  摘要：

  微管靶向药物是各种癌症的重要化疗药物。一系列3-乙烯基-β-内酰胺（2-氮杂环丙酮）被设计、合成并评估为潜在的微管聚合抑制剂，以及它们在乳腺癌细胞中的抗增殖效应。这些化合物在MCF-7乳腺癌细胞中表现出强大的活性，其中化合物7s（4-[3-羟基-4-甲氧基苯基]-1-(3,4,5-三甲氧基苯基)-3-乙烯基氮杂环丙酮）的IC50值为8 nM，与康布雷他定A-4的活性相当。化合物7s对非肿瘤性HEK-293T细胞和小鼠乳腺上皮细胞均具有最小的细胞毒性。这些化合物在体外抑制了微管的聚合，在10 μM的浓度下，化合物7s使微管聚合减少了8.7倍，并且显示出它们与微管上的秋水仙碱结合位点相互作用，导致显著的G2/M期细胞周期阻滞。MCF-7细胞的免疫荧光染色证实了β-内酰胺7s靶向微管，并导致有丝分裂灾难。对于3-乙烯基-β-内酰胺7s在微管秋水仙碱结合区域的潜在结合构象进行的对接模拟表明了潜在的结合构象。这些化合物是作为抗增殖微管破坏剂的发展有前途的候选药物。

We report the synthesis and biological properties of a series of novel 3-chloro-β-lactams and 3,3-dichloro-β-lactams (2-azetidinones) that are structurally related to the tubulin polymerisation inhibitor and vascular targeting agent, Combretastatin A-4.

  A visible-light-driven enantioselective radical addition to imines enabled by the direct excitation of a chiral phosphoric acid–imine complex was developed. By using benzothiazolines as the radical precursors, chiral amine products were obtained with high enantioselectivities (up to 98% ee). Mechanistic studies elucidated that the chiral phosphoric acid–imine complex has photoredox activities for oxidizing

  Structure-activity relationships for a series of 3-phenoxy-1,4-diarylazetidin-2-ones were investigated, leading to the discovery of a number of potent antiproliferative compounds, including trans-4-(3-hydroxy-4-methoxyphenyl)-3-phenoxy-1-(3,4,5-trimethoxyphenyl)azetidin-2-one (78b) and trans-4-(3-amino-4-methoxyphenyl)-3-phenoxy-1-(3,4,5-trimethoxyphenyl)azetidin-2-one (90b). X-ray crystallography studies indicate the potential importance of the torsional angle between the 1-phenyl A ring and 4-phenyl B ring for potent antiproliferative activity and that a trans configuration between the 3-phenoxy and 4-phenyl rings is generally optimal. These compounds displayed IC50 values of 38 and 19 nM, respectively, in MCF-7 breast cancer cells, inhibited the polymerization of isolated tubulin in vitro, disrupted the microtubular structure in MCF-7 cells as visualized by confocal microscopy, and caused G(2)/M arrest and apoptosis. Compound 90b possessed a mean GI50 value of 22 nM in the NCI60 cell line screen, displayed minimal cytotoxicity, and was shown to interact at the colchicine-binding site on beta-tubulin. Phosphate and amino acid prodrugs of both 78b and 90b were synthesized, of which the alanine amide 102b retained potency and is a promising candidate for further clinical development.

  The structure-activity relationships of antiproliferative beta-lactams, focusing on modifications at the 4-position of the beta-lactam ring, is described. Synthesis of this series of compounds was achieved utilizing the Staudinger and Reformatsky reactions. The antiproliferative activity was assessed in MCF-7 cells, where the 4-(4-ethoxy)phenyl substituted compound 26 displayed the most potent activity with an IC(50) value of 0.22 mu M. The mechanism of action was demonstrated to be by inhibition of tubulin polymerisation. Cell exposure to combretastatin A-4 and 26 led to arrest of MCF-7 cells in the G2/M phase of the cell cycle and induction of apoptosis. Additionally, mitotic catastrophe for combretastatin A-4 and for 26 was demonstrated in breast cancer cells for the first time, as evidenced by the formation of giant, multinucleated cells.
