  Effect of coordination to antimony(III) on the antifungal activity of 2-acetylpyridine- and 2-benzoylpyridine-derived hydrazones

  摘要：

  Antimony(III) [Sb(L)Cl-2] complexes were obtained with 2-acetylpyridine-phenylhydrazone (H2AcPh), 2-acetylpyridine-para-chloro-phenylhydrazone (H2AcpClPh), 2-acetylpyridine-para-nitro-phenylhydrazone (H2AcpNO(2)Ph) and 2-acetylpyridine-para-hydroxy-phenylhydrazone (H2AcpOHPh) along with the 2-benzoylpyridine-phenylhydrazone analogs H2BzPh, H2BzpClPh, H2BzpNO(2)Ph, H2BzpOHPh (HL). [Sb(2BzpClPh)Cl-2], complex (6), (IC50 = 4.91 +/- 1.20 mu mol L-1) was as active as nystatin (IC50= 4.44 +/- 0.76 mu mol L-1) and twofold more active than H2BzpClPh (IC50= 10.05 +/- 0.67 mu mol L-1) against Candida dubliniensis. While H2BzpClPh proved to be inactive against Candida glabrata, 6 (IC50 = 10.11 +/- 0.64 mu mol L-1) was more active than miconazole nitrate (IC50= 19.50 +/- 4.53 mu mol L-1). Similarly, H2BzpNO(2)Ph revealed to be inactive against Candida lusitaniae whereas complex [Sb(2BzpNO(2)Ph)Cl-2] (7) (IC50 = 8.54 +/- 2.21 mu mol L-1) proved to be as active as nystatin (IC50 = 5.31 +/- 0.84 mu mol L-1).

• Mild, Stereoselective, and Highly Efficient Synthesis of<i>N</i>-Acylhydrazones Mediated by CeCl₃·7H₂O in a Broad Range of Solvents

  This method uses a minimal catalytic amount of cerium(III), is stereoselective, and offers several unique features, such as compatibility with aryl, heterocyclic, alkenyl, and sensitive functional groups as well as the ability to prepare N-acylhydrazones from highly hindered substrates. More strikingly, cerium(III) efficiently mediated the reaction with less reactive substrates such as diaryl and alkyl

  在一种温和而实用的方法中，酰肼和醛在氯化铈 (III) 介导下发生缩合反应，迅速转化为 N-酰基腙。该方法使用最低催化量的铈 (III)，具有立体选择性，并提供了几个独特的功能，例如与芳基、杂环、烯基和敏感官能团的相容性以及从高度受阻的底物制备 N-酰基腙的能力. 更引人注目的是，当没有催化剂的经典方案无效时，铈 (III) 可以有效地介导与反应性较低的底物（如二芳基和烷基芳基酮）的反应。该方法能够合成结构多样的 N-酰基腙库，这些库在合成和药物化学中具有应用。

  tridentate hydrazonic ligands of the type HNNO have been used in the synthesis of some methyl palladium(II) complexes. Depending on the applied experimental conditions two different kinds of complexes are obtained. Thus, the reactions between HL1–HL5 and (COD)PdMeCl in diethyl ether led to the formation of bidentate methyl complexes of the type Pd(HNN)MeCl (1–5), where the ligands maintain a neutral character

  HNNO 类型的潜在三齿腙配体已用于合成一些甲基钯 (II) 配合物。根据所应用的实验条件，可以获得两种不同的配合物。因此，HL1-HL5 和 (COD)PdMeCl 在乙醚中的反应导致形成 Pd(HNN)MeCl (1-5) 类型的二齿甲基配合物，其中配体保持中性特征。然而，在碱如 Et3N 或 NaOMe 的存在下，配体去质子化，随后形成 Pd(NNO)Me (7-10) 类型的三齿甲基配合物。在溶液中，配合物 1-5 往往会随着甲烷的消除和三齿氯化物配合物 Pd(NNO)Cl 的形成而失去腙质子 (6)；这种趋势可能与已确定的游离配体的酸度相关。将一氧化碳通过 1-5 的溶液鼓泡，形成相应的乙酰配合物 Pd(HNN)[C(O)Me]Cl (11-15)，其中存在顺式和反式异构体。它们的摩尔比是根据基于电子考虑的分子模型研究的结果合理化的。在三齿配合物 7-10 的羰基化中发现了一种显

  A variety of N-acylhydrazones were synthesized Under microwave irradiation within 2.5-10 min, starting from benzo, salicyloyl, and isonicotinic hydrazides. The protocol developed employs microwave irradiation in the absence of solvents and catalysts, leading to high yields. The results are reproducible in a 500 mg to 5 g scale.
• Synthesis, characterization, crystal structure, and DNA binding of two copper(II)–hydrazone complexes

  Two new Cu(II)-hydrazone complexes, [Cu(L)(Hbpe)ClO4]center dot ClO4 center dot[Cu(L)Cl] (1) and [Cu (HL)(2)]center dot 1.5ClO(4)center dot 0.5OH (2) (where HL = (E)-N'-(1-(pyridine-2-yl)ethylidene)benzohydrazide and bpe = trans-1-(2-pyridyl)-2-(4-pyridyl)ethylene), have been synthesized and characterized by physicochemical methods. The structures of the complexes have been established by single-crystal X-ray diffraction direct methods, which reveal that the metal ions have distorted square-pyramidal and square-planar geometries in 1, and a distorted octahedral geometry in 2. DNA binding of HL, 1, and 2, performed by UV-vis titration in tris-buffer medium, yielded binding constants, which are 9.5 x 10(3), 1.88 x 10(4), and 4.66 x 10(4) M-1, respectively. Viscosity measurements suggest a surface or groove-binding mode of interaction between CT-DNA with HL, 1, and 2.
