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

Glycosyl 6-nitro-2-benzothiazoate. A highly efficient donor for beta-stereoselective glycosylation

Highly beta-stereoselective glycosylations of glycosyl acceptors having a primary hydroxyl group by using a novel glycosyl donor, alpha-glycosyl 6-nitro-2-benzothiazoate (3), proceeded smoothly in the presence of a catalytic amount of trifluoromethanesulfonic acid (TfOH) in CH2Cl2 at -78C to afford the corresponding glycosides in high yields. The donor 3 gave beta-saccharides more dominantly compared with those using other alpha-glycosyl donors such as thioform- and trichloroacet-imidates or fluoride under the same conditions.

Solid phase synthesis of peptidoglycan monomers for the generation of a combinatorial library

Solid phase synthesis of peptidoglycan monomers was conducted by coupling the corresponding lipid-bearing glycocarboxylic acids to resin-bound peptides. The efficiency of coupling reagents was found to be in descending order of HATU > HBTU > PyBOP > EEDQ. There was no obvious difference in coupling yield between conducting the solid phase synthesis on polystyrene resins or on polyethylene glycol grafted polystyrene resins.

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.COA of Formula: C8H15NO6, you can also check out more blogs about14215-68-0

Application of 499-40-1, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11.

Synthetic, structural and magnetic implications of introducing 2,2?-dipyridylamide to sodium-ferrate complexes

Using a transamination approach to access novel Fe(ii) complexes, this study presents the synthesis, X-ray crystallographic and magnetic characterisation of a series of new iron complexes containing the multifunctional 2,2-dipyridylamide (DPA) ligand using iron bis(amide) [{Fe(HMDS)2}2] and sodium ferrate [{NaFe(HMDS)3}?] (1) as precursors (HMDS = 1,1,1,3,3,3-hexamethyldisilazide). Reactions of DPA(H) with 1 show exceptionally good stoichiometric control, allowing access to heteroleptic [(THF)2¡¤NaFe(DPA)(HMDS)2] (3) and homoleptic [{THF¡¤NaFe(DPA)3}?] (4) by using 1 and 3 equivalents of DPA(H), respectively. Linking this methodology and co-complexation, which is a more widely used approach to prepare heterobimetallic complexes, 3 can also be prepared by combining NaHMDS with heteroleptic [{Fe(DPA)(HMDS)}2] (2). In turn, 2 has been also synthesised and structurally defined by reacting [{Fe(HMDS)2}2] with two equivalents of DPA(H). Structural studies demonstrate the coordination flexibility of the N-bridged bis(heterocycle) ligand DPA, with 2 and 3 exhibiting discrete monomeric motifs, whereas 4 displays a much more intricate supramolecular structure, with one of its DPA ligands coordinating in an anti/anti fashion (as opposed to 2 and 3 where DPA shows a syn/syn conformation), which facilitates propagation of the structure via its central amido N. Magnetic studies confirmed the high-spin electron configuration of the iron(ii) centres in all three compounds and revealed the existence of weak ferromagnetic interactions in dinuclear compound 2 (J = 1.01 cm-1).

Purification and characterization of lectins from jute (Chorchorus olitorius) leaves

Three lectins were isolated from an extract of jute leaves (Chorchorus olitorius) and purified by gel filtration on Sephadex G-50 of the 100% ammonium sulfate saturated crude extract, followed by ion-exchange chromatography on DEAE-cellulose were designated as JLL-1, JLL-2 and JLL-3. All the lectins were homogeneous as judged by SDS-polyacrylamide slab gel electrophoresis and gave single bands. The molecular weights of the three lectins were estimated by the same method were 35000, 38000 and 42000, respectively. The lectins specifically agglutinated rat red blood cells. The agglutination of JLL-1 was inhibited by D-mannose/D-glucose and their derivatives, whereas D-galactose was found to be the potent inhibitor for the agglutination of JLL-2 and JLL-3. The lectins were glycoprotein in nature with a neutral sugar content of 1.3%, 1.2% and 0.8% for JLL-1, JLL-2 and JLL-3, respectively. The hemagglutinating activity of JLL-2 was also investigated after the treatment of physico-chemical agents. The lectin showed maximum activity between the range of pH 7.2-8.0 and the range of temperature of 20-30C. The activity of lectin decreased after treatment with a higher concentration of acetic acid and urea. In the presence EDTA the activity was inhibited while the presence of Ca+2, Mn+2 and K+ increased the activity of the lectin moderately.
