An approach to the parallel synthesis of hydantoin libraries by reaction of in situ generated 2,2,2-trifluoroethylcarbamates and α-amino esters was developed. To demonstrate utility of the method, a library of 1158 hydantoins designed according to the lead-likeness criteria (MW 200–350, cLogP 1–3) was prepared. The success rate of the method was analyzed as a function of physicochemical parameters of the products, and it was found that the method can be considered as a tool for lead-oriented synthesis. A hydantoin-bearing submicromolar primary hit acting as an Aurora kinase A inhibitor was discovered with a combination of rational design, parallel synthesis using the procedures developed, in silico and in vitro screenings.

并行合成世界中的古老故事：海因肽文库的一种使用方法

开发了一种通过原位生成的2,2,2-三氟乙基氨基甲酸酯与α-氨基酯反应平行合成乙内酰脲文库的方法。为了证明该方法的实用性，准备了根据铅样标准（MW 200–350，cLogP 1-3）设计的1158个乙内酰脲文库。分析了该方法的成功率与产品理化参数的关系，发现该方法可以被认为是用于铅导向合成的工具。通过合理设计，使用开发的方法进行平行合成，计算机模拟和体外筛选相结合的方法，发现了一种含乙内酰脲的超微摩尔主要分子，可作为Aurora激酶A抑制剂。
