  扩大无毒抗疟原虫吲哚基3-乙酮醚和硫醚的SAR

  摘要：

  尽管在减少恶性疟原虫感染方面取得了长足的进步，但这种寄生虫仍然导致每年约一百万人死亡。青蒿素联合疗法的疗效下降使这一问题更加复杂。因此，开发和优化新型抗疟药化学类型至关重要。在这项研究中，我们描述了优化一类先前报告的抗疟药的战略方法，从而发现了1-（5-氯-1 H-吲哚-3-基）-2-[（4-氰基苯基）硫代]乙酮（13）和1-（5-氯-1 H-吲哚-3-基）-2-[（（4-硝基苯基）硫代]乙酮）（14），其活性与氯喹对恶性疟原虫的活性相当3D7株。此外，发现这些化合物对HeLa细胞无毒，对未感染的红血球无溶血作用。有趣的是，我们发现一些最有前途的化合物对同基因NF54菌株的活性较低，这突出表明了疟疾菌株的长期可靠性可能存在的问题。最终，化合物14对NF54和K1菌株均表现出相似的活性，表明该化合物抑制了不受K1抗性影响的途径。

  Synthesis and structure–activity relationship of new cytotoxic agents targeting human glutathione-S-transferases

  摘要：

  The 6((7-nitrobenzo[c][1,2,5]oxadiazol-4-yl)thio)hexan-1-ol (NBDHEX, 1), a "suicide inhibitor" of the glutathione-S-transferase GSTP1-1, showed pro-apoptotic properties in tumor cells, but in vivo studies were limited by poor bioavailability and high affinity towards GSTM2-2, expressed in many non-cancerous tissues. Here we describe the synthesis and biological characterization of new 1 analogs (2-40), in which the hydroxyhexyl portion at the C4-sulfur atom has been replaced with phenyl-containing moieties as well as substituted alkyl chains. Some of the new compounds displayed 10-100 times increased water-solubility (8, 11, 17, 26-28, 34, 35), and most of them showed higher GSTP1-1 selectivity (2-20, 23-26, 31-33, 35) than 1. The presence of a phenyl ring with polar substituents is in general associated, with some exceptions (23, 24) to low cytotoxicity in osteosarcoma U-2OS cells. Differently, some alkyl derivatives possess cytotoxicity comparable (26, 34,35) or higher (30, 32) than 1. Among the novel compounds, selected ones (26, 27, 34, and 35) deserve further investigation for their anticancer potential. (C) 2014 Elsevier Masson SAS. All rights reserved.

  We have studied an ester prodrug of a carbapenem to develop a potent orally active β-lactam antibiotic. A variety of 1β-methylcarbapenem derivatives have been synthesized. We have found that some derivatives having an amide group in the C-2 side chain show potent and well balanced antibacterial activities as well as high stability against dehydropeptidase-I. Oral absorption of derivatives has been optimized by modifying the C-3 ester promoiety. Pivaloyloxymethyl (1R, 5S, 6S)-6-[(R)-1-hydroxyethyl]-1-methyl-2-[(R)-5-oxopyrrolidin-3-ylthio]-1-carbapen-2-em-3-carboxylate, CS-834, has been selected as the most promising compound for further evaluation.

  In an effort to obtain a more potent and specific immunotoxin for cancer therapy, we designed a series of heterobifunctional linkers characterized by a thioimidate group linked to a S-acetyl thiol (4, 5) or substituted aryldithio group (6-10). These ligands were synthesized by a Pinner-type process from the corresponding nitrile derivatives obtained by thiol-disulphide exchange reaction, reaction with

  为了获得用于癌症治疗的更有效和更特异性的免疫毒素，我们设计了一系列异双功能接头，其特征是与S-乙酰基硫醇（4，5）或取代的芳基二硫基（6-10）连接的亚氨酸亚氨酸酯基团。这些配体通过Pinner型方法由通过硫醇-二硫化物交换反应，与取代的苯-磺酰氯的反应或其他已知方法获得的相应的腈衍生物合成。为了检查用于免疫缀合物制备的选择试剂，我们研究了中间体腈衍生物和半胱氨酸之间的巯基二硫化物交换动力学。在测试的芳基二硫代衍生物（6-10）中，我们选择了3-（4-羧酰胺基-苯基二硫代）丙硫代亚氨酸乙酯（CDPT，9）进行进一步研究。通过分析接头4、5的掺入速率。和9在模型的免疫球蛋白G蛋白中，我们发现CDPT 9和乙基S-乙酰基3-巯基丙硫代亚氨酸酯盐酸盐（AMPT，5）具有相似的结果，因为这两种试剂均显示出引入的硫醇基团数量与时间等因素之间存在线性相关性以及蛋白质和试剂的浓度。两种乙酰硫基衍生物配体4和5的比较表明，AMPT
