In their structural multiplicity and in the extent to which they occur in nature the derivatives of benzofuran are significantly lesser than the isoelectronic analogue indoles. However, these heterocyclic compounds show a variety of pharmacological properties, and change of their structure offers a high degree of diversity that has proven useful for the search of new therapeutic agents. The broad spectrum of phar Read More

Topological polar surface area (TPSA), which makes use of functional group contributions based on a large database of structures, is a convenient measure of the polar surface area that avoids the need to calculate ligand 3D structure or to decide which is the relevant biological conformation or conformations. We demonstrate the utility of TPSA in 2DQSAR for 14 sets of diverse pharmacological activity data. Even though a lar Read More

Novel therapeutic strategies are urgently needed for the treatment of serious diseases caused by viral, bacterial and parasitic infections, because currently used drugs are facing the problem of rapidly emerging resistance. There is also an urgent need for agents that act on novel pathogen-specific targets, in order to expand the repertoire of possible therapies. The high throughput screening of diverse small molecule compo Read More

Targeted therapy is considerably changing the treatment and prognosis of cancer. Progressive understanding of the molecular mechanisms that regulate the establishment and progression of different tumors is leading to ever more specific and efficacious pharmacological approaches. In this picture, ion channels represent an unexpected, but very promising, player. The expression and activity of different channel types mark a Read More

Micro- and macrovascular complications are major causes of disability and death in patients with diabetes mellitus. Functional impairment of endothelial activity precedes the development of morphological alterations during the progression of diabetes. This endothelial dysfunction results from reduced bioavailability of the vasodilator nitric oxide (NO), mainly due to accelerated NO degradation by reactive oxygen species ( Read More

Iron is one of the essential minerals that are required for a variety of molecules to maintain their normal structures and functions and for cells to live, grow, and proliferate. The homeostasis of iron results from a tightly coordinated regulation by different proteins involved in uptake, excretion and intracellular storage/trafficking. Although it is essential, iron can also be toxic once in excess amounts. Through Fenton reaction, iro Read More
