This study was designed to develop a drug-in-adhesive (DIA) type transdermal drug delivery system (TDDS) for D-threo-methylphenidate (D-threo-MP) that could be further developed for treating Attention-Deficit/Hyperactivity Disorder (ADHD) in children. During initial formulation optimization, thr...

ABSTRACTObjective:To evaluate clinical measures of the benefit/risk ratio in a post hoc analysis of a clinical trial of d-threo-methylphenidate hydrochloride (d-MPH) and d,l-threo-methylphenidate hydrochloride (d,l-MPH).

AA-BB and AB-type Non-Isocyanate Polyurethanes (NIPUs) were synthesized through a cross metathesis polymerization between methyl carbamate and methyl carbonate groups within AA-BB and AB monomers. These monomers were prepared by reaction of diamines, diols or amino-alcohols with an excess of dim...

Non-isocyanate thermoplastic polyureas (NIPUreas) were synthesized using an original approach. Dimethyl dicarbamates (DC) were prepared as monomers, by the reaction of a diamine with an excess of dimethylcarbonate (DMC), in presence of 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) as catalyst. Then,...

Mesoporous silica SBA-15 and ZrSBA-15 (Si/Zr = 10) were prepared and used as supports of platinum and molybdenum based catalysts to be tested in the hydrodeoxygenation (HDO) reaction of dibenzofuran (DBF) as a model compound present in biomass derived bio-oil, at 3 MPa and 275 °C. It is evaluat...

The infrared spectra of acetyl bromide and acetyl bromide-d3 and the Raman spectrum of the heavy compound have been measured. A vibrational assignment similar to that proposed for acetyl chloride has been made.

The molecular structures of acetyl fluoride and acetyl iodide have been determined by making use of the average distances obtained in the present study together with the moments of inertia reported in the literature. The large amplitude theory for a molecule with an internal top was used in the ...

This work focuses on the interaction of N′-acetyl-rifabutin (RFB2) and N′-butanoyl-rifabutin (RFB3) with human and bacterial cell membrane models under physiological conditions. The effect of RFB2 and RFB3 on human cell membrane models was assessed using multilamellar vesicles (MLVs) composed ...

S-Nitrosothiols from low-molecular-mass and high-molecular-mass thiols, including glutathione, albumin and hemoglobin, are endogenous potent vasodilators and inhibitors of platelet aggregation. By utilizing the S-transnitrosation reaction and by using the lipophilic (pKL 0.78) and strong nucleop...

Ultraviolet (UV) irradiation of amorphous and crystalline samples of solid acetyl chloride produces metastable HCl · ketene complexes in a 1:1 ratio following S1 photoexcitation. The HCl · ketene complex is the only product observed following UV irradiation of either amorphous or crystalline s...

The present study was aimed at investigation of thiolated derivative of chitosan for development of microspheres for ocular delivery of the antiviral agent, acyclovir. N-Acetyl cysteine was hereby covalently attached to chitosan via a carbodiimide mediated coupling reaction. The resulting chitos...

Streptococcus suis serotype 3 is counted among the S. suis serotypes causing clinical disease in pigs. Yet, limited information is available on this serotype. Here we determined for the first time the chemical composition and structure of serotype 3 capsular polysaccharide (CPS), a major bacteri...

A conformational study of some 2-[2’-(4′-substituted-phenylsulfinyl)-acetyl]-5-methylfurans 1–4 (OMe1, Me 2, H 3, Cl 4) was performed using IR carbonyl stretching and analysis supported by Natural Bond Orbital (NBO) and Polarisable Continuum Model (PCM) calculations at the B3LYP-D3/aug-cc-pVD...

Addition of elemental fluorine to 2,5-dihydrothiophene-1,1-dioxide (4) provided a mixture of isomeric 3,4-difluoro-2,3,4,5-tetrahydrothiophene-1,1-dioxides (5) in moderate yield. Photochemical chlorination of each of these isomers gave the same product mixture consisting mainly of trans-3-chloro...

Lipophilic arenediazonium salts dreived from 1-aminonaphthalene, 1-amino-4-bromonaphthalene, 1-amino-4-nitronaphthalene and 1-amino-9,10-anthraquinone were tested as titrants for determination of aromatic hydroxy compounds, amines, and compounds containing active methylene groups, usually at the...

It is important to establish an available analytical method for polycyclic aromatic hydrocarbons (PAHs), nitrated PAHs (nitro-PAHs), oxygenated forms of PAHs (oxy-PAHs), and hydroxy-PAHs (OH-PAHs) in sediment samples due to the fact that they co-exist in various environmental mediates, particula...

BackgroundErgosta-4,6,8(14),22-tetraen-3-one (ergone) has been proven to prevent the progression of renal injury and the subsequent renal fibrosis. We investigated the therapeutic effects and mechanism of ergone on a chronic renal failure model of rats induced by adenine.

Ergosta-4,6,8(14),22-tetraen-3-one (ergone) from many medicinal plants has been demonstrated to possess a variety of pharmacological activities in vivo and in vitro, including cytotoxic, diuretic and immunosuppressive activity. Metabolism and pharmacokinetic studies on rat were conducted for erg...

Ergosta-4,6,8(14),22-tetraen-3-one (ergone), isolated from the medicinal fungus Polyporus umbellatus, has been proven to prevent the progression of renal injury and the subsequent renal fibrosis.
