A trifluoroacetamide analogue of siastatin B, (3R, 4R, 5R, 6R)-6-(trifluoroacetamido)-4, 5-dihydroxy-3-piperidinecarboxylic acid has been chemically synthesized. This compound, as well as the previously synthesized analogue, (3R, 4R, 5R, 6R)-6-(triiluoroacetamido)-3, 4, 5-trihydroxy-3-piperidinecarbo xylic acid, showed marked inhibitory activity against δ-glucuronidase and significant inhibition of experimental pulmonary metastasis of the highly metastatic melanoma B16.
一种西司他丁 B 的三氟乙酰胺类似物--(3R, 4R, 5R, 6R)-6-(triluoroacetamido)-4, 5-二羟基-3-哌啶甲酸已被化学合成。该化合物以及之前合成的类似物 (3R,4R,5R,6R)-6-(三氟乙酰氨基)-3,4,5-三羟基-3-哌啶羧酸对δ-葡萄糖醛酸酶具有明显的抑制活性,并能显著抑制高度转移性黑色素瘤 B16 的实验性肺转移。
