Platinum drugs are widely used in antitumour therapy and are a cornerstone of the treatment of different solid tumours. The pharmacological interest of cisplatin has led to the design of many analogues to broaden the spectrum of activity, reduce side effects, and overcome resistance. Although the cis configuration was initially identified as the only active one, trans-platinum complexes have shown significant antitumour Read More

Shock waves (SW), defined as a sequence of single sonic pulses characterised by high peak pressure (100 MPa), a fast rise in pressure (< 10 ns) and a short lifecycle (10 μs), are conveyed by an appropriate generator to a specific target area at an energy density ranging from 0.03 to 0.11 mJ/mm2. Extracorporeal SW (ESW) therapy was first used on patients in 1980 to break up kidney stones. During the last ten years, this t Read More

Nitric oxide (NO) is a short-life molecule produced by the enzyme known as the nitric oxide synthase (NOS), in a reaction that converts arginine and oxygen into citrulline and NO. There are three isoforms of the enzyme: neuronal NOS (nNOS, also called NOS1), inducible NOS (iNOS or NOS2), and endothelial NOS (eNOS or NOS3). It is now known that each of these isoforms may be expressed in a variety of tissues and cell types. Th Read More

Degenerative diseases are still a challenging issue in clinical therapy; even though in several cases it is possible to treat symptoms, drugs able to block disease progression are lacking at present. Osteoarthritis (OA) and Rheumatoid Arthritis (RA) are degenerative diseases leading to serious cartilage destruction, affecting joint functions and giving rise to restricted movement, pain and chronic disability. Current clinical treatme Read More

Iron chelators are being examined as a potential class of pharmaceutical agents to battle different types of cancer as well as iron overload diseases. In recent studies, iron binding species such as desferrioxamine, triapine, tachpyridine, Dp44Mt, and PIH have been tested in cell line tests and clinical trials. Using published chemical equilibrium values (stability constants, equilibrium constants), it is argued that an iron chelat Read More

Substituted 2-arylbenzothiazoles have emerged in recent years as an important pharmacophore in a number of diagnostic and therapeutic settings. Attractive features of drug candidates based on this benzothiazole scaffold include their synthetic accessibility, and synthetic approaches to 2-arylbenzothiazole-based compounds will be reviewed here. Examples of 2-arylbenzothiazoles endowed with diagnostic/therapeutic Read More

Dopamine and serotonin are important neurotransmitters in the mammalian central nervous system (CNS) involved in numerous physiological and behavioural disorders such as schizophrenia, major depression, anxiety, Parkinson's and Huntington's diseases, and attention deficit hyperactivity disorder. Several natural and synthetic benzylisoquinoline derivatives have displayed affinity for dopamine and serotonin receptors in na Read More

Fentanyl is the prototype of the 4-anilidopiperidine class of synthetic opioid analgesics. This study was aimed to review the structure-activity-relationship (SAR) of fentanyl analogs substituted in the position 3, or 4 of the piperidine ring. Pharmacological results show that the groups in position 3 of the piperidine ring, which are larger than methyl, severely reduce the analgesic potency compared to fentanyl. It is likely th Read More

The dawning of this millennium broke new ground in life science and technology, presented us genomic and proteomic revolution, nanotechnology innovation, and high performance liquid chromatography coupled with tandem mass spectrometry (LC/MS/MS) used for separating and identifying new chemical entities at pico-, or even femtoconcentrations. Applications of these high technologies to the traditional Chinese medicine Read More
