The preliminary study of biosynthesis sulphur-35 amino acids labelled compounds has been done using wild strain of Baker's yeast Saccharomyces cerevisiae as producer mycroorganism and the solution of Na35SO4 (45 mCi/60 L) as tracer source was added into the salt media, in which the incorporation of S-35 radioisotope to the yeast cells was synthesized. Maximum incorporation of 93,5 % was obtained after 10 hours incubation at 30 C. Hydrolysis was carried out using HCl 6N and heating at 110 C for 18 hours to destroy the yeast cells, therefore L-35-methionine and the other amino acids would dissolve in the solution. Hydrolisate isolation was exhibited using two step of coloumn chromatographic using Dowex-cation exchanger resin as stationary phase and the demineralized steril water containing 0, 1 % -mercapto ethanol (ME) and the mixing of water: HCl 4N which contains 0, 1% ME as mobile phase. The ratio volume of these both mobile phases were gradually adjusted. Purified amino acids the was analysized using paper chromatography method. The result shows that the 7th fraction of eluate contained L.35S-methionine biosynthesized by yeast Saccharomyces cerevisiae, that had high radiochemical purity (100 %) and the radioactive concentration of L-35S-methionine was 28 mCi/ml.Key-words: amino acids, biosynthesis, sulphur-35, L-35-S-methionine.

Gastroretentive dosage forms extend significantly the period of time over which the drug may be released. This prolonged gastric retention improves bioavailability, decrease drug waste and improve solubility of drugs that are less soluble in a high pH environment due to their availability in gastric pH for longer duration of time.Floating drug delivery systems have a bulk density less than gastric fluids and hence remain buoyant in the stomach. The main objective of the present study was to develop Gastroretentive (GR) controlled release ormulations of Metoprolol to prolong the gastric retention time so that its bioavailability can be improved. The formulations were prepared by using swellable polymers like HPMC K4M, HPMC K15M, HPMC K100M, Guar Gum, Xanthan Gum, Sodium carboxymethyl cellulose and various effervescent compounds, e.g. sodium bicarbonate, and citric acid by the direct compression method. All the formulations were evaluated for different parameters like floating lag time, total floating time, hardness, weight variation, density measurements, drug content and water uptake/swelling index. Dissolution studies were done for all formulations in 0.1N HCl (pH 1.2). Formulations F3, F4 and F10 were found to provide maximum sustained release of metoprolol s uccinate up to 24 h with optimum floating properties.Key words : Controlled release; Gastro retentive; HPMC; Guargum; Xantham gum

Identification of solid state interaction between TMP and SMZ by hot contact method Kofler and crystallization reaction had been carried out. The results of hot contact method Koflershown formation a new crystalline habit as long and thin needle shaped on contact zone (mixing zone) between Solid TMP and SMZ. It had a different melting point in compared to its single component. Crystallization reaction between two of supersaturated solution of component TMP and SMZ in methanol solvent also indicated the growth of crystal habit as similar as hot contact method Kofler. Solid state interaction between TMP and SMZ was confirmed by microscopic SEM, powder X-ray diffraction, and thermal DSC. Microscopic analysis by SEM showed significantly the change of habit and morphology of crystal as long and thin needle shaped. New powder X-ray diffraction (PXRD) interferences peaks were observed in addition to PXRD interference peaks of each component that proved formation of cocrystalline phase. Thermogram DSC indicated a new endothermic peak corresponding to melting point of a new cocrystalline phase at temperature 178,82 °C.Key words : trimethoprim, sulfamethoxazole, physical interaction, cocrystalline phase

Biofilm formation and the expression of icaA gene can be induced by environment conditions that are potentially toxic for bacterial cells. The effect of green flies maggots secretion to biofilm was studied some years ago to investigate in vitro effect of secretion of Chloroprocta sp. maggots on the formation of Staphylococcus epidermidis biofilm (phenotype) and the expression level of icaA gene (genotype) for indicating its mechanism on bacterial biofilm eradication. Microtiter plate biofilm assay was used to measure the effect of Chloroprocta sp. maggots secretion at various concentration on S. epidermidis biofilm. The expression level of icaA gene was performed by Real TimePCR using lightcycler method. The biofilm susceptibility test was done against maggots excretion/secretion using MTT assay. Whereas planktonic susceptibility testing was carried out using Kirby Bauer method. In the presence of maggots secretion at low concentration (5%), biofilm formation of S. epidermidis 734 was induced. In contrast, the expression level of icaA gene in production of maggots excretion/ secretion at concentration of 5% was lower than that of without maggots secretion (1/2 Fold). Eradication of bacterial biofilm was demonstrated after 48h incubation (MD=-0,011;P<0,05), but planktonic cell. In vitro difference effect of the Chloroprocta sp. maggots secretion at low concentration to phenotype and genotype of S. epidermidis biofilm showed that the possibility of maggots secretion ability to eradicate bacterial biofilm was not mainly due to the expression level of icaA gene.

Synthesis of thiazol derivative compounds from Î±-bromo asil bromida and thiourea ., Tjiptasurasa
Indonesian Journal of Pharmacy Vol 16 No 3, 2005
Publisher : Faculty of Pharmacy Universitas Gadjah Mada, Yogyakarta, Skip Utara, 55281, Indonesia

Thiazol compounds are mostly used as therapeutics in varies effects. These compounds could be synthesized from starting materials that had been produced by local agrochemical industries i.e. alcohol (from the alcohol factories) and urea (from the fertilizer factory). Yielded bromacylbromide could be used to acylate urea derivatives to form aliphatic bromacylurea. When thiourea was used the cyclization product happened i.e. occurred thiazolon derivatives (without bromine). The lost of bromine could be detected by losing of cluster peak of bromine isotope on MS-spectra. The products of these processes were pure, there were 2-aminothiazol- 4-one 2-amino-5-methyl-thiazol-4-one and 2-amino-5-ethyl-thiazol-4-one. Key word : alcohol, thiourea, aminothiazol-4-one.
