Synthesis of the Tetraketide Lactones from the Pikromycin Biosynthetic Pathway
(WILEY-VCH Verlag, 2007-07)
Synthesis of tetraketide lactones 2 and 3 , which are likely to be produced by a model pikromycin polyketide synthase (PKS), has been investigated. The tetraketide lactones with six-membered rings, 2a and 2b , were ...
Site‐Specific Fluorescent Labeling of Large RNAs with Pyrene
(Oxford University PressWiley Periodicals, Inc., 2004-12)
Pyrene is a useful chromophore for monitoring the tertiary structure and folding of large RNAs. This unit describes the general preparation of a large RNA (>80 nucleotides in length) that has been site‐specifically modified ...
Preparation of 2′‐O‐[(Triisopropylsilyl)oxy]methyl‐protected Ribonucleosides
(Oxford University PressWiley Periodicals, Inc., 2001-12)
The [(triisopropylsilyl)oxy]methyl (TOM) group is a useful protecting group for the 2′‐OH of ribonucleosides to be used for oligoribonucleotide synthesis by the phosphoramidite method. It is completely stable to all reaction ...
A study of a C Α, Β -didehydroalanine homo-oligopeptide series in the solid-state by 13 C cross-polarization magic angle spinning NMR
(John Wiley & Sons, Ltd., 2004-06)
The fully extended peptide conformation (2.0 5 -helix) has been investigated for the first time in the solid-state by 13 C cross-polarization magic angle spinning NMR. The compounds examined are members of a terminally ...
Synthesis of Phosphorothioate Oligonucleotides with Stereodefined Phosphorothioate Linkages
(Wiley‐Liss, 2003-09)
A method for solid‐phase synthesis of stereodefined PS‐oligos via an oxathiaphospholane approach using pure P‐diastereomers of nucleoside oxathiaphospholane monomers is described. The oxathiaphospholane monomers are ...
Chemotherapy for prostate cancer: implementing early systemic therapy to improve outcomes
(Springer-Verlag, 2005-11)
Prostate cancer remains a significant health concern for men in the USA as it is a leading cancer diagnosis and a cause of death. With the use of prostate-specific antigen or screening, a stage migration has occurred with ...
New unsymmetrical μ -phenoxo bridged binuclear copper(II) complexes
(Kluwer Academic Publishers; Springer Science+Business Media, 2003-05)
A series of binuclear Cu II complexes [Cu 2 XL] n + having two copper(II) ions bridged by different motifs (X = OH − , MeCO 2 − , or Cl − ) have been prepared using the ligands: H 2 L 1 = 4-methyl-2-[ N -(2-{dimethylamino}ethyl- ...
Protection of 5′‐Hydroxy Functions of Nucleosides
(IRL PressWiley Periodicals, Inc., 2000-02)
The 5‐hydroxy group is the primary hydroxy group of nucleosides. It is mandatory to protect 5‐hydroxyls in all methods of oligonucleotide synthesis that require nucleoside synthons. This unit discusses a wide variety of ...
Proteomic analysis of cold adaptation in a Siberian permafrost bacterium – Exiguobacterium sibiricum 255–15 by two-dimensional liquid separation coupled with mass spectrometry
(WILEY-VCH Verlag, 2006-10)
Bacterial cold adaptation in Exiguobacterium sibiricum 255–15 was studied on a proteomic scale using a 2-D liquid phase separation coupled with MS technology. Whole-cell lysates of E. sibiricum 255–15 grown at 4°C and ...
