Journal ArticleDOI
Isotropic Spectra of Half-Integer Quadrupolar Spins from Bidimensional Magic-Angle Spinning NMR
Lucio Frydman,John S. Harwood +1 more
TL;DR: In contrast to what happens in spin-'/2 spectroscopy, no single-axis spinning techniques are available for canceling the effects of these second-order anisotropies as discussed by the authors.
Journal ArticleDOI
Multiple-Quantum Magic-Angle Spinning NMR: A New Method for the Study of Quadrupolar Nuclei in Solids
TL;DR: In this paper, the authors have shown that the combined use of fast magic-angle spinning and bidimensional multiple-quantum (MQ) spectroscopy can refocus these anisotropies.
Journal ArticleDOI
Dual Targeting of Intracellular Pathogenic Bacteria with a Cleavable Conjugate of Kanamycin and an Antibacterial Cell-Penetrating Peptide
Anna Brezden,Mohamed F. Mohamed,Manish Nepal,John S. Harwood,Jerrin Kuriakose,Mohamed N. Seleem,Jean Chmielewski +6 more
TL;DR: A cleavable conjugate of the antibiotic kanamycin and a nonmembrane lytic, broad-spectrum antimicrobial peptide with efficient mammalian cell penetration, P14LRR, was prepared and effectively cleared intracellular pathogenic bacteria within macrophages more potently than that of a conjugates lacking the disulfide moiety.
Journal ArticleDOI
Crystallization and textural porosity of synthetic clay minerals
Kathleen A. Carrado,Roseann Csencsits,Pappannan Thiyagarajan,Soenke Seifert,Susan M. Macha,John S. Harwood +5 more
TL;DR: In this article, the authors compared the crystallization of synthetic layered magnesium silicate hectorite clays from both silica sol and organosilane sources, and compared the pore size distributions based on both the adsorption and desorption isotherms.
Journal ArticleDOI
Regiocontrolled synthesis and HIV inhibitory activity of unsymmetrical binaphthoquinone and trimeric naphthoquinone derivatives of conocurvone.
Kenneth W. Stagliano,Ashkan Emadi,Zhenhai Lu,Helena C. Malinakova,Barry Twenter,Min Yu,Louis E. Holland,Amanda M. Rom,John S. Harwood,Ronak Amin,Allison A. Johnson,Yves Pommier +11 more
TL;DR: Unsymmetrical biquinone and trimeric quinone derivatives were synthesized using halotriflate-biselectrophilic naphthoquinones through stepwise regioselective quin one substitution chemistry and evaluated for their ability to inhibit the cytopathogenic effects of HIV-1 using an MTT colorimetric assay.
