Bacterial base excision repair enzyme Fpg recognizes bulky N7-substituted-FapydG lesion via unproductive binding mode
(2012-07-18)
Fpg is a bacterial base excision repair enzyme that removes oxidized purines from DNA. This work shows that Fpg and its eukaryote homolog Ogg1 recognize with high affinity FapydG and bulky N7-benzyl-FapydG (Bz-FapydG). The ...
Convergent, stereoselective syntheses of the glycosidase inhibitors broussonetines C, O and P
(Elsevier, 2009)
The first syntheses of the polyhydroxylated alkaloids (iminosugars) broussonetines O and P, glycosidase inhibitors of the pyrrolidine class, have been performed in a convergent, stereocontrolled way from d-serine as the ...
Malayaite ceramic pigments: A combined optical spectroscopy and neutron/X-ray diffraction study
(Elsevier, 2009)
Ceramic pigments based on the Cr-doped malayaite structure were synthesized by solid state reaction and characterized by optical spectroscopy and combined X-ray and neutron powder diffraction in order to elucidate the still ...
Cu2ZnSnS4 films deposited by a soft-chemistry method
(Elsevier, 2009)
Cu2ZnSnS4 films were deposited on glass substrates by the use of a printing technique. A series of different precursor materials was synthesized by a soft-chemistry route. Suspensions were prepared with or without the ...
Synthesis of new chiral imidazolium salts derived from amino acids: their evaluation in chiral molecular recognition
(Elsevier, 2009)
A family of new imidazolium salts derived from natural amino acids has been synthesized and tested for NMR enantiodiscrimination, as chiral shift reagents, of carboxylic acids. These imidazolium receptors contain different ...
Stereoselective syntheses of the glycosidase inhibitors hyacinthacine A2, hyacinthacine A3 and 5-epi-hyacinthacine A3
(Elsevier, 2009)
Stereoselective syntheses of the naturally occurring glycosidase inhibitors hyacinthacines A2 and A3 are reported. In the case of hyacinthacine A2, the pyrrolizidine system was created from an acyclic precursor via a double ...
Stereoselective synthesis of the cytotoxic macrolide aspergillide B
(Elsevier, 2009)
A total, stereoselective synthesis of the cytotoxic macrolide aspergillide B has been performed. A cross metathesis and a C-glycosidation via a Mukaiyama-type aldol reaction were key features of the synthesis. The macrocyclic ...

Amidation through carbamates
(Elsevier, 2009)
N-Alkyl carbamates of primary amines are easily converted into amides under treatment with Grignard reagents. Consequently, primary amines can be converted into amides in a one-pot reaction through carbamate protection and ...
Structural Features of Mono- and Dimetallic Complexes of Palladium Combining Two Types of Aromatic NHC Ligands
(ChemPubSoc Europe, 2019-09-08)
A family of palladium complexes that combine two types of aromatic N‐heterocyclic carbene (NHC) ligands has been prepared starting from dinuclear palladium complexes. Two of the complexes are mono‐metallic and contain a ...
