A new class of compounds that exhibit anti-norovirus activity in a cell-based system and embody in their structure a cyclosulfamide scaffold has been identified. The structure of the initial hit (compound 2a, ED50 4 μM, TD50 50 μM) has been prospected by exploiting multiple points of diversity and generating appropriate structure–activity relationships.
and to inhibit ERKs phosphorylation, without acting directly on microtubules and tubuline. Its theoretical recognition against duplex and quadruplexDNA structures have been compared to experimental thermodynamic measurements and by molecular modeling investigation leading to putative binding modes. Taken together these findings contribute to define this compound as potential Multitarget-Directed Ligands
general formula [Mn(CO) 3 (bpy)L]PF 6 (bpy = 2,2-bipyridyl, L = N-(2-chlorobenzyl)benzimidazole, N-(2-methoxybenzyl)benzimidazole, N-(2-methylbenzyl)benzimidazole). The complex molecules were characterized by LC-MS, 1 H-NMR, 13 C-NMR, IR spectroscopy methods and elemental analysis. The CO-releasing properties, antioxidant activities and redox properties of these complexes were investigated. The DFT/TDDFT

A composition for making a polyurethane foam includes a non-fugitive tertiary amine urethane catalyst and an alkylated polyamine crosslinking additives. Foams prepared from the reaction of a polyol and an organic isocyanate in the presence of these ingredients show improved resistance to deterioration of physical properties upon humid aging.
The invention provides novel substituted azaheterocyclic compounds according to Formula (I), their manufacture and use for the treatment of hyperproliferative diseases, such as cancer.
