A series of twenty substituted 2-hydroxy-3-[(2-aryloxyethyl)amino]propyl 4-[(alkoxycarbonyl)amino]benzoates were prepared and characterized. As similar compounds have been described as potential antimycobacterials, primary in vitro screening of the synthesized carbamates was also performed against two mycobacterial species.(More)
The basic relationship between chemical structure and pharmacological activity of eight newly developed potential ultrashort-acting beta-adrenergic blockers was evaluated. The compounds studied are derivatives of arylcarbonyloxyaminopropanols and were prepared by four-step synthesis. All the compounds evaluated showed weak antiisoprenaline (beta-adrenergic(More)
The antiarrhythmic action of the newly developed compound 44Bu (an original compound that was synthesized at our Faculty of Pharmacy) was tested on a model of aconitine-induced arrhythmia and compared with the effect of lidocaine. Both tested substances were administered either as therapeutic or prophylactic agents. 44Bu was highly effective in reducing the(More)
Five new 3-(4-arylpiperazin-1-yl)-2-hydroxypropyl 4-propoxybenzoates were designed and synthesized as potential dual antihypertensive agents. The compounds were prepared as free bases and subsequently transformed to hydrochloride salts. The position of protonation of nitrogen atoms in the piperazine ring of hydrochloride salts was determined by means of(More)
Nine new dihydrochloride salts of 3-(4-arylpiperazin-1-yl)-2-hydroxypropyl 4-alkoxyethoxybenzoates were designed and synthesized. The physicochemical properties such as lipophilicity index (log kw) and dissociation constant (pKa) were experimentally determined and compared to the software calculated data. The lipophilicity index was determined by means of(More)
Sphingosine kinase 1 (SphK1), the enzyme that produces the bioactive sphingolipid metabolite, sphingosine-1-phosphate, is a promising new molecular target for therapeutic intervention in cancer and inflammatory diseases. In view of its importance, the main objective of this work was to find new and more potent inhibitors for this enzyme possessing different(More)
The present paper deals with a complex spectral and physicochemical evaluation of mono[{3-[4-(2-etoxyetoxy)-benzoyloxy]-2-hydroxypropyl}-isopropylammonium]fumarate, a potential ultrashort acting beta1-blocker. The identity of the substance under study (labelled as UPB-1) was confirmed by 1H- and 13C-NMR spectra as well as IR spectrometry. The determined(More)
With the use of normotensive laboratory Wistar strain rats, changes in heart rate induced by three newly synthesized potential ultrashort beta-blockers were tested. The animals were administered the tested substances intravenously in general anesthesia. In all animals, heart rate was measured at predetermined time intervals. All obtained values were(More)
The paper is devoted to the synthesis and study of some physico-chemical properties of a group of substances--potential antagonists of beta-adrenergic receptors. The substances are derivatives of aryloxyaminopropanol, where the basic part consists of diphenylmethylpiperazine and the aromatic part is modified with alkyl esters (methyl to butyl) of carbamic(More)
