  摘要：

  A series of Mannich bases of 2-alkyl-3-hydroxy-pyridine-4-ones, namely 2-alkyl-3-hydroxy-5-N-piperidylmethyl or N,N-dialkylaminomethyl pyridine-4-ones 9, 10 and 15-18, two derivatives of N-aryl-2methyl-3-hydroxy-pyridine-4-ones 19, 20 and two N-alkyl derivatives of maltol, 21 and 22 were prepared. They were screened for their antibacterial and antifungal activities against a variety of microorganisms using micro plate Alamar Blues assay (MABA) method. Multiple linear regressions (MLR) analysis was performed for the synthesized compounds as well as a series of pyridinone and pyranone derivatives 23-43 which have been synthesized and evaluated for antimicrobial activity by other researchers previously. Studied compounds showed a better quantitative structure-activity relationship (QSAR) model for the antimicrobial activity against Candida albicans and Staphylococcus aureus in comparison with other tested microorganisms.

  设计和合成用于光动力疗法的5-氨基松油酸/ 3-羟基吡啶酮共轭物：增加原卟啉IX的产生和肿瘤细胞的光毒性† ‡

  摘要：

  5-氨基戊酸（ALA）及其衍生物已在光动力疗法（PDT）中广泛用作光敏剂，原卟啉IX（PpIX）的皮肤病学和泌尿科疾病的前体。然而，由于ALA的低生物利用度限制了ALA-PDT，这是由于ALA由于其在生理pH下的两性离子性质而难以被细胞吸收。为了提高治疗效果并诱导更高水平的PpIX，通过ALA与氨基酸结合的ALA与3-羟基吡啶-4-酮（HPO）铁螯合剂的结合，合成了一系列ALA前药。酰胺键。药代动力学研究表明，与单独使用ALA或同时使用ALA和CP94（1,2-二乙基-3-羟基吡啶-4-酮）相比，一种ALA-HPO共轭物可显着增强一系列肿瘤细胞系中PpIX的产生。细胞内的卟啉荧光水平与光照射后的细胞光毒性显示出良好的相关性，表明ALA-HPO偶联物在光动力疗法中的潜在应用。

  A range of hexadentate 3‐hydroxypyridin‐4‐ones (HPOs) with high affinity for iron(III) has been synthesized. The log stability constants of two HPO–iron complexes (logK1) were determined to be over 34, and pFe values of the two HPOs were determined to be over 31. Antimicrobial assay indicated that they are able to markedly inhibit the growth of both Gram‐positive and Gram‐negative bacteria. Compounds 14a and 14e were found to exhibit the strongest inhibitory activity against Staphyloccocus aureus, Bacillus subtilis, Pseudomonas aeruginosa, and Escherichia coli, with MIC values of 8, 8, 16, and 8 μg/mL, respectively. These results indicate that hexadentate 3‐hydroxypyridin‐4‐ones have potential application as antimicrobial agents, especially in the treatment of wound infection.
• Design, synthesis and biological evaluation of 5-aminolaevulinic acid/3-hydroxypyridinone conjugates as potential photodynamic therapeutical agents

  5-Aminolaevulinic acid (ALA) prodrugs have been widely used in photodynamic therapy (PDT) as precursors to the natural photosensitizer, protoporphyrin IX (PpIX). The main disadvantage of this therapy is that ALA is poorly absorbed by cells due to its high hydrophilicity. In order to improve the therapeutical effect and induce higher yields of PpIX, a range of prodrugs of ALA conjugated to 3-hydroxypyridin4-ones (HPO) were synthesized. Pharmacokinetic studies indicated that some of the ALA-HPO conjugates are more efficient than ALA for PpIX production in the human breast adenocarcinoma cell line (MDA-MB-468). The intracellular porphyrin fluorescence levels showed good correlation with cellular phototoxicity following light exposure, suggesting the potential application of the ALA-HPO conjugates in photodynamic therapy.
