In order to investigate the structure-activity relationships, fourteen derivatives of myriocin ((2S', 3R, 4R)-(E)-2-amino-3, 4-dihydroxy-2-hydroxymethyl-14-oxoeicos-6-enoic acid) were prepared and examined for immunosuppressive activity on mouse allogeneic mixed lymphocyte reaction in vitro. Among them, 14-deoxomyriocin ((2S, 3R, 4R)-(E)-2-amino-3, 4-dihydroxy-2-hydroxymethyl-eicos-6-enoic acid) was the most potent. It also suppressed the generation of allo-reactive cytotoxic T lymphocytes in mice upon intraperitoneal administration, with a potency 10-fold greater than that of myriocin.
为了研究结构与活性之间的关系,我们制备了14种米利霉素((2S', 3R, 4R)-(E)-2-amino-3, 4-dihydroxy-2-hydroxymethyl-14-oxoeicos-6-enoic acid)衍生物,并检测其对小鼠异体混合淋巴细胞反应的免疫抑制活性。其中,14-脱氧米利霉素((2S, 3R, 4R)-(E)-2-amino-3, 4-dihydroxy-2-hydroxymethyl-eicos-6-enoic acid)是最有效的。它还能抑制小鼠腹腔注射后产生的异体反应性细胞毒性T淋巴细胞,效力是米利霉素的10倍。
