A pro-drug is a substance administered in a pharmacologically inactive structure that, once administered, is metabolised in vivo into the corresponding active principle. The rationale for the design of prodrugs is the optimisation of absorption, distribution, metabolism, and excretion (ADME). Moreover these compounds are frequently synthesized to improve(More)
Simvastatin (SV), an analogue of lovastatin, is the lactone form of 1',2',6',7',8',8a'-hexahydro-3,5-dihydroxy-2',6'-dimethyl-8'(2'',2''-di met hyl-1''-oxobutoxy)-1'-naphthalene-heptanoic acid (SVA) which lowers plasma cholesterol by inhibiting 3-hydroxy-3-methylglutaryl-CoA reductase. A fast, simple and accurate method for determining SV and SVA(More)
Prostatic infections are difficult both to diagnose and to treat and have negative influences on the fertility of the patient. Norfloxacin, a new quinolone antibacterial agent particularly active in urinary tract infections, gave excellent results (400 mg every 12 h for 10 days) in the treatment of chronic-relapsing prostatitis in a group of 20 patients. An(More)
The anthraquinone profile, antioxidant and antimicrobial activities as well as the total phenol and total flavonoid contents were determined in methanol extracts of the barks of Rhamnus catharticus L. and R. orbiculatus Bornm. The most abundant anthraquinone derivatives in R. catharticus were physcion (67.8%) and emodin (26.2%), while R. orbiculatus(More)
INTRODUCTION Rhamnus alpinus L. (Rhamnaceae), a traditional plants in the flora of the Abruzzo region, is known to contain active anthraquinone secondary metabolites. However, the content of anthraquinones varies among R. alpinus samples depending on collection season and site. Thus, using simple, reliable and accurate analytical methods for the(More)
UNLABELLED Recently developed proteomic technologies allow to profile thousands of proteins within a high-throughput approach towards biomarker discovery, although results are not as satisfactory as expected. In the present study we demonstrate that serum proteome denaturation is a key underestimated feature; in fact, a new differential denaturation(More)
A method for the simultaneous determination of losartan potassium and hydrochlorothiazide in tablets is described. The procedure, based on the use of reversed-phase high-performance liquid chromatography, is linear in the concentration range 3.0-7.0 microg ml(-1) for losartan and 0.5-2.0 microg ml(-1) for hydrochlorothiazide, is simple and rapid and allows(More)
Prostate cancer is a critical public health problem in USA and Europe. New non-invasive imaging methods are urgently needed, due to the low accuracy and specificity of current screen methods and the desire of localizing primary prostate cancer and bone metastasis. Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT) are(More)
A simple and reliable HPLC method is described for the new beta-lactam antibiotic imipenem; suitable extraction procedures for the drug in human plasma, urine and prostatic tissue are described. The figures of merit for the assays are reported and examples given of their application.
The medicinal uses of saffron (Crocus sativus Linnaeus) have a long history beginning in Asian countries since the Late Bronze Age. Recent studies have validated its potential to lower the risk of several diseases. Some metabolites derived from saffron stigmas exert numerous therapeutic effects due to hypolipidemic, antitussive, antioxidant, antidiabetic(More)
