Article
Anti-inflammatory drugs represent a potential new strategy for the treatment of Alzheimer's disease (AD). The ability to cross the blood-brain barrier and to reach brain tissues is a critical point for these drugs and is strictly related to their lipophilicity. Naproxen (NAP) is a non-steroidal anti-inflammatory drug (NSAIDs) under active investiga...
Article
Nanoparticles (NPs) formed from polymers conjugated with bisphosphonates (BPs) allow the bone targeting of loaded drugs, such as doxorubicin, for the treatment of skeletal tumours. The additional antiosteoclastic effect of the conjugated BP could contribute to the inhibition of tumour-associated bone degradation. With this aim, we have produced NPs...
Article
Bone metastases contribute to morbidity in patients with common cancers, and conventional therapy provides only palliation and can induce systemic side effects. The development of nanostructured delivery systems that combine carriers with bone-targeting molecules can potentially overcome the drawbacks presented by conventional approaches. We have r...
Article
Acyclovir has been conjugated to the acyclic isoprenoid chain of squalene to form the squalenoyl-acyclovir prodrug. Its interaction with biomembrane models constituted by dimyristoylphosphatidylcholine (DMPC) monolayers has been studied by employing the Langmuir-Blodgett technique. The aim of the work was to gain information on the interaction of t...
Article
Omega-3 fatty acids, contained in vegetables and fish, exert several beneficial effects on the human health. The interaction of three omega-3 fatty acids (linolenic acid, docosapentaenoic acid and docosahexaenoic acid) with and their absorption by biomembrane models (represented by dimyristoylphosphatidylcholine multilamellar and unilamellar vesicl...
Article
The interaction of eicosapentaenoic acid, a polyunsaturated fatty acid belonging to the omega-3 class, with biomembrane models represented by multilamellar or unilamellar vesicles made of dimyristoylphosphatidylcholine was monitored by means of differential scanning calorimetry technique. The calorimetric analysis of vesicle prepared in the presenc...
Article
Differential scanning calorimetry was used to study the interaction of acyclovir and its prodrug squalenoyl-acyclovir (obtained by conjugation of 1,1',2-tris-nor-squalene acid (squaleneCOOH) with acyclovir) with biomembrane models made of DMPC multilamellar vesicles with the aim to verify whether a stronger interaction of the prodrug with respect t...
Article
Diethyltoluamide and ethylhexyl p-methoxycinnamate (OMC) are two active ingredients in insect repellent and sunscreen products, respectively. The concurrent application of these two substances often increases their systemic absorption, compromising the safety and efficiency of the cosmetic product. In this study, diethyltoluamide and OMC were incor...

Osteotropic drug-delivery systems have been proposed as a means to provide drugs with affinity to bone tissues. Drugs or proteins have been linked chemically to bone-seeking agents, such as bisphosphonates (BPs); alternatively, drug-loaded nanoparticles have been used to target specific tissues, such as tumor areas. In our current research, these a...
Article
Inulin has been derivatized with methacrylic anhydride (MA) and succinic anhydride (SA) to obtain a methacrylated/succinilated derivative (INU-MA-SA) able to produce a pH sensitive hydrogel after UV irradiation. The hydrogel was characterized and loaded with diflunisal (10.4, 17 and 24%, w/w) chosen as a model drug. The drug release from INU-MA-SA-...
Article
A differential scanning calorimetry study was carried out to investigate the effect exerted by immunogenic synthetic lipopeptides obtained by the conjugation of LCMV33–41 peptide with lipoamino acids (Laas) bearing different alkyl chain lengths (C12 and C16) and number of chains (2 × C12) on the thermotropic behaviour of dimyristoylphosphatidylchol...
Article
Nanoparticles made of a conjugate of poly(D,L-lactide-co-glycolide) with alendronate (PLGA-ALE NPs), were prepared by emulsion/solvent evaporation technique. The conjugation yield, determined by MALDI TOF analysis, was 30-35%. PLGA-ALE NPs size, evaluated by photon correlation spectroscopy, was 198.7+/-0.2 nm. Haemocompatibility studies using diffe...
Article
To demonstrate the relationship between the structure of nitro-polycyclic aromatic hydrocarbons and their effect on biomembranes, we have investigated the influence of three structurally different nitropolycyclic aromatic hydrocarbons, 2-nitrofluorene, 2,7-dinitrofluorene and 3-nitrofluoranthene, on the thermotropic behavior of dimyristoylphosphati...
Article
Molecular interactions between gemcitabine, alone or conjugated with squalene to form the gem-squalene prodrug, with dimyristoylphosphatidylcholine have been investigated by differential scanning calorimetry and Langmuir film balance techniques to gain information about the interaction of gemcitabine and its prodrug with mammalian cell membranes an...
Article
The present article reports the antimicrobial efficacy of four monoterpenes (thymol, carvacrol, p-cymene, and gamma-terpinene) against the Gram-positive bacterium Staphylococcus aureus and the Gram-negative bacterium Escherichia coli. For a better understanding of their mechanism of action, the damage caused by these four monoterpenes on biomembran...
Article
The interaction of resveratrol (trans-3,5,4'-trihydroxystilbene) and two of its derivatives (3,5,4'-tri-O-methylresveratrol and 3,5,4'-tri-O-triacetylresveratrol) with biomembrane models, represented by dimyristoylphosphatidylcholine (DMPC) multilamellar vesicles (MLV), has been studied by differential scanning calorimetry (DSC). The analysis of ML...
Article
beta-Sitosterol is a plant sterol that has received much attention because of its effectiveness in reducing the absorption of dietary cholesterol, as well as in offering protection from cardiovascular diseases and cancer development. Thus, the knowledge of the interaction of beta-sitosterol with biological membranes can help in understanding its me...
Article
The ability of herbicides to interact with cell membranes outer lipid layer and subsequently to penetrate inside cells can be a prerequisite for exhibiting a toxic activity for both the directly exposed workers and the end consumers as the herbicides are present in the soil and water. The effect exerted by fenuron, chlorotoluron, metobromuron, mono...
