The reaction of N-heterocyclic carbene (NHC) with dimeric dialkylgallium alkoxides, acting as nonselective or heteroselective catalysts in the polymerization of rac-LA, leads to highly active and isoselective monomeric Me(2)Ga(NHC)OR catalysts, resulting for the first time in the fac...

Epidermal growth factor receptors (EGFR) are over-expressed in many different types of cancer, thus, are logical targets for both diagnosis and therapy. Antibodies and antibody fragments targeting the extracellular EGF receptor and small molecules targeting the intracellular tyrosine...

The safety and efficacy of hematopoietic stem cell (HSC) mobilization was investigated in adult splenectomized (SPL) and non-SPL patients with thalassemia major, in two clinical trials, using different mobilization modes: granulocyte-colony-stimulating factor (G-CSF)-alone, G-CSF fol...

The aim of this work is to design and test an MRI probe (Gd-DOTAtyr-gal) able to report on the gene expression of β-galactosidase (β-Gal) in melanoma cells. The probe consists of a Gd-DOTA reporter bearing on its surface a tyrosine-galactose-pyranose functionality that, upon the re...

Iron(III) salts catalyze the tandem rearrangement/hetero-Diels-Alder reaction of 2H-chromenes to yield tetrahydrochromeno heterocycles. The process can occur as a homodimerization and cycloaddition process using electron-rich dienophiles. Deuterium labeling and mechanistic studies re...

A mild, chemoselective, and generally high-yielding method for the reductive scission of heterocyclic thioethers is described. Suitable heterocycles have a thioether substituent at the 2-position relative to a ring heteroatom. The convenient and straightforward method is demonstrated...

The synthesis and binding properties of a tetrathiafulvalene (TTF)-calix[4]pyrrole receptor 2 appended with one 3,5-dinitrobenzoate guest moiety are reported. The preliminary studies revealed that the receptor is self-complexing into a dimer receptor 2•2. The self-complexation of t...

We investigated the effects of plerixafor (0.04 to 0.24 mg/kg) administered at 2-4 day intervals in 6 patients. Outcome measures were the patients' complete blood cell counts, CD34(+) cell counts and lymphocyte subtypes compared with 5 normal subjects similarly treated with plerixafor. All patients...

N-Heterocyclic carbene catalyzed aza-Claisen annulations of enals or their α'-hydroxyenone surrogates with vinylogous amides afford dihydropyridinones. The reaction proceeds with a broad range of substrates, and no nitrogen protecting group is required. © 2011 Ameri...
