    • The present invention relates to a microemulsion preconcentrate composition comprising (1) cyclosporin as an active component; (2) alkyl ester of polycarboxylic acid and/or carboxylic acid ester of polyols as a lipophilic solvent; (3) oil; and (4) surfactant. The composition according to the present invention is characterized in that it dissolves in an external phase such as water, artificial gastric fluid and artificial intestinal fluid by controlling the mixing ratio of the components thereby to get the microemulsion form of inner phase diameter of 100 nm or below. The composition according to the present invention can be formulated as the dosage form of a soft capsule, a hard capsule sealed with a gelatin banding at the conjugated portion, or an oral liquid preparation for oral administration. Especially, if the cyclosporin microemulsion preconcentrate comprising cyclosporin, oil, lipophilic solvent and surfactant is formulated in a soft capsule according to the present invention, the resultant capsule removes the disadvantages of the prior arts showing the reactivity of hydrophilic solvent with gelatin shell of soft capsule and the volatility of hydrophilic solvent wherein the hydrophilic solvent was essential component in the composition according to the existing patents.
    • 本发明涉及一种微乳液预浓缩组合物,其包含(1)环孢菌素作为活性成分; (2)多元羧酸的烷基酯和/或作为亲脂性溶剂的多元醇的羧酸酯; (3)油; 和(4)表面活性剂。 根据本发明的组合物的特征在于通过控制组分的混合比例在水相,人造胃液和人造肠液等外界溶解,得到内相直径为100nm的微乳液形式,或 下面。 根据本发明的组合物可以配制成软胶囊的剂型,用共轭部分的明胶带密封的硬胶囊,或用于口服给药的口服液制剂。 特别地,如果将包含环孢菌素,油,亲脂性溶剂和表面活性剂的环孢菌素微乳液预浓缩物配制在根据本发明的软胶囊中,则所得胶囊消除了现有技术的缺点,显示亲水性溶剂与软胶囊明胶壳的反应性 和亲水性溶剂的挥发性,其中亲水性溶剂是根据现有专利的组合物中必需组分。

    • The present invention relates to an improved process for preparing simvastatin and more particularly, the improved process for preparing simvastatin expressed by formula 1 with high yield and high purity by performing the following sequential processes comprising: (i) hydrolysis of lovastatin as starting material with potassium t-butoxide in an organic solvent and small amount of water under a mild reaction condition, followed by lactonization of the obtained solid intermediate with preventing from formation of by-products; (ii) protection of an alcohol group with t-butyldimethylsilyl group which can be easily removed with concentrated hydrochloric acid without the formation of by-products; (iii) acylation of the obtained protected intermediate with acyloxytriphenyl phosphonium salt as an acylating agent under a mild reaction condition; and (iv) removal of the silyl protective group with a concentrated hydrochloric acid. The present invention is to provide the improved process of preparing simvastatin expressed by formula 1 environmentally sound, economically efficient, and industrially useful.
    • 本发明涉及一种制备辛伐他汀的改进方法,更具体地说,涉及通过进行以下顺序方法制备具有高产率和高纯度的式1所表达的辛伐他汀的改进方法,包括:(i)将洛伐他汀作为原料与钾 叔丁醇在有机溶剂和少量水中,在温和的反应条件下,然后将所得固体中间体内酯化,防止副产物的形成; (ii)用叔丁基二甲基甲硅烷基保护醇基,其可以用浓盐酸容易地除去而不形成副产物; (iii)在温和的反应条件下用酰氧基三苯基鏻盐作为酰化剂酰化所得保护的中间体; 和(iv)用浓盐酸除去甲硅烷基保护基。 本发明提供了由式1表达的辛伐他汀的改进方法,其在环境无害,经济有效和工业上有用。
