The intramolecular hydrogen bonding in the ?-azido secondary acetamides (?-AzSAs) enabled site-selective integration onto diazide modular hubs even without steric hindrance.

Histone deacetylase inhibitors have gained a great deal of attention recently for the treatment of cancers and inflammatory diseases. So design of new inhibitors is of great importance in pharmaceutical industries and labs. Creating pharmacophor models in order to design new molecules or search a library for finding lead compounds is of great interest. This approach reduces the overall cost ass...

Foreword The Slovak National Committee for IUGG is pleased to present the second Slovak National Report to IUGG which should provide a concise summary of the geophysical and geodaetic research, and results accomplished in the period of 1999 – 2002 in the Slovak Republic. The Report consists of partial reports to five associations – IAG, IAGA, IAHS, IAMAS and IASPEI. The reports to associations ...

6-Azafulleroid-6-deoxy-2,3-di-O-myristoylcellulose (3) was synthesized from 6-azido-6-deoxycellulose (1) by two reaction steps. The myristoylation of compound 1 with myristoyl chloride/pyridine proceeded smoothly to give 6-azido-6-deoxy-2,3-di-O-myristoylcellulose (2) in 97.0% yield. The reaction of compound 2 with fullerene (C(60)) was carried out by microwave heating to afford compound 3 in h...

For many years the urban renewal approach of Rotterdam, executed during the period 19751993, served as an example on the national and international level. With this approach a process of revitalization was initiated, which meant that the urban fabric and building supply had to adapt to changing conditions and accommodate new demands. Due to large financial and social investments in Rotterdam, a...

Three dimensional pharmacophores and pharmacophore searches are well established in virtual screening and have been applied successfully in many prospective and retrospective drug discovery campaigns [1]. While the pharmacophore concept offers an easy and abstract understanding of molecular properties, plenty of user intervention is required to define feasible models. Recently, Silicos NV provi...

The metal cations-polysaccharides complexes play crucial roles in the process of immune cell recognitions. Here, we create simpler biomimetic ligands, which emulate binding carbohydrates living organisms. We present a detailed study on interactions Cu2+, Ni2+ and VO2+ ions with t-butyl 3-azido- 3-amino-2,3-dideoxy-α-d-arabino-hexopyranosides. NMR, IR UV–Vis spectroscopies as well single crystal...

A combined ligand and structure-based drug design approach provides a synergistic advantage over either methods performed individually. Present work bestows a good assembly of ligand and structure-based pharmacophore generation concept. Ligand-oriented study was accomplished by employing the HypoGen module of Catalyst in which we have translated the experimental findings into 3-D pharmacophore ...

We have recently presented a new pharmacophore design method that allows for the incorporation of the inherent flexibility of a target active site. The flexibility of the enzymatic system is described by collecting many conformations of the uncomplexed protein; this ensemble of conformational states can come from a molecular dynamics (MD) simulation, multiple crystal structures, or many NMR str...
