Highly selective antiplasmodial naphthylisoquinoline alkaloids from Ancistrocladus tectorius.
Naphthylisoquinoline alkaloids, named ancistectorine A1, N-methylancistectorine A1, ancistectorine A2, 5-epi-ancistectorine A2, ancistectorine A3, ancistectorine B1, and ancistectorine C1, have been… Expand
Bilirubin removal by Cibacron Blue F3GA attached nylon-based hydrophilic affinity membrane
Covalent coupling of chitosan to the activated membrane was performed after the reaction of the microporous nylon membrane with formaldehyde. Covalent linkage of chitosan was essential to improve the… Expand
Jozimine A2: the first dimeric Dioncophyllaceae-type naphthylisoquinoline alkaloid, with three chiral axes and high antiplasmodial activity.
A new dimeric naphthylisoquinoline alkaloid, jozimine A(2) (2), was isolated from the root bark of an Ancistrocladus species from the Democratic Republic of Congo. Its absolute stereostructure was… Expand
Organic-acid-directed assembly of iron–carbon oxides nanoparticles on coordinatively unsaturated metal sites of MIL-101 for green photochemical oxidation
Through a simple organic-acid-directed approach, in situ growth of iron–carbon oxide nanoparticles (NPs) were assembled on the coordinatively unsaturated Cr sites (CUSs) of MIL-101 and inserted into… Expand
Cyclodysidins A–D, cyclic lipopeptides from the marine sponge-derived Streptomyces strain RV15
Four new cyclic lipopeptides, cyclo-(AFA-Ser-Gln-Asn-Tyr-Asn-Ser-Thr), named cyclodysidins A–D, were isolated from the broth culture of Streptomyces strain RV15 associated with the marine sponge… Expand
l-proline covalently anchored on graphene oxide as an effective bifunctional catalyst for ketene forming reaction
Abstract Graphene oxide supported l -proline (GO–Proline) bifunctional catalyst was prepared by covalent bonds via a succinate spacer. Fourier transform infrared spectrum (FTIR), Raman spectroscopy,… Expand
Efficient Near-Infrared-Emitting Cationic Iridium Complexes as Dopants for OLEDs with Small Efficiency Roll-off
Two near-infrared- (NIR-) emitting cationic iridium(III) complexes, [Ir(pbq-g)2(Bphen)]+PF6– (1) and [Ir(mpbqx-g)2(Bphen)]+PF6– (2), were synthesized and characterized, where pbq-g, mpbqx-g, and… Expand
Ancistectorine D, a naphthylisoquinoline alkaloid with antiprotozoal and antileukemic activities, and further 5,8'- and 7,1'-linked metabolites from the Chinese liana Ancistrocladus tectorius.
From the twigs and stems of the Chinese liana Ancistrocladus tectorius (Ancistrocladaceae), two new 5,8'-coupled naphthylisoquinolines, ancistectorine D (5) and its 6-O-demethyl derivative 6, were… Expand
Coating and filling of carbon nanotubes with homogeneous magnetic nanoparticles
Magnetic multi-walled carbon nanotube (MWCNT) composites were obtained by decoration of metal oxide nanoparticles on or in carbon nanotubes. The method involved the dispersion of the carbon nanotubes… Expand
Chemical modification of polysulfone membrane by polyethylene glycol for resisting drug adsorption a
Abstract Both hemocompatibility and cytocompatibility of biomaterials are the prerequisite for the application in tissue engineering. Although polyethylene glycol (PEG) has attracted considerable… Expand
