A simplified process for the manufacture of AZD0530, a potent SRC kinase inhibitor

An efficient process for the manufacture of AZD0530 1, a potent SRC kinase inhibitor, has been developed. The key transformation, reaction of monofluoroanilide 7 with alcohol 8, was much simplified between manufacturing campaigns. The development of a robust, efficient, and scalable process for this transformation drew on both a practical and theoretical understanding of the process and is described herein

Development of a Novel Biocatalyst for the Resolution of rac-Pantolactone

A novel L-pantolactone hydrolase, Lph, from Agrobacterium tumefaciens Lu681 was characterized, which stereospecifically hydrolyses L-pantolactone to L-pantoic acid yielding D-pantolactone with > 95% enantiomeric excess. The enzyme was found to be a 30 kDa-Zn2+-hydrolase with a Km for L-pantolactone of 7 mM and a Vmax of 30 U/mg. The corresponding lph gene was identified as an 807 bp ORF and cloned into E. coli. It was overexpressed under control of Ptac and Prha yielding enzyme activities of up to 600 U/g dry weight. Resolution of D,L-pantolactone in repeated batches with isolated Lph and enzyme recovery by membrane filtration gave D-pantolactone with 50% yield and 90-95% ee over 6 days. Covalent immobilization to EupergitC led to a stable biocatalyst easy to handle in a repeated batch production of D-pantolactone. Further improvements in the activity of Lph were achieved by directed evolution of the enzyme. Activities of mutants F62S, K197D and F100L were increased 2.3, 1.7, and 1.5 fold, respectively.

Synthesis of carbohydrate-based azamacrocycles by Richman-Atkins cyclisation

Symmetrical nitrogen containing ring structures with two or four glucose units were easily obtained from accessible monosaccharide building units. Various tetherings via 4,4′- and 6,6′-positions lead to a variety of precursors which were transformed successively employing different bridging units by Richman-Atkins cyclisation to result in defined glycophane coronands.

Androgen receptor affinity of 5′-acyl furanosteroids

Syntheses of 5′-acyl furanosteroids are described from the corresponding unsubstituted [3,2-b]furanosteroids using acid anhydrides and acid chlorides in the presence or absence of Lewis acids. New methods have been developed to prepare 5′-acetyl derivatives: reduction of a 5′-trichloroacetyl intermediate either by sodium formaldehyde sulfoxylate or with 10% Pd/C. Most of these 5′- acyl derivatives bind to the rat ventral prostate androgen receptor. However the antiandrogenic activity was diminished when compared with 4, 5′- methylsulfonyl furanosteroid. Biological studies revealed that 5′-acyl furanosteroids were either androgens or modest antiandrogens. The electrostatic potential maps of the substructures of 3, 4, and 5′-acetyl syn- and anti-furanosteroids showed striking differences which may explain, to some extent, the lack of significant antiandrogenic activity of 5′-acyl furanosteroids.

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.Safety of Methyl 2-((tetrahydro-2H-pyran-2-yl)oxy)acetate, you can also check out more blogs about135643-82-2

Characterization of off-odours and potentially harmful substances in a fancy dress accessory handbag for children

A fancy dress accessory handbag for children was claimed by consumers to exhibit an offensive smell. Sensory characterization by an expert panel revealed, amongst others, rubber- and car tire – like notes. For elucidation of the molecular reasons of this sensory defect, the volatile fraction of the product was isolated by means of solvent extraction and high vacuum distillation. Identification of the main odorants was accomplished by means of one- and two-dimensional gas chromatography, with parallel mass spectrometric and olfactometric detection. In total more than 60 odorants were detected in the sample and more than 30 of these odour-active substances could be identified. Amongst them were a number of naphthalene derivatives as well as saturated and mono- or di-unsaturated carbonyl compounds. The naphthalene derivatives that were identified in the children’s article appeared to be mainly responsible for the characteristic off-odour. Additionally, a GC-MS-screening for polycyclic aromatic hydrocarbons (PAHs) was performed, which revealed the presence of 15 PAHs in total. However, 14 of them were of no relevance for the smell of the product.

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 3301-94-8 is helpful to your research., Related Products of 3301-94-8
