分子式:
CAS号:

性质: 肽链中的游离羟基与羧基以内酯键相连组成的抗生素统称为含内酯键的肽类抗生素。分为四个亚类:(1)放线菌素(actinomycin)类,由发色团2-氨基-4,6-二甲基吩噁嗪-3酮-1,9-二羧酸的两羧基,各引出一个含内酯环的五肽,约有百余种,由链霉菌产生,也有小单孢菌产生的。具有抗肿瘤作用,放线菌素D用于治疗何杰金氏病、神经母细胞瘤与绒毛膜上皮癌;(2)喹噁啉类,喹噁啉-2-羧酸的羧基与D-丝氨酸的氨基结合,丝氨酸的羟基与末端氨基酸的羧基形成内酯环,如左霉素(levomycin,actinoleukin,echinomycin)、醌霉素(quinomycins)、三骨霉素(triostins)等,有较强的抗革兰氏阳性菌和抗肿瘤活性,毒性大;(3)蜜柑霉素(mikamycin)-春霉素(vernamycin)类,3-羟基吡啶-2-羧酸与苏氨酸的氨基以酰胺键相连,苏氨酸的羟基与末端氨基酸的羧基形成内酯环,约有十余种,具有抗革兰氏阳性菌作用;(4)其他,如远霉素(telomycin)、蛎灰霉素(ostreogrycin)等,具有抗革兰氏阳性菌作用。
