  Synthesis of piplartine analogs and preliminary findings on structure–antimicrobial activity relationship

  摘要：

  In this work it is described the synthesis, characterization and antimicrobial and toxicity evaluation of a series of analogs of piplartine, a piperamide found in Piper sp. The compounds structures were confirmed by infrared spectroscopy, H-1, C-13 nuclear magnetic resonance, high resolution mass spectroscopy and were evaluated against strains of Candida spp., Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. Derivative 24 was almost four-fold more potent (IC50: 48.83 mu M) and five-fold less toxic (SI > 3) than piplartine (IC50: 189.2 mu M; SI: 0.21) against Candida krusei, as well as two-fold more potent than fluconazole (IC50: 104.48 mu M). This compound was also active against Candida tropicalis at 97.67 mu M. Benzoyl derivative 17 was three-fold more potent (IC50: 85.2 mu M) and more than five-fold less toxic (CC50: 231.71 mu M) than piplartine (IC50: 315.33 mu M and CC50: 41.14 mu M) against Staphylococcus aureus. Given these findings, we have found analogs of piplartine which can be assumed as prototypes for the optimization and the development of new antimicrobial (compounds 24 and 17) agents.

  article, a novel series of (E)-3-(3,4,5-trimethoxyphenyl)acrylic acid (TMCA) amide derivatives 1-18 were designed and synthesized by a facile and one-pot step, which were achieved with good yields using 1-hydroxybenzotriazole (HOBT) and 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDCI) as activation system. All the synthesized derivatives were biologically evaluated for their anticonvulsant

  本文设计了一系列新颖的（E）-3-（3,4,5-三甲氧基苯基）丙烯酸（TMCA）酰胺衍生物1-18，并通过简单的一锅法步骤合成了使用1-羟基苯并三唑（HOBT）和1-（3-二甲基氨基丙基）-3-乙基碳二亚胺盐酸盐（EDCI）作为活化体系可得到良好的收率。分别使用最大电击（MES）模型，sc-戊烯四唑（PTZ）模型，戊巴比妥钠诱发的睡眠模型和运动功能测试，对所有合成衍生物的抗惊厥，镇静活性和神经毒性进行了生物学评估。其中，化合物4、9和16在初步评估中表现出良好的抗惊厥活性。此外，化合物4是随后测试中最有效的抗惊厥药和镇静剂，而化合物4的低毒性阈值则保持警惕。在随后的测试中，化合物9和16还具有明显的抗惊厥活性，且毒性较弱。分子建模实验还预测了获得的活性分子与GABA转移蛋白的良好结合相互作用。因此，可以得出结论，合成的衍生物4、9和16将代表有用的先导化合物，用于进一步研究抗惊厥药和镇静剂。
