The increasing emergence of multidrug resistant (MDR) pathogens, due to antibiotics misuse, leads to obstinate infections, with high morbidity and high-cost hospitalizations. To oppose these MDR superbugs, new antimicrobial options are necessary. Quaternary phosphonium salts (QPSs) have demonstrated appealing antibacterial properties, and a...

A series of poly(vinyl alcohol) amphiphilic derivatives have been prepared to obtain polymeric aggregates in aqueous phase holding thermodynamic instability. The aim was to evaluate their ability to interact with tumor cells eliciting selective cytotoxicity. The poly(vinyl alcohol) derivatives were prepared by partial substitution of poly(vinyl...

The progress in pharmaceutical technology at Genoa University has evolved in parallel with the advancement and consolidation of ADRITELF association, of which Prof. Gaetano Bignardi was one of the founding members and a staunch supporter. At the beginning, technological research took a slow start while remaining closely linked to the...

Background: Neuroblastoma (NB) is an extra-cranial solid tumour of childhood. In spite of the good clinical response to first-line therapy, complete eradication of NB cells is rarely achieved. Thus, new therapeutic strategies are needed to eradicate surviving NB cells and prevent relapse. Sodium ascorbate has been recently reported to induce...

Purpose: The major limitation to successful chemotherapy of neuroblastoma is the toxicity of traditional antitumor drugs. Hence, less toxic and more effective drugs are to be found, and novel formulations of conventional compounds allowing a more favorable biodistribution should be sought for. In an attempt to pursue this task, we recently...

The genus Acinetobacter consists of Gram‐negative obligate aerobic pathogens, including clinically relevant species, such as A. baumannii, which frequently cause hospital infections, affecting debilitated patients. The growing resistance to antimicrobial therapies shown by A. baumannii is reaching unacceptable levels in clinical practice, and...

All-trans-retinoic acid (ATRA) is now included in many antitumor therapeutic schemes for the treatment of acute promyelocytic leukemia, Kaposi's sarcoma, head and neck squamous cell carcinoma, ovarian carcinoma, bladder cancer, and neuroblastoma. Unfortunately, its poor aqueous solubility hampers its parenteral formulation, whereas oral...

Oleyl alcohol was complexed with new amphiphilic polyvinylalcohol derivatives with the aim of increasing its aqueous solubility, thus improving bioavailability and favoring its antitumor activity. Water-soluble amphiphilic polymers were prepared by polyvinyl alcohol (PVA) substitution with oleyl chains through a succinyl spacer at 2% and 3%...
