Chemo-enzymatic approach to access diastereopure alpha-substituted GlcNAc derivatives

The formation of diastereopure alpha-substituted GlcNAc derivatives in a simple and straightforward way is a challenging task. Herein, we report the chemical synthesis of diastereomeric alpha/beta-substituted GlcNAc derivatives under non-anhydrous atmosphere using unprotected GlcNAc, followed by a selective enzymatic hydrolysis step using a bacterial N-acetyl-hexosaminidase to provide only alpha-substituted GlcNAc. This enzyme proved to selectively hydrolyze the beta-anomeric GlcNAc derivatives, while the alpha-anomeric GlcNAc derivatives remained unreacted. The released GlcNAc (and therefore the alpha/beta ratios) could be quantified using a coupled enzymatic assay consisting of GlcNAc 2-epimerase and N-acetyl- mannosamine dehydrogenase in a simple and accurate way.

Process research and development for the kilogram manufacture of the SRC kinase inhibitor AZD0530

Process research and development of a synthetic route towards a novel SRC kinase inhibitor is described. The Medicinal Chemistry route was very long and suffered from extensive use of chlorinated solvents and chromatography. A number of steps in the Medicinal Chemistry route were also unattractive for large-scale use for a variety of reasons. The route was modified to produce a shorter synthetic scheme that started from more readily available materials. By using the modified route, the title compound was manufactured on kilogram scale without recourse to chromatography and in significantly fewer steps. The scaled synthesis required two Mitsunobu couplings, which were developed and scaled successfully. An interesting hydrazine impurity was identified in the second Mitsunobu coupling; a mechanism for its formation is proposed, and a method for its control is described. The formation and control of some other interesting impurities are also described.

Diarylamino functionalized pyrene derivatives for use in blue OLEDs and complex formation

Three new 2,2?-dipyridylamino functionalized pyrene derivatives, 1-pyrenyl-2,2?-dipyridylamine (1), 4-(1-pyrenyl)phenyl-2,2?- dipyridylamine (2), and 4-[4?-(1-pyrenyl)biphenyl]-2,2?- dipyridylamine (3) have been synthesized and fully characterized. For comparison of electronic properties, a diphenylamino functionalized molecule 4-[4?-(1-pyrenyl)biphenyl]diphenylamine (4) has also been synthesized. Compounds 1-4 are bright blue emitters in solution and in the solid state with lambdamax at ?420-460 nm and a high emission efficiency in solution. All four compounds form amorphous glasses with Tg values of 66 C, 79 C, 165 C, and 98 C, respectively. The electronic properties of the four compounds were examined by spectroscopic methods, cyclic voltammetry and Gaussian 98 molecular orbital calculations. The utilities of this class of molecules in OLEDs have been demonstrated by EL devices of compounds 3 and 4, which showed that 3 can function as a bright blue emitter and an electron transport material in a double-layer device while 4 can function as a bright blue emitter and a hole transport molecule in a triple-layer device. The dipyridylamino functional group in molecules 1-3 are capable of chelating to metal ions such as Zn(II) as demonstrated by the synthesis and structure of the complex [2-(Zn(O2CCF3) 2]2 (5). The binding of Zn(II) ions to the dipyridyl group causes a reduction of the emission efficiency of the ligand 2.

Ni(II) complexes with 2,2-dipyridylamine and salicylaldehydes: Synthesis, crystal structure and interaction with calf-thymus DNA and albumins

The synthesis of four cationic mixed?ligand Ni(II) complexes with 2,2??dipyridylamine (dpamH) and substituted salicylaldehydes (X?saloH) was undertaken in an effort to discover new biologically active compounds. The complexes with the general formula [Ni(dpamH)2(X?salo)]Cl, 3?6, namely [Ni(dpamH)2(5?Cl?salo)]Cl, 3, [Ni(dpamH)2(5?Br?salo)]Cl, 4, [Ni(dpamH)2(5?CH3?salo)]Cl, 5, and [Ni(dpamH)2(3?OCH3?salo)]Cl¡¤CH3OH, 6, were characterized by elemental analyses, FT?IR and UV?vis spectroscopy, magnetic and conductivity measurements. In addition, two analogous nickel?salicylaldehydato complexes in the absence of dpamH were prepared and characterized as [Ni(5?Cl?salo)2(CH3OH)2], 1 and [Ni(5?Br?salo)2(CH3OH)2], 2. The structures of complexes 1?6 were determined by X?ray crystallography revealing octahedral coordination of nickel (II) and monomeric nature of the compounds. Spectroscopic (UV?vis), electrochemical (cyclic voltammetry) and physicochemical (viscosity measurements) techniques were employed in order to study the binding mode and strength of the complexes to calf?thymus (CT) DNA, while competitive studies with ethidium bromide (EB), performed by fluorescence spectroscopy, revealed the ability of the complexes to displace the DNA-bound EB. The complexes bind to DNA probably via intercalation exhibiting high DNA?binding constants. For the cationic complexes 3?6, the coexistence of an electrostatic interaction with CT DNA may be also suggested. The interaction of the complexes with serum albumins was studied by fluorescence emission spectroscopy and the determined binding constants exhibit relative high values.
