Human neutrophil elastase (HNE), a main actor in the development of chronic obstructive pulmonary diseases, has been recently involved in non-small cell lung cancer progression. It can act at several levels (i) intracellularly, cleaving for instance the adaptor molecule insulin receptor substrate-1 (IRS-1) (ii) at the cell surface, hydrolyzing receptors as CD40 (iii) in the extracellular space, generating elastin fragments i.e. Read More

The effect of anticoagulant adjuvant anti-tumor therapy depends on the cancer type and stage and on the type of the used anticoagulant drug. A striking response rate was described in experiments involving human patients with lung cancer. The aim of this study is to review anticoagulant and fibrinolytic drugs as antitumor agents with focus on their clinical use. The first part of the review evaluates the results of clinical studies.

Urothelial cell carcinoma is one of the most common malignancies of the urinary tract. The standard of care, intravesical chemo- and immunotherapy, while effective, is associated with a considerable side-effect profile and approximately 30% of patients either fail to respond to treatment or suffer recurrent disease within 5 years. In the setting of muscle-invasive urothelial carcinoma, use of neoadjuvant chemoth Read More

The octacarboxyl gallium (GaPcC) and metal-free (H2PcC) phthalocyanines were prepared using the carboxyl as the peripheral substituent. The carboxylation improves the intracellular delivery of these two PcCs into KB and QGY cancer cells as compared to that of sulfonated aluminum phthalocyanines (AlPcS), a popularly used photosensitizer (PS). Moreover, GaPcC maintains high photoproduction of singlet oxygen. With Read More

A series of 5-aryl-1,4-benzodiazepines with chloro- or fluoro-substituents in the second ring have been synthesized and their anti-inflammatory, myeloperoxidase and anticancer properties studied. The synthesized compounds showed potential anti-inflammatory and anticancer activities, which were enhanced in the presence of a chloro-substituent in the second ring of the 5-aryl-1,4- benzodiazepine.

Background: Accumulating evidence suggest that dietary modification can lower the risk for several cancer types’ development. Cranberry in particular, has been shown to have anti-oxidative, -inflammatory and -proliferative properties in vitro. Objective: To present the latest knowledge regarding the role of cranberry extracts against human cancer several types. Methods: A review of the literature documenting both in vi Read More

Cell division cycle 25 A (Cdc25A), a dual-specificity protein phosphatase, is one of the most crucial cell cycle regulators, which removes the inhibitory phosphorylation in cyclin-dependent kinases (CDKs), such as CDK2, CDK4, and CDK6, and positively regulates the activities of CDKs that lead to cell cycle progression. In addition, Cdc25A also acts as a regulator of apoptosis. Overexpression of Cdc25A promotes tumorigene Read More

New therapies for leukaemia are urgently needed. Carrots have been suggested as a potential treatment for leukaemia in traditional medicine and have previously been studied in other contexts as potential sources of anticancer agents. Indicating that carrots may contain bioactive compounds, which may show potential in leukaemia therapies. This study investigated the effects of five fractions from carrot juice extract (CJE) on h Read More

In targeted cancer therapy the search for novel molecules led to the discovery of a plethora of small organic molecules inhibiting cancer cell proliferation. Among these, quinazoline and derivatives, such as quinolines and naphthyridines, have been considered as of particular interest. One of these, the naphthyridine derivative 4-phenyl-2,7-di(piperazin-1-yl)-1,8-naphthyridine, has been analyzed in detail in the present work. Read More

1,3-dimethyl-1,3-bis(4-fluorophenyl)-1,3-bis{3-[1(4-butylpiperazinyl)]-propyl}-disiloxan-tetrahydrochlorid (SILA 421) is a compound that was developed as modulator of the ABC cassette transporter P-glycoprotein. Furthermore, it exerted antimicrobial toxicity, vascular effects, downregulation of chaperone induction and plasmid curing in bacterial cells. Here, this drug was found to possess cytotoxic activity agai Read More

Recent gene profiling studies have identified at least 5 major subtypes of breast cancer, including normal type, luminal A type, luminal B type, human epidermal growth factor receptor (HER)-2 positive type, and basal-like type. Triple-negative breast cancer (TNBC), showing no or low expressions of estrogen receptor (ER), progesterone receptor (PgR), and HER2, considered important clinical biomarkers, accounts for 1 Read More

A brain tumor (BT) constitutes a neoplasm located in the brain or the central spinal canal. The number of new diagnosed cases with BT increases with the pass of the time. Understanding the biology of BT is essential for the development of novel therapeutic strategies, in order to prevent or deal with this disease. An active area for the search of new anti-BT therapies is the use of Chemoinformatics and/or Bioinformatics towa Read More
