Proteins associated to the PI3K/AKT/mTOR signaling pathway are widely used targets for cancer treatment, and in recent years they have also been evaluated as putative targets in trypanosomatids parasites, such as . Here, we performed a virtual screening approach to find candidates that can bind regions on or near the Pleckstrin homology domain of an AKT- protein in The compounds were also evaluated in vitro. The in silico and experimental results allowed us to identify a set of compounds that can potentially alter the intracellular signaling pathway through the AKT- kinase of the parasite; among them, a derivative of the pyrazolopyridine nucleus with an IC of 14.25 ± 1.00 μM against amastigotes of . In addition, we built a protein⁻protein interaction network of to understand the role of the AKT- protein in the parasite, and look for additional proteins that can be postulated as possible novel molecular targets for the rational design of compounds against .
与 PI3K/AKT/mTOR 信号通路相关的蛋白质是癌症治疗的广泛应用靶点,近年来,它们也被评估为原生动物寄生虫(如)中的潜在靶点。在这里,我们进行了虚拟筛选方法,以寻找可以与 AKT-蛋白的 Pleckstrin 同源结构域上或附近区域结合的候选物。还评估了这些化合物的体外活性。计算和实验结果使我们能够鉴定出一组化合物,它们可能通过寄生虫的 AKT-激酶改变细胞内信号通路;其中,一种具有吡唑并吡啶核的衍生物对 的无鞭毛体具有 14.25 ± 1.00 μM 的 IC。此外,我们构建了 的蛋白质⁻蛋白质相互作用网络,以了解 AKT-蛋白在寄生虫中的作用,并寻找可能被推测为针对 的合理设计化合物的潜在新分子靶标。
