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, the main research direction is indolinylimidazoline preparation adrenergic agonist antagonist; quinolinylimidazoline preparation adrenergic agonist antagonist; structure activity adrenergic indolinylimidazoline.HPLC of Formula: 50501-07-0.

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.

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.Nagy, P. I.; Tokarski, John; Hopfinger, A. J. researched the compound: 1-(Bis(4-chlorophenyl)methyl)piperazine( cas:27469-61-0 ).HPLC of Formula: 27469-61-0.They published the article 《Molecular Shape and QSAR Analyses of a Family of Substituted Dichlorodiphenyl Aromatase Inhibitors》 about this compound( cas:27469-61-0 ) in Journal of Chemical Information and Computer Sciences. Keywords: dichlorodiphenyl aromatase inhibitor QSAR. We’ll tell you more about this compound (cas:27469-61-0).

Conformational analyses of three families of substituted dichlorodiphenyl aromatase inhibitors indicated that both potent and weak inhibitors adopt a common global min. energy conformation. Further, this global min. energy conformation is the only meaningful intramol. conformer state that can be energetically realized and is virtually identical to the crystal structure of one of the analogs. Quant. structure-activity relationships, QSARs, were sep., and jointly, developed for two series of inhibitors. The distance, D, of a nitrogen atom in the variable heterocyclefrom the core Cc atom is the most important activity descriptor. The optimum distance between the nitrogen and Cc to maximize inhibitor potency is about 3.6 Å for both classes of analogs. Integrated potential energy field difference calculations were also carried out using a proton probe and some of the variable heterocycles. The field calculations coupled with the QSAR studies suggest that the nitrogen 3.6 Å from Cc acts as a hydrogen bond acceptor. Two possible three-dimensional pharmacophores are proposed for effective aromatase inhibitors.

Keywords: unsaturated amide regioselective preparation; palladium catalyst aminocarbonylation alkyne aminophenol carbon monoxide. Let’s learn more about this compound (cas:97739-46-3).

This work describes the chemo- and regioselective direct aminocarbonylation of alkynes withh aminophenols to form hydroxy-substituted α,β-unsaturated amides in good to excellent yields. The latter are valuable compounds in pharmaceuticals and natural products. By a simple choice of different ligands and additives, branched or linear isomers could be selectively formed in excellent regioselectivity. Using a combination of boronic acid and 5-chlorosalicylic acid (“”BCSA””) as the additives, linear amides were obtained in high yields and selectivities using 1,2-bis(di-tert-butylphosphinomethyl)benzene (DTBPMB) as the ligand. On the other hand, branched amides could be approached by introducing 1,3-bis(diphenylphosphino)propane as the ligand and p-TsOH·H2O as the additive. In addition to the hydroxyl group, other functional substituents, such as carboxyl and vinyl groups, could also be tolerated using this method. As an application of this strategy, the natural product avenanthramide A could be synthesized directly in 84% yield and in 99% regioselectivity via the carbonylation of 2-amino-5-hydroxybenzoic acid and 4-ethynylphenol. Further studies show that the ligands and the additives are keys to good yields and selectivities.

Formula: C11H13NO2. 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: Ethyl indoline-2-carboxylate, is researched, Molecular C11H13NO2, CAS is 50501-07-0, about Computational analysis of chiral recognition in Pirkle phases. Author is Lipkowitz, Kenny B.; Baker, Brian.

The relative retention orders and chromatog. separability factors for optical analytes on 2 com. available chiral stationary phases have been determined from statistical mol. modeling. The intermmol. potential-energy surfaces of the diastereomeric complexes formed between the chiral receptor and mirror image substrates are flat and reveal that both enantiomers tend to dock in the same general region around the receptor. How the receptor senses differences between mirror image analytes (enantiorecognition) is revealed with an algorithm that partitions the total binding energy into mol. fragments on the receptor. The fragments on the receptor most responsible for substrate binding are located and the fragments most responsible for enantioselection are discovered. The fragment bearing the stereogenic centers is generally not the most cognizant of differences between mirror image substrates, and the results are generally in agreement with previously proposed chiral recognition models.
