Coumarins, also known as benzopyrones, are present in remarkable amounts in plants, although their presence has also been detected in microorganisms and animal sources. The structural diversity found in this family of compounds led to the division into different categories, from simple coumarins to many other kinds of policyclic coumarins, such as furocoumarins and pyranocoumarins. Simple coumarins and anal Read More

Matrix metalloproteinases (MMP) and their inhibitors (TIMP) are central factors in the control of extracellular matrix turnover. They are important in normal physiology and also during a range of pathological states. Only recently has their role in cardiovascular disease been explored and their analysis through measurements in blood been studied. We have systematically identified clinical articles relevant to coronary artery dise Read More

The object of this paper is to summarize for the past two years the most recent development in the field of prostate cancer and 5α-reductase inhibitors. In addition we are also including some results on the synthesis and pharmacological evaluation of new steroidal compounds developed in our laboratory. Most of the new steroidal derivatives are based on the progesterone skeleton and showed a high inhibitory activity for th Read More

Chagas Disease, caused by the T. cruzi parasite, is one of the largest public health problems in the Western hemisphere. Although its spread has diminished due to vector eradication programs, effective chemotherapeutics for the disease itself remain elusive. Many efforts towards the development of antiparasitic agents active against a number of targets have been described recently in the literature. This review sum Read More

G-protein-coupled receptors (GPCRs) constitute the largest but the most divergent class of cell surface proteins. Although they are thought to share a common 3D-structure composed of seven transmembrane helical domains, they can be activated by extracellular signals as diverse as light, peptides, proteins, lipids, organic odorants, taste molecules, nucleotides or nucleosides. They are involved in an extraordinarily large nu Read More

In this review the structural and functional aspects of dipeptidyl peptidase IV (DPP IV) will be described, and the therapeutic potential of DPP IV inhibitors will be highlighted. DPP IV will be situated in clan SC, a group of serine proteases that contains several proline specific peptidases. Structural aspects of DPP IV and its interaction with different types of inhibitors are recently revealed by the publication of several crysta Read More
