Synthetic Route of C5H7Br. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 1-Bromo-2-pentyne, is researched, Molecular C5H7Br, CAS is 16400-32-1, about Coumarin-Rasagiline Hybrids as Potent and Selective hMAO-B Inhibitors, Antioxidants, and Neuroprotective Agents. Author is Matos, Maria J.; Herrera Ibata, Diana M.; Uriarte, Eugenio; Vina, Dolores.

The frequency, complexity and morbidity of neurodegenerative diseases make them a great challenge for nowadays medicine. Most of the treatments currently used for Parkinson’s disease – the second most prevalent – are only symptomatic. Therefore, it is urgent to develop drugs that are able to act simultaneously on different targets, being able to stop neuronal death and promote the recovery of neuronal populations already affected. In this work, we studied the activity of a series of hybrid mols., which combine the structure of both coumarin and an alkynylamine group inspired on rasagiline, as MAO inhibitors, antioxidants and neuroprotective agents. Half of the studied hybrids turned out to be selective monoamine oxidase B (hMAO-B) inhibitors in the low micro/nanomolar range, demonstrating that positions 3 (compounds 1-3) and 7 (compounds 8 and 10) of the coumarin scaffold are the most suitable for the incorporation of the alkynylamine chain. All the studied compounds proved to be capable of neutralizing free radicals (DPPH). Finally, the 4-(but-2-yn-1-ylamino)coumarin (5) showed neuroprotective effects on glial cells and the 4-methyl-7-(pent-2-yn-1-ylamino)coumarin (8) inhibited intraneuronal ROS production as well.

Safety of 1-(Bis(4-chlorophenyl)methyl)piperazine. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of 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.

Product Details of 50501-07-0. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Ethyl indoline-2-carboxylate, is researched, Molecular C11H13NO2, CAS is 50501-07-0, about α2-Adrenergic agonists/antagonists: the synthesis and structure-activity relationships of a series of indolin-2-yl and tetrahydroquinolin-2-yl imidazolines. Author is Hlasta, Dennis J.; Luttinger, Daniel; Perrone, Mark H.; Silbernagel, Marla J.; Ward, Susan J.; Haubrich, Dean R..

The synthesis and α2-adrenergic activity of a series of indolin-2-yl- and tetrahydroquinolin-2-ylimidazolines, e.g. I (R = Me, Et, allyl, Ph, CH2Ph, etc.; R1 = 5-F, 5-Cl, etc.) and II (R = H, Me) are described. The indolin-2-ylimidazoline I (R = Me, R1 = H) has potent α2-adrenergic agonist and antagonist activity. The modification of the substituents on the indoline ring of I led to the separation of these activities. Substitution on the aromatic ring of I with halogen or increasing the size of the N-alkyl substituent of I gave α2-adrenergic antagonists without agonist activity. The N-allylindoline I (R = allyl, R1 = H) is more potent than idazoxan in vitro and is equipotent in vivo, but is less receptor-selective (α2 vs. α1) than idazoxan. cis-1,3-Dimethylindolin-2-ylimidazoline is an α2-adrenergic agonist equal in potency to clonidine in vitro, whereas trans-1,3-dimethylindolin-2-ylimidazoline is a moderately potent α2-adrenergic antagonist.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 97739-46-3, is researched, Molecular C16H21O3P, about Tandem and One-Pot Hydroformylation/Michael Reactions of Acrylates, the main research direction is hydroformylation Michael tandem acrylate rhodium catalyst; carbonyl compound preparation tandem hydroformylation Michael aldol rhodium catalyst.Name: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane.

The combination of various reactions in one operational step leads to many advantages in synthetic strategies, such as a lower consumption of resources, effort, and time, when intermittent workup and purification steps can be avoided. The hydroformylation reaction of acrylates gives access to 2-formylpropanoates, which, thanks to their structural features, constitute useful intermediates in the synthesis of more complex compounds Herein, we report a simple and convenient one-pot strategy to synthesize functionalized carbonyl compounds starting from these readily available substrates, via tandem or one-pot hydroformylation, Michael addition, and aldol reactions.

Reference of 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane, is researched, Molecular C16H21O3P, CAS is 97739-46-3, about Titanium Complexes of Sterically Demanding Cage-Phosphinimide Ligands.

The known ligand PPh(C6H4O3Me4) (1) and its analog PCy(C6H4O3Me4) (2) have been prepared In the latter synthesis the diphosphine species (PCy)2(C6H2O3Me4) (3) was also isolated as a minor product. Reaction of the cage phosphines 1 and 2 with Me3SiN3 effected oxidation to the corresponding (trimethylsilyl)phosphinimines Me3SiNPR(C6H4O3Me4) (R = Ph (4), Cy (5)). Subsequent reactions afforded the titanium complexes CpTiCl2(NPR(C6H4O3Me4)) (R = Ph (6), Cy (7)) and CpTiMe2(NPR(C6H4O3Me4)) (R = Ph (8), Cy (9)). Preliminary screening for catalytic activity in ethylene polymerization employing either methylalumoxane (MAO) or [Ph3C][B(C6F5)4] as the activator showed minimal catalytic activity. These observations were probed via reactions of these complexes with AlMe3, MAO, or [Ph3C][B(C6F5)4]. Reaction of 8 with AlMe3 gave several products, one of which was fully characterized as the cage-rupture product CpTiMe2(NPCy(C6H4O3Me5)(μ-AlMe2)(AlMe3)) (10). A similar product is inferred by the spectroscopic monitoring of the reaction of 8 with MAO. In contrast, reaction of 2 with AlMe3 resulted only in the formation of the adduct Me3AlPCy(C6H4O3Me4) (11). Structural data are reported for 2, 3, 8, 10, and 11.
