In our search for new safe antiparasitic agents, an enzymatic pathway was applied to synthesize a series of N-pyridinylmethyl amidesderivedfrom structurally different carboxylic acids. Thirty derivatives, including 11 newcompounds, were prepared through lipase-catalyzed acylation in excellent yields. In order to optimize the synthetic methodology, the impact of different reaction parameters was
在我们寻找新的安全抗寄生虫剂的过程中,应用酶促途径合成一系列由结构不同的羧酸衍生的N-吡啶基甲基酰胺。通过脂肪酶催化的酰化反应,以优异的收率制备了 30 种衍生物,其中包括 11 种新化合物。为了优化合成方法,分析了不同反应参数的影响。一些化合物被评估为针对克氏锥虫的抗增殖剂,克氏锥虫是导致美洲锥虫病(恰加斯病)的寄生虫。其中一些显示出作为寄生虫增殖抑制剂的显着活性。源自 2-氨基甲基吡啶、硬脂酸和反油酸的酰胺与硝呋替莫一样有效对抗克氏锥虫无鞭毛体形式(临床上相关的寄生虫形式)。更重要的是,观察到硝呋莫司和N- (吡啶-2-基甲基)硬酰胺之间存在强大的协同作用,几乎完全抑制寄生虫的增殖。此外,所获得的化合物在 Vero 细胞中没有表现出毒性,使其成为作为先导药物的极好的潜在候选者。

The development of new approaches for the treatment of antimicrobial-resistant infections is an urgent public health priority. The Pseudomonas aeruginosa pathogen, in particular, is a leading source of infection in hospital settings, with few available treatment options. In the context of an effort to develop antivirulence strategies to combat bacterial infection, we identified a series of highly effective small molecules that inhibit the production of pyocyanin, a redox-active virulence factor produced by P. aeruginosa. Interestingly, these new antagonists appear to suppress P. aeruginosa virulence factor production through a pathway that is independent of LasR and RhlR.

Disclosed are a variety of amphoteric compounds having a heterocyclic quaternary nitrogen group. The heterocycle includes pyridines, piperidines, and pyrrolidines, and is linked to a hydrophobe hydrocarbyl group via either an amide or an ester linkage. These heterocyclic amphoteric compounds can be advantageously prepared in high yield and purity by a two-step chemoenzymatic process and have excellent surfactant properties.
