Alternate injections coupled with flow-gated capillary electrophoresis for rapid and accurate quantitative analysis of urine samples
(Elsevier B.V., 2017-07-25)Capillary electrophoresis (CE) is a powerful separation technique with advantages over HPLC in terms of separation efficiency, speed, and cost. However, CE suffers in poor reproducibility in quantitative chemical analysis, ... -
Amino acid-derived 1,2-benzisothiazolinone derivatives as novel small-molecule antifungal inhibitors: identification of potential genetic targets
(American Society of Microbiology, 2012-09)We have identified four synthetic compounds (DFD-VI-15, BD-I-186, DFD-V-49, and DFD-V-66) from an amino acid-derived 1,2-benzisothiazolinone (BZT) scaffold that have reasonable MIC50 values against a panel of fungal ... -
Amino acid-derived phthalimide and saccharin derivatives as inhibitors of human leukocyte elastase, cathepsin G, and proteinase 3
(Elsevier, 1996-08-15)Amino acid-derived phthalimide and saccharin derivatives have been investigated for their inhibitory activity toward the serine proteinases human leukocyte elastase, cathepsin G, and proteinase 3. The saccharin derivatives ... -
Anion-complexation-induced stabilization of charge separation
(American Chemical Society, 2009-11-11)A supramolecular oligochromophoric system possessing exclusive binding sites for both a guest electron acceptor and an anionic cofactor species is developed, and anion-binding-induced stabilization of the charge-separated ... -
Anthrax toxin protective antigenuInsights into molecular switching from prepore to pore
(Cambridge University Press, 2012-01)The protective antigen is a key component of the anthrax toxin, as it allows entry of the enzymatic components edema factor and lethal factor into the host cell, through the formation of a membrane spanning pore. This event ... -
Anti-norovirus therapeutics: a patent review (2010-2015)
(Taylor & Francis Group, 2016-03-03)Introduction: Human noroviruses are the primary causative agents of acute gastroenteritis and are a pressing public health burden worldwide. There are currently no vaccines or small molecule therapeutics available for the ... -
Antifungal activity of a series of 1,2-benzisothiazol-3(2H)-one derivatives
(Elsevier, 2011-10-01)A series of broad-spectrum antifungal agents based on the 1,2-benzisothiazol-3(2H)-one scaffold is reported. Preliminary structure-activity relationship studies have established the importance of the presence of the ... -
Antifungal drug discovery: the process and outcomes
(Future Medicine Ltd, 2014-06)New data suggest that the global incidence of several types of fungal diseases have traditionally been under- documented. Of these, mortality caused by invasive fungal infections remains disturbingly high, equal to or ... -
Antiviral drug discovery: norovirus proteases and development of inhibitors
(MDPI AG, Basel, Switzerland, 2019-02-25)Proteases are a major enzyme group playing important roles in a wide variety of biological processes in life forms ranging from viruses to mammalians. The aberrant activity of proteases can lead to various diseases; ... -
Apparent inhibition by arginine of macrocyclic b ion formation from singly charged protonated peptides
(Springer, 2010-08-01)There is now strong evidence for the existence of macrocyclic isomers of b(n)(+) ions, the formation and subsequent opening of which can lead to loss of sequence information from protonated peptides in multiple-stage tandem ... -
Application of spherical and other polymers in capillary zone electrophoresis: separation of antiviral drugs and deoxyribonucleoside phosphates by different principles
(Elsevier, 1996-12-20)Soluble polymers of linear chains with limited branching and spherical polymers (limit dextrins and sucrose, such as Dextran and Ficoll (Pharmacia Chemicals), yielding lower viscosities, are examined here for the separation ... -
Applying band gap engineering to tune the linear optical and nonlinear optical properties of noncentrosymmetric chalcogenides $La_4Ge_3Se_X S_{12- x} (x = 0, 2, 4, 6, 8, 10)$
(Royal Society of Chemistry, 2021-09-10)$La_4Ge_3S_{12}$ was structurally characterized in 1974 without any optical or nonlinear optical properties reported. Herein we report that the acentric crystal structure of $La_4Ge_3S_{12}$ has been confirmed by single-crystal ... -
Ascorbate based novel high affinity alternate reductants and competitive inhibitors of dopamine beta-monooxygenase
(Elsevier, 1994-04-15)A series of ascorbate derivatives has been used to examine the specificity and the chemistry of the reduction site of dopamine beta-monooxygenase (D beta M). Replacement of the 6-OH group of ascorbic acid with either bromine ... -
Assessing the dipole moments and directional cross sections of proteins and complexes by differential ion mobility spectrometry
(American Chemical Society, 2022-05-02)Ion mobility spectrometry (IMS) has become a mainstream approach to fractionate complex mixtures, separate isomers, and assign the molecular geometries. All modalities were grouped into linear IMS (based on the absolute ... -
