  A Series of α-Heterocyclic Carboxaldehyde Thiosemicarbazones Inhibit Topoisomerase IIα Catalytic Activity

  摘要：

  A series of novel thiosemicarbazone derivatives bearing condensed heterocyclic carboxaldehyde moieties were designed and synthesized. Among them, TSC24 exhibited broad antiproliferative activity in a panel of human tumor cells and suppressed tumor growth in mice. The mechanism research revealed that TSC24 was not only an iron chelator but also a topoisomerase II alpha catalytic inhibitor. Its inhibition on topoisomerase II alpha was due to direct interaction with the ATPase domain of topoisomerase I la which led to the block of ATP hydrolysis. Molecular docking predicted that TSC24 might bind at the ATP binding site, which was confirmed by the competitive inhibition assay. These results about the mechanisms involved in the anticancer activities of thiosemicarbazones will aid in the rational design of novel topoisomerase II-targeted drugs and will provide insights into the discovery and development of novel cancer therapeutics based on the dual activity to chelate iron and to inhibit the catalytic activity of topoisomerase II alpha.

  A series of twenty one N4-aryl substituted 5-trifluoromethoxyisatin-3-thiosemicarbazones 3a-3u was synthesized by the reaction of trifluoromethoxyisatin 1 with different arylthiosemicarbazides 2 in aqueous ethanol (50%), containing a few drops of acetic acid. Their structures were established on the basis of analytical (CHN) and spectral (IR, 1H-NMR, EIMS) data. All the synthesized compounds were evaluated for their toxicity potential by a brine shrimp lethality bioassay. Ten compounds i.e., 3a, 3e, 3i-3l and 3n-3q proved to be active in this assay, displaying promising toxicity (LD50 = 1.11 × 10−5 M − 1.80 × 10−4 M). Amongst these, 3k, 3n and 3o were found to be the most active ones (LD50 = 1.11 × 10−5 M − 1.43 × 10−5 M). Compound 3k showed the highest activity with a LD50 value of 1.11 × 10−5 M and can, therefore, be used as a lead for further studies. Structure-activity relationship (SAR) studies revealed that the presence of strong inductively electron-attracting trifluoromethoxy substituent at position-5 of the isatin moiety played an important role in inducing or enhancing toxic potentiality of some of the synthesized compounds.

  通过三氟甲氧基异吲哚1与不同芳基缩氨基脲2在含有几滴醋酸的50%乙醇水溶液中的反应，合成了一系列21种N4-芳基取代的5-三氟甲氧基异吲哚-3-缩氨基脲3a-3u。它们的结构是基于分析（CHN）和光谱（IR，1H-NMR，EIMS）数据确定的。所有合成的化合物都通过卤虫致死生物测定法评估了它们的毒性潜力。其中10种化合物，即3a，3e，3i-3l和3n-3q在此测定中表现活跃，显示出有前景的毒性（LD50 = 1.11 × 10−5 M − 1.80 × 10−4 M）。在这些化合物中，3k，3n和3o被发现是最活跃的（LD50 = 1.11 × 10−5 M − 1.43 × 10−5 M）。化合物3k显示出最高的活性，其LD50值为1.11 × 10−5 M，因此可以作为进一步研究的先导化合物。构效关系（SAR）研究表明，在异吲哚部分的5位上存在强诱导电子吸引的三氟甲氧基取代基，在诱导或增强某些合成化合物的毒性潜力方面发挥了重要作用。

  A series of N (4)-aryl-substituted 5-fluoroisatin-3-thiosemicarbazones 3a-3l was synthesized and evaluated for selected biological activities. The brine shrimp lethality bioassay was carried out to study their in vitro cytotoxicity potential and besides, their antifungal, phytotoxic and urease inhibitory effects were also investigated. Seven compounds i.e. 3a, 3d, 3f, 3g, 3h, 3j and 3k proved to be active in the brine shrimp assay, displaying promising cytotoxicity (LD50 = 6.89 x 10(-5)-2.79 x 10(-4) M). Amongst these, 3a and 3h were found to be the most active ones (LD50 = 6.89 x 10(-5) and 9.79 x 10(-5) M, respectively). Compounds 3i, 3j and 3 k displayed moderate (40 %) antifungal activity against one or two fungal strains i.e. A. flavus and/or M. canis. In phytotoxicity assay, all the synthesized compounds, including the reference point 2m showed weak-to-moderate (15-70 %) activity at the highest tested concentration (500 mu g/mL). In urease inhibition assay, compounds 3f, 3g and 3j proved to be the most potent inhibitors, demonstrating relatively a higher degree of enzymatic inhibition with IC50 values ranging from 37.7 to 47.3 mu M.
