The preparation method comprises monomer synthesis and polymer synthesis. The polymer synthesis is that cyclopentadienyl sodium monomer is added into metallic cobalt complex-triphenyl phosphorus cobalt chloride under strict oxygen-free and water-free conditions, and then double inner alkyne or outer alkyne conjugate monomer is added in, and after reaction, the precipitation, filtering, abstersion and vacuum-drying are carried out, the large molecules polymer containing cyclopentadienyl cobaltocenium organometallic cobalt is obtained.
制备方法,包括单体合成和聚合物的合成,聚合物的合成是在严格无氧无水条件下,在金属钴配合物三-三苯基磷氯化钴,加入环戊二烯钠单体,随后加入双内炔或双外炔共轭单体,反应后沉淀,过滤,洗涤,真空干燥,得到含环戊二烯茂钴有机金属钴的大分子聚合物。

The observation that 2-Alkylidene or Benzylidene cyclopentanones had little anticancer activity and 2-dimethylaminomethylcyclopentanone hydro- chloride (T59) had low anticancer activity proved that the existance of α,β-unsaturated carbonyl group could enhance the anticancer activity of cyclopentanone Mannich bases.
2-亚烷基、苯亚甲基环戊酮无抗癌活性,2-二甲胺甲基环戊酮盐酸盐(T59)抗癌活性较低,这些事实说明Ⅰ类化合物中的环外不饱和双键是一个增效基团,它的存在能明显增强环戊酮Mannich碱的抗癌活性。

METHODS: Collaborative meta-analyses were undertaken of 194 unconfounded randomised trials of adjuvant chemotherapy or hormonal therapy that began by 1995. Many trials involved CMF (cyclophosphamide, methotrexate, fluorouracil), anthracycline-based combinations such as FAC (fluorouracil, doxorubicin, cyclophosphamide) or FEC (fluorouracil, epirubicin, cyclophosphamide), tamoxifen, or ovarian suppression: none involved taxanes, trastuzumab, raloxifene, or modern aromatase inhibitors.
对194个开始于1995年的关于辅助化疗或激素治疗的随机试验进行meta分析,许多试验包含了CMF(环磷酰胺、氨甲喋呤、氟尿嘧啶),蒽环药物为基础的联合化疗比如FAC(氟尿嘧啶、阿霉素、环磷酰胺)或FEC(氟尿嘧啶、表阿霉素、环磷酰胺)及他莫昔芬或卵巢去势;无一包含紫杉烷类、赫赛汀、雷洛昔芬及芳香化酶抑制剂。
