    • Drugs, in particular, anticancer agents. More particularly speaking, anticancer agents which contain as the active ingredient(s) one or more compounds selected from among omega -hydroxyfatty acids having a specific chemical structural formula and salts and esters thereof, hydroxyoxofatty acids and salts and esters thereof, lactone compounds, macrocyclic ketones and macrocyclic diesters. The above-described compounds have a carcinostatic effect, an extremely high effect of preventing cancer metastasis, an effect of preventing recurrence of cancer, an effect of preventing the occurrence of cancer and little cytotoxicity. Moreover, these compounds are efficacious only in a small dose. Owing to these characteristics, these compounds enable the provision of anticancer agents with little side effect. The effect of preventing cancer metastasis can be further enhanced by the combined use with known anti-malignant tumor agents. Among the anticancer agents as described above, omega -hydroxyfatty acids can be very conveniently obtained at a high purity by hydrolyzing lactone compounds which are also the anticancer agents as described herein.
    • 药物,特别是抗癌剂。 更具体地说,含有作为活性成分的一种或多种选自具有特定化学结构式的ω-羟基脂肪酸及其盐和酯,羟基异烟酸及其盐和酯的化合物的抗癌剂,内酯化合物,大环 酮和大环二酯。 上述化合物具有防癌效果,预防癌症转移的极高效果,预防癌症复发的效果,防止癌症发生的效果和细胞毒性小的效果。 而且,这些化合物只能以小剂量有效。 由于这些特性,这些化合物能够提供几乎没有副作用的抗癌剂。 通过与已知的抗恶性肿瘤剂的组合使用,可以进一步提高预防癌症转移的效果。 在如上所述的抗癌剂中,通过水解也是如本文所述的抗癌剂的内酯化合物,可以非常方便地以高纯度获得ω-羟基脂肪酸。

    • A process for recovering a desired organic acid from a solution includes the steps of: providing an aqueous solution including at least one desired organic acid or its acid anion; adjusting the proton concentration in the aqueous solution to a desired level, with the desired proton concentration being selected, at least in part, by the amount of available protons needed to associate with the acid anions of the desired organic acid(s) to be recovered and/or acid anions that are weaker than the desired organic acids; and recovering at least a portion of the at least one desired organic acid from the aqueous phase. The desired proton concentration can be based on the amount of available protons being greater than, less than or substantially equal, to the amount of protons needed to associate with the anion of the desired organic acid(s) and acid anions that are weaker than the desired organic acid(s). Specific examples of suitable organic acids include, but are not limited to, ascorbic, succinic, tartaric, glyconic, gulonic, citric, lactic, malic, maleic, acetic, formic, gluconic pyruvic, propionic, butyric, itaconic acids and mixtures thereof. One embodiment of the present invention relates to the recovery of 2-keto-L-gulonic acid (KLG) from aqueous solutions such as fermentation baths.
    • 从溶液中回收所需有机酸的方法包括以下步骤:提供包含至少一种所需有机酸或其酸阴离子的水溶液; 将所述水溶液中的质子浓度调节到所需的水平,其中所需质子浓度至少部分地被选择与需要回收的所需有机酸的酸性阴离子缔合所需的可用质子的量 和/或弱于所需有机酸的酸性阴离子; 以及从所述水相中回收所述至少一种所需有机酸的至少一部分。 期望的质子浓度可以基于可用质子的量大于,小于或基本上等于与所需有机酸的阴离子和酸阴离子相比所需的质子的量,其弱于 所需的有机酸。 合适的有机酸的具体实例包括但不限于抗坏血酸,琥珀酸,酒石酸,葡萄糖酸,古洛糖酸,柠檬酸,乳酸,苹果酸,马来酸,乙酸,甲酸,葡糖酸丙酮酸,丙酸,丁酸,衣康酸及其混合物。 本发明的一个实施方案涉及从水溶液如发酵浴中回收2-酮-L-古洛糖酸(KLG)。
