The paper presents the study of some physicochemical properties of 2-, 3-, 4-alkoxyphenylcarbamic acid derivatives with various substituted N-phenylpiperazin-1-yl moiety in the basic part of the molecule. Elemental analysis, melting point, solubility, surface activity, dissociation constant and some lipophilicity parameters i.e.--partition coefficient,(More)
PURPOSE OF REVIEW The aim of this review is to describe the pharmacology, toxicology and chemistry of the new group of local anesthetics of phenylcarbamic acid type. RECENT FINDINGS Basic esters of alkoxy-substituted phenylcarbamic acid have shown high local anesthetic potency, while maintaining a relatively safe toxicity profile. Their potency uniquely(More)
A group of 31 of alkoxy-substituted phenylcarbamic acids with the alkoxy group inortho, meta orpara position, and methyl or ethoxymethyl attached to the ethylene moiety in position 1, including both basic ethyl esters and derivatives branched on ethylene, were evaluated forin vitro antimycobacterial activity againstMycobacterium tuberculosis, M. kansasii,(More)
By pyrrolidinoethylalcohol addition on 2-, 3- and 4-alkoxy-substituted phenylisocyanate in non-aqueous toluene medium a series of 30 compounds of the type Pyrrolidinoethylesters of 2-, 3- and 4-alkoxy substituted phenylcarmabim acids were prepared. Pharmacological evaluation results shown after comparing with cocaine and procaine standards that these(More)
The review paper studies kojic acid, a secondary metabolite of fibrous fungi, as a carrier chemical structure of potential pharmaceuticals. The examined preparative procedures, physico-chemical and biologic properties, and especially the antifungal and antileukemic effects of the parent kojic acid indicate that novel potential drugs can be developed on its(More)
Purpose. The purpose of the present research was to study 10 m-alkoxysubstituted pyrrolidinoethylesters of phenylcarbamic acid—potential local anesthetics. The relationships between the structure of the molecule, its physicochemical parameters (log Doct, log k, RM, solubility) were correlated to the permeability data obtained from permeation experiments in(More)
The lipid bilayer thickness d(L), the transbilayer distance of lipid phosphate groups d(pp/inf> and the lipid surface area A(L) of fluid hydrated bilayers of lamellar phases of egg phosphatidylcholine or dipalmitoylphosphatidylcholine containing N-alkyl-N,N-dimethylamine N-oxides (CnNO), 1,4-butanedi-ammonium-N,N'-dialkyl-N,N,N',N'-tetramethyl dibromides(More)
The paper reviews recent developments in the use of molecularly imprinted polymers in several analytical techniques, such as solid-phase extraction, liquid chromatography, capillary electrophoresis, capillary electrochromatography, and as selective sorbents in chemical sensors. Molecular imprinting is achieved by the interaction between complementary groups(More)
