Aurora B is a serine-threonine kinase belonging to the highly conserved Aurora family of mitotic kinases. Aurora B is a chromosomal passenger protein involved in chromosome segregation, spindle-checkpoint, and cytokinesis. Alteration of each of these steps could induce aneuploidy, one of main features, and driving force of cancer progression. The overexpression of Aurora B has been observed in several tumor types, and Read More

The seven-spanning transmembrane G-protein coupled receptor CXCR4, which specifically binds to the chemokine CXCL12, is expressed on many cell types, including various types of tumour cells. CXCR4 plays a crucial role in organ-specific metastasis, directing migration of malignant cells expressing this receptor toward microenvironments where the cognate ligand is secreted. CXCL12 has a direct growth and survival-pro Read More

Breast cancer remains one of the first leading causes of death in women, and currently endocrine treatment is of major therapeutic value in patients with estrogen-receptor positive tumors. Selective estrogen-receptor modulators (SERMs), such as tamoxifen and raloxifene, aromatase inhibitors, and GnRH agonists are the drugs of choice. Tamoxifen, a partial nonsteroidal estrogen agonist, is a type II competitive inhibito Read More

Tubulin protein is one of several members of a small family of globular proteins. It offers a potential target for anticancer drug design and development. Combretastatin A-4 (CA-4) is a potent anticancer and antiangiogenesis natural substance isolated from Combretum caffrum. Modifications on the CA-4 structure have led to a great number of novel CA-4 derivatives as potent tubulin inhibitors and high cytotoxic Read More

Macrophages play an important role in the immune system. They also participate in multiple processes including angiogenesis and triggering of inflammation. The present study summarizes pieces of knowledge on the importance of macrophages in disease, especially the inflammation. Special attention is paid to the cholinergic anti-inflammatory pathway (CAP) associated with the nicotinic acetylcholine receptor (nAChR) Read More

Alzheimer's disease (AD) is the most common neurodegenerative disease, affecting mainly elderly people. The reasons why AD occurs are complex and multifactorial and several biochemical targets are thought to play a key role in its progress and development. This fact has led to the development of a multitarget-directed ligand strategy as a logical approach for designing a suitable therapy. Currently, most prescribed Read More

Insulin dependent diabetes mellitus (Type 1 diabetes, T1D) is a chronic autoimmune disorder characterized by the destruction of insulin-producing pancreatic beta cells by proinflammatory autoreactive T cells. In the past, several therapeutic approaches have been exploited by immunologists aiming to regulate the autoimmune response; this can occur by deleting lymphocyte subsets and/or re-establishing immune tolerance vi Read More

Epoxyeicosanoids, including the epoxyeicosatrienoic acids, are signaling molecules which appear to help ameliorate the effects of a wide variety of pathological conditions. The enzyme soluble epoxide hydrolase (sEH) metabolizes these molecules by converting them to their corresponding vicinal diols. Inhibition of sEH either by knockout or chemical inhibitors increases epoxyeicosanoid levels in vivo and provides significant Read More

Flaviviral infections have a re-emerging impact on the health situation in developing countries with several billion of people living at risk. In the present review, we focus on three members of the genus Flavivirus belonging to the Flaviviridae family. They are transmitted to humans by mosquito bites, namely those viruses leading to Dengue Fever, Yellow Fever and mosquito-borne Japanese encephalitis. All three virus gr Read More

Indoles represent an important structural class in medicinal chemistry with broad spectrum of biological activities. The synthesis of indoles, therefore, has attracted enormous attention from synthetic chemists. Microwave methods for the preparation of indole analogs have been developed to speed up the synthesis, therefore, microwave assisted organic synthesis (MAOS) in controlled conditions is an invaluable te Read More
