Material for photo-alignment layer, photo-alignment layer and method of manufacturing the same

The present invention provides a photo-alignment layer for a liquid crystal display device, which has good liquid crystal display device characteristics such as a good voltage holding ratio and also has good alignment stability and sufficient resistance to light and heat. The photo-alignment layer is manufactured by coating a polymerizable monomer having at least one photo-alignment moiety, which carries out a photo-alignment function by the photo dimerization reaction, and at least two polymerizable maleimide groups per molecule on a substrate, and exposing the coating layer to light to cause the photo dimerization reaction of the structural unit and the photopolymerization reaction of the polymerizable maleimide group, thereby to form a crosslinked polymeric layer and to enable the polymeric layer to carry out the photo-alignment function.

Novel inhibitors of urease from Corydalis govaniana Wall.

A new compound govaniadine (1), along with three known tetrahydroprotoberberine-type alkaloids caseadine (2), caseamine (3), and protopine (4), were isolated from the plant Corydalis govaniana Wall. All alkaloids 1-4 exhibited a good urease enzyme inhibition with IC50 ¡À S.E.M. values of 20.2 ¡À 3.6, 38.9 ¡À 2.8, 66.7 ¡À 1.2, and 54.1 ¡À 1.2 muM, respectively, which are comparable to the standard inhibitor, acetohydroxamic acid (IC50 = 42.0 muM). None of these compounds showed inhibition against alpha-chymotrypsin. This is the first report of urease inhibiting tetrahydroprotoberberine-type alkaloids.

Aminomethylation of Michael acceptors: Complementary radical and polar approaches mediated by dialkylzincs

Phtalimidomethyl iodide and substituted maleimidomethyl iodide were used as radical precursors in dialkylzinc-mediated radical addition to diethyl fumarate. The reactions led stereoselectively to functionalized pyrrolizidines. The radical mechanism was supported by spin-trapping experiments and rationalized by theoretical calculations. Radical additions, on the one hand, and carbozincation followed by transmetalation with copper(I), on the other, were shown to be complementary methods to achieve the formal aminomethylation of activated unsaturated compounds.

Synthesis, Application and Kinetic Studies of Chiral Phosphite-Oxazoline Palladium Complexes as Active and Selective Catalysts in Intermolecular Heck Reactions

This study identifies new phosphite-oxazoline ligands that have been successfully applied in the palladium-catalyzed intermolecular asymmetric Heck reaction. The design of the new phosphite-oxazoline ligands derives from a previous successful generation of phosphine-oxazoline ligands, by replacing the phosphine group with several pi-acceptor biaryl phosphite moieties. With these simple modifications, the new phosphite-based ligands, unlike previous phosphine-oxazoline, not only present a modular design with numerous potential phosphite groups available, but they are also air-stable solids, which can be made in the same number of synthetic steps as the phosphine analogues. The substitution of the phosphine by a biaryl phosphite group extended the range of substrates and triflates sources that can be coupled with regio-, enantioselectivities and activities comparable to the few best ones reported. In addition, the ligands that provided the best selectivities contained an isopropyl oxazoline moiety instead of the tert-butyl group found in the related phosphine-oxazoline ligands, which is made from a much more expensive precursor. In this paper we have also carried out kinetic studies and a Hammett plot analysis to determine the rate determining step of this system in the regime of interest. We suggest a likely explanation for the fast Heck reaction of the phosphite-oxazoline catalysts. (Figure presented.).

Polymeric dibromomaleimides as extremely efficient disulfide bridging bioconjugation and pegylation agents

A series of dibromomaleimides have been shown to be very efficacious at insertion into peptidic disulfide bonds. This conjugation proceeds with a stoichiometric balance of reagents in buffered solutions in less than 15 min to give discrete products while maintaining the disulfide bridge and thus peptide conformation. The insertion is initiated by disulfide reduction using a water-soluble phosphine, tris(2-carboxyethyl)phosphine (TCEP) which allows for subsequent substitution of the two maleimide bromides by the generated thiols. Reaction of salmon calcitonin (sCT) with 2,3-dibromomaleimide (1.1 excess) in the presence of TCEP (1.1 equiv) in aqueous solution at pH 6.2 gives complete production of a single conjugate which requires no workup. A linear methoxy poly(ethylene glycol) (PEG) was functionalized via a Mitsunobu reaction and used for the successful site-specific and rapid pegylation of sCT. This reaction occurs in 15 min with a small stoichiometry excess of the pegylating agent to give insertion at the disulfide with HPLC showing a single product and MALDI-ToF confirming conjugation. Attempts to use the group in a functional ATRP polymerization initiator led to polymerization inhibition. Thus, in order to prepare a range of functional polymers an indirect route was chosen via both azide and aniline functional initiators which were converted to 2,3-dibromomaleimides via appropriate reactions. For example, the azide functional polymer was reacted via a Huisgen CuAAC click reaction to an alkyne functional 2,3-dibromomaleimide. This new reagent allowed for the synthesis of conjugates of sCT with comb polymers derived from PEG methacrylic monomers which in addition gave appropriate cloud points. This reaction represents a highly efficient polymer conjugation method which circumvents problems of purification which normally arise from having to use large excesses of the conjugate. In addition, the tertiary structure of the peptide is efficiently maintained.
