synthetic route to gain access to the uvaretin class of chalcone natural products. In this, the construction of a small library was achieved, and the collection was evaluated for cytotoxicity and other biological properties. Uvaretin (1) was accessed via a seven-step route in an overall yield of 15.1%. Within this route, the unsaturated enone variant of uvaretin (2), also a natural product, was accessed
在此,我们公开了合成途径的开发,以获取查尔酮天然产品中的uvaretin类。在这种情况下,实现了一个小型文库的构建,并对该集合的细胞毒性和其他生物学特性进行了评估。通过七步路线获得了Uvaretin(1),总产率为15.1%。在该途径内,通过六个步骤以16.7%的收率获得了也是天然产物的uvaretin(2)的不饱和烯酮变体。与以前的合成路线相比,该路线提供的1和2产量分别提高了将近三倍,而总产量分别为5.8%和3.0%。评估1和图2显示了癌细胞系HeLa,U937,A549和MIA PaCa-2中的IC 50值在2.0和5.1μM之间。整个查耳酮文库集的筛选导致在六个癌细胞系中发现30多种化合物,这些化合物具有唯一的μMIC 50活性。此外,发现多个文库成员具有已知的化学治疗剂有希望的增强特性。
