  摘要：

  一系列N4-芳基取代的异吲哚-3-硫半卡巴脒通过异吲哚与适当的硫脲在含有几滴醋酸的乙醇中反应制备。新合成的化合物通过其分析（CHN）和谱学（IR、1H-NMR、EIMS）数据进行表征，并评估了它们的细胞毒性和植物毒性潜力。在十三种测试的化合物中，有十一种在卤虫 lethality 生物测定中表现出显著的细胞毒活性，LD50值范围从1.75x10-5M到1.91x10-4M。在植物毒性测定中，所有合成的化合物，无论芳基取代基的性质如何，在最高测试浓度（500 μg/mL）下均表现出轻微至中等（5-30%）的植物生长抑制作用。

  Cancer multidrug resistance (MDR) mediated by ATP-binding cassette (ABC) transporters presents a significant unresolved clinical challenge. One strategy to resolve MDR is to develop compounds that selectively kill cells overexpressing the efflux transporter P-glycoprotein (MDR1, P-gp, ABCB1). We have previously reported structure-activity studies based around the lead compound NSC73306 (1, 1-isatin-4-(4'-methoxyphenyl)-3-thiosemicarbazone, 4.3-fold selective). Here we sought to extend this work on MDR1-selective analogues by establishing whether 1 showed "robust" activity against a range of cell lines expressing P-gp. We further aimed to synthesize and test analogues with varied substitution at the N4-position, and substitution around the N4-phenyl ring of isatin-beta-thiosemicarbazones (IBTs), to identify compounds with increased MDR1-selectivity. Compound 1 demonstrated MDR1-selectivity against all P-gp-expressing cell lines examined. This selectivity was reversed by inhibitors of P-gp ATPase activity. Structural variation at the 4'-phenyl position of 1 yielded compounds of greater MDR1-selectivity. Two of these analogues, 1-isatin-4-(4'-nitrophenyl)-3-thiosemicarbazone (22, 8.3-fold selective) and 1-isatin-4-(4'-tert-butyl phenyl)-3-thiosemicarbazone (32, 14.8-fold selective), were selected for further testing and were found to retain the activity profile of 1. These compounds are the most active IBTs identified to date.

  A series of N4-aryl substituted isatin-3-thiosemicarbazones was prepared by the reaction of isatin with an appropriate thiosemicarbazide in ethanol containing a few drops of acetic acid. The newly synthesized compounds were characterized by means of their analytical (CHN) and spectral (IR, 1H-NMR, EIMS) data, and evaluated for their cytotoxicity and phytotoxicity potential. Eleven out of thirteen compounds tested proved to be active in the brine-shrimp lethality bioassay exhibiting significant cytotoxic activity with LD50 values ranging from 1.75x10-5M to 1.91x10-4M. In phytotoxicity assay, all the synthesized compounds, regardless of the nature of aryl substituents, demonstrated weak to moderate (5-30%) plant growth inhibition at the highest tested concentration (500 μg/mL).
