  Total Synthesis of Islandic Acid I Methyl Ester, Rosellisin and Rosellisin Aldehyde

  摘要：

  Total synthesis of islandic acid I methyl ester (2), rosellisin (3) and rosellisin aldehyde (4) has been accomplished starting from 4-hydroxy-5-hydroxymethyl-6-methyl-2H-pyran-2-one (9a) via formylation of 9a with dichloromethyl methyl ether and titanium tetrachloride as a key step.

  The effects of islandic acid-I (1) and related compounds on the growth of Yosida sarcoma cells and on the transfection of Bacillus phage M2-DNA have been investigated. Compound 1 inhibited the growth of Yoshida sarcoma cells at 100μg/ml, while its methyl ester (2) was 100 times more potent. Islandic acid-II methyl ester (4) and 2 produced 83 and 97% inhibition of the transfection of Bacillus phage M2-DNA at 33 and 66μg/ml, respectively. Methyl (2Z, 4E)-hexadienoate (5), having the same configuration as the side chain of 1, also inhibited the transfection of M2-DNA over a wide concentration range, but did not show cytotoxicity against Yoshida sarcoma cells in tissue culture even at 100μg/ml.

  已对岛状酸-I（1）和相关化合物对Yosida肉瘤细胞生长和Bacillus phage M2-DNA转染的影响进行了研究。化合物1在100μg/ml浓度下抑制了Yoshida肉瘤细胞的生长，而其甲基酯（2）的效力则高出100倍。岛状酸-II甲基酯（4）和2在33和66μg/ml浓度下分别对Bacillus phage M2-DNA转染产生83%和97%的抑制作用。甲基（2Z，4E）-己二烯酸酯（5）与1的侧链具有相同的结构，在较宽的浓度范围内也抑制了M2-DNA的转染，但在组织培养中即使浓度达到100μg/ml，也未显示对Yoshida肉瘤细胞的细胞毒性。
