Reverse transcription of the viral single-stranded (+) RNA genome into double-stranded DNA is an essential step in the human immunodeficiency virus' (HIV) life-cycle. Although several viral proteins are involved in the regulation and/or efficiency of reverse transcription, the process of retroviral DNA synthesis is entirely dependent on the enzymatic activities of the retroviral reverse transcriptase enzyme (RT). Due to its Read More

The biological activity of peroxisome proliferators (PPs) is mediated by a class of receptors, known as PPARs (PP-Activated Receptor), belonging to the nuclear receptor superfamily. Upon ligand binding, PPARs dimerize with retinoid receptors, translocate to the nucleus, recognize specific PP-responsive elements on DNA and transactivate a number of genes. Several processes are regulated by PPARs, such as mitochondrial an Read More

Compound lipophilicity connected to ADME(T)a has great importance in drug development and it has to be evaluated by the generally used drug developmental process. In addition to the importance of lipophilicity in ADMET, recently it has been reported that lipophilicity of small molecules correlates with their antiproliferative activity because of certain specific hydrophobic and lipophilic interactions. Due to the complexity of Read More

The biogenic amine serotonin (5-hydroxytryptamine, 5-HT) is one of the most studied neurotransmitters in the central nervous system. It acts through the activation of at least fourteen 5-HT receptor subtypes. Over the last two decades, high attention was devoted to the 5-HT3 and 5-HT4 receptors due to their colocalization in the gastrointestinal tract and because their ligands are useful in the treatment of intestinal serot Read More

Acute heart failure syndromes (AHFS) enclose a broad spectrum of conditions with different clinical presentations, heart failure history, pathophysiology, prognosis and treatment. AHFS represent a major public health problem because of their high prevalence, high rates of mortality and readmissions and significant healthcare costs, and a therapeutic challenge for the clinicians because management strategies vary Read More
