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。
