  设计，合成了一系列3-脱甲氧基羰基-3-酰胺甲基脱水长春碱衍生物（5b - 24b），并评估了它们对两种肿瘤细胞系（A549和HeLa）的增殖抑制活性。大多数酰胺脱水长春碱衍生物表现出强的细胞毒性，所引入的取代基的大小是确定所得细胞毒性活性的最主要因素。针对三种有效化合物（6b，12b和24b）对肉瘤180的体内测试结果表明，在脱水长春碱（1e）的22位引入酰胺基可以提高效力和毒性。

  Synthetically-derived and previously inaccessible modifications of 20'-hydroxy-vinca derivative compounds such as vinblastine, vincristine or vindesine are disclosed that are a stunning 100-fold more active than the natural product (IC50's 50-75 pM vs 7 nM, HCT116), and are now accessible as a result of advances in the total synthesis of the natural product. Illustrative new ultra-potent vinblastines bind tubulin with much higher affinity and likely further disrupt the tubulin head-to-tail α/β dimer-dimer interaction by virtue of the strategic placement of an added conformationally well-defined, rigid and extended C20'-urea along the adjacent protein-protein interface. Added molecular complexity was used to markedly enhance target binding and functional biological activity, and represents a general approach to improving the properties of other natural products targeting a protein-protein interaction. A pharmaceutical composition containing an ultra-potent 20'-hydroxy-vinca derivative compound and a method of treating cancerous cells with such a compound are also disclosed.

  Sixty-two congeners of vinblastine (VLB), primarily with modifications of the piperidine ring in the carbomethoxycleavamine moiety of the binary alkaloid, were synthesized and evaluated for cytotoxicity against murine L1210 leukemia and RCC-2 rat colon cancer cells, and for their ability to inhibit polymerization of microtubular protein at <10−6 M, and for induction of spiralization of microtubular protein, and for microtubular disassembly at 10−4 M concentrations. An ID50 range of >107 M concentrations was found for L1210 inhibition by these compounds, with the most active 1000× as potent as vinblastine.

  合成了长春碱（VLB）的62个类似物，主要是通过改变二元生物碱中碳甲氧基克拉维胺部分的哌啶环来修改结构，并评估了它们对小鼠L1210白血病和大鼠RCC-2结肠癌细胞的细胞毒性，以及它们在<10^-6 M浓度下抑制微管蛋白聚合、诱导微管蛋白螺旋化和在10^-4 M浓度下解聚微管的能力。这些化合物对L1210的抑制作用表现出>10^7 M的ID50范围，其中最活跃的化合物比长春碱的效力高出1000倍。
