روش های معمول برای تهیه بنزوتیازول ها شامل تراکم 2-آمینوتیوفنول با کربوکسیلیک اسید ها، آلدهید ها و هم¬چنین ارتواسترها می باشد. در این کار، کاتالیست nano- γ-al2o3/bf3-n به عنوان کاتالیست اسید جامد تهیه شده است. برای تایید ساختار nano- γ-al2o3 و nano- γ-al2o3/bf3-n طیف مادون قرمز و پراش پرتو xگرفته شده است. مشتقهای بنزوتیازول از طریق تراکم آلدهید ها با 2-آمینوتیوفنول با استفاده از nano- γ-al2o...
In this Article, there is an error in the labelling of the western blot in Fig. 3f. The labels indicating the presence of pterosin B in each lane should read ' À þ þ þ '. The correct version of Fig. 3 appears below.
BACKGROUND Pseudoxanthoma elasticum (PXE) is a hereditary connective tissue disease in which proteoglycans have altered properties. We investigated whether altered proteoglycan metabolism occurs in vivo and may be reflected in the urine of PXE individuals by analyzing the excreted polysaccharides. METHODS We measured sulfated glycosaminoglycans in the urine of 10 PXE-affected patients, 12 hea...
OBJECTIVES/HYPOTHESIS To localize quantitatively the major biochemical constituents of native adult human septal cartilage across whole septa. STUDY DESIGN Prospective, basic science. METHODS The nasal septa from seven cadavers were partitioned into 24 separate regions: six from caudal to cephalic and four from dorsal to ventral. Biochemical assays were used to determine the quantities, rel...
Circumsporozoite (CS) proteins, which densely coat malaria (Plasmodia) sporozoites, contain an amino acid sequence that is homologous to segments in other proteins which bind specifically to sulfated glycoconjugates. The presence of this homology suggests that sporozoites and CS proteins may also bind sulfated glycoconjugates. To test this hypothesis, recombinant P. yoelii CS protein was examin...
Sulfated polysaccharides from Laminaria saccharina (new name: Saccharina latissima) brown seaweed show promising activity for the treatment of inflammation, thrombosis, and cancer; yet the molecular mechanisms underlying these properties remain poorly understood. The aim of this work was to characterize, using in vitro and in vivo strategies, the anti-inflammatory, anti-coagulant, anti-angiogen...
Sulfated molecules have been shown to modulate isotypic interactions between cells of metazoans and heterotypic interactions between bacterial pathogens or symbionts and their eukaryotic host cells. Mycobacterium tuberculosis, the causative agent of tuberculosis, produces sulfated molecules that have eluded functional characterization for decades. We demonstrate here that a previously uncharact...
The presence of sulfated polysaccharides in cell walls of seaweeds is considered to be a consequence of the physiological adaptation to the high salinity of the marine environment. Recently, it was found that sulfated polysaccharides were present in certain freshwater Cladophora species and some vascular plants. Cladophora (Ulvophyceae, Chlorophyta) is one of the largest genera of green algae t...
