DNA damaging agents including anthracyclines, camptothecins and platinum drugs are among most frequently used drugs in the chemotherapeutic routine. Due to their relatively low selectivity for cancer cells, administration of these drugs is associated with adverse side effects, inherent genotoxicity with risk of developing secondary cancers. Development of new drugs, which could be spared of these drawbacks and char Read More

DNA has represented the most exploited target for the development of anticancer agents. It is now established that DNA may assume a variety of non-B conformations. This evidence has generated a total novel wave of interest in DNA as a cancer-associated target, since its distinct non-B structures may be regarded as sites for selective therapeutic intervention. G-quadruplexes are peculiar non-B DNA conformations that Read More

Despite the efficacy of most cancer therapies, drug resistance remains a major problem in the clinic. The eradication of the entire tumor and the cure of the patient by chemotherapy alone are rare, in particular for advanced disease. From an evolutionary perspective, the selective pressure exerted by chemotherapy leads to the emergence of resistant clones where resistance can be associated with many different functional Read More

Cisplatin is widely used as a cancer chemotherapeutic agent and this review covers the mechanism of action of cisplatin, cellular resistance to cisplatin, the genomic location of cisplatin adducts and the properties of DNA-targeted Pt complexes. A particular focus of this review is the interaction of Pt compounds with DNA. The technology involved in determining Pt-drug/DNA interactions has advanced and permits clea Read More

Medicinal inorganic chemistry plays an important role in exploring the properties of metal ions for the designing of new drugs. The field has been stimulated by the success of cis-platin, the world best selling anticancer drug and platinum complexes with reduced toxicity, oral activity and activity against resistant tumors are currently on clinical trial. The use of cis-platin is, however, severely limited by its toxic side-effects. Read More

The hyaline cartilage is an avascular, aneural and alymphatic tissue with a limited ability to repair itself. When the cartilage is exposed to some kind of injury, it usually triggers osteoarthritis (OA), a prevalent and degenerative joint disease closely related to aging. OA is both complex and multifactorial, and is the most common form of arthritis, being positioned as a major cause of pain and dysfunction in the world. In addit Read More

The Hand, Foot and Mouth Disease (HFMD) is caused by Enterovirus 71 (EV-A71) and Coxsackieviruses. Common HFMD symptoms are high fever (≥ 39°C), rashes, and ulcers but complications due to virulent EV-A71 may arise leading to cardiopulmonary failure and death. The lack of vaccines and antiviral drugs against EV-A71 highlights the urgency of developing preventive and treatment agents. Recent studies have reported Read More

The health benefits of plant food-based diets could be related to both integrated antioxidant and antiinflammatory mechanisms exerted by a wide array of phytochemicals present in fruit, vegetables, herbs and spices. Therefore, there is mounting interest in identifying foods, food extracts and phytochemical formulations from plant sources which are able to efficiently modulate oxidative and inflammatory stress to prevent diet- Read More

Background: We conducted a comparison between the dipeptidyl-peptidase-4(DPP-4) inhibitor sitagliptin versus NPH insulin as an add-on therapies in patients with type 2 diabetes mellitus (T2D) failing oral medications. The objective was to ascertain the better indication in long-duration diabetes. Methods: thirty-five T2D patients inadequately controlled with metformin plus glyburide were randomized to receive sitagliptin Read More
