Hit finding in early drug discovery is often based on high throughput screening (HTS) of existing and historical compound libraries, which can limit chemical diversity, is time-consuming, very costly, and environmentally not sustainable. On-the-fly compound synthesis and in situ screening in a highly miniaturized and automated format has the potential to greatly reduce the medicinal chemistry environmental
feasibility of the synthesis of a large library based on 16 different chemistries in parallel on several 384-well plates using the acoustic dispensing ejection (ADE) technology platform. In contrast to combinatorialchemistry, we produced 16 scaffolds at the same time and in a sparse matrix fashion, and each compound was produced by a random combination of diverse large building blocks. The synthesis, analytics
miniaturized and accelerated synthesis for efficient property optimization is a formidable challenge for chemistry in the 21st century as it helps to reduce resources and waste and can deliver products in shorter time frames. Here, we used for the first-time acoustic droplet ejection (ADE) technology and fast quality control to screen efficiency of synthetic reactions on a nanomole scale in an automated
实现高效性能优化的自动化、小型化和加速合成是 21 世纪化学面临的巨大挑战,因为它有助于减少资源和浪费,并可以在更短的时间内交付产品。在这里,我们首次使用声学液滴喷射(ADE)技术和快速质量控制,以自动化和小型化的方式筛选纳摩尔级合成反应的效率。中断的费歇尔吲哚与 Ugi 型反应相结合,产生了几种有吸引力的药物样支架。在 384 孔板中,产生了一组不同的间断 Fischer 吲哚中间体,并通过两步序列与三环乙内酰脲骨架反应。同样,预制的 Fischer 吲哚中间体用于生产多种 Ugi 产品,并将效率与原位方法进行了比较。在制备毫摩尔规模上重新合成了多个反应,显示出从纳米到毫克的可扩展性,从而显示出合成实用性。前所未有的大量建筑被用于快速范围和限制研究(68 种异氰化物,72 种羧酸)。生成的大合成数据的小型化和分析使得能够更深入地探索化学空间,并获得以前不切实际或不可能的知识,例如反应、结构单元和官能团兼容性的快速调查。
