The development of modern technologies casts a new light on the natural products as an invaluable source of lead compounds that could guide drug discovery. Cancer stem cells are a subpopulation of cancer cells with a high clonogenic capacity and the ability to reform the parental tumours upon transplantation. They have been proposed to drive tumorigenesis(More)
Docetaxel has shown remarkable radiosensitizing in vitro properties. In a previous phase I/II dose escalation study in non-small-cell lung cancer (NSCLC) we observed a high response rate after concomitant boost radiotherapy and weekly docetaxel. The maximum tolerated dose was 30 mg m(-2) week(-1). In the present phase II study we evaluated whether weekly(More)
Cancer stem cells (CSCs) are a subpopulation of cancer cells with high clonogenic capacity and ability to reform parental tumors upon transplantation. Resistance to therapy has been shown for several types of CSC and, therefore, they have been proposed as the cause of tumor relapse. Consequently, much effort has been made to design molecules that can target(More)
A collection of compounds, structurally related to the anticancer drug tamoxifen, used in breast cancer therapy, were designed and synthesized as potential anticancer agents. McMurry coupling reaction was used as the key synthetic step in the preparation of these analogues and the structural assignment of E, Z isomers was determined on the basis of 2D-NOESY(More)
Previous epidemiological studies linking drinking water total trihalomethanes (THM) with pregnancy disorders or bladder cancer have not accounted for specific household cleaning activities that could enhance THM exposures. We examined the relation between household cleaning activities (washing dishes/clothes, mopping, toilet cleaning, and washing(More)
The synthesis of a series of novel trisubstituted pyrazole derivatives and their PIFA-mediated conversion to molecules bearing the fused pyrazolo[4,3-c]quinoline ring system is reported. The anti-angiogenic activity of these compounds was evaluated by using in vitro assays for endothelial cell proliferation and migration, and in the chicken chorioallantoic(More)
The present study reports the preparation of a novel class of squalene conjugates with paclitaxel, podophyllotoxin, camptothecin and epothilone A. The obtained compounds are characterized by a squalene tail that makes them able to self-assemble in water, and by a drug unit connected via a disulfide-containing linker to secure the release inside the cell.(More)
Self-assembly drug conjugate preparation is a promising approach to improve activity and penetration through physiological barriers of potent small molecules, as well as to reduce any side effects. Drug conjugates can self-assemble in water to form nanoparticles (NPs) that offer several advantages because: (i) they are easy to obtain; (ii) they can reach(More)
Developmental dysplasia of the hip (DDH) or congenital hip dysplasia (CDH) is the most prevalent developmental childhood hip disorder. It includes a wide spectrum of hip abnormalities ranging from dysplasia to subluxation and complete dislocation of the hip joint. The natural history of neglected DDH in adults is highly variable. The mean age of onset of(More)
