    摘要:
    合成了一系列二十个2,6-二芳基哌啶-4-一O-甲基肟,在C-2和C-6的苯基的各个位置上都有氟/氯/溴/甲基/甲氧基/乙氧基/异丙基取代基,与/在仲氨基上没有甲基取代基,在活性亚甲基中心上没有甲基/乙基/异丙基取代基。不论它们的取代方式是什么,所有化合物都主要存在于椅子构象中,除了3m,它采用的是扭曲船构型。评价所有合成的化合物对人宫颈癌(HeLa)细胞系的体外抗增殖活性。通过用MTT测定法测量处理24小时后的活细胞数来确定测试化合物的细胞毒性。初步的SAR结果表明,一些铅分子3c-f,3j-k,4d-g和4i具有对哌啶酮药效团进一步结构优化的范围,以促进抗癌药物合成的发展。

    NMR spectral study of some 2r,6c-diarylpiperidin-4-one (3′-hydroxy-2′-naphthoyl)hydrazones with special reference to γ-syn effect
    摘要:
    H-1 and C-13 NMR spectra have been recorded for 2r,6c-diarylpiperidin-4-one (3'-hydroxy-2'-naphthoyl)hydrazones 10-17 and 3,3-dimethyl-2r,6c-bis(p-methoxyphenyl)piperidin-4-one (5). For selected compounds 20 NMR spectra have been recorded. The spectral data along with those reported for related compounds are used to study the effect of a heteroatom X on the C-13 chemical shift of a gamma-carbon with X C-alpha C-beta C-gamma torsional angle close to 0 degrees, termed as gamma-syn effect. Also gamma-gauche and delta-effects of the alkyl groups at C-3 on the carbons of the aryl group at C-2 have been studied. The chemical shifts for the naphthalene ring are in accord with the mesomeric and steric effects of the carbonyl and hydroxy groups. (C) 2010 Elsevier B.V. All rights reserved.

    Fifteen novel biologically active piperidin-4-one oxime esters (8-22) have been synthesized with good yields. These compounds were prepared from in-situ activated carboxylic acids using POCl3 and pyridine with piperidin-4- one oximes. The structure of the title compounds were elucidated on the basis of FT-IR, NMR (1D and 2D) and mass spectral analyses. The single crystal XRD study of compounds 12 and 20 were the further evidence for the proposed structure unambiguously. All the synthesized compounds were tested for in vitro antibacterial and antifungal activities. Many of these derivatives exhibited good activity against Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli, Trigoderma veride and Aspergillus flavus.
