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.

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.

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.

Determination of selected isoquinoline alkaloids from mahonia aquifolia; Meconopsis cambrica; Corydalis lutea; Dicentra spectabilis; Fumaria officinalis; Macleaya cordata Extracts by HPLC-DAD and Comparison of Their Cytotoxic Activity

Alkaloids have protective functions for plants and can play an important role in living organisms. Alkaloids may have a wide range of pharmacological activities. Many of them have cytotoxic activity. Nowadays, cancer has become a serious public health problem. Searching for effective drugs with anticancer activity is one of the most significant challenges of modern scientific research. The aim of this study was the investigation of cytotoxic activity of extracts obtained from Corydalis lutea root and herb, Dicentra spectabilis root and herb, Fumaria officinalis, Macleaya cordata leaves and herb, Mahonia aquifolia leaves and cortex, Meconopsis cambrica root and herb on FaDu, SCC-25, MCF-7, and MDA-MB-231 cancer cell lines. The cytotoxic activity of these extracts has not been previously tested for these cell lines. The aim was also to quantify selected alkaloids in the investigated extracts by High Performance Liquid Chromatography (HPLC). The analyses of alkaloid content were performed using HPLC in reversed phase (RP) mode using Polar RP column and mobile phase containing acetonitrile, water and ionic liquid (IL). Cytotoxic effect of the tested plant extracts and respective alkaloid standards were examined using human pharyngeal squamous carcinoma cells (FaDu), human tongue squamous carcinoma cells (SCC-25), human breast adenocarcinoma cell line (MCF-7), human triple-negative breast adenocarcinoma cell line (MDA-MB-231). All investigated plant extracts possess cytotoxic activity against tested cancer cell lines: FaDu, SCC-25, MCF-7, and MDA-MB-231. The highest cytotoxic activity against FaDu, SCC-25, and MCF-7 cell lines was estimated for Macleaya cordata leaf extract, while the highest cytotoxic activity against MDA-MB-231 cell line was obtained for Macleaya cordata herb extract. Differences in cytotoxic activity were observed for extracts obtained from various parts of investigated plants. In almost all cases the cytotoxic activity of investigated plant extracts, especially at the highest concentration against tested cell lines was significantly higher than the activity of anticancer drug etoposide. Our investigations exhibit that these plant extracts can be recommended for further in vivo experiments to confirm their anticancer activity.

Efficient and general protocol for Sonogashira cross-coupling reactions of maleimides

Maleimides are involved for the first time in Sonogashira cross-coupling reactions. Sonogashira conditions have been developed to allow subsequent coupling of various terminal alkynes at room temperature in moderate to excellent yields. These results open the way to innovative synthesis strategies for various difunctionalized maleimide derivatives. The reactivity of maleimides in Sonogashira cross-coupling reactions was studied. The important role of the base is demonstrated, and optimized experimental conditions are described with a large variety of alkynes. The reactivity of the alkynes is also discussed. This reaction provides rapid access to a wide range of new maleimide derivatives in moderate to excellent yields. Copyright
