8β-Hydroxy-9(11),13-abietadien-12-one (1), an abietane diterpenoid and aryl hydrocarbon receptor (AhR) ligand, was synthesized in six steps from commercially available (+)-dehydroabietylamine (2). We used the hypervalent iodine catalyst phenyliodine dicarboxylate, a safer alternative to toxic organoselenide reagents, for oxidative dearomatization of ferruginol (7) compound 1. Compounds 1 2, as ...

We systematically investigate the effects of divalent anions on the assembly of polyelectrolyte multilayers by fabricating polystyrene sulfonate (PSS)/polyallylamine hydrochloride (PAH) multilayer films from aqueous solutions containing SO(4)(2-), HPO(4)(2-), or organic dicarboxylate dianions. The chosen concentrations of these anions (i.e., ≤0.05 M) allow us to isolate their effects on the ass...

Hering-Smith, Kathleen S., Cecilia T. Gambala, and L. Lee Hamm. Citrate and succinate transport in proximal tubule cells. Am. J. Physiol. Renal Physiol. 278: F492–F498, 2000.—Urinary citrate, which inhibits calcium nephrolithiasis, is determined by proximal reabsorption via an apical dicarboxylate transporter. Citrate is predominantly trivalent at physiological pH, but citrate22 is transported ...

Single molecule precursors can help to simplify the synthesis of complex alloys by minimizing the amount of necessary starting reagents. However, single molecule precursors are time consuming to prepare with very few being commercially available. In this study, a simple precipitation method is used to prepare Fe, Co, and Ni fumarate and succinate complexes. These complexes were then thermally d...

In the complex (bispyridine -2 and 6-dicarboxylate copper II)) at position H number 26 with modifications of ligands such as vinyl, acetylene and isopropyl, changes in the valance / charge ratio for oxygen and carbon atoms in these complexes have been investigated by methods Initial calculations (ab initio) have been performed at two levels of HF, DFT. Finally, their stability is compared with ...
