Synthesis of new stereoisomeric nitrate esters derived from isosorbide-mononitrates
(Freund Publishing House Ltd, London, 2001)
A synthesis of diastereomeric (7R) 7-endo-nitrooxy-3-oxo-2,5,9-trioxabicyclo[4.3.0]nonane (4b) and (7S) 7-exo-nitrooxy-3-oxo-2,5,9-trioxabicyclo[4.3.0] (7b) is described using D-glucitol as a starting compound. Bicyclic ...
Derivative spectrophotometric method for determination of acidity constants of single step acid-base equilibria
(Elsevier Science BV, Amsterdam, 2001)
A general derivative spectrophotometric method for determination of acidity constants is developed. The method appears suitable in cases when classical spectrophotometry cannot be employed due to little differences in the ...
Thin-layer chromatography of several antihypertensive drugs from the group of angiotensin converting enzyme inhibitors / Tankoslojna hromatografija nekih antihipertenziva iz grupe angiotenzin konvertujućih enzim inhibitora
(Srpsko hemijsko društvo, Beograd, 2001)
A rapid and simple method for the chromatographic separation of pharmacologically active components contained in some antihypertensive drugs has been developed employing thin-layers of silica gel and polyacrylonitrile ...
The high-performance thin-layer chromatographic determination of dexamethasone and xylometazoline in nasal drops containing different preservatives
(Springer Nature, 2001)
A simple and reliable HPTLC method has been developed and validated for the determination of dexamethasone (as the sodium phosphate salt) and xylometazoline (as the chloride). Assay of the compounds was performed on silica ...
