Crystalline complexes of S-tert-butylisothiuronium perchlorate ( t-BuSC(NH2),C104) and 18-crown-6 (18C6) and 1,3-xylyl-18-crown-5 (1,3X18C5) with a 1:l stoichiometry were obtained via extraction. X-ray diffraction analysis showed that in the solid state the guest molecule is coordinated via one of the two NH, groups to the crown ether. The second NH2 group is bound to the anion. 'H NMR spectros...
Reactions of silver(I) salts with 4-amino-4H-1,2,4-triazole (4-NH2-tz) in a 1 : 1 molar ratio yield four new silver adducts, namely [Ag(4-NH2-tz)](CF3SO3) (1), [Ag(4-NH2-tz)1.75](ClO4) (2), [Ag(4NH2-tz)1.75](BF4) (3) and [Ag(4-NH2-tz)1.75](NO3) (4). X-Ray analysis shows that 1 exhibits a 3D cationic [Ag(4-NH2-tz)] metal-organic framework of srs topology; 2, 3 and 4 are isostructural and display...
A novel synthetic hexapeptide (SFKLRY-NH2) that displays angiogenic activity has been identified by positional scanning of a synthetic peptide combinatorial library (PS-SPCL). This study was carried out to investigate the irritation of the SFKLRY-NH2 on the skin. The tests were performed on the basis of Korea Food and Drug Administration (KFDA) guidelines. In results, cell toxicity is not appea...
Defensin from a beetle, Allomyrina dichotoma, is known to have anti-bacterial activity against Gram-positive bacteria. This peptide, which comprises 43 amino acid residues, was effective against methicillin-resistant Staphylococcus aureus. We identified the active site of beetle defensin by measuring anti-bacterial activity against S. aureus of 64 overlapping 12-mer peptides with either a free ...
8-Aminoadenosine (8-NH2-Ado), a ribosyl nucleoside analog, in preclinical models of multiple myeloma inhibits phosphorylation of proteins in multiple growth and survival pathways, including Akt. Given that Akt controls the activity of mammalian target of rapamycin (mTOR), we hypothesized that 8-NH2-Ado would be active in mantle cell lymphoma (MCL), a hematological malignancy clinically responsi...
Physiologically stable multimodality imaging probes for positron emission tomography/single-photon emission computed tomography (PET/SPECT)-magnetic resonance imaging (MRI) were synthesized using the superparamagnetic maghemite iron oxide (γ-Fe2O3) nanoparticles (SPIONs). The SPIONs were sterically stabilized with a finely tuned mixture of diblock copolymers with either methoxypolyethylene glyc...
Bio-chemical reduction method was employed to synthesise the silver nanoparticles (Ag NPs) by aging the mixture of the aqueous extract of the Trachyspermum Ammi (TA, Ajwain) seeds and AgNO3 solution at different time interval. Reaction time of AgNO3 and TA could accelerate the reduction rate of Ag and affect AgNPs size and concentration of NPs. X-ray diffraction (XRD) studies confirms the forma...
در این پژوهش، اثر چارچوب های فلزی-آلی nh2-mil 53 بر خواص گازتراوایی غشای پلیمری پلی(4- متیل-1- پنتین) (pmp) بررسی شده است. از روش های مختلفی نظیر ftir، dsc، sem و آزمون جذب گاز به همراه آزمون جداسازی co2/ch4 به حالت گاز خالص و مخلوط گازی برای بررسی آثار گروه عاملی nh2- بر خواص غشاهای شبکه ترکیبی بهره گرفته شد. نتایج حاصل از dsc نشان دهنده افزایش دمای انتقال شیشه ای (tg) غشاها به ازای ازدیا...
Polyvinylcaprolactam (PVCap) is an economic kinetic inhibitor for hydrate formation in pipelines during oil and gas transportation. However, its application limited because of the low inhibition performance under certain conditions. In this work, a modified PVCap on chain end proposed. 2-amino-3-propionic acid mercapto-terminated polyvinyl caprolactam (PVCap-NH2-COOH) was synthesized as KHI met...
The cysteine anion was produced in the gas phase by electrospray ionization and investigated by photoelectron spectroscopy at low temperature (70 K). The cysteine anion was found to exhibit the thiolate form [-SCH2CH(NH2)CO2H], rather than the expected carboxylate form [HSCH2CH(NH2)CO2-]. This observation was confirmed by two control experiments, that is, methyl cysteine [CH3SCH2CH(NH2)CO2-] an...
