Solvent effects on pKa values of some substituted sulfonamides in acetonitrile-water binary mixtures by the UV-spectroscopy method
(2009)The examination of the dissociation constants of sulfonamides is essential in drug-design studies and in explaining the biopharmaceutical properties of substances. The dissociation constants of ten common human and veterinary ... -
Study of asymmetric aldol and Mannich reactions catalyzed by proline-thiourea host-guest complexes in nonpolar solvents
(2013)A proline-thiourea host-guest complex has been described as a good catalyst for asymmetric reactions such as aldol and Mannich reactions. High stereoselectivities were obtained under optimal conditions. Thiourea was observed ... -
Synthesis, characterization of poly-2- (2-hydroxybenzylideneamino)-6- phenyl-4,5,6, 7-tetrahydrobenzo[b]thiophene-3-carbonitrile: Investigation of antibacterial activity and optical properties
(2012)The oxidative polycondensation reaction conditions of 2-(2- hydroxybenzylideneamino)-6-phenyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3- carbonitrile were examined. The magnitude of the reflectance of the polymer decreases ... -
Tetraaquabis(orotato-O)cobalt(II) dihydrate
(2010)In the title CoII complex, [Co(C5H3N 2O4)2(H2O)4]·2H2O, the CoII ion is located on an inversion center and is coordinated by two orotate (2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate) anions and four water mol-ecules ... -
Validated electroanalytical and RP-LC assay of ertapenem in its pharmaceutical dosage form
(Editions de l'Academie Republique Populaire, 2013)Ertapenem is a member of carbapenem group beta-lactam antibiotics. The electrochemical behavior of ertapenem at the surface on a boron-doped diamond electrode is described. It is investigated and determined using cyclic, ... -
A validated stability-indicating RP-LC method for the simultaneous determination of amlodipine and perindopril in tablet dosage form and their stress degradation behavior under ICH-recommended stress conditions
(2013)A stability-indicating RP-LC assay method was developed for the simultaneous determination of the cardiovascular drugs amlodipine and perindopril in the presence of degradation products generated from forced decomposition ...
