  摘要：

  Dicationic 2,5-bis(4-guanidinophenyl)furans 5a-5f, 2,5-bis [4-(arylimino)aminophenyl] furans 6a -6b and 6e-6k, and 2,5-bis [4-(alkylimino)aminophenyl] furans 6c -6d have been synthesized starting from 2,5-bis [tri-n-butylstannyl] furan. Thermal melting studies with poly dA . dT and the duplex oligomer d(CGCGAATTCGCG)2 demonstrated high DNA binding affinities for a number of the compounds. The binding affinities are highly dependent on structure and are significantly affected by substituents both on the phenyl rings of the 2,5-diphenylfuran nucleus and on the cationic centers. Of the 17 novel dicationic compounds synthesized, six (6a, 6b, 5b, 6f, 6fi, 6i) exhibited MICs of 2 mug/mL or less versus Mycobacterium tuberculosis. Of the compounds screened against Candida albicans, three gave MICs of 2 mug/mL or less (5b, 6h, Si), and two (5b, 6i) were fungicidal, unlike a standard antifungal drug fluconazole, which was fungistatic. In addition, one of the tested compounds (6i) exhibited a MIC of <1 mug/mL against Aspergillus fumigatus, while also being a fungicidal against this organism. Finally, when evaluated against an expanded fungal panel, compound 6h showed good activity against Cryptococcus neoformans and Rhizopus arrhizus.

  六氟异丙醇作为溶剂和促进剂在Paal-Knorr合成N-取代的二芳基吡咯中

  摘要：

  据报道，通过Paal-Knorr吡咯合成方法，由通常难溶的相应1,4-二酮可无添​​加剂合成具有挑战性的N-取代的芳基吡咯，该方法利用了1,1,1,3的独特性质，3,3-六氟异丙醇（HFIP）作为溶剂和反应促进剂。我们的程序提供了简单的执行和纯化方法，以及易于放大的规模，可用于Paal-Knorr合成中，结构复杂的许多吡咯，包括中等难度到极高产率的具有挑战性的四和五取代的吡咯。HFIP也可以用作呋喃和噻吩的Paal-Knorr合成中的溶剂。然而，在吡咯的合成中，溶剂作用更为明显。

  exhibited the highest activity with submicromolar IC50 values, ranging from 0.29 to 0.36 μm, which is comparable in efficacy to the reference drug amphotericin B (IC50 0.28 - 0.33 μm). The results justify further study of this class of compounds. It seems that the combination of catechol chelating groups with potent antiparasitic agents could improve the efficacy by presenting novel hybrid compounds.

  The ionic liquid 1-butyl-3-methyl-imidazolium hydrogen sulfate, [bmim]HSO4, efficiently catalyzes Paal–Knorr furan synthesis without any organic solvent. A wide range of aliphatic and aromatic 1,4-diketones easily undergo condensations to form furan derivatives, providing a general and convenient procedure. The Paal–Knorr reaction of ester-substituted 1,4-diketones is first reported. The ionic liquid

  transform aryl diazonium salts into aryl radicals. Experimental and computational studies show that Hantzsch esters transfer hydride to aryl diazonium species, and that oxygen initiates radical fragmentation of the diazene intermediate to produce aryl radicals. The operational simplicity of this addition-fragmentation process for the generation of aryl radicals, by a polar-radical crossover mechanism, has been

• Novel Furanylarylene Arylsulfonylindolesulfonamides: Synthesis and Their Antibacterial Evaluation
  作者：Chennan Ramalingan、In-Sook Lee、Young-Woo Kwak

  DOI：10.1248/cpb.57.591

  日期：——

  An array of furanylarylene arylsulfonylindolesulfonamides was synthesized through multi-step synthetic protocols involving bromination, stannylation, Stille cross coupling, reduction, arylsulfonylation, chlorosulfonylation, and condensation reactions. As a preliminary evaluation, these analogs were tested for antibacterial activity against a series of bacterial strains such as Bacillus subtilis, Enterococcus faecalis, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Klebsiella pneumoniae using a two-fold serial dilution assay. Whereas analogs possessing unsubstitution, bromosubstitution, or methyl substitution on the benzene ring of benzenesulfonyl group were less active/inactive, the methoxy and chloro substituted counterparts were demonstrated to be comparatively more active. A few of them were found to exhibit better activity than the standard, streptomycin against selective organisms.

  通过涉及溴化、链烷化、Stille 交叉偶联、还原、芳基磺酰化、氯磺酰化和缩合反应的多步合成方案，合成了一系列呋喃芳基芳基磺酰基吲哚磺酰胺。作为初步评估，我们采用两倍序列稀释法测试了这些类似物对一系列细菌菌株（如枯草杆菌、粪肠球菌、金黄色葡萄球菌、铜绿假单胞菌、大肠埃希菌和肺炎克雷伯菌）的抗菌活性。苯磺酰基苯环上未取代、溴取代或甲基取代的类似物活性较低，甲氧基和氯取代的类似物活性相对较高。研究发现，与标准链霉素相比，其中一些药物对选择性生物的活性更好。
