2015

Objective: To explore the effects of the glucagon-like peptide-1 receptor analogue liraglutide on subclinical atherosclerosis in diabetic subjects with non-alcoholic fatty liver disease (NAFLD).Research design and methods: In this 8-month prospective study, 29 subjects with type 2 diabetes (T2DM) and NAFLD (16 men and 13 women, mean age: 61 ± 10 years) were matched for age and gender with 29 subjects with T2DM without NAFLD (16 men and 13 women, mean age: 61 ± 8 years). Liraglutide 0.6 mg/day for 2 weeks, followed by 1.2 mg/day, was given in addition to metformin.Main outcome measures: Anthropometric variables, glucometabolic parameters and carotid intima-media thickness (IMT) using B-mode …

Ethnobotanical investigation on wild medicinal plants in the Monti Sicani Regional Park (Sicily, Italy)

2014

Ethnopharmacological relevance The area of the "Monte Sicani Regional Park" (Central Western Sicily, southern Italy) has been quantitatively and extensively investigated in an ethnobotanical study for the first time. A total of 108 wild species are used for medicinal purposes, while, according to our study, the uses of 9 species have not previously been reported in ethnobotanical studies in Italy (e.g.; the use of Kickxia elatine (L.) Dumort. for the treatment of hyperhydrosis of the feet, the use of Lavatera agrigentina Tineo for cough and bronchitis). Aim of the study: The aim of this paper is to analyze, through quantitative indicators, the extent of the current knowledge on medicinal us…

Δ5-Cholenoyl-amino acids as selective and orally available antagonists of the Epheephrin system

2015

The Eph receptor-ephrin system is an emerging target for the development of novel anti-angiogenic therapies. Research programs aimed at developing small-molecule antagonists of the Eph receptors are still in their initial stage as available compounds suffer from pharmacological drawbacks, limiting their application in vitro and in vivo. In the present work, we report the design, synthesis and evaluation of structure-activity relationships of a class of Δ(5)-cholenoyl-amino acid conjugates as Eph-ephrin antagonists. As a major achievement of our exploration, we identified N-(3β-hydroxy-Δ(5)-cholen-24-oyl)-L-tryptophan (UniPR1331) as the first small molecule antagonist of the Eph-ephrin syste…

Preclinical Activity of New [1,2]Oxazolo[5,4-e]isoindole Derivatives in Diffuse Malignant Peritoneal Mesothelioma

2016

A series of 22 derivatives of the [1,2]oxazolo[5,4-e]isoindole system were synthesized through an efficient and versatile procedure that involves the annelation of the [1,2]oxazole moiety to the isoindole ring, producing derivatives with a wide substitution pattern. The structure-activity relationship indicates that the N-4-methoxybenzyl group appears crucial for potent activity. In addition, the presence of a 6-phenyl moiety is important and the best activity is reached with a 3,4,5-trimethoxy substituent. The most active compound, bearing both the structural features, was able to inhibit tumor cell proliferation at nanomolar concentrations when tested against the full NCI human tumor cell…

The Repurposing of Old Drugs or Unsuccessful Lead Compounds by in Silico Approaches: New Advances and Perspectives

2015

Have you a compound in your lab, which was not successful against the designed target, or a drug that is no more attractive? The drug repurposing represents the right way to reconsider them. It can be defined as the modern and rationale approach of the traditional methods adopted in drug discovery, based on the knowledge, insight and luck, alias known as serendipity. This repurposing approach can be applied both in silico and in wet. In this review we report the molecular modeling facilities that can be of huge support in the repurposing of drugs and/or unsuccessful lead compounds. In the last decades, different methods were proposed to help the scientists in drug design and in drug repurpo…

Essential Oils and Pure Volatile Compounds as Potential Drugs in Alzheimer's Disease Therapy: An Updated Review of the Literature

2016

Background: The use of aromatic plants to relief different illness is not a new therapy. Actually aromatic plants have been used for many centuries by different cultures around the world. Pharmacological studies provide scientific support to the traditional use of aromatic medicinal plants and aromatherapy; nevertheless, more clinical trials are required regarding to their effectiveness in order to establish a guidance for their use in routine healthcare. Moreover, modern medicine in studies about olfactory function has attained great achievements and got Nobel Prize in 2004. These new searches have obviously fueled interest in the essential oils and volatile compounds of natural origin. Se…

Monoclonal antibodies in gastrointestinal cancers

2013

Introduction: Among gastrointestinal cancers, colorectal and gastric neoplasms are the most frequent. The development of new targeted drugs improved the efficacy of systemic therapy in advanced stages of those malignancies. Areas covered: This review highlights the main biological processes implicated in gastrointestinal cancer development and progression, such as angiogenesis and epidermal growth factor receptor (EGFR) signaling pathway. On these bases, anti-EGFR and anti-vascular endothelial growth factor (VEGF) monoclonal antibodies in colorectal and gastric cancer are discussed. Data about further monoclonal antibodies in development are also reported. Expert opinion: The use of monoclo…

Human equilibrative nucleoside transporter 1 (hENT1) levels predict response to gemcitabine in patients with biliary tract cancer (BTC)

2009

Background and aim: Translational data suggest that nucleoside transporters, in particular human equilibrative nucleoside transporter 1 (hENT1), play an important role in predicting clinical outcome after gemcitabine chemotherapy for several types of cancer. The aim of this study was to retrospectively determine patients' outcome according to the expression of hENT1 in tumoral cells of patients receiving gemcitabine-based therapy. Materials and Methods: The immunohistochemistry analysis was performed on samples from thirty-one patients with unresectable biliary tract cancer (BTC) consecutively treated with first line gemcitabine-based regimens. Results: Positive hENT1 staining patients were…
