  Efficient Syntheses of Pyrofolic Acid and Pteroyl Azide, Reagents for the Production of Carboxyl-Differentiated Derivatives of Folic Acid

  摘要：

  Reaction of folic acid (1) with excess trifluoroacetic anhydride provides access to both the previously unknown N-10-(trifluoroacetyl)pyrofolic acid (8) and pyrofolic acid (9). Reaction of either of these materials with hydrazine selectively affords pteroyl hydrazide (13), which may be oxidized to pteroyl azide (27) on a large scale (62% overall from 1 without the need for chromatography). Treatment of 27 with differentially protected glutamates provides a convenient and high-yielding synthesis of differentially protected, optically pure folates.

• Folate-modified cholesterol-bearing pullulan as a drug carrier
  申请人：Sunamoto Junzo

  Folate modified cholesterol-bearing pullulan (FA-CHP) was synthesized by the reaction of folic acid γ-2-aminoethylamide and 4-nitorophenyl chloroformate-activated cholesterol-bearing pullulan, wherein folate and pullulan are connected through a NH—CH 2 —CH 2 —NH group. Approximately 0.5-1 folates are connected per about 100 glycoside units of pullulan. Then, several combinations of FA-CHP, cholesterol-bearing pullulan (CHP) and doxorubicin (DOX) mixture were tested for cancer selective cytotoxicity. A mixture of FA-CHP, CHP and DOX of 1:4:0.02 (weight ratio) gave sharp and selective damage to cells of a human epidermoid cancer KB known as expressing a high level of folate receptor. The same mixture inhibited the growth of HuH7 cells, which is a human hepatocellular carcinoma and is unknown as a folate receptor.

  叶酸修饰的胆固醇载体泊洛聚糖（FA-CHP）是通过叶酸γ-2-氨基乙酰胺和4-硝基苯基氯甲酸酯活化的胆固醇载体泊洛聚糖反应合成的，其中叶酸和泊洛聚糖通过一个NH—CH2—CH2—NH基团连接。每约100个葡糖苷单元中连接了大约0.5-1个叶酸。然后，对叶酸修饰的胆固醇载体泊洛聚糖（FA-CHP）、胆固醇载体泊洛聚糖（CHP）和阿霉素（DOX）混合物进行了多种组合的癌症选择性细胞毒性测试。FA-CHP、CHP和DOX的混合物比例为1:4:0.02（重量比）对人表皮癌KB细胞具有高叶酸受体表达水平的细胞造成了明显和选择性的损伤。同样的混合物抑制了HuH7细胞的生长，这是一种人类肝细胞癌，并且未知是否具有叶酸受体。
