    • A process for extracting oleanolic acid from plant material is disclosed. Dried plant material is provided and an extraction process is carried out with a non-halogenated polar to medium polar solvent. The resulting solution that contains oleanolic acid is separated from the plant material and the solvent is removed using cooling, vacuum-evaporation or other techniques. A precipitate is formed that contains mostly oleanolic acid. Subsequent purification steps to provide highly purified oleanolic acid include washing techniques, re-crystallization techniques or the use of chromatography.
    • 公开了从植物材料中提取齐墩果酸的方法。 提供干燥植物材料,并用非卤化的极性至中等极性溶剂进行萃取过程。 将所得到的含有齐墩果酸的溶液与植物材料分离,并使用冷却,真空蒸发或其它技术除去溶剂。 形成大部分含有齐墩果酸的沉淀物。 提供高度纯化的齐墩果酸的后续纯化步骤包括洗涤技术,重结晶技术或色谱法的使用。

    • Enamide derivatives of formula (1) are described: wherein R1 is a group Ar1L2Ar2Alk- in which Ar1 is an optionally substituted aromatic or heteroaromatic group, L2 is a covalent bond or a linker atom or group, Ar2 is an optionally substituted arylene or heteroarylene group and Alk is a chain —CH2—CH(R)—, —CH═C(R)— or  in which R is a carboxylic acid (—CO2H) or a derivative or biostere thereof; R2 is a hydrogen atom or a C1-6alkyl group; X is an O or S atom or the group NR30 group; j and k is each zero or the integer 1 or 2 provided that the sum of j and k is zero or the integer 1 or 2; Cy1 is an optionally substituted cycloaliphatic, heterocycloaliphatic, aromatic or heteroaromatic group; and the salts, solvates, hydrates and N-oxides thereof. The componds are able to inhibit the binding of integrins to their ligands and are of use in the prophylaxis and treatment of immune or inflammatory disorders, or disorders including the inappropriate growth or migration of cells.
