Salt effects in electromembrane extraction.

J. Chromatogr. A. 1347 , 1-7, (2014)

Electromembrane extraction (EME) was performed on samples containing substantial amounts of NaCl to investigate how the presence of salts affected the recovery, repeatability, and membrane current in the extraction system. A group of 17 non-polar basic drugs ...

Antiallergic and antiasthmatic effects of a novel enhydrazinone ester (CEE-1): inhibition of activation of both mast cells and eosinophils.

J. Pharmacol. Exp. Ther. 350(2) , 444-54, (2014)

Activation of mast cells and eosinophils is a fundamental process in the pathophysiology of allergic diseases. We have previously reported that the novel enhydrazinone ester CEE-1 (ethyl 4-phenylhydrazinocyclohex-3-en-2-oxo-6-phenyl-1-oate) possesses potent a...

A screen of approved drugs and molecular probes identifies therapeutics with anti-Ebola virus activity.

Sci. Transl. Med. 7 , 290ra89, (2015)

Currently, no approved therapeutics exist to treat or prevent infections induced by Ebola viruses, and recent events have demonstrated an urgent need for rapid discovery of new treatments. Repurposing approved drugs for emerging infections remains a critical ...

Development and validation of an ultra-performance liquid chromatography method for simultaneous analysis of 20 antihistaminics in dietary supplements.

Biomed. Chromatogr. 29(3) , 465-74, (2015)

The purpose of this study was to develop and validate an ultra-performance liquid chromatography method for simultaneous analysis of 20 antihistamines (illegal additives) in dietary supplements. The limits of detection and quantitation of the method ranged fr...

Evaluation of the separation mechanism of electrokinetic chromatography with a microemulsion and cyclodextrins using NMR and molecular modeling.

Electrophoresis 32(21) , 3062-9, (2011)

Electrokinetic chromatography (EKC) allows the separation of closely related substances by the detection of fine effects in analyte-separation system interactions. With the goal of understanding the fine effects involved in separation using a dual cyclodextri...

Utility of 4-chloro-7-nitrobenzofurazan (NBD-CI) for the Spectrophotometric and spectrofluorometric determination of several antihistamine and antihypertensive drugs.

J. AOAC Int. 96(5) , 968-75, (2013)

New, sensitive, and selective spectrophotometric and spectrofluorometric methods have been developed for determination of clemastine hydrogen fumarate (Clem), loratadine (Lor), losartan potassium (Los), and ramipril (Ram) in both pure form and pharmaceutical ...

A randomized trial of icatibant in ACE-inhibitor-induced angioedema.

N. Engl. J. Med. 372(5) , 418-25, (2015)

Angioedema induced by treatment with angiotensin-converting-enzyme (ACE) inhibitors accounts for one third of angioedema cases in the emergency room; it is usually manifested in the upper airway and the head and neck region. There is no approved treatment for...

Identification and determination of selected histamine antagonists by densitometric method.

Acta Pol. Pharm. 70(1) , 19-26, (2013)

The conditions for identification were determined for four histamine antagonists: clemastine fumarate, loratadine, cetirizine dihydrochloride and desloratadine by TLC (thin-layer chromatography) method. The selected chromatographic conditions were used to dev...

The antihistamines clemastine and desloratadine inhibit STAT3 and c-Myc activities and induce apoptosis in cutaneous T-cell lymphoma cell lines.

Exp. Dermatol. 22(2) , 119-24, (2013)

Mycosis fungoides and its leukaemic counterpart Sézary syndrome are the most frequent cutaneous T-cell lymphomas (CTCL), and there is no cure for these diseases. We evaluated the effect of clinically approved antihistamines on the growth of CTCL cell lines. C...

Dual CD system-modified MEEKC method for the determination of clemastine and its impurities.

Electrophoresis 31(19) , 3296-304, (2010)

A dual system of CDs was used for the first time in MEEKC with the aim of determining clemastine and its three main related impurities in both drug substances and tablets. The addition of methyl-β-cyclodextrin and heptakis(2,6-di-O-methyl)-β-cyclodextrin to t...
