature This advance enabled us to couple the robotics used in biotechnol. with emerging mass spectrometry-based high-throughput anal. techniques. More than 1500 chem. experiments were carried out in less than a day, using as little as 0.02 mg of material per reaction. The synthesis of the target compounds was achieved using as starting materials N-(1,1-dimethylethyl)-4′-[(6-iodo-4-oxo-2-propyl-3(4H)-quinazolinyl)methyl][1,1′-biphenyl]-2-sulfonamide, (5R)-3-(3-fluoro-4-iodophenyl)-5-(1H-1,2,3-triazol-1-ylmethyl)-2-oxazolidinone, 7-[(3-bromo-4-methoxyphenyl)methyl]-1-ethyl-3,7-dihydro-8-[[(1R,2R)-2-hydroxycyclopentyl]amino]-3-(2-hydroxyethyl)-1H-purine-2,6-dione.
