  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。

  The synthesis and study of the structure–activity relationships of a series of rigid analogues of combretastatin A-4 are described which contain the 1,4-diaryl-2-azetidinone (β-lactam) ring system in place of the usual ethylene bridge present in the natural combretastatin stilbene products. The 1,4-diaryl-2-azetidinones are unsubstituted at C-3, or contain methyl substituent(s) at C-3. The most potent

  Cancer is one of the major causes of death worldwide. Although many advances have been made in the treatment and management of the disease, the existence of chemotherapy-resistance means there is still a great need to develop new strategies and drugs for its treatment. Provided herein are synthetic derivatives of combretastatin A-4, in particular those in which the aromatic rings are locked into a non-isomerisable active conformation, thus resulting in improved, stable compounds. The novel compounds are structurally related to combretastatin A-4 (CA-4) and lock the rings into the known active conformation by means of a four membered nitrogen containing heterocyclic ring, such as a beta-lactam ring, incorporated into the standard CA-4 structure. The compounds exhibit potent anti-cancer activity.

• β-Lactam analogues of combretastatin A-4 prevent metabolic inactivation by glucuronidation in chemoresistant HT-29 colon cancer cells

  Glucuronidation by uridine 5-diphosphoglucuronosyl transferase enzymes (UGTs) is a cause of intrinsic drug resistance in cancer cells. Glucuronidation of combretastatin A-4 (CA-4) was previously identified as a mechanism of resistance in hepatocellular cancer cells. Herein, we propose chemical manipulation of blactam bridged analogues of Combretastatin A-4 as a novel means of overcoming drug resistance associated with glucuronidation due to the expression of UGTs in the CA-4 resistant human colon cancer HT-29 cells. The alkene bridge of CA-4 is replaced with a b-lactam ring to circumvent potential isomerisation while the potential sites of glucuronate conjugation are deleted in the novel 3-substituted1,4- diaryl-2-azetidinone analogues of CA-4. We hypothesise that glucuronidation of CA-4 is the mechanism of drug resistance in HT-29 cells. Ring B thioether containing 2-azetidinone analogues of CA-4 such as 4-(4-(methylthio) phenyl)-3-phenyl-1-(3,4,5-trimethoxyphenyl) azetidin-2-one (27) and 3hydroxy- 4-(4-(methylthio) phenyl)-1-(3,4,5-trimethoxyphenyl) azetidin-2-one (45) were identified as the most potent inhibitors of tumour cell growth, independent of UGT status, displaying antiproliferative activity in the low nanomolar range. These compounds also disrupted the microtubular structure in MCF7 and HT-29 cells, and caused G(2)/M arrest and apoptosis. Taken together, these findings highlight the potential of chemical manipulation as a means of overcoming glucuronidation attributed drug resistance in CA-4 resistant human colon cancer HT-29 cells, allowing the development of therapeutically superior analogues.
