JOURNAL FREE ACCESSA three-compartment in vitro transport model, consisting of two aqueous compartments (buffered at pH 1.2 and 7.4) separated by a thin, olive oil-impregnated Millipore membrane, was employed to study the transport kinetics of four drugs in the absence and presence of the complexing agent, caffeine. The test drugs under investigation were salicylic acid, acetylsalicylic acid, dehydroacetic acid, and ethyl p-hydroxybenzoate. The apparent first-order transfer rate constants obtained for the drugs alone were found to correlate well with reported in vivo apparent first-order absorption rate constants. In the presence of caffeine the rate of transfer of all of the test drugs was significantly reduced. Calculated in vitro transport rate constants were found to correlate well with reported in vivo absorption rate constants for the drug-caffeine complexes.View full abstractDownload PDF (739K) -

JOURNAL FREE ACCESSIn order to clarify the effect of the products formed during lipolysis by Mucor lipase, some experiments were done. The lipase was inhibited by soaps of long-chain fatty acids above C12, while the lipase was little affected by soaps of C4-C8 fatty acids, glycerin and monoglycerides. Long-chain fatty acids in very low concentration, less than 5 μmoles, acted as a competitive inhibitor. Although diffusion of oleic acid from the interface was arrested by laurate and oleate because of the accumulation of the salts at the interface, by the addition of bile salt to the system diffusion of oleic acid was promoted. Bile salts reduced inhibition by long-chain fatty acids, consequently the initial rate of the reaction did not reduce for some time. Ca2+ also prevented the inhibition by removing the fatty acids into the oil phase after the formation of Ca-soaps.View full abstractDownload PDF (762K) -

JOURNAL FREE ACCESSOn treatment of some C-and O-D-glucopyranosides with diazomethane in methanol or in methanol-dimethylformamide mixture, a partial methylation of the sugar moiety took place, though to a slight extent, to give a mixture of methyl ethers, in which 3-methyl ether is the major. The reaction is much favored in the presence of a small amount of stannous chloride. A O-α-D-glucopyranoside gave almost exclusively the corresponding 3-methyl ether of the glucose residue, while the β-anomer provided, beside 3-methyl ether, 2, 3-dimethyl ether nearly in equal amount. The benzylidene derivatives of O-α-and β-D-glucosides gave also the corresponding 3-methyl ether but 2, 3-dimethyl ether was formed only in trace and, instead, 2-methyl ether was provided.View full abstractDownload PDF (1167K) -

JOURNAL FREE ACCESSMercury (II) is able to quench the fluorescence of Rhodamine B in the presence of potassium iodide. The quenching was affected by pH of the solution and the concentration of potassium iodide, but not markedly by several anions. The degree of quenching was closely correlated with mercury (II) concentrations at the fixed concentrations of the dye and potassium iodide, so that mercury (II) can be fluorometrically determined in this method. Cystline and egg albumin protected the quenching by mercury (II) in the presence of potassium iodide. The fluorescence of Rhodamine B was not quenched by organic mercury (II) compounds in the presence of potassium iodide. Fluorescence of the dye was also quenched by some metal ions, such as bismuth (III), thallium (III), palladium (II) and platinum (IV) in the presence of potassium iodide.View full abstractDownload PDF (582K) -

JOURNAL FREE ACCESSThis study was initiated to study on the relationship between the chelate formation and the detoxication activity of penicillamine against heavy metal poisoning. The equilibrium of acid dissociation and the mode of the coordination of metal chelates were investigated by means of potentiometric titration, ultraviolet-visible spectra and proton magnetic resonance spectra. The equilibrium constants among various chemical species of penicillamine in aqueous solution were determined and the results were comparable with those in cysteine. The mode of coordination between penicillamine and metal ions was deduced through the comparison of the formation constants and the absorption spectra of the metal chelates of penicillamine with those of the related compounds. In the chelates produced from penicillamine with Co2+, Zn2+ and Ni2+, the coordination occurs through sulfur and nitrogen atoms while the carboxyl group remains off in coordination, and in the chelates produced from penicillamine with Hg2+, Cd2+ and Pb2+, sulfur, nitrogen and also oxygen atoms contribute to the coordination. The investigation by proton magnetic resonance spectroscopy in an aqueous solution gave more reliable information for the coordination of carboxyl group in penicillamine toward Hg2+, Cd2+ and Pb2+.View full abstractDownload PDF (783K) -

JOURNAL FREE ACCESSBased on the experimental observations that the concentrations of ionized and unionized molecules of sulfonamides at the bacteriostatis are linearly related to the drug's pKa, equations of the relation of pKa to bacteriostatic activity of sulfonamides against Escherichia coli are proposed. The optimal acid dissociation constant, pKa0, of sulfonamides which are active at a minimum concentration is calculated. pKa0 and the minimum bacteriostatic concentration are found to change with changes of pH of culture media.View full abstractDownload PDF (551K) -

JOURNAL FREE ACCESSHydrophobicity constant π, which was introduced by Hansch, of sulfonamides was measured in the systems of n-octyl alcohol-water (designated π0) and chloroform-water (designated πc). A good linear correlation was obtained between π0 and πc. πc could be expressed in terms of log Sw, solubility of unionized molecules in water, and log Sc, solubility in chloroform. Binding of sulfonamides to human plasma protein, rabbit plasma and rabbit blood was measured following an equilibrium. dialysis method. A good correlation was obtained in any couple of the three measurements. The protein binding was found to be subjected to molecular weight of sulfonamides. Thus, an analysis was performed of the structure-activity relationship of sulfonamides between the bacteriostatic activity against Escherichia coli and the drug's physicochemical parameters including molecular weight.View full abstractDownload PDF (623K) -

JOURNAL FREE ACCESSThe influence of a non-ionic surface active agent on the dissolution rate of benzoic and salicylic acids has been investigated and dissolution mechanisms have been examined as a function of the hydrodynamics of the system. Clearly, the dissolution rate of a solid in a micellar solution is not proportional to the solubility of the compound in the dissolution medium. Evaluation of dissolution rate data and theories has led to the conclusion that, depending upon hydrodynamic conditions, the dissolution rate of a solid will be proportional to the effective diffusion coefficient raised to a power between 0.5 and 1.0.View full abstractDownload PDF (924K) -

JOURNAL FREE ACCESSSalting behavior of alkylxanthines, other cyclic amides, and cyclic conjugated ketones was investigated by the solubility, partition, and permeation methods. These compounds were found to be salted-out by tetramethyl-and tetraethylammonium salts against the common belief that nonelectrolytes are salted-in by these salts. The above compounds were, however, salted-in by large ammonium salts and the effect was attributed to complex formation between the large ammonium ions and the nonelectrolytes. Salts were also shown to affect equilibrium concentrations of nonelectrolytes across a lipoid membrane and the rate of permeation of nonelectrolytes through the membrane.View full abstractDownload PDF (773K) -

JOURNAL FREE ACCESSThe N-3→N-9 ribosyl (hydrogen halides or mercuric halides catalyzed) migration of N6-acyl derivatives of 3-β-D-ribofuranosyladenine and its 5'-phosphate and 3-β-D-glucopyranosyladenine was found to occur by an intermolecular mechanism. Furthermore, formation of the 3-and 9-ribosyl derivatives was confirmed in the ribosylation reaction of N6-benzoyladenine or its chloromercuri salt using milder conditions. These facts, contrary to the reports which described that the 9-glycosyl derivatives alone could be isolated, suggest that the reaction of N6-benzoyladenine or its chloromercuri salt with glycosyl halides result in the initial formation of the 3-glycosyl derivatives followed by rapid conversion to the thermodynamically more stable 9-glycosyl derivatives in the presence of hydrogen halides or mercuric halides.View full abstractDownload PDF (978K) -

JOURNAL FREE ACCESSFormation of new mixed ligand chelates consisting of penicillamine, bivalent metals, such as mercury, lead and cadmium, and some of the secondary ligands, such as mercaptoacetic acid, N-acetylpenicillamine, glutathione, 2-mercaptoethylamine, α-mercaptopropionyl glycine and penicillamine methyl ester, in the ratio of 1 : 1 : 1 were recognized potentiometrically, but there was no indication for the existence of the similar mixed ligand chelate in the cases of ethylmercaptan, glycine and histidine. The mixed ligand chelate is formed in two steps ; the simple penicillamine metal chelate is formed in the first step, and the secondary ligand becomes to coordinate to 1 : 1 penicillamine chelate to yield the 1 : 1 : 1 mixed ligand chelate in the second step. The order of the relative formation constants of mixed ligand chelates was Cd2+>Hg2+>Pb2+. The formation constants of mixed ligand chelates are linearly correlated to the dissociation constants of sulfhydryl group in secondary ligands. Moreover, among these mixed ligand chelates, the decrease of binding affinity of the carboxyl group in penicillamine tends to increase the formation of the mixed ligand chelate.View full abstractDownload PDF (598K) -

JOURNAL FREE ACCESSThe ionization constants of 2-aminoethylisothiuronium (AET) and 3-aminopropylisothiuronium (APT) salts, dibasic acid intrinsically, were determined potentiometrically. Those isothiuronium salts were extremely unstable and underwent the transguanylation, during the titration, through the conjugate base to the sulfhydryl compounds, which were ionized in the second step. For the determination of the ionization constant, the titration curve was treated as an equimolar mixture containing two acids. From the temperature dependence of the ionization constant, measured at 5°, 15°, 25° and 35°, was calculated the enthalpy of the ionization, which led to the evaluation of the entropy. The thermodynamic functions of those compounds at 25° were as follows : [table] The thermodynamic functions for the transguanylation and the cyclization products from those isothiuronium salts were also determined.View full abstractDownload PDF (565K) -

JOURNAL FREE ACCESS1, 2 : 3, 4-Di-O-isopropylidene-α-D-galacto-hexodialdo-1, 5-pyranose (4) was treated with sodium cyanide in aqueous methanol and the resulting cyanohydrin mixture (5a and 6a) was tosylated to give 1, 2 : 3, 4-di-O-isopropylidene-6-O-tosyl-L-glycero-(5b) and-D-glycero-α-D-galacto-heptopyranurononitrile (6b). Lithium aluminum hydride reduction of these tosylates 5b and 6b, followed by acetylation yielded D-glycero-N-acetylepimine (7a) and L-glycero-N-acetylepimine (8), respectively. The D-glycero-epimer (7a) thereby obtained was treated in warm acetic acid and gave a 6-acetamido-7-O-acetate (17a) exclusively, whose deacetylation with sodium methoxide yielded a 7-deacetyl derivative (19). Pfitzner-Moffatt oxidation of 19, followed by treatment of the resulting 7-oxo derivative (20) with methylmagnesium bromide gave 6-acetamido-6, 8-dideoxy-1, 2 : 3, 4-di-O-isopropylidene-L-threo-α-D-galacto-octopyranose (26). The latter (26) was converted into its D-erythro-derivative (24) by oxidation with chromium trioxide in pyridine and successive reduction with sodium borohydride. Hydrolysis of 24 with aqueous acetic acid or Amberlite IR-120 (H+) gave the N-acetate of lincosamine which constitutes a sugar component of antibacterial antibiotic, lincomycin.View full abstractDownload PDF (1517K) -
