BACKGROUND There is a clinical need for new therapeutic products against Herpes simplex virus (HSV). The pomegranate, fruit of the tree Punica granatum L, has since ancient times been linked to activity against infection. This work probed the activity of pomegranate rind extract (PRE) and co-administered zinc (II) ions. MATERIALS AND METHODS PRE was used in conjunction with zinc (II) salts to...

Zinc is an essential element required for the function of more than 300 enzymes spanning all classes. Despite years of dedicated study, questions regarding the connections between primary and secondary metal ligands and protein structure and function remain unanswered, despite numerous mechanistic, structural, biochemical, and synthetic model studies. Protein design is a powerful strategy for r...

A system for detecting the effects of metal ions, repressors, and mutations on the biosynthesis in vivo of alkaline phosphatase of Escherichia coli is described. If E. coli constitutive for alkaline phosphatase are grown in a medium containing 65Zn and are subject to osmotic shock, about 50% of the zinc taken up by the cells is released into the medium. Chromatography of this medium shows that ...

the zinc(ii) complex [zn2(dmdtc)2(μ-dmdtc)2] has been synthesized directly from thiram ligand, containing a disulfide bond {dmdtc = n,n-dimethyldithiocarbamate; thiram = n,n-tetramethylthiuram disulfide}, and characterized by elemental analysis and spectroscopic methods. surprisingly thiram, undergoes a reductive disulfide bond scission upon reaction with zn2+ in methanolic media to give the [z...
