AbstractAbstract
[en] Present article discusses the optimal method for synthesis of amino acid derivatives of acetyl salicylic acid. The optimal method for synthesis of amino acid derivatives of acetylsalicylic acid has been developed. It has been shown that the method of activated esters is the best for obtaining the amino acid derivatives of acetylsalicylic acid. (author)

AbstractAbstract
[en] Increasing interest and current trends for natural materials with various health beneficial functions by radiation (RT)-biotechnology (BT) fusion by developed countries. However, the information and development of new functional materials using the RT-BT fusion technology is still limited. The target material developed and manufactured by RT-BT fusion technology may have a multi-functional effect on human health and it can be applied for pharmaceutical materials as well as functional food ingredient. The market of functional new materials has been grown dramatically and a multi-functional material manufactured by RT-BT fusion technology may have a great economic impact for both the domestic and overseas market. Development of GA-CLA ester by chemical synthetic method. Transformation of linoleic acid to conjugated linoleic acid by irradiation. Identification and confirmation of the biological functions including antioxidative, cancer cell proliferation inhibition, anti-microbial, enhancement of immune response and lipid metabolism of GA-CLA ester. Increase industrial applicability of the new materials. Development of GA-CLA ester by chemical synthetic method(2 patents submitted). Development of the optimum methodology of GA-CLA and its derivative, octadeca-9,12-dienyl-3,4,5-trihydroxy benzoate). Identification and confirmation of biological activities of GA-CLA. Extramural funding from the Ministry of Commerce, Industry, and Energy subjected by gallic acid-fatty acid derivatives (205,000,000 Won). Provides the basic data for successful project 'Development of cosmeceutical and cosmetics using gallic acid fatty acid derivatives' funded by Ministry of Commerce, Industry, and Energy and collaboration with the Technology-invested venture company, SunBiotech, Co. and problem-solving for industrial application.

AbstractAbstract
[en] The present investigation concerns the experimental design in preparing a solid dispersion of ionized carvedilol with hydroxypropyl-β-cyclodextrin (HPβCD), tartaric acid (TA) by adopting 'kneading technique'. Simplex lattice design has been chosen to develop model equations that correlate the process variables such as HPβCD (mg), TA (mg), and kneading time (min) with the response variables, such as solubility (mg/mL) and drug release (%) from the solid dispersion. Software-generated ANOVA results confirmed the sufficiency of model equations. Results predicted by model equations are in good agreement with that of experimental results. Optimized formulation with variables 'CV: HPβCD: TA-kneading time' (200mg: 689.6mg: 227.6mg-45 min) showed complete drug release (⁓99%) within 15 min and enhanced solubility of 1.89mg/mL. The instrumental analysis (DSC, XRD and FTIR) of the optimized solid dispersion suggests a transformation of crystallinity of drug to amorphous form, due to its complexation with HPβCD. Hence, this combination of drug and carriers suggests an improvement of carvedilol bioavailability

AbstractAbstract
[en] Simple, selective and precise four spectrophotometric methods were developed and validated for quantitative determination of Salicylamide (SAD) and Ascorbic acid (ASC, Vitamin C) in their binary mixture. Method A is Area under curve spectrophotometry, in which the area under curve in the wavelength ranges 225-245 nm and 265-285 nm were selected for determination of SAD and ASC. Method B is based on dual wavelength spectrophotometry, where ASC can be determined by difference in absorbance at 249.8 and 285.8 nm. On the same way; SAD is measured by difference in absorbance at 240.4 and 286.4 nm. Method C utilizes isoabsorptive point spectrophotometry where total concentration of SAD and ASC was calculated at their isoabsorptive points at 246.4 and 287 nm, while SAD concentration alone can be determined by first derivative spectrophotometry (1D) at 315.4 nm, then ASC concentration can be determined by subtraction. Method D is ratio subtraction spectrophotometry, where ASC can be determined by dividing the spectrum of the mixture by the spectrum of the SAD (as a divisor) followed by subtracting the constant absorbance value of the plateau region, then finally multiplying the obtained spectrum by the spectrum of the divisor. The developed methods have been successfully applied for determination of the studied drugs in different laboratory prepared mixtures and in their pharmaceutical formulation. Statistical comparison between the results obtained by applying the proposed methods and the reported HPLC method was done, and it was found that there was no significant difference between them regarding both accuracy and precision.

AbstractAbstract
[en] Ultraviolet and gamma irradiation were used to induce mutation of Aspergillus niger ATCC 11414 in order to increase ability of citric acid production. Five mutants of high-producing citric acid were 7UV-18, A2-14, 9UV-2, 9UV-27 and 8UV-10. The yields of citric acid were 2.0 to 3.84 fold higher than that of the wild type strain
