Cobalt-catalyzed, directed arylation of C-H bonds in -aryl pyrazoles.

We report a method for directed -arylation of -aryl pyrazoles with arylboronic acids. Reactions proceeded in the presence of a Co(hfacac) catalyst, CeSO oxidant, and HFIP solvent. Functionalities such as nitro, ester, bromo, and ketone groups were compatible with the reaction conditions.

The herbal medicine Cyperus amuricus inhibits proliferation of human hepatocellular carcinoma Hep3B cells by inducing apoptosis and arrest at the G0/G1 cell cycle phase.

Cyperus amuricus (C. amuricus) is one of the most common herbs in Oriental folk medicine for exerting astringent, diuretic, wound healing and other intestinal problems. However, little is known about the molecular mechanism of C.

Synthesis and characterization of hydroxyapatite-ciprofloxacin delivery systems by precipitation and spray drying technique.

This investigation synthesized and characterized hydroxyapatite (HAP) microspheres, agglomerated microspheres, and implants containing ciprofloxacin. This delivery system is to be used as an implantable drug delivery system for the treatment of bone infections. The HAP microspheres were made by chemical precipitation followed by a spray-drying technique.
