West Nile Virus (WNV) has spread rapidly during the last decade across five continents causing disease and fatalities in humans and mammals. It highlights the serious threat to both our health and the economy posed by viruses crossing species, in this case from migratory birds via mosquitoes to mammals. There is no vaccine or antiviral drug for treating WNV infection. One attractive target for antiviral developmen Read More

Currently, breast cancer is considered as one of the leading causes for death in women in the United States. Consumption of natural products has received considerable attention in recent years as a possible approach for cancer prevention in general population. There are numerous cancer preventive agents present in the natural products, which may contribute to their chemopreventive properties. During the past two deca Read More

Polyethylenimine (PEI), an organic branched or linear polyamine polymer, has been successfully used in the past for DNA complexation and transfection in vitro and in vivo into several cell lines and tissues. PEI was also applied in different fields from gene therapy and several studies have emphasized the importance of this polymer in medicinal chemistry. In this brief critical review the uses and applications of this versatile Read More

Histone deacetylases (HDACs) and Histone acetyltransferases (HATs) are two kinds of enzymes, which can, by reversible deacetylation and acetylation, modify the structure and function of chromatin histones that are involved in the regulation of gene expression, as well as many non-histone proteins that regulate cell function in eukaryotes. Compared with HATs, HDACs have attracted more and more attentions for two Read More

APN is an important zinc dependent metallo-exopeptidase; it has been considered as a suitable target for anticancer drug design. In this review we focus on the most effective and the most promising inhibitors of aminopeptidase N. Their binding modes to the enzyme, the attempt to explain the origin of the inhibitory activity, as well as the structure - activity relationship for some of these compounds are discussed. Besides, the st Read More

Physical insults including but not limited to nerve damage, inflammation, visceral pathologies and cancer generate long lasting pain commonly referred as chronic pain. Recently, members of the chemokine family and their receptors emerged as key modulators in nociceptive influx transmission in neuropathic and inflammatory chronic pain models. To this day, rodents defective in specific chemokine receptors have Read More

Rho-kinase is an effector molecule of RhoA, a monomeric GTP-binding protein, and causes Ca2+ sensitization via inactivation of myosin phosphatase. The major physiological functions of Rho-kinase include contraction, migration, and proliferation in cells. These actions are thought to be related to the pathophysiological features of asthma, i.e., airflow limitation, airway hyperresponsiveness, β-adrenergic desensitizatio Read More

Artemisinin the sesquiterpene endoperoxide lactone extracted from the herb Artemisia annua, remains the basis for the current preferred treatment against the malaria parasite Plasmodium falciparum. In addition, artemisinin and its derivatives show additional anti-parasite, anti-cancer, and anti-viral properties. Widespread use of this valuable secondary metabolite has been hampered by low production in vivo a Read More
