  Higher N-acyl-L-amino acid derivatives

  摘要：

  A preparative method is proposed for obtaining higher N-acylamino acids by reaction of free amino acids with fatty acid nitrophenyl esters. It was shown that these acids can transport positive ions through a liquid lipophilic medium. A direct method is proposed for obtaining fatty acid 4-nitrophenyl esters by boiling 4-nitrophenol and the fatty acid in xylene in a Soxhlet apparatus in the presence of an acid catalyst.

  新的N-酰基氨基酸和可再生脂肪酸的衍生物：烃的凝胶化和热学性质

  摘要：

  这项工作报告了从C16：0，C18：0，C18：1和C18：1（OH）脂肪酸家族合成新的脂肪N-酰基氨基酸和N-酰基氨基酯的过程，并证明了这些化合物作为有机凝胶的活性代理商。将化合物加热溶解在各种溶剂中（Ñ己烷，甲苯和汽油）。只有饱和C16：0和C18：从丙氨酸衍生0能够形成凝胶的甲苯溶液，和饱和的C16：从苯丙氨酸衍生的0表明胶凝Ñ正己烷。这是l的脂肪N-酰基氨基酯和N-酰基氨基酸衍生物的第一个证据-丝氨酸和脂肪酸C16：0，C18：0和C18：1能够与己烷形成凝胶。该观察证实了1-丝氨酸的片段衍生物中的羟基在形成良好凝胶中的重要性。

  Gelator backbone conformational flexibility plays an important role in a supramolecular self-assembly which is synergistically assisted by solvophobic interaction leading to a gelation of three sets of hydrophobically modulated dipeptidic gelators.

  1-beta-D-Arabinofuranosylcytosine (Ara-C, Cytarabine) is one of the drugs used for acute nonlympbocytic leukemia (ANLL). However, the bioavailability of Ara-C is relatively low due to its low lipophilicity. In order to improve the lipophilicity and bioavailability of Ara-C, a series of N-4 derivatives of Ara-C, i.e., (fatty acid)-(amino acid)-Ara-C analogues, were prepared. The 15 derivatives synthesized were characterized by their melting points, optical rotations and partition coefficients. It was found that the Ara-C derivatives synthesized in this study were more lipophilic than Ara-C as determined by their partition coefficients. Their in vitro cytotoxicity and in vivo anti-tumor activity were determined and compared with that of Ara-C. It was found that the derivatives were more active than Ara-C in Hela cells, but not in HL-60 cells. The in vivo results showed that some of the derivatives were more effective than Ara-C in mice bearing S-180 tumor while others showed a decreased activity in comparison with Ara-C.
