A series of copper(II) and zinc(II) complexes involving a tridentate O,N,O'-donor Schiff base derived from salicylaldehyde and beta-alanine {i.e. N-salicylidene-beta-alanine(2-), (L)}, having the composition [Cu(2)(L)(2)(H(2)O)].H(2)O (1), [Cu(L)(H(2)O)](n) (2), and [Zn(L)(H(2)O)](n) (3), have been prepared and characterized by elemental analyses,(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)
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 aim of this study was to describe the effects of Pycnogenol at various doses on preprandial and postprandial glucose levels, the levels of thiobarbituric acid reactive substances (TBARs) and N-acetyl-beta-d-glucosaminidase (NAGA) and on motor nerve conduction velocity (MNCV) in streptozotocin (STZ)-induced diabetic rats. Pycnogenol treatment (10, 20, 50(More)
The basic relationship between the chemical structure and pharmacological activities of new alkylesters of 4-[(2-hydroxy-3-alkylamino)propoxy]phenylcarbamic acids were evaluated. The efficiency of compounds was compared with those of metipranolol and practolol, respectively. The majority of 4-substituted derivatives of aryloxypropanolamines have shown(More)
The present paper links up with the study of principal pharmacological effects of newly synthesized aryloxyaminopropanols substituted with 1,4-piperazine derivatives in the hydrophilic moiety of the molecule. The substance with the working name IIIv showing the highest beta-adrenolytical and vasodilating effect underwent further pharmacological evaluations(More)
Synthesis of 2-{3-[4-(4-fluorophenyl)-1-piperazinyl]-2-hydroxy-propoxy}-phenylcarbamic acid alkylesters and in vitro evaluation of their beta-antiadrenergic and vasodilatative activities In effort to obtain effective compounds able to favourably influence pathologically changed cardiovascular functions, such as hypertension and ischemic cardiac disease, a(More)
A series of 8 new esters of 2-alkoxyphenyl-carbamoic acid were synthesized and assayed for local anesthetic activity. All compounds were isolated as hydrochlorides and their structure was proved by 1H-NMR 13C-NMR and IR spectroscopy. The index of anesthetic activity in infiltration and surface anesthesia proved that all prepared compounds are significantly(More)
During the course of study of variations in the basic moiety of heptacainium chloride 10 derivatives of 4-alkylpiperazinoethyl esters of o-heptyloxyphenylcarbamic acid were prepared. Pharmacological investigation indicated that practically all the new compounds were several times more active than standards (cocaine and procaine). The most effective compound(More)
