Tetraarylpyrroles with a 1-azulenyl substituent were prepared by the reaction of 1-azulenyl ketones, which have various aryl-substituents at their α-position, with benzoin in the presence of ammonium acetate as a nitrogen source of the pyrrole ring. Optical property of the tetraarylpyrroles obtained by the reaction was clarified by UV/Vis spectroscopy and/or time-dependent density functional th...

Previous studies on isolated thyroid cell membranes (1) revealed the presence of an adenosinr triphosphatase (ATPase) activity in these membranes nhicsh showed features characteristic of Na+ and K+ transport by intact cells, and which was enhanced by thyrotropin (TSH’). This ATPase activity was stimulated by Na+ and K+ and required both ions together, was inhibited by ouabain, was Mg++-requirin...

BACKGROUND If literature protocols are followed, conversion of an advanced ketal ester intermediate (available in kilogram quantities via a published Paal-Knorr synthesis) to cholesterol-lowering drug atorvastatin calcium is hampered by several process issues, particularly at the final stage where the hemi-calcium salt is obtained. RESULTS We developed a high-yielding synthesis of atorvastati...

It was experimentally observed that the majority of real-world networks are scale-free and follow power law degree distribution. The aim of this paper is to study the algorithmic complexity of such “typical” networks. The contribution of this work is twofold. First, we define a deterministic condition for checking whether a graph has a power law degree distribution and experimentally validate i...
