Ultrasound- and Molecular Sieves-Assisted Synthesis, Molecular Docking and Antifungal Evaluation of 5-(4-(Benzyloxy)-substituted phenyl)-3- ((phenylamino)methyl)-1,3,4-oxadiazole-2(3H)-thiones
(MPDI, 2016-05-10)
A novel series of 5-(4-(benzyloxy)substituted phenyl)-3-((phenyl amino)methyl)-1,3,4-oxadiazole-2(3H)-thione Mannich bases 6a–o were synthesized in good yield from the key compound 5 (4(benzyloxy)phenyl)-1,3,4-oxadiazole ...
Self-assembling molecular capsules based on alpha, gamma-Cyclic peptides
(American Chemical Society, 2016-12-20)
A new capsule based on a β-sheet self-assembling cyclic peptide with the ability to recognize and release several guests is described. The host structure is composed of two self-complementary α,γ-cyclic peptides bearing a ...
Towards taxane analogues synthesis by dienyne ring closing metathesis
(Royal Society of Chemistry, 2016-10-01)
Herein we report the facile construction of taxadiene analogues by ring closing metathesis of dienynes built on a cyclohexenone with a natural configuration at C1 and its further transformation to incorporate most of the ...
Recent Advances in Controlling the Internal and External Properties of Self‐Assembling Cyclic Peptide Nanotubes and Dimers
(Royal Society of Chemistry, 2017-06-07)
One of the most powerful strategies for the preparation of nanotubes is based on the stacking of flat-shaped cyclic peptide components. This strategy allows precise control of the nanotube internal diameter, the external ...
Self‐assembling Venturi‐like peptide nanotubes
(Royal Society of Chemistry, 2017-01-14)
We describe the design and synthesis of self-assembling peptide nanotubes that have an internal filter area and whose length and internal diameters, at the entrance and in the constricted area, are precisely controlled
Inhibition of Shikimate Kinase and Type II Dehydroquinase for Antibiotic Discovery: Structure-Based Design and Simulation Studies
(Bentham Science, 2016)
The loss of effectiveness of current antibiotics caused by the development of drug resistance has become a severe threat to public health. Current widely used antibiotics are surprisingly targeted at a few bacterial functions ...
Nickel-Catalyzed Intramolecular [3 + 2 + 2] Cycloadditions of Alkylidenecyclopropanes. A Straightforward Entry to Fused 6,7,5- Tricyclic Systems
(American Chemical Society, 2014-09-18)
A highly diastereo- and chemoselective intramolecular nickel-catalyzed cycloaddition of alkene- and alkyne-tethered alkynylidenecyclopropanes is reported. The method constitutes the first fully intramolecular [3 + 2 + 2] ...
Selective DNA-Binding by Designed Bisbenzamidine-Homeodomain Chimeras
(WILEY-VCH Verlag GmbH, 2014-04-24)
We report the construction of conjugates between three variants of the helix 3 region of a Q50K engrailed homeodomain and bisbenzamidine minor-groove DNA binders. The hybrid featuring the sequence of the native protein ...
Rhodium-Catalyzed Intramolecular [3+2+2] Cycloadditions between Alkylidenecyclopropanes, Alkynes, and Alkenes
(WILEY-VCH Verlag GmbH, 2014-07-17)
A Rh-catalyzed intramolecular [3+2+2] cycloaddition is reported. The cycloaddition affords synthetically relevant 5,7,5-fused tricyclic systems of type 2 from readily available dienyne precursors. The transformation takes ...
Reversible supramolecular assembly at specific DNA sites: Ni-promoted, bivalent DNA binding with designed peptide and bipyridylbisbenzamidine components
(WILEY-VCH Verlag GmbH, 2014-07-15)
At specific DNA sites, nickel(II) salts promote the assembly of designed components, namely a bis(histidine)-modified peptide that is derived from a bZIP transcription factor and a bis(benzamidine) unit that is equipped ...
