Chemoenzymatic synthesis of piperoxan, prosympal, dibozane, and doxazosin

The synthesis of both enantiomers of 1,4-benzodioxan-2-carboxylic acid 1, a key synthetic intermediate for the therapeutic agents piperoxan, prosympal, dibozane, and doxazosin was achieved with good yields and high enantioselectivities via the Arthrobacter sp. lipase catalyzed kinetic resolution of ester (¡À)-17a. The influence of the co-solvents and the immobilization of the lipase upon kinetic resolution demonstrated that immobilized whole cells, in the presence of n-butanol as a co-solvent, resulted in the optimal resolution of the substrate (ee ?99%, E = 535) at 258 mmol (50 g/L) substrate concentration.

Pyrido pyrimidinones as selective agonists of the high affinity niacin receptor GPR109A: Optimization of in vitro activity

Pyrido pyrimidinones are selective agonists of the human high affinity niacin receptor GPR109A (HM74A). They show no activity on the highly homologous low affinity receptor GPR109B (HM74). Starting from a high throughput screening hit the in vitro activity of the pyrido pyrimidinones was significantly improved providing lead compounds suitable for further optimization.

Hypervalent Iodine(III)-Mediated Oxidative Fluorination of Alkylsilanes by Fluoride Ions

The first example of a hypervalent iodine(III)-mediated oxidative fluorination of alkylsilanes by fluoride ions without the use of transition metals is demonstrated. This reaction is operationally simple, scalable, and proceeds under mild reaction conditions. Mechanistic studies suggest the involvement of a single-electron transfer resulting from the interaction of an organopentafluorosilicate and aryliodonium difluoride, which were generated in situ from the corresponding alkylsilane and iodosobenzene, respectively, in the presence of fluoride ions.

Analysis of crystallographic structures of Ni(II) complexes of alpha-amino acid Schiff bases: Elucidation of the substituent effect on stereochemical preferences

In this study, we performed critical analysis of 13 crystallographic structures of various Ni(ii) complexes of amino acid Schiff bases. The major finding of this work is the significance of a parallel displaced type of aromatic interactions between o-amino-benzophenone and Pro N-benzyl rings. The quality of these aromatic interactions was shown to control the steric environment around the amino acid side-chain, rendering variously substituted Ni(ii) complexes of different thermodynamic stabilities. The discovered structural trend holds true for aliphatic, aromatic and sterically bulky amino acids and can be used for the rational design of new and more efficient chiral ligands for general asymmetric synthesis of tailor-made alpha-amino acids.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4442-59-5 is helpful to your research. Synthetic Route of 4442-59-5

Copper/Persulfate-Promoted Oxidative Decarboxylative C?H Acylation of Pyrazolones with alpha-Oxocarboxylic Acids: Direct Access to 4-Acylpyrazolones under Mild Conditions

A facile and efficient oxidative C?H acylation of N-substituted pyrazolones using alpha-oxocarboxylic acids as an acyl group source was developed. A combination of Cu(OAc)2 and K2S2O8 enables the reaction to proceed smoothly under air and provides a wide array of 4-acylpyrazolone products in moderate to excellent yields. The mechanism of this transformation is believed to proceed via a copper-induced decarboxylation to form the acyl-copper species. This method provides a convenient and useful route for a direct installation of an acyl moiety into bioactive pyrazolone derivatives, which can be further utilized in many applications. (Figure presented.).

2-Aralkoxyadenosines: Potent and Selective Agonists at the Coronary Artery A2 Adenosine Receptor

A Langendorff guines pig heart preparation served for the assay of agonist potency of a series of 26 2-aralkoxyadenosines at the A1 and A2 receptors of, respectively, the atrioventricular node (conduction block) and coronary arteries (vasodilation).All of the analogues are weak agonists at the A1 receptor, requiring concentrations >9 muM to cause second degree heart block.At the A2 receptor 2-phenethoxyadenosine is the most potent of the 2-phenylalkyladenosines.The activity of ring-substituted (F, Cl, CH3, and OCH3) 2-phenethoxyadenosines increases ortho < meta < para.The EC50s of coronary vasoactivity of several para-substituted analogues are in the subnanomolar range.The most potent analogue, 2-<2-(4-methylphenyl)ethoxy>adenosine 19, has an EC50 for coronary vasodilation of 190 pM and an A1/A2 selectivity ratio of 44000.Aryl groups such as thienyl, indoloyl, or naphthyl also support A2 agonist activity.Although 2-oxoadenosine is 3 times more vasoactive than 2-aminoadenosine, the activites of the phenyl derivatives are markedly different; 2-phenoxyadenosine is 23 times weaker than 2-(phenylamino)adenosine (CV-1808).

Target-oriented synthesis: Miscellaneous synthetic routes to access 1,4-enediones through the coupling of 1,3-dicarbonyl compounds with multiform substrates

Target-oriented synthetic protocol was presented for the synthesis of 1,4-enediones. The approach can efficiently construct 1,4-enediones through different reaction pathways from multiform substrates alpha-halo aromatic ketones, 2-hydroxy-aromatic ketones and methyl carbinols. In this reaction, CuI was found to be the most efficient catalyst. Multiform substrates were also found to perform well to afford the products in a one-pot fashion.

Molecular docking studies and biological evaluation of chalcone based pyrazolines as tyrosinase inhibitors and potential anticancer agents

Studies on the discovery of tyrosinase enzyme inhibitors and exploration for better cytotoxic agents remain an important line in drug discovery and development. A series of synthetic chalcones and pyrazoline derivatives was evaluated for their inhibitory effects on the diphenolase activity of mushroom tyrosinase. The effects of these compounds on proliferation and microtubule assembly were also evaluated in seven different cancer cell lines. The results revealed that some of the synthetic compounds showed significant inhibitory activity, with four compounds being more potent tyrosinase inhibitors than the reference standard inhibitor kojic acid. Several compounds were toxic to cancer cell lines. Compound 1a was found to possess the highest anticancer activity towards all cell lines with an IC50 in the range of 0.9-2.2 muM. Seven of the compounds showed considerable tubulin polymerization activity at a concentration of 25 muM. Molecular modeling studies of these synthetic compounds were performed to investigate their interactions with the tyrosinase enzyme. The structure-activity relationship (SAR) study using in-silico analysis matched well with the in vitro tumour cell inhibitory activity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 2879-20-1, you can also check out more blogs about2879-20-1
