약학 분야에서 점토광물은 점토광물 자체의 약리작용을 확인하고 원료의약품으로 활용하거나 희석제, 유화제, 점증제, 활택제 등 의약품 제형의 완성도를 높이는 첨가제로서 사용되고 있다. 벤토나이트(Bentonite), 카올린(Kaolin), 규산알루민산마그네슘(Magnesium aluminum silicate), 탤크(Talc) 등은 원료의약품 혹은 첨가제로서 활용 가능한 대표적인 점토 광물로 국내외 의약품 공정서에 수재되어 있고, 약학적 활용시 의약품등급으로 규제되고 있다. 본 논문에서는 공정서에 수재된 점토 광물을 중심으로 공정서의 규격을 확인하고, 점토광물의 특성 및 원료의약품 혹은 의약품 첨가제로서의 점토 광물에 대한 활용 사례를 소개하고자 한다. 결론적으로 점토광물을 제약산업에 활용하는 것은 점토광물의 고부가가치화를 위한 한 가지 방법이 될 수 있으며, 자원의 개발 및 활용이라는 측면에서 매우 유용할 것이라 사료된다.

Unused medication disposal is a burden due to the cost of disposing as well as the cost of the drugs. Investigating medication returns is expected to suggest areas of intervention to reduce unused medications. Purpose: The aim of this study was to examine types, quantity, costs, active pharmaceutical ingredients, and therapeutic category of the medications returned to community pharmacies. Method: From January 15, 2014 to February 28, 2014, the medications returned to the 17 community pharmacies in Gimhae, Jinju, and Incheon, Korea were examined. The pharmacists and student volunteers worked cooperatively to identify the medications and analyze drug cost of prescription pill medications returned to the pharmacies. Results: A total of 2,720 pills of prescription medication were analyzed and 91 active pharmaceutical ingredients were identified. According to the Anatomical Therapeutic Chemical (ATC) classification, the most predominant group was A (alimentary tract and metabolism) with 33.3%, followed by N (nervous system) with 15.0%. With regard to the drug cost of groups, group A was the highest with 26.6%, followed by J01 (antibacterials for systemic use) with 20.2% and N (nervous system) with 18.3%. The total cost of the oral pill prescription medications was 468,477 won. Conclusion: The result from this study implies that unused drugs impose a significant cost to the health care system in Korea. In this study, medicines used to treat gastrointestinal conditions were returned most frequently with the highest drug cost. Further research in nationwide level is necessary to establish strategies to reduce the wastage of unused medicines.

Transaminase represents the most important biocatalysts used for the synthesis of chiral amines due to their stereoselectivity. They allow asymmetric synthesis with high yields and enantioselectivity from their corresponding ketones. Due to their environmentally friendly access for the preparation of chiral amines, they have attracted growing attention in recent times. Thus, the production of chiral compounds by transaminase catalysed reactions is considered as an important application in synthetic organic chemistry. Therefore, transaminase is considered to be an important enzyme in the pharmaceutical and chemical industries. ω-Transaminase holds great potential because of its wide substrate specificity thus making it a suitable enzyme to be used at an industrial scale. This review highlights the reaction mechanism, classification, substrate specificity, and biochemical properties. The review also showcases the application of ω-transaminase in organic chemistry with a focus on the production of active pharmaceutical ingredients (APIs).

A simple and sensitive HPLC method was developed for the simultaneous determination of ten kinds of active ingredients formulated in commercial cough-cold mixtures. A group of Pseudoephedrine HCl, dl-Methylephedrine HCl, Noscapine, Chlorophenylamine maleate, Dextromethorphan HBr and Phenylpropanolamine HCl were determined at 254nm using a Novapak $C_{18}$ column with mobile phase consisting of a mixture of methanol-acetonitrile-1, 4dioxane-tetrahydrofuran-water(12 : 20 : 20 : 5 : 43, pH4.7) containing 0.013M-dioctyl sodium sulfosuccinate. The another group of Acetoaminophen, Caffeine, Guaifenesin and Ethenzamide were also determined at 254nm using a Novapak $C_{18}$ column as the stationary phase, and a mixture of methanol-1% aqueous acetic acid (3 : 7). The results indicate that these methods are accurate and precise with relative standard deviation of not more than 1% (n=5) for the above active ingredients.

Objectives: This study was conducted to clarify the effects of agarwood on histamine release from mast cells in rats and on the scratching behaviors in mice. Methods: Histamine release from rat mast cells induced by compound 48/80 or concanavalin A (Con A) and compound 48/80-induced scratching behavior in mice were examined to investigate the effects of agarwood. The hyaluronidase activity and the 3',5'-cyclic adenosine monophosphate (cAMP) levels in mast cells were examined to investigate the mechanisms for the inhibition of histamine release. The correlation between the inhibitory effects of agarwood on histamine release and the content of its typical ingredients, a 2-(2-phenylethyl)chromone derivatives, was analyzed using thin-layer chromatography. Results: Agarwood showed an inhibitory effect on mast-cell histamine release induced by compound 48/80 or Con A without any effect on hyaluronidase activity; this effect involves an increase in the cAMP levels in mast cells. Oral administration of agarwood showed an inhibitory effect on compound 48/80-induced scratching behavior in mice. The inhibitory effects of agarwood on histamine release were quite different, depending on the area where the agarwood was produced, its quality, and its market price. No correlation was found between the inhibitory effects of agarwood on histamine release and the typical ingredients of agarwood, which are 2-(2-phenylethyl)chromone derivatives. Conclusion: These results show that agarwood inhibits histamine release from mast cells partially through an increase in the cAMP levels in cells. We suggest that some active ingredients of agarwood must be effective on oral intake and that agarwood can be used to treat patients with a number of conditions, including urticaria, atopic dermatitis, and bronchial asthma, in which an increase in histamine release occurs. Differences in the pharmacological effects of this crude drug among markets may provide important information for the quality control of this herbal medicine.

Precipitation was formed during the preparation of decoction from a mixture of Scutellariae Radix and Coptidis Rhizoma or Phellodendri Cortex according to the prescription of Hwang-ryean-hae-dog-tang. Baicalin and berberine were identified in coprecipitated product and these components were the active ingredients of two herbal medicine. The coprecipitated product was very slightly soluble in water and sparingly soluble in ethanol. The stoichiometric ratio of baicalin and berberine was found to be 1:1. The lipid-water partition coefficients of coprecipitated product were increased more than baicalin and berberine in chloroform, but were decreased in other organic solvents. The content of baicalin and berberine in coprecipitated product, determined by HPLC, were 23.08% and 26.75%, but the content of active ingredients in supernatant were 0.66% and 0.26%, respectively. The dissolution profile of baicalin of coprecipitated product was increased more than extract of Scutellariae Radix in artificial gastric juice, but was decreased in artificial intestinal juice. The dissolution rate of berberine of coprecipitated product was lower than extract of Coptidis Rhizoma in artificial gastric juice and intestinal juice commonly.

Extracts of Artemisia asiatica Nakai (Asteraceae) possess anti-inflammatory and anti-oxidative activities. Eupatilin (5,7-dihydroxy-3,4,6-tri-methoxy-flavone), one of the pharmacologically active ingredients derived from Artemisia asiatica, was shown to induce apoptosis in human promyelocytic leukemia (HL-60) cells (H.-J. Seo and Y.-J. Surh, Mutat. Res., 496, 191-198, 2001). In the present study, we examined the cytostatic effects of eupatilin in H-ras-transformed human breast epithelial (MCF10A-ras) cells. (omitted)

Acanthopanacis Cortex (Acanthopanax sessiliflorum, Araliaceae, KP VIII), an important Korean medicinal herbal drug, has been widely used as tonic, anti-stress and immuno-enhancing drugs. To monitor the contents of active ingredients (acanthoside D[=eleutheroside E], eleutheroside B, isofraxidin, chlorogenic acid, and caffeic acid) in Acanthopanax sp., we developed the HPLC analysis method and validated. The simultaneous determination of five active ingredients was achieved in a C$\sub$18/ column with an acetonitrile water (containing 1 % phosphoric acid) (15 : 85) mobile phase. (omitted)
