JOURNAL FREE ACCESSEven if a random distribution of particles has been achieved in the practical process, a precise quantity of an active ingredient in individual dose units can not be always assured. This variation in the potency is attributed to a problem of mixing and related directly to the sampling error. Theoretical consideration indicates that the variance in the proportion of an active ingredient developed through sampling from a randomized bulk mixture is calculated with the following equations ; 1. When the shape of particles is spherical [numerical formula] 2. When the shape of particles is cubic [numerical formula] where, P is the proportion of an active ingredient, g the sample weight, dA and dB are the the densities of components, LA and LB the mean volume diameters of components, σA and σB the standard deviations of particle-sizes distributions of components ; suffix A means the active component. The possible application of the result to suspension and emulsion has been discussed.View full abstractDownload PDF (632K) -

JOURNAL FREE ACCESSA structual study of so-called dihydrocompound and tetrahydrocompound of 10H-pyridazino (3, 2-b) quinazolin-10-one (VI) was described. These two compounds were assigned to be 3, 4-dihydro- and 1, 2, 3, 4-tetrahydro-10H pyridazino (3, 2-b) quinazolin-10-one (III, IV), respectively. Catalytic hydrogenaytion of VI and III revealed that while the former gave II, III, IV and IX, the later gave II and IX.View full abstractDownload PDF (519K) -

JOURNAL FREE ACCESSα-Methylpantethine, β-methylpantethine, homopantethine and oxypantetheine did not support the growth of L. bulgaricus B1 which required pantethine for its growth. These pantethine analogs were competitive inhibitors of pantethine in this microorganism, but they stimulated the bacterial growth at their subinhibitory concentrations in the presence of a small amount of pantethine. Magnitudes of their inhibitory effects were in the order of oxypantetheine≥homopantethine>β-methylpantethine>α-methylpantethine on the molar basis of the reduced form.View full abstractDownload PDF (515K) -

JOURNAL FREE ACCESSIn order to study the enzymatic properties of α-amino acylase of KT 801 (Pseudomonas sp.), which has δ-ornithine acylase, purification of the α-amino acylase have been attempted. α-Amino acylase of KT 801 was extracted by means of spheroplast formation and purified by fractionation with ammonium sulfate, acrinol treatment, and CM Sephadex chromatography. The specific activity of the purified enzyme toward N-benzoyl-L-alanine was 2500 μM/hr/mg and it was represented about 70 fold purification over the original cell suspension. This enzyme has a pH optimum around 8.0 toward benzoyl-L-alanine. It has an optical specificity and hydrolyzes benzoyl-L-amino acids. Also, it hydrolyzes α-N-benzoyl-L-amino acids but not phenylacetyl amino acids. The ratio of the activities toward α-N-benzoyl amino acids remained constant all through the purification steps except for 2-N-benzoyl-L-ornithine. These results suggest that one enzyme hydrolyze these α-N-benzoyl amino acids. Then, the α-amino acylase of KT 801 was provisionally named "benzoylamino acid amidohydrolase."View full abstractDownload PDF (847K) -

DL-Homomethionine (2-14C, 15N) was directly incorporated into sinigrin in comparison with the other labelled compounds, however DL-allylglycine (2-14C, 15N) was incorporated insignificantly and DL-methionine (2-14C), sodium acetate (2-14C) and sodium malonate (2-14C) were incorporated without randomization. The relationships of their efficient precursors were discussed on sinigrin biosynthesis.

JOURNAL FREE ACCESSHydrolysis of pentaacetylgitoxin (I) with diastase gave selectively 3', 3'', 3''', 16-tetraacetylgitoxin (IIa) as a main product. When IIa was treated with potassium hydrogen carbonate, acetyl groups were successively eliminated in the order of those at C-3''', -16, -3'' or -3' positions to afford 3', 3'', 16-triacetylgitoxin (IIc), 3', 3''-diacetylgitoxin (IId), 3'-monoacetylgitoxin (acetylgitoxin-γ, IIe) and gitoxin (IIf). These partial acetates did not agree with those obtained in acetylation of gitoxin (IIf), in which acetyl groups were introduced in the order at C-4''', -16, -3''' or -3' positions. The partial acetates obtained by the former method (deacetylation) were thought to be more essential for the study of metabolism of I than those prepared by the latter method (acetylation).View full abstractDownload PDF (730K) -

JOURNAL FREE ACCESSRadioactive sodium 5-acetamido-2, 4, 6-triiodo-N-methyl-isophthalamate (131I) was synthesized by isotopic exchange reaction in acidic aqueous solution. When this compound was injected intravenously into rabbit, it was excreted very rapidly and little of it was taken up by organs except kidney. The blood clearance of the compound obtained by external counting after the single injection was exponential after a certain period of equilibrium and its rate was independent of the administered dose. Those results indicate that this substance is filtered at the glomeruli passively and the half clearance time can be considered to be a parameter of the renal glomerular filtration rate.View full abstractDownload PDF (440K) -

JOURNAL FREE ACCESSEffect of the pretreatment with tolbutamide in female rats on the liver microsomal activation (anticholinesterase activities) and degradation (formation of p-nitrophenol) of parathion was studied. Both pathways were stimulated by tolbutamide-pretreatment, but the degradation process was superior to the activation of parathion at lower concentration of substrate in the liver preparation of rats pretreated with tolbutamide. The formation of p-nitrophenol from paraoxon by liver homogenate was also accerelated by tolbutamide. These facts should be reflected in the lowering of parathion toxicity in animals pretreated with tolbutamide.View full abstractDownload PDF (653K) -

Gas chromatographic method was superior to fluorometry as regards selectivity. Each catecholamine was analysed simultaneously and the whole pattern of chromatogram permitted a rapid, simple diagnostic evaluation. Moreover the resolving power of gas chromatography led to a finding of a co-existing unknown substance, which had the identical retention time to dopa and existed in a significant amount in normal urine, as well as in the urine of a patient with pheochromocytoma.View full abstractDownload PDF (494K) -

JOURNAL FREE ACCESSEffect of 1 : 1 complex formation with a nonabsorbable drug (A) and an absorbable one (B) on the absorption of B from rat small intestine according to the recirculating perfusion method in situ was described. The combination of drugs used as the model compounds was riboflavin phosphate (A)-sulpyrin (B), riboflavin phosphate (A)-caffeine (B), riboflavin phsophate (A)-4-aminoantipyrine (B), aminopropylon (A)-sulfamethizole (B), and aminopropylon (A)-sulfisomidine (B). The absorption rate constant of B was influenced by the incorporation of A and the rate was shown to be slowed and dependent on the concentration of A. The effect was rationalized and effectively quantitated by hypothesizing that the complex AB was absorbed little or not absorbed, and that only the noncomplexed form of the absorbable drug was observably absorbed. Complexation of B with A decreased the apparent partition coefficient of B. It is thought that this suggests one possible mechanism for the absorption of complex.View full abstractDownload PDF (734K) -
