    • PURPOSE: Methods and compositions useful in increasing in mammals the absorption and retention of hydrophilic molecules, in particular peptides and proteins are provided. CONSTITUTION: Fatty acid derivatives of disulfide-containing compounds (for example, disulfide-containing peptides or proteins) comprising fatty acid-conjugated products with a disulfide linkage are employed for delivery of the compounds to mammalian cells. This modification markedly increases the absorption of the compounds by mammalian cells relative to the rate of absorption of the unconjugated compounds, as well as prolonging blood and tissue retention of the compounds. Moreover, the disulfide linkage in the conjugate is quite labile in vivo and thus facilitates intracellular or extracellular release of the intact compounds from the fatty acid moieties. The compound is illustrated by formula X: in which P' is a residue derived from a disulfide-containing compound which optionally may comprise a further disulfide group linked to a hydrophobic substituent of the formula VI: each R' and R4 are independently selected from the group consisting of hydrogen, lower alkyl or aryl; each R2 and R5 are independently a hydrophobic substituent; each R3 and R6 are independently selected from the group consisting of hydroxy, a hydrophobic substituent and an amino acid chain comprising one or two amino acids and terminating in -CO2H or -COR2; and n is an integer of from 1 to 20.
    • 目的:提供在哺乳动物中增加亲水性分子,特别是肽和蛋白质的吸收和保留的方法和组合物。 构成:使用包含具有二硫键的脂肪酸共轭产物的含二硫化物的化合物(例如含二硫化物的肽或蛋白质)的脂肪酸衍生物用于将化合物递送至哺乳动物细胞。 该修饰显着增加了哺乳动物细胞相对于未缀合化合物的吸收速率的吸收,以及延长了化合物的血液和组织滞留。 此外,缀合物中的二硫键在体内是非常不稳定的,因此促进完整化合物从脂肪酸部分的胞内或细胞外释放。 化合物由式X表示:其中P'是衍生自含二硫化物的化合物的残基,其任选地可以包含连接到式VI的疏水取代基的另外的二硫基:每个R'和R 4独立地选自 由氢,低级烷基或芳基组成的基团; 每个R 2和R 5独立地是疏水取代基; 每个R 3和R 6独立地选自羟基,疏水取代基和包含一个或两个氨基酸并终止于-CO 2 H或-COR 2的氨基酸链; n为1〜20的整数。

    • PURPOSE: Provided is a composition or combination of compounds that mitigate coke formation in thermal cracking furnaces. CONSTITUTION: The combination useful for reducing or preventing coke formation in thermal-cracking furnaces such as ethylene steam crackers, is comprised of one or more compound (A) of the formula R-Sx-R'(wherein R and R' are independently H, alkyl with 1 to 24 carbons straight chain or branched, aryl and x= 1 to 5); and one or more compound (B) selected from a group of formula 1(wherein R and R' are independently H, alkyl with 1 to 24 carbons straight chain or branched, aryl); and a group of formula 2(wherein R and R' are independently H, alkyl with 1 to 24 carbons straight chain or branched, aryl); and a group of formula 3(wherein R is H or alkyl, and R' and R" are alkyl of 1 to 24 carbon atoms).
    • 目的:提供减轻热裂解炉中焦炭形成的组合物或化合物的组合。 构成:用于减少或防止热裂解炉如乙烯蒸汽裂解器中的焦炭形成的组合由一种或多种式R-Sx-R'的化合物(A)组成(其中R和R'独立地为H 具有1至24个碳原子的直链或支链烷基,芳基和x = 1至5); 和一种或多种选自式1的化合物(B)(其中R和R'独立地是H,具有1至24个碳直链或支链的芳基的芳基); 和式2的基团(其中R和R'独立地为H,具有1至24个碳直链或支链的芳基的芳基); 和式3的基团(其中R是H或烷基,R'和R“是1至24个碳原子的烷基)。
