Protecting-group-free synthesis of the bisindolylmaleimide
The bisindolylmaleimide GF109203X is a highly selective inhibitor to Protein Kinase C (PKC)
and has attracted much attention. However, its reported synthesis required protecting groups. In order to achieve a short and N-protecting-group-free synthesis of GF109203X, an investigation on N-alkylation of arcyriarubin A was carried out using different bases, solvents and equivalents of bromododecane. I...

Thermotropic Liquid Crystals of a Non-Mesogenic Group Bearing
A tri(ethylene oxide)octadecyldimethylammonium p-toluenesulfonate (C18NEO3 3 Ts) amphiphile was employed to encapsulate Keggin-type polyoxometalates by ion metathesis reactions with phosphotungstic acid, silicotungstic acid, pentapotassium dodecatungstoborate(III), and phosphomolybdic acid, giving the surfactant-encapsulated polyoxometalates (SEPs) in SEP-P, SEP-Si, SEP-B, and SEP-PMo, respectivel...

24. Synthesis and characterization of fluorinated polyimide oligomers terminated with a phenylethynyl group
Novel all-aromatic phenylethynyl-terminated imide oligomers were prepared by the reaction of 4,4-oxydiphthalic anhydride (ODPA) or 4,4-(hexafluoroisopropylidene)diphthalic anhydride (6FDA) with 1,4-(4-amino-2-trifluoromethyl-phenoxy)-2-(3''''-trifluoro-methylphenyl) benzene and 4-(1-phenylethynyl)1,8-naphthalic anhydride (PENA). The resulting polymers were thermally crosslinked at 370 degrees C. T...

2. Synthesis and Characterization of Poly(ether ether ketone)s with (2,5‐dihydroxy)phenyl Side Group
A new monomer, (2,5-dimethoxy)phenylhydroquinone (DMPH), was prepared in a two-step synthetic procedure. One aromatic poly(ether ether ketone)s with 2,5-dimethayy phenyl side group (DMP-PEEK) was synthesized via an aromatic nucleophilic substitution reaction with 4,4''''''''-difluorobenzopherone (DFB). Poly(ether ether ketone)s with 2,5-dihydroxy phenyl side group (DHP-PEEK) was obtained via hydro...

Photoreactive Polymers Bearing a Zwitterionic Phosphorylcholine Group for Surface Modification of Biomaterials
Photoreactive polymers bearing zwitterionic phosphorylcholine and benzophenone groups on the side chain were
synthesized and used as surface modification reagents for biomaterials. A photoreactive methacrylate containing the
benzophenone group, 3-methacryloyloxy-2-hydroxypropyl-4-oxybenzophenone (MHPBP), was synthesized via a ring-opening
and addition reaction between glycidyl ...
