A library of ten 1,3-diyne-linked peptoids has been synthesized through an Ugi four-component reaction (U-4CR) followed by a copper-catalysed alkyne homocoupling (Glaser reaction). The short and chemoselective reaction sequence allows generating diverse (pseudo) dimeric peptoids. A combinatorial version allows the one-pot preparation of, e.g., six-compound-libraries of homo- and heterodimers verified by ESI-MS and HPLC. In a preliminary evaluation, some compounds display moderate activity against the Gram-positive bacterium Bacillus subtilis.
已经通过 Ugi 四组分反应(U-4CR)和铜催化的炔烃偶联(Glaser 反应)合成了一个包含十个 1,3-二炔基连接的肽的库。这种简短且选择性的反应序列允许生成多样化的(拟)二聚肽。组合版本允许一锅法制备例如同二聚体和异二聚体的六化合物文库,通过 ESI-MS 和 HPLC 进行验证。在初步评估中,一些化合物对革兰氏阳性菌枯草芽孢杆菌显示出中等的活性。
