An in-house developed automated synthesis suite was used to prepare a library of 72 tetrapeptide derivatives, the starting materials for pharmaceutically attractive pentapeptides, employing a convergent strategy. An initial set of 18 dipeptides were synthesized on a large-scale (100-1000 g) using automated synthesis workstations, and then 72 tetrapeptides were synthesized on a medium scale (5-10 g) using an automated system. Each di- or tetrapeptide was prepared in a single operating cycle using a modified methanesulfonic acid method, then a sub-library of 56 pentapeptides were synthesized in parallel, on a small-scale (100 mg-1 g) using a robotic workstation.
使用一套自主研发的自动化合成系统,制备了72个四肽衍生物库,这些是用于合成具有药物吸引力的五肽的起始材料,采用了一种汇聚策略。首先,利用自动化合成工作站大规模(100-1000克)合成了18种二肽,然后使用自动化系统在中等规模(5-10克)合成了72种四肽。每个二肽或四肽均在单个操作周期中使用改良的甲磺酸方法制备,随后在小型规模(100毫克-1克)下利用机器人工作站并行合成了56种五肽的子库。
