Influenza virus PA endonuclease has recently emerged as an attractive target for the development of novel antiviral therapeutics. This is an enzyme with divalent metal ion(s) (Mg(2+) or Mn(2+)) in its catalytic site: chelation of these metal cofactors is an attractive strategy to inhibit enzymatic activity. Here we report the activity of a series of N-acylhydrazones in an enzymatic assay with P...

A flow injection spectrophotometric method for the assay of ciprofloxacin was developed. The method was based on the chelation of iron(III) with the drug in 0.023 mol dm-3 sulfuric acid solution in a 72 cm long coil and the brown-red complex produced was monitored at 447 nm. The super modified simplex computer program was employed for the optimization of the system and chemical parameters with ...

Using a new assay for membrane fusion between late Golgi/endosomal compartments, we have reconstituted a rapid, robust homotypic fusion reaction between membranes containing Kex2p and Ste13p, two enzymes resident in the yeast trans-Golgi network (TGN). Fusion was temperature, ATP, and cytosol dependent. It was inhibited by dilution, Ca+2 chelation, N-ethylmaleimide, and detergent. Coimmunoisola...

Valeriana jatamansi is an indigenous medicinal plant used in the treatment of a number of diseases. In the present study, chemical composition of the essential oil was determined by GC-MS. Seven major components were identified in Valeriana jatamansi essential oil, namely, β-vatirenene, β-patchoulene, dehydroaromadendrene, β-gurjunene, patchoulic alcohol, β-guaiene, and α-muurolene. Methanolic,...

Background Regular transfusion in thalassemia major patients increases life expectancy and improves quality of life, but results in iron overload, which had toxic effects to organs including endocrine glands. The introduction of iron chelation therapy has reduced its toxicity, but complications may still occur. In Indonesia, most of our patients did not receive optimal iron chelation therapy, w...

1,2-Dithiooxalate (dto) can be employed as a bridging ligand and gives symmetric ( O , S -chelation) or asymmetric - coordination modes. In this study, we have prepared novel dto-bridged diiron(II)...
